Argyreia decemloba

Traiperm, Fujikawa & Staples

in Traiperm, Fujikawa, Chitchak, et al., 2019.

DOI: 10.3372/wi.49.49108

Abstract

Argyreia decemloba Traiperm, Fujikawa & Staples, a new species of Convolvulaceae from Natma Taung National Park, Chin State, Myanmar, is described here with detailed illustrations and summaries for its distribution, ecology and IUCN conservation status. This new species is a high-climbing twiner that can be distinguished by a white or pale yellow corolla with a deep red or purple-black colour inside at the base of the tube, a ten-lobed corolla limb, and staminal filament bases expanded and densely covered by hispid hairs. Argyreia decemloba is here assessed as Near Threatened (NT) following IUCN Red List categories.

KEYWORDS: Argyreia, Chin State, Convolvulaceae, filament morphology, Mount Victoria, Myanmar, Natma Taung, new species discovery, SE Asian biodiversity, staminal trichomes, taxonomy

Argyreia decemloba Traiperm, Fujikawa & Staples, sp. nov.

Holotype: Myanmar, Chin State, Mindat Township, ...

Diagnosis — Three species of Argyreia are known to have a white or pale yellow corolla with a deep red or purple-black colour inside at the base of the tube as well as a 10-lobed limb: A. barbata (Wall.) Raizada; A. maymyensis (Lace) Raizada; and A. decemloba (Table 1). Argyreia barbata and A. maymyensis have quite narrow, linear inflorescence- and floral bracts that do not cover up the calyx and corolla base; the hispid-hirsute indumentum of A. barbata, composed of dense, bristly hairs may obscure the floral organs underneath. In contrast, A. decemloba has broad, laminar inflorescence- and floral bracts that cover the floral organs underneath; the abaxial surface of the bracts has a completely different, dimorphic indumentum composed of two different trichome types (Table 1).

Maknoi.

Distribution and ecology — So far known only from Chin State, Myanmar, occurring at elevations of (740–)1025–1200(–1530) m. A high-climbing twiner in trees and shrubs inhabiting open, sunny places such as roadsides, footpaths in secondary forest, edges of deciduous forest, clearings in evergreen forest, and in semi-evergreen forest; preferring moist soils along streams or the banks of rivers. The soil type has not been reported.

Etymology — The specific epithet recognizes the distinctive 10-lobed corolla limb.

Tanichthys kuehnei

Bohlen, Dvorák, Thang & Šlechtová, 2019

DOI: 10.23788/IEF-1081

Tanichthys kuehnei, new species, is described from a stream in the Bach Ma Mountains in Hue Province in Central Vietnam. The new species differs from its congeners by having more branched rays in anal fin (9 1/2 vs. 7-8 1/2 in T. micagemmae and 8 1/2 in T. albonubes and T. thacbaensis). Morphological and genetic characters suggest it to be closer related to T. micagemmae, the only other species of Tanichthys known from Central Vietnam. Tanichthys kuehnei differs from T. micagemmae by having a white anal-fin margin (vs. red).

Drassodella quinquelabecula Tucker, 1923

in Mbo & Haddad, 2019.

DOI: 10.11646/zootaxa.4582.1.1

Abstract

The genus Drassodella Hewitt, 1916 is one of four Afrotropical genera of Gallieniellidae, and is presently represented by seven species, all endemic to South Africa. The type material of six of the described species was studied and they are redescribed from both sexes: D. melana Tucker, 1923, D. quinquelabecula Tucker, 1923, D. salisburyi Hewitt, 1916, D. septemmaculata (Strand, 1909), D. tenebrosa Lawrence, 1938 and D. vasivulva Tucker, 1923. Of these, the males of D. melana, D. tenebrosa and D. vasivulva are described for the first time. Recent field work yielded additional females of D. purcelli Tucker, 1923 from the vicinity of the type locality, and this sex is redescribed; the male remains unknown. A further 12 new species are recognized: D. amatola sp. nov. (♀ ♂), D. aurostriata sp. nov. (♀ ♂),D. baviaans sp. nov. (♂), D. flava sp. nov. (♀ ♂), D. guttata sp. nov. (♀ ♂), D. lotzi sp. nov. (♀), D. maculata sp. nov. (♀), D. montana sp. nov. (♀ ♂), D. tolkieni sp. nov. (♀ ♂), D. trilineata sp. nov. (♀), D. transversa sp. nov. (♀ ♂) andD. venda sp. nov. (♀ ♂). Based on the genitalic structures, there appear to be two distinct species groups. The D. melana species group, which includes D. melana, D. tenebrosa and eight new species mainly distributed in eastern and northern South Africa, is characterised by very conservative genitalic morphology in both sexes. The D. salisburyi species group, with considerable variation in the structure of the copulatory organs and distributed in the southern half of South Africa, includes the remaining nine species, of which four are new. Although D. tenebrosa represents an intermediate between the two groups, with palpal morphology more typical of the D. melana species group and epigynal morphology typical of the D. salisburyi group, it is placed in the former species group based on its distribution in eastern South Africa. The biology, habitat preferences and biogeography of Drassodella are briefly discussed.

