A potential ant-hemiptera-plant mutualism on Lorostemon coelhoi (Clusiaceae) in the Brazilian Amazon [PDF]
Acta AmazonicaInteractions among organisms are important in ecosystem functioning and relevant for the management and conservation of species. Here we report the first record of a potential ant-hemiptera-plant mutualism on Lorostemon coelhoi (Clusiaceae) in Manaus ...

Pathogens, 2023 Grazing systems have great potential to promote animal welfare by allowing animals to express natural behaviours, but they also present risks to the animals. Diseases caused by gastrointestinal nematodes are some of the most important causes of poor ruminant health and welfare in grazing systems and cause important economic losses.

Changes in seed dispersal processes and the potential for between-patch connectivity for an arid land daisy [PDF]
, 2012 Dispersal is a major and critical process in population biology that has been particularly challenging to study. Animals can have major roles in seed dispersal even in species that do not appear specifically adapted to animal-aided dispersal.

The variation in morphology of perennial ryegrass cultivars throughout the grazing season and effects on organic matter digestibility [PDF]
, 2013 peer-reviewedThe grass plant comprises leaf, pseudostem, true stem (including inflorescence) and dead material. These components differ in digestibility, and variations in their relative proportions can affect sward quality.

Effect of daily movement of dairy cattle to fresh grass in morning or afternoon on intake, grazing behaviour, rumen fermentation and milk production [PDF]
, 2009 Twenty Holstein cows were split into two equal groups to test the effect of daily move to a previously ungrazed strip after morning milking (MA) or afternoon milking (AA) on herbage intake, grazing behaviour, rumen characteristics and milk production ...

A theory for investment across defences triggered at different stages of a predator-prey encounter [PDF]
, 2019 We introduce a general theoretical description of a combination of defences acting sequentially at different stages in the predatory sequence in order to make predictions about how animal prey should best allocate investment across different defensive ...
