The Effect Of Environmental Variability On The Foraging Behaviour Of Plains Zebra (Equus quagga) In The Makgadikgadi, Botswana

The-effect-of-environmental-variability-on-the-foraging-behaviour-of-plains-zebra

At least 5 million species of plants and animals share the planet earth (Vié, Hilton-Taylor & Stuart 2009) and, in 2011, the human population passed 7 billion, increasing the pressure on every other species. The requirements of wildlife populations for land and resources overlap with those of human populations, thereby leading to human/wildlife conflict (Lamarque et al. 2008). Indeed, advances …

Key Factors And Related Principles In The Conservation Of Large African Carnivores

Key Factors And Related Principles In The Conservation Of Large African Carnivores

Despite conservation efforts, large carnivore numbers continue to decline globally (Anonymous 2010a). Significant failures have occurred, notably, the extinction of three tiger Panthera tigris subspecies within the past 50 years (Weber & Rabinowitz 1996). The large African carnivore guild is made up of seven species (Dalerum et al. 2008) with declining populations, which are classed as follows by the International …

Characterising Ontogenetic Niche Shifts In Nile Crocodile

Characterising-ontogenetic-niche-shifts-in-Nile-crocodile

Nile crocodiles undergo a three to five order of magnitude increase in body size during their lifespan. This shift coincides with a change in resource and habitat use which influences the strength, type and symmetry of interactions with other species. Identifying size-specific crocodile groups displaying similar traits is important for conservation planning. Here, we illustrate how stable carbon (δ13C) and …

Diet of the Nile Crocodile (Crocodylus niloticus) in the Okavango Delta, Botswana

Diet Of The Nile Crocodile in Okavango Botswana

Although difficult to compare statistically (because of seasons, size classes, and types of analyses used), the ontogenetic trends of crocodilian diet are similar for the different species. Young crocodilians primarily consume insects and arachnids (Platt et al., 2002); these decrease in importance as crocodilians increase in size (Tucker et al., 1996). The intermediate size classes of crocodilians have the most …
