Turbinal bones are still one of the last frontiers of the tetrapod skull: hypotheses, challenges and perspectives

Biological Reviews, Volume 99, Issue 6, Page 2304-2337, December 2024.
ABSTRACT Turbinals are bony or cartilaginous structures that are present in the nasal cavity of most tetrapods. They are involved in key functions such as olfaction, heat, and moisture conservation, as well as protection of the respiratory tract. Despite recent studies that challenged long‐standing hypotheses about their physiological and genomic ...

TetraDENSITY 2.0—A Database of Population Density Estimates in Tetrapods

Global Ecology and Biogeography, Volume 33, Issue 12, December 2024.
ABSTRACT Motivation Population density is a fundamental parameter in ecology and conservation, and taxonomic and geographic patterns of population density have been an important focus of macroecological research. However, population density data are time‐consuming and costly to collect, so their availability is limited.

Elephants develop wrinkles through both form and function

Royal Society Open Science
The trunks of elephants have prominent wrinkles from their base to the very tip. But neither the obvious differences in wrinkles between elephant species nor their development have been studied before.

Resolution of the type material of the Asian elephant, Elephas maximus Linnaeus, 1758 (Proboscidea, Elephantidae) [PDF]

, 2014
The understanding of Earth’s biodiversity depends critically on the accurate identification and nomenclature of species. Many species were described centuries ago, and in a surprising number of cases their nomenclature or type material remain unclear ...

Assessment of Changes in the Composition and Distribution of Large and Medium‐Sized Mammals in Xishuangbanna, Southwest China

Ecology and Evolution, Volume 14, Issue 11, November 2024.
We employed 785 camera traps to precisely assess large and medium‐sized mammal composition and distribution in tropical Xishuangbanna. Our findings highlight the uneven distribution of large and medium‐sized mammal communities in Xishuangbanna, with rare and large‐sized species being more vulnerable to rapid environmental changes.

Los gonfotéridos (Mammalia, Proboscidea) de Uruguay: taxonomía, estratigrafía y cronología

Estudios Geologicos, 2015
En Uruguay se han hallado numerosos aunque relativamente fragmentarios restos de Gomphotheriidae. Pertenecientes a esta familia existen materiales asignados a la Formación Camacho (Mioceno tardío), y a unidades del Pleistoceno y Holoceno temprano ...

Cutaneous eccrine glands of the foot pads of the rock hyrax (Procavia capensis, Hyracoidea, mammalia) [PDF]

, 2002
In order to find correlations between skin gland morphology and specific ethological features, the cutaneous glands of the foot pads of Procavia capensis were studied by histological and various histochemical methods and by electron microscopy.

A NEW OLIGO-MIOCENE MAMMAL-BEARING SITE FROM A SEDIMENTARY INTERCALATION IN THE TRAP BASALTS OF CENTRAL ERITREA.

Rivista Italiana di Paleontologia e Stratigrafia, 2012
We report the findings of two proboscideans from a sedimentary intercalation within the Central Eritrea Tertiary Trap basalt succession. These intertrappean sediments can be traced continuously between Tera’emni and Adi Quala in the Mendefera region, and

A new estimate of afrotherian phylogeny based on simultaneous analysis of genomic, morphological, and fossil evidence

BMC Evolutionary Biology, 2007
Background The placental mammalian clade Afrotheria is now supported by diverse forms of genomic data, but interordinal relationships within, and morphological support for, the group remains elusive.

Further revision of the fossil Elephantidae of Southern Africa [PDF]

, 1961
NoneThe South African fossil Metarchidiskodon griqua is regarded as indeterminable and hence as a nomen vanum; the generic name thus also falls away. A new method for representing graphically the main dimensional features of elephant molar teeth is ...
