The first hyaenodont from the late Oligocene Nsungwe Formation of Tanzania: Paleoecological insights into the Paleogene-Neogene carnivore transition.

Autor: Matthew R Borths, Nancy J Stevens

Publikováno v: PLoS ONE, Vol 12, Iss 10, p e0185301 (2017)

Throughout the Paleogene, most terrestrial carnivore niches in Afro-Arabia were occupied by Hyaenodonta, an extinct lineage of placental mammals. By the end of the Miocene, terrestrial carnivore niches had shifted to members of Carnivora, a clade wit

Oligocene Termite Nests with In Situ Fungus Gardens from the Rukwa Rift Basin, Tanzania, Support a Paleogene African Origin for Insect Agriculture.

Autor: Eric M Roberts, Christopher N Todd, Duur K Aanen, Tânia Nobre, Hannah L Hilbert-Wolf, Patrick M O'Connor, Leif Tapanila, Cassy Mtelela, Nancy J Stevens

Publikováno v: PLoS ONE, Vol 11, Iss 6, p e0156847 (2016)

Based on molecular dating, the origin of insect agriculture is hypothesized to have taken place independently in three clades of fungus-farming insects: the termites, ants or ambrosia beetles during the Paleogene (66-24 Ma). Yet, definitive fossil ev

The earliest colubroid-dominated snake fauna from Africa: perspectives from the Late Oligocene Nsungwe Formation of southwestern Tanzania.

Autor: Jacob A McCartney, Nancy J Stevens, Patrick M O'Connor

Publikováno v: PLoS ONE, Vol 9, Iss 3, p e90415 (2014)

The extant snake fauna has its roots in faunal upheaval occurring across the Paleogene-Neogene transition. On northern continents, this turnover is well established by the late early Miocene. However, this transition is poorly documented on southern

First dinosaur tracks from the Arabian Peninsula.

Autor: Anne S Schulp, Mohammed Al-Wosabi, Nancy J Stevens

Publikováno v: PLoS ONE, Vol 3, Iss 5, p e2243 (2008)

BackgroundThe evolutionary history of Mesozoic terrestrial vertebrates from the Arabian Peninsula is virtually unknown. Despite vast exposures of rocky outcrops, only a handful of fossils have yet been described from the region. Here we report a mult

Closing staffing gaps in Madagascar's protected areas to achieve the 30 by 30 conservation target

Autor: Domoina J. Rakotobe, Nancy J. Stevens

Publikováno v: Conservation Science and Practice, Vol 6, Iss 5, Pp n/a-n/a (2024)

Abstract Protected areas (PAs) guard critical biodiversity and provide ecosystem services, serving as a pillar of the Kunming‐Montreal Global Biodiversity Framework that aims to protect 30% of the planet by 2030. But most PAs are understaffed. This

Living at the edge: home range patterns of the Buraiga Chimpanzee Community, Kibale National Park, Uganda

Autor: Wren I. Edwards, Viorel D. Popescu, Nelson Guma, Hillary Agaba, Godfrey Balyesiima, Lydia Nakami, Nancy J. Stevens

Publikováno v: Frontiers in Ecology and Evolution, Vol 11 (2023)

Data on space-use patterns are essential for understanding species ecology and conservation. Individual chimpanzee communities are known to vary in home range size and habitat use dynamics, reflecting site-specific strategies to differences in resour

Macroscelideans (Myohyracinae and Rhynchocyoninae) from the late Oligocene Nsungwe formation of the Rukwa Rift Basin, southwestern Tanzania

Autor: Cassy Mtelela, Eric M. Roberts, Nancy J. Stevens, Patrick M. O'Connor

Publikováno v: Historical Biology. 34:604-610

The fossil record of macroscelidean mammals is notoriously patchy, with a significant spatial and temporal gap separating faunas from the early Oligocene localities of northern Africa and the early...

A new assemblage of Cenozoic lungfishes (Dipnoi: Lepidosirenidae) from the late Oligocene Nsungwe Formation, Rukwa Rift Basin, southwestern Tanzania

Autor: Eric M. Roberts, Nancy J. Stevens, Patrick M. O'Connor, Sifa Ngasala, Kerin M. Claeson, Michael D. Gottfried

Publikováno v: Geobios. :7-14

Lungfish (Dipnoi) date back to the Devonian, and some fossil taxa as well as extant African lungfishes are known for their ability to aestivate, tolerating low-oxygen environments associated with seasonal drying. Extant lungfishes are separated into
