Common Eland
Tragelaphus oryx – Common Eland recognised, though their validity has been in dispute (Thouless 2013): Tragelaphus o. livingstonii (Sclater 1864; Livingstone's Eland): also called kaufmanni, niediecki, selousi and triangularis. It is found in the Central Zambezian Miombo woodlands i.e. south- central Africa (Angola, Zambia, Democratic Republic of the Congo, Zimbabwe, Mozambique and Malawi). Livingstone's Eland has a brown pelt with up to twelve stripes. Tragelaphus o. oryx (Pallas 1766; Cape Eland): also called alces, barbatus, canna and oreas. This subspecies is found south of the Zambezi river (South Africa, Botswana and Namibia). The fur is tawny, and adults lose their stripes. Regional Red List status (2016) Least Concern Tragelaphus o. pattersonianus (Lydekker 1906; East National Red List status (2004) Least Concern African Eland or Patterson's Eland): also called Reasons for change No change billingae. It is found in east Africa extending into the Somali arid areas, hence its common name. Its coat Global Red List status (2008) Least concern can have up to 12 stripes. TOPS listing (NEMBA) None Tragelaphus o. oryx occurs throughout the larger part of South Africa, but the far northern Limpopo Province CITES listing None bordering Zimbabwe is regarded as a transitional zone Endemic No between T. o. oryx and T. o. livingstonii or an area where they overlap. This argues the case that they should rather During drought conditions Eland roam extensively be described as ecotypes (in ecotypes, it is common for in order to meet forage and water requirements; in continuous, gradual geographic variation to impose the southern Kalahari during abnormally dry analogous phenotypic and/or genetic variation; this conditions, Eland were found to cover more than situation is called cline.). -
Mammal Species Richness at a Catena and Nearby Waterholes During a Drought, Kruger National Park, South Africa
diversity Article Mammal Species Richness at a Catena and Nearby Waterholes during a Drought, Kruger National Park, South Africa Beanélri B. Janecke Animal, Wildlife & Grassland Sciences, University of the Free State, 205 Nelson Mandela Road, Park West, Bloemfontein 9301, South Africa; [email protected]; Tel.: +27-51-401-9030 Abstract: 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 periods were not significant (p = 0.5267 and p = 0.9139). In total, 33 species were observed with camera traps: 18 herbivore species, 10 carnivores, two insectivores and three omnivores. Eight small mammal species, two dwarf antelopes, 11 medium, six large and six mega-sized mammals were observed. Some species might not have been recorded because of drought, seasonal movement or because they travelled outside the view of cameras. Mammal presence is determined by food availability and accessibility, space, competition, distance to water, habitat preferences, predators, body size, social behaviour, bound to territories, etc. The variety in body size and feeding guilds possibly indicates a functioning catenal ecosystem. This knowledge can be beneficial in monitoring and conservation of species in the park.

Insular Energetics and Trophic Structure Stability Glossary Bibliography Biographical Sketch Summary In ancient times, belief in spontaneous generation and divine creation dominated thinking about insular biotas. Weaknesses in these theories let to questioning of those ideas, first by clergy and later by scientists, culminating in Darwin's and Wallace's postulation of evolution through natural selection. MacArthur and Wilson presented a dynamic equilibrium model of insular ecology and biogeography that represented the number of species on an island as an equilibrium between immigration and extinction rates, as influenced by insular sizes and distances from mainlands. This model has been tested and found generally true but requiring minor modifications, such as accounting for disturbancesUNESCO affecting the equilibrium nu–mber. EOLSS There has been basic controversy as to whether insular biotas reflect deterministic or stochastic processes. It is likely that neither extreme SAMPLEis completely correct but rather CHAPTERS the two kinds of processes interact. -

Antelope (Includes Sables, Impalas, and Elands)
Antelope (includes Sables, Impalas, and Elands) Range: antelope species can be found in parts of Africa, Asia, and the Middle East Habitat: varies widely, from savanna to woodlands to marshes and swamps to desert, depending on the species It’s about horns and hooves Horns— All antelope species have horns, although in some species they are only found on the males. The horns are made of a bony core, encased in a hard material made largely of keratin. They are permanently attached—not like a deer’s antlers, which are shed each year. Some antelope horns, like those of the kudu Tragelaphus sp. and eland Taurotragus sp., twist in interesting spirals; others have ridges, like those of the impala Aephyceros melampus and the sable antelope Hippotragus niger; and others grow in wide curves with a sharp point on the end, like those of the wildebeest Connochaetes sp. (also called the gnu, a name it gets from its call, which sounds like “ge-nu”). Antelope use their horns in defense against predators; males and sometimes females also use them to establish their position in a herd or to fight rivals Hooves— Hooves are another specialty for many antelope. Each hoof has a split down the middle, dividing the hoof into two “toes.” Because they live in wetlands and swamps, sitatungas Tragelaphus spekeii have wide hooves up to 7 inches (18 centimeters) across that help them walk on mud and mats of plants without slipping. Nile lechwes Kobus magaceros, which also live in swampy areas, have long, pointed hooves to give them sure footing in the water. -

Assembly Rules for Functional Groups of North American Shrews: Effects of Geographic Range and Habitat Partitioning
OIKOS 107: 141Á/147, 2004 Assembly rules for functional groups of North American shrews: effects of geographic range and habitat partitioning Timothy S. McCay, Matthew J. Lovallo, W. Mark Ford and Michael A. Menzel McCay, T. S., Lovallo, M. J., Ford, W. M. and Menzel, M. A. 2004. Assembly rules for functional groups of North American shrews: effects of geographic range and habitat partitioning. Á/ Oikos 107: 141Á/147. We examined the representation of shrew species within assemblages at 197 sites in the southern Appalachian Mountains, USA. Assemblages were classified according to representation of functional groups, including fossorial, small epigeal, and large epigeal. Average (9/SD) species richness was 2.99/1.0 and assemblages averaged 0.8 species in the fossorial and large epigeal groups and 1.3 species in the small epigeal group. Compliance with Fox’s assembly rule was evaluated by dividing sites into those likely under the rule (favored) and those unlikely under the rule. The number of favored sites was compared to expected numbers of favored sites under three null models of community development, which variously incorporated observed characteristics of species in the regional pool. Number of favored sites (175 [89%]) exceeded the number found in each of 25,000 sets of assemblages simulated (PB/0.00004) using algorithms that incorporated the observed species richness of each site and the observed incidences of each species. However, the number of favored sites did not differ (P/0.1054) from the number expected when patterns of allopatry and sympatry were preserved in the null model. Thus, the tendency for the equitable representation of functional groups in shrew assemblages was primarily due to the pattern of allopatry among similar species, and we believe that the striking compliance of these sites with Fox’s assembly rule is largely due to structure within the regional species pool, rather than extant competitive interactions. -

The widely demonstrated presence of structural patterns in nature may imply the existence of rules that regulate the organization of ecological communities. In this review, I present a compilation of major assembly rules that fundament, in a great proportion, the community assembly theory. Initially, I present a general overview of key concepts underlying mechanisms in the structure of ecological communities. Subsequently, two major approaches or paradigms associated to the assembly of communities, in particular the origin of assembly rules, definition, the problem of scale and (i.e. species-based and trait-based) for the assembly of communities are discussed.
