Mark-recapture and mark-resight methods for estimating abundance with remote cameras: a carnivore case study. [PDF]

open access: yesPLoS ONE, 2015
Abundance estimation of carnivore populations is difficult and has prompted the use of non-invasive detection methods, such as remotely-triggered cameras, to collect data.

Objective measurement of Akodon budini dorsal coloration: methodological concerns

open access: yesAnais da Academia Brasileira de Ciências, 2016
The role of color in taxonomic and systematic studies of several taxa is central. Color data are more valuable if they permit comparisons. We aimed to provide pelage objective color measurements of a series of Akodon budini and to use those color data to

The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Extensive population genetic structure in the giraffe

open access: yesBMC Biology, 2007
Background A central question in the evolutionary diversification of large, widespread, mobile mammals is how substantial differentiation can arise, particularly in the absence of topographic or habitat barriers to dispersal. All extant giraffes (Giraffa

Differences in mammal community response to highway construction across different levels of human land use

open access: yesWildlife Biology, EarlyView.
Worldwide, transportation agencies have been involved in road mitigation efforts to reduce road mortality and promote connectivity of endangered species. Baseline data on how mammals respond to highway construction, however, are rarely collected in road mitigation and monitoring studies, including in the USA.

«Pepper's patches» on Rangifer pelage

open access: yesRangifer, 1986
We describe and give frequencies of occurrence of a rarely-mentioned pattern of spots in Rangifer pelage. We also show that the pattern was well-known to Palaeolithic humans who recorded it in their cave art.

Born to die: pack and population level estimates of wolf pup survival and recruitment in the Greater Voyageurs Ecosystem

open access: yesWildlife Biology, EarlyView.
Wolf pup Canis lupus survival is a key driver of wolf population dynamics that remains poorly understood, especially in forested systems, because wolf pups are difficult to monitor. We used a combination of pup counts at dens and remote camera observations to estimate annual survival and recruitment of wolf pups in the Greater Voyageurs Ecosystem, MN ...

Estimating large carnivore populations in an arid fenced reserve using spatial capture–recapture modelling

open access: yesWildlife Biology, EarlyView.
In fenced protected areas where large carnivore populations persist or have been restored through reintroduction, population monitoring is essential to inform management. Robust density estimates are particularly important given the strong influence of large carnivores on ecosystem processes, yet such data remain scarce for arid systems where ...

Evolution of Pelage Luminance in Squirrels (Sciuridae)

open access: yesFrontiers in Ecology and Evolution, 2020
Pelage luminance has been found in many mammalian systems to follow patterns predicted by Gloger’s rule where darker colored animals are associated with environments that are warmer and more moist.
