Arboreal ants use a variety of plant structures as nesting sites, but may also nest in structures created by arboreal ecosystem engineers. We observed, for the first time, ants using empty cocoons of the economically ...

Surprisingly little attention has been paid to variation among countries in contributions
to conservation. As a first step, we developed a Megafauna Conservation Index (MCI)
that assesses the spatial, ecological and ...

Previous studies of African mole-rats of the genera Heliophobius and Fukomys (Bathyergidae)
in the regions of East and south central Africa have revealed a diversity of
species and vicariant populations, with patterns ...

Why is biological diversity distributed in the way that it is?
This question has been central to ecology and biogeography for centuries
and is of great importance for pure and applied reasons. I use a
functional trait ...

The global shipping network facilitates the transportation and introduction of marine and terrestrial
organisms to regions where they are not native, and some of these organisms
become invasive. South Africa was used as ...

Quantifying the drivers of biodiversity variation is a key topic in contemporary ecology. While the geographic distribution of biodiversity is broadly determined by water and energy, local environmental conditions may be ...

The peninsula effect predicts that the number of species should decline from the base of a
peninsula to the tip. However, evidence for the peninsula effect is ambiguous, as different
analytical methods, study taxa, and ...

Climate change has the potential to trigger social change. As a first
step towards understanding mechanisms determining the vulnerability
of animal societies to rising temperatures, we investigated interactions
Garai, Marion Elizabeth(University of Pretoria, 1997)
Groups of translocated orphaned juvenile African elephants were studied in holding pens and
following their release to assess how they re-organize and restructure socially by adopting roles,
and if they show behavioural ...

Antarctica, the sub-Antarctic islands and surrounding Southern Ocean are regarded as one of the planet’s
last remaining wildernesses, ‘insulated from threat by [their] remoteness and protection under the Antarctic
BACKGROUND : A substantial period of life after reproduction ends, known as postreproductive lifespan (PRLS), is
at odds with classical life history theory and its causes and mechanisms have puzzled evolutionary biologists ...
Van der Merwe, Ingrid; Oosthuizen, Maria Kathleen; Ganswindt, Andre; Bennett, Nigel C., 1961-; Haim, Abraham(Company of Biologists, 2017)
Effects of photophase illuminance (1, 10, 100 and 330 lx of white
incandescent lighting) on daily rhythms of locomotor activity, urine
production and 6-sulfatoxymelatonin (6-SMT; 10 versus 330 lx) were
studied in nocturnal ...
The Antarctic Pack Ice Seal (APIS) Program
was initiated in 1994 to estimate the abundance of four
species of Antarctic phocids: the crabeater seal Lobodon

The western honeybee, Apis mellifera is a prominent model organism in the field of sociogenomics
and a recent upgrade substantially improved annotations of the reference genome.
Nevertheless, genome assemblies based on ...

Savannas once constituted the range of many species that human encroachment has now reduced to a fraction of their former distribution. Many survive only in protected areas. Poaching reduces the savanna elephant, even where ...

Daylight fluorescent pigment powders are frequently used to self-mark tephritid flies that
are released in sterile insect technique programmes and for studies on their population
ecology, movement and behaviour. This ...

The cytotoxicity of the venom of 25 species of Old World elapid snake was tested
and compared with the morphological and behavioural adaptations of hooding and spitting. We determined that, contrary to previous assumptions, ...
