Mechanistic models for predicting insect responses to climate change
Mechanistic models of the impacts of climate change on insects can be seen as very specific hypotheses about the connections between microclimate, ecophysiology and vital rates. These models must adequately capture ...
First record of the invasive red palm mite Raoiella indica Hirst (Acari: Tenuilpidae) in Namibia
(Entomological Society of Southern Africa, 2016)
Basal metabolic rate of the black-faced sheathbill (Chionis minor): Intraspecific variation in a phylogenetically distinct island endemic
(The University of Chicago, 2016)
Metabolic rate is a fundamental characteristic of all organisms. It covaries most significantly with activity, body mass, seasonality, and temperature. Nonetheless, substantial additional variation in metabolic rate, ...
Science and education at the Centre for Invasion Biology
(Springer International Publishing, 2016)
South Africa has severe problems caused by biological invasions in terrestrial, freshwater and marine ecosystems, and a long history of managing biological invasions. However, appreciation and systematic study of the ...
Understanding and managing the introduction pathways of alien taxa: South Africa as a case study
For the effective prevention of biological invasions, the pathways responsible for introductions must be understood and managed. However introduction pathways, particularly for developing nations, have been understudied. ...
The structure of the littoral: effects of waterlily density and perch predation on sediment and plant-associated macroinvertebrate communities
(John Wiley & Sons Ltd, 2016)
1. Littoral zones are complex and important for mechanisms that maintain clear water and submerged plant dominance in lakes. Details of their structure are scarce, largely because sweep or grab sampling, the most commonly ...
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, ...
Soil biota in a megadiverse country: Current knowledge and future research directions in South Africa
(Elsevier GmbH, 2016)
Soils are integral to agricultural productivity, biodiversity, and the maintenance of ecosystem services. However, soil ecosystem research depends on foundational biological knowledge that is often missing. In this review, ...
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 ...
Sani Pass climate data 2015
The Sani Pass long term site investigate the effects of inter-annual variation on ant and spider assemblages and the climate the invertebrates experience at 8 sites on the Sani Pass region of the Drakensberg in the Eastern ...
