Environmental determinants of greater flamingo foraging behaviour in an estuarine intertidal sandflat
… well researched through the use of caging and exclusion experiments. However, there is still very little known about flamingo spatial foraging preferences and the environmental cues that determine them. The purpose of this study was to investigate the foraging distributions of non-breeding …

The ecological role of feeding disturbances of the Atlantic horseshoe crab, Limulus polyphemus
… community structure was confirmed by long-term exclusion experiments in 2009 and 2010. Removal of Limulus disturbance resulted in significant increase in predatory polychaetes in both years, although there were no significant trends observed in abundance of total infauna or deposit feeding …

Drought tolerance and implications for vegetation-climate interactions in the Amazon forest
… as those imposed during a multiyear rainfall exclusion experiment or during interannual drought, trees prevent water loss by closing their stomata. We examine forest response to drought in an ecosystem model (SiB3 - the Simple Biosphere model) compared to two rainfall exclusion experiments in …

The phytoplankton communities of nine lakes, Waikato, New Zealand: a comparative study of floristics, seasonal dynamics and the influence of herbivory
… desmid species was relatively low. Zooplankton exclusion experiments using limnocorrals were carried out in an almost clear-water lake (Rotomanuka North) and in a darkly-stained lake (Maratoto). The results suggest that a reduction in grazing pressure markedly influenced phytoplankton community …

Population genetics of South African Protea L. (Proteaceae) species associated with various pollinator guilds
… many species have been confirmed by pollinator exclusion experiments. The genus has several pollination systems including birds, insects and non-flying mammals. Comparative estimates of pollinators’ outcrossing abilities are rare and confined to bird and insect guilds. Furthermore, 10 …

Understanding the role and impact of introduced honey bees in a submontane indigenous forest ecosystem
… brexioides and W. racemosa were observed using exclusion experiments. Community-level effects on invertebrate flower visitors were assessed using collection of flower visitors and assessment of community data using multivariate and other statistical approaches. Timing and availability of floral …

How vertebrate communities affect quality and yield of macadamia farms in Levubu, South Africa
… African macadamia orchards, using vertebrate exclusion experiments. Crop quality and yield were assessed and extrapolated to income values. The study furthermore focused in more detail on the impact of orchard edge habitat and farm management on bats as ecosystem service providers as well as …
