Evolutionary significance of the variation in acoustic communication of a cryptic nocturnal primate radiation (Microcebus spp.)

open access: yesEcology and Evolution, 2020
Acoustic phenotypic variation is of major importance for speciation and the evolution of species diversity. Whereas selective and stochastic forces shaping the acoustic divergence of signaling systems are well studied in insects, frogs, and birds ...

Omega-3 fatty acids from fish oil lower anxiety, improve cognitive functions and reduce spontaneous locomotor activity in a non-human primate. [PDF]

open access: yesPLoS ONE, 2011
Omega-3 (ω3) polyunsaturated fatty acids (PUFA) are major components of brain cells membranes. ω3 PUFA-deficient rodents exhibit severe cognitive impairments (learning, memory) that have been linked to alteration of brain glucose utilization or to ...

Observations of daytime activity in the nocturnal northern giant mouse lemur (Mirza zaza)

open access: yesBehaviour, 2020
We provide an anecdote of daytime activity within the northern giant mouse lemur (Mirza zaza), a small threatened primate that has always been considered strictly nocturnal, in the Anabohazo forest of northwestern Madagascar.

Lessons from the analysis of nonhuman primates for understanding human aging and neurodegenerative diseases [PDF]

open access: yes, 2015
Animal models are necessary tools for solving the most serious challenges facing medical research. In aging and neurodegenerative disease studies, rodents occupy a place of choice.

Neurobiological substrates of animal personality and cognition in a nonhuman primate (Microcebus murinus)

open access: yesBrain and Behavior, 2020
Introduction The gray mouse lemur (Microcebus murinus) is an important nonhuman primate model in biomedical research. Numerous studies investigated mouse lemur behavior and possible factors underlying interindividual variation in both, animal personality

A 50‐year perspective on the use and potential of artiodactyl calcanei in bone adaptation studies

open access: yesBiological Reviews, Volume 101, Issue 1, Page 437-485, February 2026.
ABSTRACT Sheep and deer calcanei are important models for studying cortical (compact) and trabecular (cancellous) bone adaptation because they are amenable to direct strain measurement (due to lack of surrounding muscles), experience relatively simple/unidirectional bending, exhibit osteon remodelling, and have the most pronounced regional variations ...

An alu-based phylogeny of lemurs (infraorder: Lemuriformes).

open access: yesPLoS ONE, 2012
LEMURS (INFRAORDER: Lemuriformes) are a radiation of strepsirrhine primates endemic to the island of Madagascar. As of 2012, 101 lemur species, divided among five families, have been described. Genetic and morphological evidence indicates all species are

Darwin and evolution: a set of activities based on the evolution of mammals [PDF]

open access: yes, 2010
These activities, prepared for key stage 5 students (ages 16-18) and also suitable for key stage 4 (ages 14-16), show that physical appearance is not necessarily the best way to classify mammals.