Prangos aricakensis

Behçet, Yapar & Olgun, 2019.

DOI: 10.11646/phytotaxa.401.1.5

Abstract

Prangos aricakensis is described and illustrated as a new species from eastern Anatolia (Turkey), where it is known from a single locality in Arıcak (Elazığ) district. Its diagnostic characters are discussed and taxonomic comments are presented. Prangos aricakensis is similar to P. turcica, P. hulusii, P. ilanae and P. trifida, but it differs in hair, leaf, bract, bracteole and fruit characteristics. Fruit and pollen characteristics were investigated using ligth (LM) and scanning electron microscopy (SEM). Data on ecology and IUCN conservation status are also shown.

Tephritis kovalevi kumana

S. Korneyev & V. Korneyev, 2019

DOI: 10.11646/zootaxa.4584.1.1

Abstract

Species of the genus Tephritis usually have the wing pattern with dark rays on veins R4+5 and M connected to the preapical dark spot or to each other (often called the “apical fork). Some species, however, have a solid apical crossband (Korneyev, 2013), whereas others have an isolated pair of apical spots. Specimens with the latter morphological character occasionally occur in many species with typical wing patterns, but in this article we focus on the species that normally have it. They occur mostly in the Palaearctic Region, except T. candidipennis Foote, 1960 from North America. A total of twenty species are recognized in this complex, including three new species and two new subspecies: Tephritis arsenii S. Korneyev, 2015, T. bardanae (Schrank 1803), T. conyzifoliae Merz 1992, T. crepidis Hendel 1927, T. dilacerata (Loew 1846), T. dilacerata kaszabi new subspecies, T. formosa (Loew 1844),T. ghissarica new species, T. hendeliana Hering 1944, T. hyoscyami (Linnaeus 1758), T.kyrghyzica new species, T. kogardtauica Hering 1944, T. kovalevi Korneyev & Kameneva 1990, T. kovalevi kumana new subspecies; T. postica (Loew 1844), T. stictica Loew 1862, T. theryi Séguy 1930, T. tridentata S. Korneyev & Mohamadzade-Namin 2013, T. truncata (Loew 1844), T. valida (Loew 1862), T. youngiananew species, and T. zernyi Hendel 1927. Most of the species are keyed, redescribed and illustrated based on extensive material from the Palaearctic Region. Lectotypes of T. dilacerata, T. formosa, T. hendeliana, T. truncata, T. valida, T. posis, T. heiseri, T. procera and a neotype for T. postica are designated. Known host plants of this complex belong to the tribes Anthemideae, Cardueae, Cichorieae, Inuleae, and Senecioneae (Asteraceae); preliminary comparison of the morphological characters (other than the wing pattern) with the distribution among host plants shows that the flies apparently do not form a monophyletic group, belonging to several different lineages, which also include other species with the typical “forked wing pattern. New distribution records and host plants are reported.

The following synonymies are established: Musca hyoscyami Linnaeus 1758 =Tephritis heiseri Frauenfeld 1865 new synonym; Trypeta postica Loew 1844 = Tephritis posis Hering 1939 new synonym.

Euphorbia longitubicinicyathium J.-P. Castillon & J.-B. Castillon (Euphorbiaceae), a new species from northeastern Madagascar is described and illustrated with field photographs. The new species belongs to Euphorbia sect. Goniostema Baill. ex Boiss. and is morphologically related to non thorny species of the east coast of Madagascar (e.g. Euphorbia geroldii Rauh, Euphorbia robivelonae Rauh or Euphorbia thuarsiana Baill.) but differs by its larger dimensions, its habit and its long trumpet shaped cyathia.

