A mathematical epidemiological model of gram-negative Bartonella bacteria: Does differential ectoparasite load fully explain the differences in infection prevalence of Rattus rattus and R. norvegicus?
(Taylor & Francis, 2012)
We postulate that the large difference in infection prevalence, 24% versus 5%, in R. norvegicus and R. rattus, respectively, between these two co-occurring host species may be due to differences in ectoparasite and potential ...
Temporal changes in cranial size in South African vlei rats (Otomys): evidence for the ‘third universal response to warming’
(NISC (Pty) Ltd and Taylor & Francis, 2015)
Using museum collections and recently collected specimens we studied geographical and temporal (from 1906 to 2013) changes in skull size of two sibling species of rodents, Otomys auratus and O. angoniensis, in northern ...
The relationship between cranial morphology, bite performance, diet and habitat in a radiation of dwarf chameleon (Bradypodion)
(The Linnian Society of London, 2016)
Many animals show unique morphological and behavioural adaptations to specific habitats. In particular, variation in cranial morphology is known to influence feeding performance, which in turn influences dietary habits ...
Indicators for monitoring biological invasions at a national level
(British Ecological Society, 2018)
1. A major challenge for the management of biological invasions is to ensure that data and information from basic inventories and ecological research are used alongside data from the monitoring and evaluation of interventions ...
Foliar nitrogen dynamics of an invasive legume compared to native non-legumes in fynbos riparian zones varying in water availability
(Creative Commons Attribution License, 2019)
The legume Acacia mearnsii invades South Africa’s fynbos riparian zones and may alter the nitrogen (N) dynamics and supply in these areas that typically support few native N fixers. Nitrogen uptake by A. mearnsii may also ...
Alien bamboos in South Africa: a socio-historical perspective
Changes in fashions and economic imperatives underlying plant introductions have a profound influence on the movement of species around the world. Using bamboo introductions into South Africa as a case-study, we explore ...
