746 Projects

Media are grouped by projects created by users. Projects tend to contain media tied together by a theme. A project might represent the dataset for a single peer-reviewed paper, the results of a collections digitization project, or data for a digital lesson plan.

Projects can be used to share media ownership and access between project members, and projects can also be used to publish assortments of media and specimens for access and discovery by the public. If you want to share media ownership and access with multiple users across multiple projects, consider creating a user team. Projects can be managed by teams, and users with access to that team also gain access to any projects managed by that team.

Display all details of Diamond frogs forever: A new species of Rhombophryne Boettger, 1880 (Microhylidae, Cophylinae) from Montagne d’Ambre National Park, north Madagascar Although taxonomic progress on the frogs of Madagascar is currently proceeding at an unprecedented pace, the goal of completing the amphibian inventory of this hyper-diverse island is still far off. In part this is because more new species continue to be discovered at a high rate, in some cases within well-studied areas. Here, I describe Rhombophryne ellae sp. nov., a new species of diamond frog discovered in Montagne d’Ambre National Park in the north of Madagascar in 2017. This new species is highly distinctive in having orange flash-markings on its hindlimbs (not known from any described Rhombophryne), and large, black inguinal spots (larger than in all other described Rhombophryne species). It is separated from all named Rhombophryne by a substantial uncorrected pairwise distance in the 16S rRNA mitochondrial barcode marker (>7%), and is most closely related to an undescribed candidate species from Tsaratanana in northern Madagascar. Rhombophryne ellae sp. nov. adds another taxon to the growing list of cophyline microhylids that have red to orange flash-markings, the function of which remains unknown and which has clearly evolved repeatedly in this radiation. The discovery of such a distinctive species within such a well-studied park points toward the low detectability of semi-fossorial frogs, and the role of inclement weather in increasing that detectability. 1 1
Display all details of Baltorussus total makeover: rejuvenation and sex change in an ancient parasitoid wasp lineage The Orussidae is a small and rare but phylogenetically important family of parasitoid wasps. The fossil record of the family is also very poor. Baltorussus velteni was described from Baltic amber from an allegedly female specimen. This and another recently discovered specimen are examined with microCT scanning and standard microscopy. We reveal that both the holotype and the new specimen are actually males. 1 1

Display all details of Hyainailourine and teratodontine cranial material from the late Eocene of Egypt and the application of parsimony and Bayesian methods to the phylogeny and biogeography of Hyaenodonta (Placentalia, Mammalia) Hyaenodonta is a diverse, extinct group of carnivorous mammals that included weasel- to rhinoceros-sized species. The oldest-known hyaenodont fossils are from the middle Paleocene of North Africa and the antiquity of the group in Afro-Arabia lead to the hypothesis that it originated there and dispersed to Asia, Europe, and North America. Here we describe two new hyaenodont species based on the oldest hyaenodont cranial specimens known from Afro-Arabia. The material was collected from the latest Eocene Locality 41 (L-41, ~34 Ma) in the Fayum Depression, Egypt. Akhnatenavus nefertiticyon sp. nov. has specialized, hypercarnivorous dentition and an elongate cranial vault. In A. nefertiticyon the tallest, piercing cusp on M1–M2 is the paracone. Brychotherium ephalmos gen. et sp. nov. has more generalized dentition that retain the metacone and complex talonids on M1–M3. In B. ephalmos the tallest, piercing cusp on M1–M2 is the metacone. We incorporate this new material into a series of phylogenetic analyses using a character- taxon matrix that includes novel dental, cranial, and postcranial characters, and samples extensively from the global record of the group. The phylogenetic analysis includes the first application of Bayesian methods to hyaenodont relationships. B. ephalmos is consistently placed within Teratodontinae, an Afro-Arabian clade with several generalist and hypercarnivorous forms, and Akhnatenavus is consistently recovered in Hyainailourinae as part of an Afro-Arabian radiation. The phylogenetic results suggest that hypercarnivory evolved independently three times within Hyaenodonta: in Teratodontinae, in Hyainailourinae, and in Hyaenodontinae. Teratodontines are consistently placed in a close relationship with Hyainailouridae (Hyainailourinae + Apterodontinae) to the exclusion of “proviverrines,” hyaenodontines, and several North American clades, and we propose that the superfamily Hyainailouroidea be used to describe this relationship. Using the topologies recovered from each phylogenetic method, we reconstructed the biogeographic history of Hyaenodonta using parsimony optimization, likelihood optimization, and Bayesian Binary MCMC to examine support for the Afro-Arabian origin of Hyaenodonta. Across all analyses, we found that Hyaenodonta most likely originated in Europe, rather than Afro-Arabia. The clade is estimated by tip-dating analysis to have undergone a rapid radiation in the Late Cretaceous and Paleocene, a radiation currently not documented by fossil evidence. During the Paleocene, lineages are reconstructed as dispersing to Asia, Afro-Arabia, and North America. The place of origin of Hyainailouroidea is likely Afro-Arabia according to the Bayesian topologies but it is ambiguous using parsimony. All topologies support the constituent clades — Hyainailourinae, Apterodontinae, and Teratodontinae — as Afro-Arabian and tip-dating estimates each clade is established in Afro-Arabia by the middle Eocene. 0 0
Display all details of The sister group of Aculeata (Hymenoptera) – evidence from internal head anatomy The Aculeata comprises some of the best known Hymenoptera. Traditionally, their sister group has been considered to be the Ichneumo-noidea, however, recent phylogenetic analyses contradict this hypothesis. We evaluate three potential candidates for the sister group of aculeate wasps: Ichneumonoidea, Evanioidea and Trigonaloidea. This is addressed by investigating the internal head anatomy of repre-sentatives of the relevant taxa, specifically the tentorium, musculature and glands. One species each of the families Braconidae, Evaniidae, Gasteruptiidae, Aulacidae and Trigonalidae, as well as Sphecidae and Sapygidae as representatives of Aculeata, and Ibaliidae as outgroup is examined. 33 head anatomical characters are mapped on the three competing hypotheses. Aculeata + Evanioidea are corroborated by the presence of a secondary bridge, the presence of a subforaminal cup and the presence of one medial sulcus on the ventral head sclerotisation instead of two sublateral ones. Trigonaloidea + (Aculeata + Evanioidea) is corroborated by the presence of a bent cibarium. The presence of a hypopharyngeal gland, the backwards shift of the origin of the antennal muscles, the loss of the connection of the dorsal tentorial arms with the head capsule and the loss of ventral salivarial dilators are retrieved as synapomorphies of Aculeata. Two hitherto unknown glands, a hypopharyngeal salivary gland in Sphecidae and Sapygidae and a hypopharyngeal-maxillary gland in Evaniidae, are described. 7 7
Display all details of Gonzales Skull Project This project includes scans of strepsirrhine, platyrrhine and cercopithecine skulls that were collected by Lauren A. Gonzales for research on the inner ear (2014-2016). This work was funded by the LSB Leakey Foundation. Osteological specimens (for strepsirrhines and platyrrhines) are currently housed in collections at the American Museum of Natural History (AMNH) in New York, NY and also at the National Museum of Natural History (USNM) in Washington DC. All skulls were scanned at the Shared Instruments Facility (SMIF) at Duke University. All Chlorocebus skulls are part of a wild shot population from Rusinga Island, Kenya. Additional information, including body mass estimates, can be obtained by contacting Brenda Benefit ( Acknowledgement that these scans are the property of the AMNH, USNM and/or Brenda Benefit is required for any publication resulting from the analysis of any of these scans. Cranial capacity for all specimens is available upon request. 477 200
