Evidence of strong stabilizing effects on the evolution of boreoeutherian (Mammalia) dental proportions. [PDF]

, 2019
The dentition is an extremely important organ in mammals with variation in timing and sequence of eruption, crown morphology, and tooth size enabling a range of behavioral, dietary, and functional adaptations across the class.

Giant Gardeners of the Forest: How African Forest Elephants (Loxodonta cyclotis) Shape Mammal Biodiversity in the Republic of Congo

African Journal of Ecology, Volume 63, Issue 3, April 2025.
ABSTRACT The African forest elephant (Loxodonta cyclotis), a critically endangered species, is a megaherbivore that browses and transforms large quantities and varieties of vegetation during its foraging activities and movements. However, the cascading effects of this ‘ecosystem engineer’ on animal biodiversity are poorly known. In this study, based on

Developmental and Sex‐Based Variation in Nest Building Among Wild Immature Chimpanzees

American Journal of Primatology, Volume 87, Issue 3, March 2025.
ABSTRACT All great apes build nests. Nests in trees or on the ground provide apes with a safe and comfortable place to sleep and rest at night and during the day. Nest building is a necessary skill and form of tool use that individuals learn and practice early in life, but little is known about its development and about the factors affecting the ...

Tenim els mateixos cromosomes que els altres primats? [PDF]

, 2014
En aquest treball, els autors ens expliquen de quina manera la introducció durant els anys 70 de noves tècniques analítiques en l'estudi dels cromosomes permet albirar noves possibilitats per establir els mecanismes concrets en la ...

Apocrine glands in the eyelid of primates contribute to the ocular host defense [PDF]

, 2004
Apocrine glands of Moll are regular components of primate eyelids. We studied the distribution and localization of these glands in three different primate species, the common marmoset, the rhesus monkey, and the hamadryas baboon.

Mosquito‐derived ingested DNA as a tool for monitoring terrestrial vertebrates within a peri‐urban environment

Ecosphere, Volume 16, Issue 1, January 2025.
Abstract Global biodiversity is declining at an alarming rate. Consequently, there is a pivotal need to determine the occurrences and distributions of threatened species. Monitoring and detection approaches are traditionally reliant on capture (traps and cameras), as well as observations.

Positive Selection of TLR2 and MyD88 Genes Provides Insights Into the Molecular Basis of Immunological Adaptation in Amphibians

Ecology and Evolution, Volume 14, Issue 12, December 2024.
We found that recurrent positive selection has acted on TLR2 and MyD88 in amphibians and positively selected sites were mainly located at or close to function domains. Our results suggest that amphibians have adapted to different pathogenic microorganisms during their transition from the aquatic to terrestrial environment and diversification into ...

The Scutulum and the Pre‐Auricular Aponeurosis in Bats

Journal of Morphology, Volume 285, Issue 11, November 2024.
The scutulum is not a simple sesamoid element in bats. Its relative size and shape vary amongst taxa. These range from relatively flat structures to derived forms where they exist as socket joints for the pinna during a wide range of movements. This novel modification reduces the area available for the attachment of auricular musculature. To compensate,
