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.

General palaeontology, systematics and evolution (Vertebrate palaeontology) Early Late Miocene insectivores (Eulipotyphla, Mammalia) from the Cañada section (Province of Zaragoza, east Central Spain). [PDF]

, 2012
Vallesian (early Late Miocene) strata from the recently introduced Ca˜nada section (province of Zaragoza, east Central Spain) have yielded fairly large insectivore assemblages. These show that, after the generally dry Aragonian, the Vallesian gave rise

Artificial Irrigation Impacts the Seasonal Occurrence of Pathogenic Leptospira in Its Wild Reservoirs in a Mediterranean Environment

Zoonoses and Public Health, EarlyView.
ABSTRACT Background Human activities play a significant role in the emergence of infectious diseases. We aimed to test whether artificial irrigation affects the occurrence of a zoonotic bacteria sensitive to desiccation, pathogenic Leptospira species (pathoLep), in micromammals inhabiting Mediterranean ecosystems.

Preservation biases in the fossil record distort species ecological niche and distribution models

Ecography, Volume 2026, Issue 3, March 2026.
Ecological niche models (ENMs) increasingly leverage the fossil record to understand species' environmental associations and predict their geographic distributions. However, fossils do not occur uniformly through time and space, which can compromise the robustness of ENMs and thus affect ecological conclusions. Here, we assessed how preservation biases

Dating placentalia: Morphological clocks fail to close the molecular fossil gap [PDF]

, 2016
Dating the origin of Placentalia has been a contentious issue for biologists and paleontologists. Although it is likely that crowngroup placentals originated in the Late Cretaceous, nearly all molecular clock estimates point to a deeper Cretaceous ...

Non-target small mammal communities in invertebrate pitfall traps: effects of season, habitat, and elevation

Folia Oecologica
Despite considerable endeavours of scientists to avoid it, non-target species are frequently trapped for ecological and conservation research. Nevertheless, these data can provide valuable insights into how ecosystems function. Small mammals not targeted

Rapid size change associated with intra-island evolutionary radiation in extinct Caribbean “island-shrews”

BMC Evolutionary Biology, 2020
Background The Caribbean offers a unique opportunity to study evolutionary dynamics in insular mammals. However, the recent extinction of most Caribbean non-volant mammals has obstructed evolutionary studies, and poor DNA preservation associated with ...

Molecular Phylogeny Supports Repeated Adaptation to Burrowing within Small-Eared Shrews Genus of Cryptotis (Eulipotyphla, Soricidae). [PDF]

PLoS ONE, 2015
Small-eared shrews of the New World genus Cryptotis (Eulipotyphla, Soricidae) comprise at least 42 species that traditionally have been partitioned among four or more species groups based on morphological characters.

Biodiversity and Conservation Challenges in the Alédjo Wildlife Reserve (AWR) in Togo: Insights From Ethnozoological Surveys

Ecology and Evolution, Volume 16, Issue 1, January 2026.
The present study analyzes wildlife species use indices and a vulnerability in the Aledjo Wildlife Reserve (AWR) in Togo. The Importance Value‐in‐use Index (IVIUsp) indicates that the most valued species are the patas monkey (Erythrocebus patas), the forest cobra (Naja melanoleuca), and the green mamba (Dendroaspis viridis).
