Larval competition for patchy resources in Chrysomya megacephala (Dipt., Calliphoridae): implications of the spatial distribution of immatures
(Blackwell Verlag Gmbh, 2001-12-01)
In the present study, a single procedure was established to investigate the effect of the spatial distribution of immatures in patchy resources, on the outcome of larval competition for food. in experimental populations ...
Optimal zoning in spatial differentiation
(Universidad de Chile. Facultad de Economía y Negocios, 2017)
This study analyzes optimal zoning policy in a duopolistic spatial competition
framework for both circular and linear spaces. A regulator is introduced in
the third stage of the price-location game through a welfare ...
A sexual network approach to sperm competition in a species with alternative mating tactics
(International Society for Behavioral EcologyCary, 2014-09)
Alternative mating tactics are common among species exhibiting resource defense polygyny. While large territorial males aggressively defend harems, small sneaker males generally invade these harems to mate furtively. The ...
Movement behaviour determines competitive outcome and spread rates in strongly heterogeneous landscapes
(2018-09-01)
Classical models for biological invasions were single-species models in homogeneous landscapes, but most invasions happen in the presence of interacting species and in heterogeneous environments. The combination of spatial ...
Estimating economic interactions of financial suppliers in Thailand
(Escola de Pós-Graduação em Economia da FGV, 2004-05-20)
This paper presents a methodology to estimate and identify different kinds of economic interaction, whenever these interactions can be established in the form of spatial dependence. First, we apply the semi-parametric ...

SEASONAL MICROHABITAT SELECTION BY TERRESTRIAL RODENTS IN AN OLD-GROWTH ATLANTIC FOREST
(ALLIANCE COMMUNICATIONS GROUP DIVISION ALLEN PRESS, 2009)
We tested the hypothesis that microhabitat variables, abundance of terrestrial rodents, and microhabitat selection patterns of terrestrial rodents vary between the cool-dry and warm-wet season in the Atlantic forest of ...
