Habituation to Auditory Stimuli by Captive African Elephants (Loxodonta Africana)
… conducted using four female African elephants (Loxodonta africana) at the Nashville Zoo. Elephants received each stimulus for a 10-day period. On the first sound presentation, the elephants reacted by exhibiting distress, avoidance, and vigilance behaviors. Over repeated presentations, the …

Chemosensory Behavior and Development of African Male Elephants (Loxodonta Africana)
African elephants are a polygynous species that raise offspring in a matriarchal society. Males disperse, spend time in male groups, and search for mates when mature. Urinary chemical signals play an important role in detecting reproductively active females. African male elephants develop movement, …

Chemical Signaling and Resource Use by African Elephants (Loxodonta Africana)
… dimorphic species like the African elephant, Loxodonta africana, resource distribution influences female dispersion, while the location of females shapes male dispersion. Human constriction of viable habitat has affected elephant movements and impact. Elephants travel in matriarchal family …

Waterhole Dynamics and Chemical Signals of African Elephants (<i> Loxodonta Africana </i>)
… dominate species, such as the African elephant (Loxodonta africana), may influence this aggregation. I examined the influence of wet and dry seasons and ambient temperature on the use of a waterhole by elephants as well as the co-occurrence of elephants and other mammals at the waterhole. …

Sexually Dimorphic Developmental Patterns of Chemosensory Behaviors in African Elephants (Loxodonta Africana)
Like many polygynous mammals, African elephants exhibit social dimorphism in which females reside in matriarchal groups while males often travel alone or in bachelor groups. Males search for receptive mates who may advertise their condition through chemical and other signals. The difference in …

Characterizing African Elephant (<i>Loxodonta Africana</i>) Population Dynamics and Distribution in Botswana
The African elephant (Loxodonta africana) is an iconic species that is globally threatened. Of the total continental population, 37% is found in Botswana, the highest number and density of elephants in Africa. Elephant management in this country remains challenging and complex as the population …

Patterns of Chemosensory Behavior in a Closed Population of Wild African Elephants (Loxodonta Africana)
<p>Chemosensory behaviors are used by many mammalian species to assess chemical signals in the environment. These chemical signals may contain important information about reproductive state, identity, status, or location of conspecifics. Elephants are a long-lived species and males reproduce at a …

Wire Netting Reduces African Elephant (<i>LOXODONTA AFRICANA</i>) Impact to Selected Large Trees in South Africa
<p>African elephants (<em>Loxodonta africana</em>) are ecosystem engineers in that they substantially alter the environment through their unique foraging and feeding habits. At high densities, elephants potentially have negative impacts on the environment, specifically to large trees. Because of …

Local ecological knowledge on the population dynamics of elephants (Loxodonta africana) in the Highlands of Northwest Namibia
There is a small population of elephants (Loxodonta africana) in the mountainous, remote area of northwest Namibia that is locally referred to as the Northern Highlands. The objective of this Research Project was to build a knowledge base on the population, behaviour and movements of elephants in …

An isotope comparison of elephant (Loxodonta africana) diets in the Kruger National Park and Welgevonden Game Reserve
The diet of African elephants (Loxodonta africana (Blumenbach, 1797)) living in savanna environments is unresolved. Elephants are known to include varying proportions of grass and browse into their diet, but there is uncertainty as to whether they are primarily grazers or browsers. This has …

Effect of Lion Calls on African Elephants (<i>Loxodonta Africana</i>) in Addo Elephant National Park, South Africa
… resources. Generally, African elephants (<em>Loxodonta africana</em>) experience little predation pressure; however, the risk of predation by lions (<em>Panthera leo</em>) increases other prey species are less abundant. In elephant herds, related females and their offspring travel together in …

Control of testosterone secretion, musth and aggressive behaviour in African elephant (Loxodonta Africana) bulls using a GnRH vaccine
Aggressive behaviour with or without musth can constitute a serious management problem for captive and free-ranging African elephant bulls, and can endanger the lives of both animals and man where such elephants are kept. Generally, bulls in musth have to be restrained to such an extent that it …

Effect of Matriarchs on Group Interactions, Kinship Fitness, and Differences In Chemosensory Behavior of African Elephants (Loxodonta Africana)
Female African elephants exhibit multiple levels of social organization with the family as the functional social unit. Families consist of related females and the oldest female is the matriarch. Related family groups that frequently fuse are termed kinship groups, led by the grand matriarch. I …

Annals of ivory : perspectives on African elephant Loxodonta africana (Blumenbach 1797) feeding ecology from a multi-decadal record.
… the dietary responses of African elephants (Loxodonta africana) to environmental change by testing the hypothesis that diet switching (from predominantly browse-based to more grass-rich diets) is driven by cyclical patterns of climate and habitat change in a southern African savanna. …

African savanna elephant (Loxodonta africana) impacts on vegetation in a fenced area and the broader implications for elephant conservation.
… population of African savanna elephants (Loxodonta africana) impacted tree species in the small, fenced Karongwe Private Game Reserve (KPGR), South Africa and to determine levels of tree recovery. Trees in high-use areas were significantly less likely to show signs of debarking and push …

The Examination of Enrichment Using Space and Food for African Elephants (Loxodonta Africana) at the San Diego Zoo Safari Park
<p>Concern for elephant welfare in zoological facilities has prompted a number of exhibit and management modifications, including those involving enrichment. Knowledge of how these changes impact measures of health and wellbeing, such as elephant movement and behavior, is crucial as the effects of …

The Relationship of Herpetofaunal Community Composition to an Elephant (Loxodonta Africana) Modified Savanna Woodland of Northern Tanzania, and Bioassays with African Elephants
Herpetofauna diversity and richness were compared in areas that varied in the degree of elephant impact on the woody vegetation (Acacia spp.). The study was conducted at Ndarakwai Ranch in northeastern Tanzania. Elephants moving between three National Parks in Kenya and Tanzania visit this …

Habitat use, feeding ecology and the impact of re-introduced elephants (Loxodonta africana) on trees within a restricted conservation area in the semi-arid, Little Karoo, South Africa
The reintroduction of free-roaming elephants on the 540 km2 Sanbona Wildlife Reserve in the Little Karoo, Western Cape, South Africa, raised concerns over the possible negative impacts that these animals may have on the biodiversity of the property, especially the tree component. The main …

An Assessment of Perceived Crop Damage in a Tanzanian Village Impacted by Human-Elephant Conflict and an Investigation of Deterrent Properties of African Elephant (Loxodonta Africana) Exudates Using Bioassays
… being converted to farmland. African elephants (Loxodonta africana) will raid agricultural fields to feed on crops, and many agriculturalists attribute the majority of their crop damage to elephants. The first two objectives of this study were to evaluate the accuracy of this perception by …
