Conservation Science and Practice, EarlyView.Abstract Bird communities in oceanic islands tend to evolve under reduced predation, making them extremely susceptible to introduced predators. Príncipe Island (São Tomé and Príncipe, Central Africa) harbors 11 endemic bird species and eight introduced mammal species.

Uppermost Pleistocene shrews (Mammalia, Soricidae) from Vaskapu Cave (N-Hungary) [PDF]
, 1999 Three shrew species (Sorex araneus LINNAEUS1758, Sorex minutus LlNNAEUS1766 and Sorex alpinus SHINZ1837) were found in the fossiliferous sediments of Vaskapu Cave, near Felsötárkány.

Intra- and Interspecies Analyses of the Carcinoembryonic Antigen (CEA) Gene Family Reveal Independent Evolution in Primates and Rodents [PDF]
, 1989 Various rodent and primate DNAs exhibit a stronger intra- than interspecies cross-hybridization with probes derived from the N-terminal domain exons of human and rat carcinoembryonic antigen (CEA)-like genes.

Journal of Anatomy, EarlyView.We investigated the internal joint distances (IJDs) of the humero‐ulnar and humero‐radial joint, within a sample of 15 small‐ to medium‐sized mammals and report isometric results. We also found that joint poses had no effect on IJDs and that IJDs scale isometrically within small species.

Spiking Dynamics during Perceptual Grouping in the Laminar Circuits of Visual Cortex [PDF]
, 2009 Grouping of collinear boundary contours is a fundamental process during visual perception. Illusory contour completion vividly illustrates how stable perceptual boundaries interpolate between pairs of contour inducers, but do not extrapolate from a ...

Historical shifts, geographic biases, and biological constraints shape mammal species discovery
Journal of Systematics and Evolution, EarlyView.Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.Androlaelaps fahrenhoizi, a potential vector of zoonotic diseases, is widely distributed in southwest China, predominantly infesting A. agrarius mice. The mite infestation is aggregated, and has environmental heterogeneity and age bias of hosts. Abundant A.

Histaminergic system in the tree shrew brain
Journal of Comparative Neurology, 1989 AbstractThis study mapped the histamine‐immunoreactive neuronal system in the brain of the tree shrew (Tupaia belangeri) and compared its structure with that of the rat and guinea pig. The histamine‐containing cell bodies lay in the posterior ventral hypothalamus in the tuberomammillary complex, as in the rodents.

On the Relation Between Receptive Field Structure and Stimulus Selectivity in the Tree Shrew Primary Visual Cortex [PDF]
, 2017 There are notable differences in functional properties of primary visual cortex (V1) neurons among mammalian species, particularly those concerning the occurrence of simple and complex cells and the generation of orientation selectivity. Here, we present
