Utilisation of the African Elephant [PDF]

Nature, 1878
I have just read some remarks in NATURE (vol. xix. p. 54) on the utilisation of the African elephant, which I think are worth considering. Judging from the specimens in the Regent's Park Gardens, which I suppose have not been selected in any way, and are therefore only average samples of the African species, I should say that the African elephant would

The impact of zoo education programmes on connection to nature considering programme type, participants' demographics and their initial connection

People and Nature, EarlyView.
Abstract Participants in environmental education programmes can have different preexisting attitudes and experiences that could influence the educational outcomes. The present study focuses on zoo education and its goal of connecting people to nature.

Mitochondrial DNA analysis of two southern African elephant populations

Koedoe: African Protected Area Conservation and Science, 1996
The modern view is that there are at most only two valid forms of the African elephant namely Loxodonta qfricana africana, the bush elephant, and L.a. cyclotis, the forest elephant (Ansell 1974; Meester et al. 1986).

The potential effect of megafaunal extinctions on modern conservation of horse chestnut Aesculus hippocastanum

PLANTS, PEOPLE, PLANET, EarlyView.
Many plant species worldwide are struggling to regenerate due to the ongoing effects of climate change. These effects appear to be further exacerbated by the loss of keystone megafauna, which were important seed dispersers. By identifying the traits commonly seen in seeds spread by modern elephants, it is possible to predict which species likely ...

Tracking Wintertime Behaviour of Emperor Penguins Using High‐Resolution Synthetic Aperture Radar Imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using 25–30 cm Umbra synthetic aperture radar (SAR) imagery combined with ground validation of our observations, we introduce a method to track the phenology of emperor penguins during the Antarctic winter. We successfully identified events in the breeding cycle, which were previously impossible to observe during the complete darkness of Antarctic ...

The elephant brain in numbers

Frontiers in Neuroanatomy, 2014
What explains the superior cognitive abilities of the human brain compared to other, larger brains? Here we investigate the possibility that the human brain has a larger number of neurons than even larger brains by determining the cellular composition of

The African Elephant Database

Pachyderm, 1993
Outlines the background and development of the African Elephant Database and notes aspects associated with variation in data quality. Suggests that the variability if data quality does not negate the value of the database in population monitoring nor in its use in trend analysis and notes that it is important the AfESG work towards making the data ...

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

Wildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)
