Born to kill: Predatory functional responses of the littoral amphipod Echinogammarus marinus Leach throughout its life history
Studies of predator–prey interactions, and in particular the derivation of functional responses, have typically focussed on adults or single life-history stages, with subsequent food web analyses often simply using average ...
Gas exchange patterns and water loss rates in the Table Mountain cockroach, Aptera fusca (Blattodea: Blaberidae)
(Company of Biologists, 2013)
The importance of metabolic rate and/or spiracle modulation for saving respiratory water is contentious. One major explanation for gas exchange pattern variation in terrestrial insects is to effect a respiratory water ...
The ecological integrity of the Lower Olifants River, Limpopo province, South Africa: 2009-2015-Part A: Olifants River main stem
(Taylor & Francis, 2017)
The major rivers of the South African ‘Lowveld’ (low-latitude savanna) suffer numerous impacts from upstream economic activities. Whereas monitoring these rivers is required to detect biodiversity losses, record ...
Managing consequences of climate-driven species redistribution requires intergration of ecology, conservation and social science
(Cambridge Philosophical Society, 2018)
Climate change is driving a pervasive global redistribution of the planet’s species. Species redistribution poses new questions for the study of ecosystems, conservation science and human societies that require a coordinated ...
Seed characteristics in Cacataceae: Useful diagnostic features for screening species for invasiveness?
(Elsevier B.V., 2016)
Invasive alien species impose a wide range of negative impacts in invaded ecosystems. Management strategies aiming to minimize these impacts include measures to prevent the introduction of potentially invasive species, ...
Ant assemblages have darker and larger members in cold environments
(John Wiley & Sons Ltd, 2016)
Aim In ectotherms, the colour of an individual’s cuticle may have important thermoregulatory and protective consequences. In cool environments, ectotherms should be darker, to maximize heat gain, and larger, to minimize ...
The BIOTA Observatories
(Klaus Hess Publishers, 2010)
The BIOTA Southern Africa transects (Fig. 1, on left side) have been designed to describe biodiversity changes in space and time along two major climatic gradients in the western part of southern Africa (see also ...
Fresh and dry ant body mass along the Cederberg "Coast-to-Karoo" transect
Fresh and dry body mass of ants collected along an altitudinal gradient in the Greater Cederberg Biodiversity Corridor (the CIB's Coast-to-Karoo transect).
Evaluation of the soil degradation state along fence-line contrasts
(Klaus Hess Publishers, 2010)
Five pairs of Observatories with contrasting landuse types and/ or landuse intensities, located in the Woodland Savanna, Thornbush Savanna, Nama Karoo, and Succulent Karoo biomes were investigated to examine the infl ...
Harnessing degraded lands for biodiversity conservation
(Elsevier GmbH, 2011)
Land degradation affects an estimated 24% of the global land area. While predominantly discussed as an environmental problem, degraded lands have recently been reconsidered as an untapped resource for production industries ...
