Alston, J. M., Fleming, C. H., Kays, R., Streicher, J. P., Downs, C. T., Ramesh, T., & Calabrese, J. M. (2022, April 22).

TL;DR: This study introduces a method for likelihood weighting of animal locations to mitigate the negative consequences of autocorrelation on resource selection functions, and demonstrates that this method weights each observed location in an animal’s movement track according to its level of non-independence, expanding confidence intervals and reducing bias that can arise when there are missing data in the movement track.

Local host-tick coextinction in neotropical forest fragments

International Journal for Parasitology, 49(3-4), 225–233.

author keywords: Biodiversity loss; Host-parasite interactions; Forest fragmentation; Defaunation; Extinction cascade; Host specificity; Panama
MeSH headings : Animals; Animals, Wild / growth & development; Biodiversity; Extinction, Biological; Forests; Panama; Ticks / growth & development; Tropical Climate; Vertebrates / growth & development
TL;DR: These findings support the host-parasite coextinction hypothesis, and indicate that loss of wildlife can indeed have cascading effects on tick communities, and imply that opportunities for pathogen transmission via generalist ticks may be higher in habitats with degraded tick communities.

Carnivore coexistence: America's recovery

Gompper, M. E., Belant, J. L., & Kays, R. (2015, January 23).

By: M. Gompper*, J. Belant* & R. Kays n

MeSH headings : Animals; Conservation of Natural Resources; Humans; Lynx; Mustelidae; Ursidae; Wolves
TL;DR: In their Report “Recovery of large carnivores in Europe's modern human-dominated landscapes” (19 December 2014), G. Chapron et al. attribute the return of predators in Europe to a “coexistence” model for conservation, in which carnivores and humans inhabit shared landscapes. (via Semantic Scholar)

Mesopredator release facilitates range expansion in fisher

By: S. LaPoint*, J. Belant* & R. Kays n

author keywords: fisher; mesocarnivore; mesopredator release hypothesis; intraguild predation; predator communities; meta-analysis; range contraction; range expansion
TL;DR: Data support the hypothesis that a reduced predator community is contributing to the geographic variation in modern fishers' range expansion, and measurements of museum specimens suggest that individuals within released populations have evolved a larger body size since the time of their most contracted range, which may help them hunt larger prey species that are expected to be more available in the absence of larger carnivores.

A genome-wide perspective on the evolutionary history of enigmatic wolf-like canids

MeSH headings : Animals; Biological Evolution; Canidae / genetics; Coyotes / genetics; Dogs / genetics; Evolution, Molecular; Genome; Genotype; Haplotypes; Hybridization, Genetic; Phenotype; Polymorphism, Single Nucleotide; Wolves / genetics
TL;DR: It is found that these enigmatic canids are highly admixed varieties derived from gray wolves and coyotes, respectively, and divergent genomic history suggests that they do not have a shared recent ancestry as proposed by previous researchers. (via Semantic Scholar)

Causes of mortality in North American populations of large and medium-sized mammals

[Review of ]. ANIMAL CONSERVATION, 14(5), 474–483.

By: C. Collins* & R. Kays*

author keywords: cause-specific mortality; human-footprint; anthropogenic; hunting; predation; vehicle collision; mammals
TL;DR: It is suggested that humans cause most mortalities observed in larger mammals in North America, suggesting that anthropogenic mortalities may represent strong selective forces for animal populations and offer mechanistic support for rapid evolutionary shifts in behavior and morphology in response to human caused changes to the landscape.

Emergence Time and Foraging Activity in Pallas' Mastiff Bat,Molossus molossus(Chiroptera: Molossidae) in Relation to Sunset/Sunrise and Phase of the Moon

Acta Chiropterologica, 13(2), 399–404.

