Seasonal Home Ranges Of Non-Migratory Zebra In The Central And Peripheral Okavango Delta

Seasonal-home-ranges-of-non-migratory-zebra

The availability and quality of preferred forage changes seasonally (East, 1984), as does the availability of palatable water (Redfern, 2003). It could therefore be expected that herbivores may alter their ranges seasonally, ensuring that they can access the best forage as it becomes available. In the most extreme situations this can lead to a migratory existence (Fryxell, 1987), as discussed …

Eco Evolution Land Use By Zebras

eco-evolution-land-use-by-zebras

Most large-bodied wildlife populations in sub-Saharan Africa only survive in spatially contained protected regions (Newmark 1996). However, many are still declining because external changes influence ecological processes within conservation areas, leading to a lack of functionality (Western et al. 2009; Fynn and Bonyongo 2010). Wetland ecosystems are particularly vulnerable to external land use changes (Turner et al. 2000). The Okavango …

A Case Study Of A Zebra (Equus Burchelli) Migration In Botswana

A Case Study Of A Zebra (Equus Burchelli) Migration In Botswana

Historically, migrations or long-distance seasonal movements were common in a wide range of marine, freshwater and terrestrial taxa (Berger, 2004). Terrestrial mammal migrations, defined by Berger (2004) as ‘seasonal movements between discrete areas that are not used at other times of the year’, used to occur in most grassland and boreal forest ecosystems in Africa, Asia, Europe and North America …

Functional Conservation Areas And The Future Of Africa’s Wildlife

Functional-conservation-areas-and-the-future-of-Africas-wildlife

Many of Africa’s conservation areas (CAs) are experiencing large declines in the size and diversity of their ungulate populations (Whyte & Joubert, 1988; Ben-Shahar, 1993; Williamson, 2002; Owen-Smith & Mills, 2006; Caro & Scholte, 2007; Bolger et al., 2008; Newmark, 2008; Harris et al., 2009; Ogutu et al., 2009; Western, Russell & Cuthill, 2009). We provide evidence from a wide …

Effects Of Restriction Of Wild Herbivore Movement On Woody And Herbaceous Vegetation In The Okavango Delta Botswana

Effects-of-restriction-of-wild-herbivore-movement

Wildlife movements and migrations are increasingly being disrupted due to ongoing fragmentation of African savannahs (Fynn & Bonyongo, 2011). Free-ranging herbivores that are not subject to restrictions of movement by fences and other human land-use effects generally do not degrade their habitats because their highly mobile foraging strategies continually deflect their foraging to new areas and resources (McNaughton, 1985; Fynn, …

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 …

Makgadikgadi Zebra Migration Research 2008-2012

Makgadikgadi Zebra Migration Research 2008-2012

This research was initiated as a follow-up study to the research of Dr Chris Brooks conducted between 2001 and 2005. The research examined the foraging behaviour, spatial distribution and adaptability to environmental changes of plains zebra (Equus quagga) in the Makgadikgadi, Botswana, following the construction of an electrified fence in 2004. Seasonal changes in resource availability were documented and GPS …
