Context Landscape structure influences host–parasite–pathogen dynamics at multiple
scales in space and time. Landscape epidemiology, which connects disease ecology and …

Context Landscape sustainability emerges from interactions between linked human and
natural systems. Many of these interactions are mediated by institutions (eg, rules, laws …

How the resource use by consumers vary in different environments and time scales is one of
the fundamental ecological questions. Replicated field studies are rare, however; so the …

The timing and duration of each stage of the life of a long‐distance migrant bird are
constrained by time and resources. If the parental roles of males and females differ, the …

Metacommunity theory provides a framework for assessing the role of spatial and
environmental processes in structuring ecological communities and places emphasis on the …

The community dynamics of organisms that exhibit multi‐scale responses to habitat change
are poorly understood. We quantified changes in species diversity and the functional …

We studied two populations of Boeckella gracilipes and two populations of Boeckella
gibbosa that inhabit mountain lakes from North‐Patagonian Andes with different optical …

Body mass and organ size dynamics during flight-feather moult vary among waterfowl
species. To better understand adaptations of the African waterfowl, we measured how body …

Chemicals do not occur alone in the environment but most ecotoxicological assessments
target the effect of single chemicals on aquatic communities and the establishment of legal …

The aims of the dissertation are to describe long term migrant and residential wader
population trends at Strandfontein, and to identify the potential factors which influence local …