The colubrid snake genus Dendrelaphis comprises of 45 species (Uetz et al. 2018) of which eleven currently occurs in India (Aengals et al. 2018). A member of this genus, Dendrelaphis caudolineatus (Gray, 1834), was once considered a wide-ranging species in Southeast Asia, the Philippines and the Indo-Australian Archipelago, until Van Rooijen & Vogel (2012) resolved taxonomy of this species complex. Now its range is restricted from southern Thailand to Sundaland (Peninsular Malaysia, Sumatra, Billiton and Borneo; presence doubtful in Java of Indonesia) (Van Rooijen & Vogel 2012).

Abstract

Small theropod tracks, ichnogenus Minisauripus, from the Jinju Formation (Cretaceous) of Korea reveal exquisitely preserved skin texture impressions. This is the first report for any dinosaur of skin traces that cover entire footprints, and every footprint in a trackway. Special sedimentological conditions allowed footprint registration without smearing of skin texture patterns which consist of densely-packed, reticulate arrays of small (<0.5 mm) polygons, preserved as both impressions and casts, the latter essentially foot replicas. The skin texture resembles that reported for two Lower Cretaceous avian theropods (birds) from China which had quite different foot morphologies. This is also the oldest report of Minisauripus from Korea predating five reports from the Haman Formation of inferred Albian age. Minisauripus is now known from six Korean and three Chinese localities, all from the Lower Cretaceous. This gives a total sample of ~95 tracks representing ~54 trackways. With >80% of tracks <3.0 cm long, Minisauripus is pivotal in debates over whether small tracks represent small species, as the database suggests, or juveniles of large species.

Abstract

A hominin third metatarsal discovered in 2007 in Callao Cave (Northern Luzon, the Philippines) and dated to 67 thousand years ago provided the earliest direct evidence of a human presence in the Philippines. Analysis of this foot bone suggested that it belonged to the genus Homo, but to which species was unclear. Here we report the discovery of twelve additional hominin elements that represent at least three individuals that were found in the same stratigraphic layer of Callao Cave as the previously discovered metatarsal. These specimens display a combination of primitive and derived morphological features that is different from the combination of features found in other species in the genus Homo (including Homo floresiensis and Homo sapiens) and warrants their attribution to a new species, which we name Homo luzonensis. The presence of another and previously unknown hominin species east of the Wallace Line during the Late Pleistocene epoch underscores the importance of island Southeast Asia in the evolution of the genus Homo.

DOI: 10.11646/phytotaxa.401.2.4

Abstract
Stachytarpheta atkinsiae, belonging to the Radlkoferiana group from the Chapada Diamantina, Bahia state Brazil, is here described. It is a red-flowered species, and unusual in being a large, much-branched shrub, with densely lanate indumentum. The species shows similarities with S. froesii and S. radlkoferiana, but differs from both vegetative and floral characters. We provide a full description of the species, together with illustrations, a conservation status assessment, and a distribution map.

Stachytarpheta atkinsiae Harley & Giul. sp. nov.

Type:— BRAZIL. Bahia: Mucugê, Serra do Gobira, ca. 8,4 km ao sul de Mucugê em linha reta, na última subida próxima ao cume, ...., 1555 m. Campo rupestre entre pedras, 19 January 2005, R.M. Harley, A.M. Giulietti & E. Ribeiro 55488 (holotype HUEFS; Isotypes K, MG, SPF).

Stachytarpheta atkinsiae is morphologically similar to S. froesii Moldenke, S. radlkoferiana Mansfeld var. radlkoferiana and S. radlkoferiana var. lanata S.Atkins. All taxa are red-flowered and those species are the only ones to share with S. atkinsiae the discolorous leaves, ± glabrous on adaxial surface and white-lanate on abaxial surface and with a revolute margin. S. atkinsiae has leaves sessile or with petiole up to 2 mm long, lamina 2.0–3.7 × 1.0–2.3 cm, elliptic, apex obtuse; bracts linear, 10–12.5 mm long; base of flowers obscured by lanate indumentum. S. froesii differs from the new species as follows: it has leaves with petiole 5–8 mm long, lamina 1.5–2.8 × 1.4–2.5 cm, broadly obovate, apex rotund to truncate, base of flowers not obscured by lanate indumentum and especially because the bracts which are linear as in S. atkinsiae, measure only c. 4 mm long. S. radlkoferiana var. radlkoferiana and var. lanata differ from the new species as both possess obovate and not linear bracts, as well as having much smaller, sessile leaves. S. radlkoferiana var. radlkoferiana has imbricate leaves on the young shoots, 0.7–1.5 × 0.4–0.8 cm., linear-elliptic to long-triangular or narrowly oblong, while S. radlkoferiana var. lanata has ovate leaves, which measure 1.0–1.4 × 0.5–0.7 cm.

