A Novel Objective Method of Estimating the Age of Mandibles from African Elephants (Loxodonta africana Africana). [PDF]

PLoS ONE, 2015
The importance of assigning an accurate estimate of age and sex to elephant carcasses found in the wild has increased in recent years with the escalation in levels of poaching throughout Africa.

Behavioural variability among captive African elephants in the use of the trunk while feeding [PDF]

PeerJ, 2020
The Proboscideans, an order of mammals including elephants, are the largest of the Earth lands animals. One probable consequence of the rapid increase of their body size is the development of the trunk, a multitask highly sensitive organ used in a large ...

How wildlife respond to tropical cyclones: short‐term tactics and long‐term impacts

Biological Reviews, EarlyView.
ABSTRACT From butterflies to lizards and from sharks to seabirds, wildlife exhibit tactics to survive the impacts of tropical cyclones, also known as hurricanes, cyclones, or typhoons depending on where they occur. Some species seek refuge during the storm by moving, some remain in place and ride it out, and others move longer distances, avoiding the ...

Plasma testosterone levels in relation to musth in the male African Elephant

Koedoe: African Protected Area Conservation and Science, 1984
A long-term study of the behaviour and ecology of the African elephant Loxodonta africana was begun in the Addo Elephant National Park in 1976. During the period June 1976 to March 1979 regular observations were made on all animals.

Estimating exposed pulp lengths of tusks in the African elephant (Loxodonta africana africana) : article

Journal of the South African Veterinary Association, 2008
Captive and wild African elephants frequently suffer tusk fractures. Several institutions shorten the tusks of captive elephants to reduce fractures and injury as a result of behaviour within enclosures. Fracturing or coronal amputations that expose pulp lead to pain for the elephant.

The evidence base for ranger patrol effectiveness in conservation and how to improve it

Biological Reviews, EarlyView.
ABSTRACT Ranger patrols are a cornerstone of wildlife protection efforts around the world and occur across all ecological governance systems. Evidence that patrols reduce threats to wildlife and enable their recovery has not been systematically examined previously.

Enduring consequences of early experiences: 40 year effects on survival and success among African elephants (Loxodonta africana)

, 2013
Growth from conception to reproductive onset in African elephants (Loxodonta africana) provides insights into phenotypic plasticity, individual adaptive plastic responses and facultative maternal investment.

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, EarlyView.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Investigation of the effect of poaching on African elephant (Loxodonta africana) group size and composition in Ruaha National Park, Tanzania [PDF]

, 2020
Monitoring the impacts of poaching on wildlife is crucial to the management of ecosystems and wildlife populations. Previous studies have shown that poaching can affect the demography, reproduction and behavior of wildlife.

Response of African elephants (Loxodonta africana) to seasonal changes in rainfall. [PDF]

PLoS ONE, 2014
The factors that trigger sudden, seasonal movements of elephants are uncertain. We hypothesized that savannah elephant movements at the end of the dry season may be a response to their detection of distant thunderstorms.
