Aim We explored morphological and ecophysiological traits that enable invasive
Australian acacias to compete with native species for resources (light, water and
nutrients) necessary to support the substantial growth ...

Although interspecific body size frequency distributions are well documented for many taxa, including the insects, intraspecific body size frequency distributions (IaBSFDs) are more poorly known, and their variation among ...

Previous studies in the fynbos biome of the
Western Cape, South Africa, have suggested that biological decomposition rates in the fynbos vegetation type, on poor soils, may be so low that fire is the main factor contributing ...

The circadian rhythm of locomotor activity in a southern African shrew, the reddish-grey musk shrew Crocidura cyanea was investigated. Thirteen individuals were subjected to three successive light cycles, each cycle lasting ...
Bothrometopus huntleyi is a flightless weevil endemic to the volcanically-formed sub-Antarctic Prince Edward Islands archipelago that arose approximately 0.5 million years ago (m.y.a.). Since emergence, a series of volcanic ...
Background: South Africa’s long and extensive trade activity has ensured ample opportunities for exotic species introduction. Whereas the rich biodiversity of endemic southern African fauna has been the focus of many ...
Dispersal can strongly affect the spatiotemporal dynamics of a species (its spread, spatial distribution
and persistence). We investigated how two dispersal behaviours, namely prey evasion (PE) and predator
pursuit (PP), ...
Although pathogens and predators have been widely used as bio-control agents against problematic prey
species, little has been done to examine the prevalence and aggregation of pathogens in spatially structured
eco-epidemiological ...
Aim Species’ native ranges reflect the net outcome of interactions between lifehistory
strategies and biotic and abiotic influences over evolutionary time-scales.
Differences in native ranges might be indicative both of ...
Aim To assess associations between invasiveness, genome size and species traits in
Australian Acacia species introduced outside their native range.
Location Global.
Methods Holoploid genome size was determined by flow ...

1. Monitoring the abundance and spatial structure of invasive alien plant populations is important
for designing and measuring the efficacy of long-term management strategies. However, methods
for monitoring over large ...
Because invasive species threaten the integrity of natural ecosystems,
a major goal in ecology is to develop predictive models to
determine which species may become widespread and where they
may invade. Indeed, considerable ...
Forecasting the temporal trend of a focal species, its range expansion or retraction, provides crucial
information regarding population viability. To this end, we require the accumulation of temporal records
which is ...

We asked whether the occurrence and the extent of host gender-biased parasitism vary among higher parasite taxa, among
individual species within these taxa and within parasite species among localities. To answer this ...
