Changes in African Elephant (Loxodonta africana) faecal steroid concentrations post-defaecation

Bothalia: African Biodiversity & Conservation, 2018
Background: Faecal hormone metabolite measurement is a widely used tool for monitoring reproductive function and response to stressors in wildlife. Despite many advantages of this technique, the delay between defaecation, sample collection and processing

Livestock grazing and geodiversity modulate wild herbivore distributions in an African community conservation area

Wildlife Biology, EarlyView.
The rapid decline of African wildlife populations demands immediate action to mitigate further losses and restore ecosystems. A key factor influencing wildlife distribution is the relationship between the energetic needs of species and the availability of forage, both in terms of quality and quantity.

Intestinal Protozoa of the African ElephantLoxodonta Africana(Blumenbach) [PDF]

South African Journal of Zoology, 1980
The digestive tract of 15 elephants from South Africa and two from Zaïre were sampled in order to determine the identity, density and population composition of the intestinal protozoa. The following orders were represented: Gymnostomatida, Trichostomatida and Entodiniomorphida. Altogether 17 species were identified, of which three are new.

The Greatest Show (Birds) on Earth: Public Presentations and Their Welfare Impacts on Zoo‐Housed Birds

Zoo Biology, EarlyView.
Birds involved in bird shows were compared against non‐show birds regarding show paticipation, behaviour, body score condiiton, and feather condition. Additionally, comparisons between on and off show days as well as before and after the show were made to investigate differences in behaviour and condition. Show birds demonstrated a closer to ideal body

Sources of Eustress in Captivity

Zoo Biology, EarlyView.
Zoo environments foster enhanced animal welfare, integrated conservation, and improved population sustainability through the provision of eustressful factors (e.g., enrichment, social choice, positive human‐animal relationships), thus promoting cognitive challenge, improved resilience, and positive life experiences.

Contrasting properties of predation and scavenging networks governed by megaherbivores in an African savannah

Journal of Animal Ecology, EarlyView.
For the first time, predation and scavenging networks are directly compared within a single ecosystem. Using an 8‐year dataset of African mammals, including megaherbivores, this study reveals distinct structural rules and body mass constraints, providing a scalable framework for studying consumer–resource dynamics and ecosystem function.

Ranging of older male elephants introduced to an existing small population without older males: Pilanesberg National Park

Koedoe: African Protected Area Conservation and Science, 2004
The African elephant Loxodonta africana is one of the key components of African savanna. Not only do they play a crucial role in the ecosystem (Dublin et al. 1990; Van de Vijver et al. 1999), but they also provide one of the integral parts of sustainable

Temporal Responses to Warming: Do Wild Herbivores Trade Off Heat, Predators, and Humans?

Integrative Zoology, EarlyView.
We untangled how summer temperature, predators, and humans influenced behavioral responses in two deer species. Both reduced their daily activity level in response to warming, yet only roe deer increased nocturnality to avoid heat. Conversely, fallow deer traded off heat avoidance with predator avoidance.

The Relationships Between Rodent Control Efforts, Abundance, Damage, and Outcomes

Integrative Zoology, EarlyView.
Diminishing returns on investment are a common pattern in agricultural and biodiversity conservation studies. A review shows few such studies of the effort‐outcomes relationship for rodent control efforts. It is recommended that future rodent control studies estimate such effort‐outcome relationships. ABSTRACT Rodents cause damage to agricultural crops
