Variability in size of groups in communal roosts: influence of age-class, abundance of individuals and roosting site
(Csiro Publishing, 2013-06)
Many birds use communal roosts, but how they use them is generally poorly known. For conservation purposes, and to better understand communal roosting behaviour, it is important to know which factors produce variability ...
Population Balance Discretization for Growth, Attrition, Aggregation, Breakage and Nucleation
(Elsevier, 2015-08-28)
This paper presents a new discretization method to solve the population balance equation (PBE) for batch and unsteady/steady-state continuous perfectly-mixed systems. The numerical technique is valid for any size change ...

Evolution of brain size in class-based societies of fungus-growing ants (Attini)
A social lifestyle is often assumed to be more complex than a solitary one, due to social demands that may require increased cognitive capabilities. These nested assumptions underlie hypotheses to explain a correlation ...
Size-Dependent Selective Mechanisms on Males and Females and the Evolution of Sexual Size Dimorphism in Frogs
(Univ Chicago Press, 2014-12-01)
Sexual size dimorphism (SSD) varies in animals from male biased to female biased. The evolution of SSD is potentially influenced by a number of factors, such as territoriality, fecundity, and temporal breeding patterns ...
