Evaluating expert-based habitat suitability information of terrestrial mammals with GPS-tracking data

Aim: Macroecological studies that require habitat suitability data for many species often derive this information from expert opinion. However, expert-based information is inherently subjective and thus prone to errors. The increasing availability of GPS tracking data offers opportunities to evaluate and supplement expert-based information with detailed empirical evidence. Here, we compared expert-based habitat suitability information from the International Union for Conservation of Nature (IUCN) with habitat suitability information derived from GPS-tracking data of 1,498 individuals from 49 mammal species.

Mammal Species Richness at a Catena and Nearby Waterholes during a Drought, Kruger National Park, South Africa

Catenas are undulating hillslopes on a granite geology characterised by different soil types that create an environmental gradient from crest to bottom. The main aim was to determine mammal species (>mongoose) present on one catenal slope and its waterholes and group them by feeding guild and body size. Species richness was highest at waterholes (21 species), followed by midslope (19) and sodic patch (16) on the catena. Small differences observed in species presence between zones and waterholes and between survey

Delayed effects of fire on habitat use by large herbivores in Acacia drepanolobium savanna

Fire is frequently used as a wildlife management tool in savanna habitats (Trollope, 1982). Burning stimulates sprouting of plants (Vesey-Fitzgerald, 1971), improving forage quality (Komarek, 1967; Dorgeloh, 1999). Several studies have supported quantitatively what has been well known by managers for some time, namely that ungulates are attracted by resprouting vegetation in recently burned areas (Moe, Wegge & Kapela, 1990; Wilsey, 1996; Tomor & Owen-Smith 2002). Rapid resprouting initiated by fire, and reinforced by herbivory (cf. McNaughton, 1985), may contribute

Factors affecting habitat use by Masai Giraffe (Giraffa camelopardalis tippelskirchi L) in Athi-Kapiti Plains ecosystem, Kenya

Increased human settlement, land use changes, loss of migration corridors, habitat loss and fragmentation have affected habitat use by Masai giraffe in Athi-Kapiti plains ecosystem. The purpose of the study was to assess the factors affecting habitat use by Masai giraffe (Giraffa camelopardalis tippelskirchi) in the Athi-Kapiti plains ecosystem and to generate information for giraffe sustainable conservation and management. The specific objectives of the study were to assess past and present giraffe population, assess the relative abundance of giraffe food
