Home ranges, habitat and body mass: simple correlates of home range size in ungulates.
The spatial scale of animal space use, e.g. measured as individual home range size, is a key trait with important implications for ecological and evolutionary processes as well as management and conservation of populations and ecosystems. Explaining variation in home range size has therefore received great attention in ecological research. However, few studies have examined multiple hypotheses ...
متن کاملDoes body condition affect immediate post-capture survival of ungulates?
Many factors are known or are thought to increase vulnerability to capture-related mortality in ungulates. I compared body condition of Rocky Mountain elk (Cervus elaphus nelson), mule deer (Odocoileus hemionus), and pronghorn (Antilocapra americana) to assess whether those that survived capture differed from those that did not. Fate of ungulates was generally not related to condition (F1,646 =...
متن کاملDiets of savanna ungulates from stable carbon isotope composition of faeces
Hypotheses to explain diversity among African ungulates focus largely on niche separation along a browser/grazer continuum. However, a number of studies advocate that the browser/grazer distinction insufficiently describes the full extent of dietary variation that occurs within and between taxa. Disparate classification schemes exist because of a lack of uniform and reliable data for many taxa,...
متن کاملAnalysing the isotopic life history of the alpine ungulates Capra ibex and Rupicapra rupicapra rupicapra through their horns.
The horn of ungulate grazers offers a valuable isotopic record of their diet and environment. However, there have been no reports of the spatio-temporal variation of the isotopic composition of horns. We investigated patterns of carbon (delta(13)C) and nitrogen (delta(15)N) isotopic composition along and perpendicular to the horn axis in Capra ibex and Rupicapra rupicapra rupicapra to assess th...
متن کاملAlpine flora of Hezar mountain (SE Iran)
Iran is a mountainous country. Hezar Mt., is an isolated mountain with the highest peak of 4465 m (above sea level) located in southeast of Iran. This paper aims to provide a general overview of alpine phytodiversity of Hezar Mt. Alpine regions are above timber-line which is dependent on the climate, slopes and human activities. The timberline at Hezar Mt., is varying from 3200 m (North slope) ...