By: R. Holland*, C. Meyer*, E. Kalko*, R. Kays* & M. Wikelski*

author keywords: Molossus molossus; emergence; foraging; nocturnal; predator pressure; activity
TL;DR: The velvety free-tailed bat Molossus molossus emerges just after sunset and just before sunrise for very short foraging bouts (average 82.2 min foraging per night) and this data suggests that M. molossus represents an example of an aerial hawking bat whose foraging behaviour is in fact adapted to the compromise between the need to exploit highest prey availability and theneed to avoid predation.

Predispersal home range shift of an ocelot Leopardus pardalis (Carnivora: Felidae) on Barro Colorado Island, Panama

MeSH headings : Animal Migration / physiology; Animals; Felidae / classification; Felidae / physiology; Female; Male; Panama; Sexual Behavior, Animal / physiology; Sexual Maturation / physiology; Social Behavior; Telemetry
TL;DR: The timing of the shift, along with the subadult's increase in weight into the weight range of adult ocelots four months after establishing the new territory, suggests that predispersal home range shifts could act as a low risk and opportunistic strategy for reaching adult size, while minimizing competition with parents and siblings, in preparation for an eventual dispersal into a new breeding territory.

Journal of Mammalogy, 87(4), 808–816.

By: R. Moreno*, R. Kays* & R. Samudio*

author keywords: Barro Colorado Island; Carnivora; competitive release; diet; felid; predation
TL;DR: Both populations of ocelots in the study ate larger prey than elsewhere in their range, suggesting that their fundamental niche includes more medium-sized prey than their realized niche in other sites. (via Semantic Scholar)

DEVELOPMENTAL EFFECTS OF CLIMATE ON THE LION'S MANE (PANTHERA LEO)

Journal of Mammalogy, 87(2), 193–200.

By: B. Patterson*, R. Kays*, S. Kasiki* & V. Sebestyen*

author keywords: developmental effects; lion; mane; Panthera leo; phenotypic plasticity; sexual selection; temperature
TL;DR: Study of captive lions housed comparably across 12 degrees of latitude in North America correlated mane variation with climatic, life-history, and husbandry variables and found mane length and density were inversely correlated with temperature; color variation was unrelated.

Livestock predation by lions (Panthera leo) and other carnivores on ranches neighboring Tsavo National ParkS, Kenya

Biological Conservation, 119(4), 507–516.

By: B. Patterson*, S. Kasiki*, E. Selempo & R. Kays*

author keywords: lion; predator; conflict; cattle; Kenya; seasonality
TL;DR: Intensified predation in the wet season differs from patterns of lion predation elsewhere but reinforces the pattern that large carnivores take more livestock when native prey are most difficult to find and kill. (via Semantic Scholar)

A Survey of the Parasites of Coyotes (Canis latrans) in New York based on Fecal Analysis

Journal of Wildlife Diseases, 39(3), 712–717.

By: M. Gompper*, R. Goodman*, R. Kays*, J. Ray*, C. Fiorello* & S. Wade*

author keywords: Canis latrans; coyotes; parasites; New York; survey

TL;DR: Parasite component community diversity was higher than in middle and northern sites and infracommunity species richness was greater in southern New York than at the other sites, which may reflect the variable diets of coyotes, as well as recent colonization of the region and the mixing of component communities from expanding coyote populations.

The social organization of the kinkajou Potos flavus (Procyonidae)

Journal of Zoology, 253(4), 491–504.

By: R. Kays* & J. Gittleman*

author keywords: behaviour; carnivores; kinkajou; Potos flavus; primate evolution; social organization
TL;DR: Although the composition of social groups was polyandrous, males also copulated with non-group females which suggests a promiscuous mating system, and female-biased dispersal and patterns of male association seem to be patrilineal and based on resource defence. (via Semantic Scholar)

MeSH headings : Age Factors; Animals; Behavior, Animal / physiology; Female; Genetics, Population; Heterozygote; Likelihood Functions; Lorisidae / physiology; Male; Microsatellite Repeats
TL;DR: Copulation asymmetry in kinkajou social groups does not necessarily reflect cooperation due to kinship ties between the two adult males within a group as one of two adult male pairs sampled was unrelated. (via Semantic Scholar)