Distribution and ecology:— S. atkinsiae is known only from the Serra do Gobira, in the municipality of Mucugê, in Bahia (Map 1). The species occurs only in campo rupestre vegetation in sandy rocky dry soils. It is recorded from high elevation areas (1400 to 1570 m) in campo rupestre vegetation, in sandy rocky dry soils. Flowers and fruits were registered in September and January (most collections in this month).

Etymology:— The specific epithet honors Sandy Atkins who worked at the Royal Botanic Gardens, Kew. Sandy Atkins is the author of the revision of Stachytarpheta in Brazil (Atkins 2005), a superb work that is currently the most up-to-date and important contribution to our knowledge of the genus.

Abstract

Since the first discovery of Pithecanthropus (Homo) erectus by E. Dubois at Trinil in 1891, over 200 hominid dentognathic remains have been collected from the Early to Middle Pleistocene deposits of Java, Indonesia, forming the largest palaeoanthropological collection in South East Asia. Most of these fossils are currently attributed to H. erectus. However, because of the substantial morphological and metric variation in the Indonesian assemblage, some robust specimens, such as the partial mandibles Sangiran 5 and Sangiran 6a, were formerly variably allocated to other taxa (Meganthropus palaeojavanicus, Pithecanthropus dubius, Pongo sp.). To resolve the taxonomic uncertainty surrounding these and other contentious Indonesian hominid specimens, we used occlusal fingerprint analysis (OFA) to reconstruct their chewing kinematics; we also used various morphometric approaches based on microtomography to examine the internal dental structures. Our results confirm the presence of Meganthropus as a Pleistocene Indonesian hominid distinct from Pongo, Gigantopithecus and Homo, and further reveal that Dubois’s H. erectus paratype molars from 1891 are not hominin (human lineage), but instead are more likely to belong to Meganthropus.

Abstract
The cephalopod fauna of the southwestern Atlantic is especially poorly-known because sampling is mostly limited to commercial net-fishing operations that are relatively inefficient at obtaining cephalopods associated with complex benthic substrates. Cephalopods have been identified in the diets of many large marine species but, as few hard structures survive digestion in most cases, the identification of ingested specimens to species level is often impossible. Samples can be identified by molecular techniques like barcoding and for cephalopods, mitochondrial 16S and COI genes have proven to be useful diagnostic markers for this purpose. The Amazon River estuary and continental shelf are known to encompass a range of different substrates with recent mapping highlighting the existence of an extensive reef system, a type of habitat known to support cephalopod diversity. The present study identified samples of the cephalopod fauna of this region obtained from the stomachs of red snappers, Lutjanus purpureus, a large, commercially-important fish harvested by fisheries using traps and hook-and-line gear that are capable of sampling habitats inaccessible to nets. A total of 98 samples were identified using molecular tools, revealing the presence of three squid species and eight MOTUs within the Octopodidae, representing five major clades. These include four known genera, Macrotritopus, Octopus, Scaeurgus and Amphioctopus, and one basal group distinct from all known octopodid genera described here as Lepidoctopus joaquini Haimovici and Sales, new genus and species. Molecular analysis of large predatory fish stomach contents was found to be an incredibly effective extended sampling method for biodiversity surveys where direct sampling is very difficult.

Etymology: The genus name is a combination of lepido from scale in Greek, referring to the scaly appearance given by the large almost overlapping papillae (dermal cushions) on its skin giving it a peculiar appearance as if it is covered with scales, and octopus. The name joaquini refers to the young son of the first author of this paper (João Bráullio de Luna Sales).

