Spring spotlight counts provide reliable indices to track changes in population size of mountain-dwelling red deer Cervus elaphus

Wildlife Biology, 2016
Monitoring changes in animal abundance is a central issue in conservation biology. Population indices may be a valuable support to wildlife managers in coarse-scale survey programs, as they normally represent more intuitive and less expensive monitoring ...

A preliminary note on the visual changes in femur marrow fat as an indicator of femur fat percentage of springbok Antidorcas Marsupialis and blesbok Damaliscus Dorcas Phillipsi

Koedoe: African Protected Area Conservation and Science, 1973
Changes occuring in marrow fat reserves of animals have been used as an indicator of their physical condition (Cheatum, 1949; Riney, 1955). Cheatum correlated his visual estimate with a chemical analysis and Riney used four different condition classes ...

Peptide Biomarkers Discovery for Seven Species of Deer Antler Using LC-MS/MS and Label-Free Approach

Molecules, 2022
Deer antler is a globally widely used precious natural medicine and the material of deer horn gelatin. However, identification of deer antler species based on traditional approaches are problematic because of their similarity in appearance and physical ...

Experimental Assessment of the Effects of Substrate Choice on the Duration of Chemical Signals in Fecal Scent‐Marks of Free‐Ranging Iberian Wolves

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Chemical communication, typically based on feces, urine, and glandular secretions, often deposited as substrate scent marks, plays a key role in social organization and communication among many mammals, especially carnivores. This study assesses experimentally whether the type of substrate chosen for fecal deposition and the temperature ...

Mitochondrial PCGs Provide Novel Insights into Subspecies Classification, Codon Usage and Selection of Cervus canadensis Distributed in Qinghai and Gansu, China

Animals
Although Cervus elaphus (Linnaeus, 1758) has been well studied, the subspecific taxonomy of Cervus canadensis populations in Qinghai and Gansu, China, is still controversial, and the mitochondrial characteristics of Cervus elaphus (Linnaeus, 1758) remain

Vegetation map and assessment of naturalness degree of the Ogliastra territory (Sardinia, Italy)

Forest@, 2012
A cartographic representation of the vegetation characteristics over a large area of the Ogliastra territory, coupled with the use of several environmental indexes, allowed to estimate the degree of naturalness of this area.

Occurrence of Crocuta (Carnivora, Hyaenidae) from a potential Middle Pleistocene site at Pirro Nord (Apricena, southern Italy)

Journal of Quaternary Science, EarlyView.
ABSTRACT The Pirro Nord quarry has yielded evidence of one of the earliest hominin presences in western Europe, accompanied by an extremely rich and diverse collection of vertebrate remains, including amphibians, reptiles, birds, and small and large mammals.

Environmental and temporal factors affecting record white‐tailed deer antler characteristics in Ontario, Canada

The Journal of Wildlife Management, EarlyView.
Antler characteristics are influenced by a combination of genetics, age, and environmental factors, notably habitat quality and resource availability. In this study, we explored how diverse environmental factors, including climate and land cover composition, affect antler size, tine configuration, and the distribution of record‐scoring white‐tailed ...

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

Oikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.
