Intraspecific interactions can occur through many ways but the mechanisms can be broadly categorized as food exploitation and interference interactions. Identifying how intraspecific interactions impact life history is crucial to accurately predict how population density and structure influence dynamics. However, disentangling the effects of interference interactions from exploitation using experiments...
Seasonality has been suggested as a necessary factor for the initiation of vole population cycles in Fennoscandia. This has been well described for a latitudinal gradient. Here, we used an elevational gradient as a proxy for winter length to study how the length of the winter season correlates with the amplitude of bank vole Myodes glareolus population cycles. In addition, we studied whether the small...
Cannibalism is relatively common in herbaceous insects, but studies looking at life-history traits on conspecific versus herbaceous diets reveal a mix of outcomes. In some taxa, fitness is highest on a conspecific diet, but in others, fitness is highest on an herbaceous diet. Identifying factors that maintain the cannibalistic feeding strategy has been complicated by the interaction between the direct...