Abstract

A new species, Allium albanicum, is described and illustrated from Albania (Balkan Peninsula). It grows on serpentines or limestone in open rocky stands with a scattered distribution, mainly in mountain locations. Previously, the populations of this geophyte were attributed to A. meteoricum Heldr. & Hausskn. ex Halácsy, described from a few localities of North and Central Greece. These two species indeed show close relationships, chiefly regarding some features of the spathe valves, inflorescence and floral parts. They also share the same diploid chromosome number 2n =16 and similar karyotype, while seed testa micro-sculptures and leaf anatomy reveal remarkable differences. There are also several morphological features that allow them to be differentiated at specific level. The inclusion of both species into a newly described section Pseudoscorodon of the subgen. Allium is proposed. An analytic key to the species, included in the new section, is also provided.

Abstract

Chromis tingting sp. nov., is described on the basis of the holotype and three paratypes from Sagami Bay, Japan. The new species likely belongs to a complex consisting of C. mirationis, C. okamurai and C. struhsakeri, with which it shares the following character combination: dorsal rays XIV,13–14; anal rays II,12; pectoral rays 19–20; tubed lateral-line scales 15–17; two spinous procurrent rays dorsally and ventrally in the caudal fin; and a generally silvery white adult coloration. The new species differs from the other members of its complex in coloration details (particularly in juvenile coloration), and in having fewer gill rakers (5–6 + 17–20 = 22–26), and a larger eye -(13.7–19.4 % SL). The new species has previously been confused with Chromis mirationis, and the contention is herewith briefly discussed.

ABSTRACT

Hyainailourine hyaenodonts are among the largest terrestrial carnivorous mammals known. The clade is widely dispersed, found in Eurasia, North America, and Afro-Arabia in the Paleogene and early Neogene. In this study, we describe dental and postcranial material from Simbakubwa kutokaafrika, gen. et sp. nov., the most complete hyainailourine known from sub-Saharan Africa. The material is from a relatively young adult from the early Miocene locality of Meswa Bridge, Kenya. Simbakubwa differs from Hyainailouros in exhibiting lingually oriented molar protocones, gracile metastyles, and buccolingually compressed, shearing canines. Like other large Miocene hyainailourines, Simbakubwa has deep carnassial notches on the molars and tall paracones fused to shorter metacones forming single piercing cusps. A Bayesian phylogenetic analysis recovers Simbakubwa as the sister taxon of a clade of large-bodied Miocene hyainailourines that includes Hyainailouros and Megistotherium. Bayesian ancestral state reconstruction supports an Afro-Arabian origin for Hyainailourinae with subsequent dispersal to Eurasia during the early Miocene. Regression analysis based on carnassial size is applied to Simbakubwa and closely related hyainailourines, recovering a body mass up to 1,500 kg for the new taxon. The evolution and extinction of Hyainailourinae offers important insights for interpreting ecological transitions from Paleogene to Neogene faunas in Afro-Arabia and Eurasia.

PLAIN LANGUAGE SUMMARY

Hyainailourines were some of the largest mammalian carnivores to ever walk the earth. In this study we describe a new hyainailourine from Kenya, Simbakubwa kutokaafrika. Simbakubwa kutokaafrika, whose name means “Big lion from Africa” in Swahili, was the size of a small rhinoceros and lived about 23 million years ago. The hyainailourine lineage is part of Hyaenodonta, a diverse group of meat-eating mammals unrelated to hyenas that lived in Eurasia, North America, and Africa for the first three-quarters of the Age of Mammals. We estimated the size of Simbakubwa using beautifully preserved teeth that were discovered at Meswa Bridge, an important fossil site in Kenya that also preserves evidence of our early ape relatives. Most of Simbakubwa’s close relatives are known from worn and scrappy fossils. Simbakubwa makes it easier to interpret fragmentary hyainailourine material from Eurasia and Africa. We used the new specimens to place Simbakubwa in the hyaenodont family tree. Based on our analysis, giant hyainailourines originated in Africa about 30 million years ago and they moved into northern ecosystems multiple times before going extinct about ten million years ago. The Miocene, the epoch when giant hyainailourines reigned, was a time of massive tectonic and ecological change as Africa collided with Eurasia, lineages encountered each by crossing the newly formed land bridge, grasslands expanded, and the evolving East African Rift changed climate patterns. The discovery of Simbakubwa offers new insights into how carnivorous mammals adapted to these dramatic changes and gave rise to the modern African ecosystem.

