Most mammals do not wander: few species escape continental endemism

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Terrestrial mammals are found nearly everywhere on Earth. Yet, most taxa are endemic to a single continent; geological, evolutionary, ecological, or physiological filters constrain geographic distributions. Here, we synthesize data on geography, taxonomy, lineage age, dispersal, body size, and diet for > 4000 terrestrial mammals prior to detectable ...

SIRENIA FOSSILS FROM QOM FORMATION (BURDIGALIAN) OF THE KABUDAR AHANG AREA, NORTHWEST IRAN

open access: yesRivista Italiana di Paleontologia e Stratigrafia, 2016
Fossil remains of sirenians (Mammalia; Dugongidae) are reported from the late early Miocene (Burdigalian) Qom Formation near the town of Shirin Su, northwest Kabudar Ahang region, west of Tehran, Iran. The fossils consist of partial postcranial skeletons

Diving physiology of marine mammals [PDF]

open access: yes, 2019
Morski sisavci uključuju tri reda: Carnivora (tu spada podred Pinnipedia), Cetacea i Sirenia. Oni imaju jednake karakteristike kao i svi ostali sisavci, ali za razliku od njih imaju brojne prilagodbe koje im omogućuju da provedu duge periode ispod ...

Fossils and living taxa agree on patterns of body mass evolution:A case study with Afrotheria [PDF]

open access: yes, 2015
Most of life is extinct, so incorporating some fossil evidence into analyses of macroevolution is typically seen as necessary to understand the diversification of life and patterns of morphological evolution.

Historical Collections of Tropical Marine Mammals Are an Excellent Resource for Ancient DNA

open access: yesMolecular Ecology Resources, Volume 25, Issue 7, October 2025.
ABSTRACT The ability to predict ancient DNA sequencing success in natural history collections is critical to reducing the amount of destructive sampling of a finite resource. So far, studies investigating such success have predominantly focused on taxa with ranges restricted to temperate or cold environments at northern latitudes, which likely aids DNA

The DEC2‐SCN2A Axis is Essential for the Anticonvulsant Effects of Cannabidiol by Modulating Neuronal Plasticity

open access: yesAdvanced Science, Volume 12, Issue 36, September 25, 2025.
This study identifies DEC2 as a critical transcriptional repressor of Scn2a that directly binds E‐box motifs in its promoter to regulate neuronal plasticity and epileptogenesis. Functional manipulation of DEC2 alters seizure susceptibility in vivo. Cannabidiol enhances this repression, unveiling a novel DEC2‐SCN2A axis underlying its anticonvulsant ...

Dental eruption in afrotherian mammals. [PDF]

open access: yes, 2011
BACKGROUND: Afrotheria comprises a newly recognized clade of mammals with strong molecular evidence for its monophyly. In contrast, morphological data uniting its diverse constituents, including elephants, sea cows, hyraxes, aardvarks, sengis, tenrecs ...

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps)

open access: yesThe Anatomical Record, Volume 308, Issue 9, Page 2413-2432, September 2025.
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

The microbiome of large marine vertebrates [PDF]

open access: yes, 2019
Veliki morski kralježnjaci iznimno su vaţni stanovnici oceanskih ekosustava, a mogu biti domaćini velikom broju mikroorganizama. Sve više istraživanja pokazuje da je mikrobiom, skup svih gena zajednice mikroorganizama, od velike evolucijske vaţnosti za ...
