The evolution of eccrine sweat glands in human and nonhuman primates by Best, Andrew, Kamilar, Jason M.

“…Sweating is an unusual thermoregulatory strategy for most mammals, yet is critical for humans. This trait is commonly hypothesized to result from human…”

Strong influence of palaeoclimate on the structure of modern African mammal communities by Rowan, John, Kamilar, Jason M., Beaudrot, Lydia, Reed, Kaye E.

“…Ecological research often assumes that species are adapted to their current climatic environments. However, climate fluctuations over geologic timescales have…”

Climate and species richness predict the phylogenetic structure of African mammal communities by Kamilar, Jason M, Beaudrot, Lydia, Reed, Kaye E

“…We have little knowledge of how climatic variation (and by proxy, habitat variation) influences the phylogenetic structure of tropical communities. Here, we…”

Eye shape and the nocturnal bottleneck of mammals by Hall, Margaret I., Kamilar, Jason M., Kirk, E. Christopher

“…Most vertebrate groups exhibit eye shapes that vary predictably with activity pattern. Nocturnal vertebrates typically have large corneas relative to eye size…”

Does facial hair greying in chimpanzees provide a salient progressive cue of aging? by Tapanes, Elizabeth, Anestis, Stephanie, Kamilar, Jason M, Bradley, Brenda J

“…The greying of human head hair is arguably the most salient marker of human aging. In wild mammal populations, greying can change with life history or…”

Host longevity and parasite species richness in mammals by Cooper, Natalie, Kamilar, Jason M, Nunn, Charles L

“…Hosts and parasites co-evolve, with each lineage exerting selective pressures on the other. Thus, parasites may influence host life-history characteristics,…”

The climatic niche diversity of malagasy primates: a phylogenetic perspective by Kamilar, Jason M, Muldoon, Kathleen M

“…Numerous researchers have posited that there should be a strong negative relationship between the evolutionary distance among species and their ecological…”

Cultural assemblages show nested structure in humans and chimpanzees but not orangutans by Kamilar, Jason M., Atkinson, Quentin D.

“…The evolution of hominin culture is well-documented in the archeological and fossil record, but such a record is largely absent for nonhuman primates. An…”

Phylogenetic signal in primate behaviour, ecology and life history by Kamilar, Jason M., Cooper, Natalie

“…Examining biological diversity in an explicitly evolutionary context has been the subject of research for several decades, yet relatively recent advances in…”

Great ranging associated with greater reproductive investment in mammals by Pontzer, Herman, Kamilar, Jason M

“…Most animals must travel to find food, incurring an unavoidable energy and time cost. Economic theory predicts, and experimental work confirms, that within…”

Hair Microbiome Diversity within and across Primate Species by Kitrinos, Catherine, Bell, Rachel B, Bradley, Brenda J, Kamilar, Jason M

“…Primate hair and skin are substrates upon which social interactions occur and are host-pathogen interfaces. While human hair and skin microbiomes display body…”

Interspecific Variation in Primate Countershading: Effects of Activity Pattern, Body Mass, and Phylogeny by Kamilar, Jason M

“…Countershading is defined as an animal displaying a dark dorsal and light ventral surface. This color pattern is found in numerous species, yet there are…”

Did Trichromatic Color Vision and Red Hair Color Coevolve in Primates? by KAMILAR, JASON M., HEESY, CHRISTOPHER P., BRADLEY, BRENDA J.

“…Reddish pelage and red hair ornaments have evolved many times, independently, during primate evolution. It is generally assumed that these red‐coat phenotypes,…”
