BEHAVIOURAL INDICATORS OF INTRA- AND INTER-SPECIFIC COMPETITION: SHEEP CO-GRAZING WITH GUANACO IN THE PATAGONIAN STEPPE

Behavioural Indicators of Intra- and Inter-Specific Competition: Sheep Co-Grazing with Guanaco in the Patagonian Steppe

In extensive livestock production, high densities may inhibit regulation processes, maintaining high levels of intraspecific competition over time.During competition, individuals typically modify their behaviours, particularly feeding and bite rates, which can therefore be used as indicators of competition.Over eight consecutive seasons, we investi

Are we on the right track: can our understanding of abscission in model systems promote or derail making improvements in less studied crops?

As the world population grows and resources and climate conditions change, crop improvement continues to be one of the most important challenges for agriculturalists.The yield and quality of many crops is affected by abscission or shattering, and environmental stresses often hasten or alter the abscission process.Understanding this process can not

Involvement of two uptake mechanisms of gold and iron oxide nanoparticles in a co-exposure scenario using mouse macrophages

Little is known about the simultaneous uptake of different engineered nanoparticle types, as it can be expected in our daily life.In order to test such co-exposure effects, murine macrophages (J774A.1 cell line) were incubated with gold (AuNPs) and iron oxide nanoparticles (FeOxNPs) either alone or combined.Environmental scanning electron microscop