Abstract

Aim: The Lesser Sunda Islands are situated between the Sunda and Sahul Shelves, with a linear arrangement that has functioned as a two‐way filter for taxa dispersing between the Asian and Australo‐Papuan biogeographical realms. Distributional patterns of many terrestrial vertebrates suggest a stepping‐stone model of island colonization. Here we investigate the timing and sequence of island colonization in Asian‐origin fanged frogs from the volcanic Sunda Arc islands with the goal of testing the stepping‐stone model of island colonization.

Location: The Indonesian islands of Java, Lombok, Sumbawa, Flores and Lembata.

Taxon: Limnonectes dammermani and L. kadarsani (Family: Dicroglossidae)

Methods:

Mitochondrial DNA was sequenced from 153 frogs to identify major lineages and to select samples for an exon‐capture experiment. We designed probes to capture sequence data from 974 exonic loci (1,235,981 bp) from 48 frogs including the outgroup species, L. microdiscus. The resulting data were analysed using phylogenetic, population genetic and biogeographical model testing methods.

Results:

The mtDNA phylogeny finds L. kadarsani paraphyletic with respect to L. dammermani, with a pectinate topology consistent with the stepping‐stone model. Phylogenomic analyses of 974 exons recovered the two species as monophyletic sister taxa that diverged ~7.6 Ma with no detectable contemporary gene flow, suggesting introgression of the L. dammermani mitochondrion into L. kadarsani on Lombok resulting from an isolated ancient hybridization event ~4 Ma. Within L. kadarsani, the Lombok lineage diverged first while the Sumbawa and Lembata lineages are nested within a Flores assemblage composed of two parapatrically distributed lineages meeting in central Flores. Biogeographical model comparison found strict stepping‐stone dispersal to be less likely than models involving leap‐frog dispersal events.

Main conclusions:

These results suggest that the currently accepted stepping‐stone model of island colonization might not best explain the current patterns of diversity in the archipelago. The high degree of genetic structure, large divergence times, and absent or low levels of migration between lineages suggests that L. kadarsani represents five distinct species.

Gobihadros mongoliensis

Tsogtbaatar, Weishampel, Evans & Watabe, 2019

DOI: 10.1371/journal.pone.0208480

Abstract

A new genus and species of non-hadrosaurid hadrosauroid, Gobihadros mongoliensis, is described from a virtually complete and undeformed skull and postcranial skeleton, as well as extensive referred material, collected from the Baynshire Formation (Cenomanian-Santonian) of the central and eastern Gobi Desert, Mongolia. Gobihadros mongoliensis is the first non-hadrosaurid hadrosauroid from the Late Cretaceous of central Asia known from a complete, articulated skull and skeleton. The material reveals the skeletal anatomy of a proximate sister taxon to Hadrosauridae in remarkable detail. Gobihadros is similar to Bactrosaurus johnsoni and Gilmoreosaurus mongoliensis, but can be distinguished from them in several autapomorphic traits, including the maximum number (three) of functional dentary teeth per tooth position, a premaxillary oral margin with a ‘double-layer morphology’, and a sigmoidal dorsal outline of the ilium with a well-developed, fan-shaped posterior process. All of these characters in Gobihadros are inferred to be convergent in Hadrosauridae. Phylogenetic analysis positions Gobihadros mongoliensis as a Bactrosaurus-grade hadrosauromorph hadrosauroid. Its relationship with Maastrichtian hadrosaurids from Asia (e.g., Saurolophus angustirostris, Kerberosaurus manakini, Wulagasaurus dongi, Kundurosaurus nagornyi) are sufficiently distant to indicate that these latter taxa owe their distribution to migration from North America across Beringia, rather than having a common Asian origin with Go. mongoliensis.

Abstract

Cnemaspis nilagirica was described by Manamendra-Arachchi, Batuwita and Pethiyagoda in 2007 based on a single female specimen that was a syntype of Gonatodes kandianus var. tropidogaster described by Boulenger in 1885. However, a living population of this species has not been reported since its original description by Boulenger. Based on fresh material and comparisons with the holotype of C. nilagirica, we here report the collection of this species after over 130 years. We provide the first description of a male specimen and additional information on morphological variation, distribution and natural history.
