Microbial Contributions to Primate Reproduction. [PDF]

Evol Anthropol
ABSTRACT Reproduction is a complex process, and microbes play a far greater role than previously imagined. This review explores the ways that microbiomes influence the rich tapestry of reproductive processes and outcomes within the primate lineage, including pre‐copulatory and post‐copulatory mechanisms.

The Earliest Known Radiation of Pitheciine Primates. [PDF]

Am J Primatol
Right mandible and dentition of the holotype of Soriacebus ameghinorum (MACN Pv SC2), from the Early Miocene of Patagonia, compared with the living Cacajao calvus (FMNH 88813, cast), both representing extinct and extant morphologies of the Pitheciinae: Procumbent and styliform incisors and projecting canines represent a morphological complex for ...

Survival rates and mortality risks of Plecturocebus cupreus at the California National Primate Research Center

American Journal of Primatology, Volume 85, Issue 10, October 2023., 2023
This graphical abstract presents a comprehensive survival analysis of male and female titi monkeys at the CNPRC (600 individuals). The top panel features Kaplan–Meier regression curves, capturing survival rates over time, and a breakpoint analysis highlighting a significant change in survival that occurs at 10 years for males and 16 years for females ...

Differences in sperm morphology between Alouatta palliata and Alouatta pigra are consistent with the intensity of sperm competition in each species

American Journal of Primatology, Volume 85, Issue 10, October 2023., 2023
Diagram of measurements taken on sperm cells. Sperm cells were stained with Eosin‐nigrosin, and images were taken at ×200 magnification with a Celestron Digital 5MP microscope camera. The embedded box in the bottom right corner shows the sperm cell without annotation and with a scale bar.

Organization of descending neurons in the brain of the desert locust

Journal of Comparative Neurology, Volume 531, Issue 14, Page 1350-1380, October 2023., 2023
Desert locusts are model organisms for research on olfaction, vision, spatial orientation, and navigation. To facilitate further studies on motor control by the brain, we provide a comprehensive analysis of the number of descending neurons and their innervation areas in the locust brain.

Plasticity and genetic effects contribute to different axes of neural divergence in a community of mimetic Heliconius butterflies

Journal of Evolutionary Biology, Volume 36, Issue 8, Page 1116-1132, August 2023., 2023
Comparing brain morphology across a Panamanian community of Heliconius butterflies, we find evidence for interspecific variation along two axes: heritable divergence in the size of visual brain components, and plastic differences in mushroom body size, a central component of learning and memory systems.

Bone Marrow Is a Major Parasite Reservoir in Plasmodium vivax Infection

mBio, 2018
Plasmodium vivax causes heavy burdens of disease across malarious regions worldwide. Mature P. vivax asexual and transmissive gametocyte stages occur in the blood circulation, and it is often assumed that accumulation/sequestration in tissues is not an ...
