Recent land use changes, namely the intensification of agriculture and forestry as well as
the abandonment of traditional grassland management methods, have resulted in the …

The number of insect species at risk of population decline and extinction is increasing
rapidly. Yet we know almost nothing about the ecology of these species, except for at-risk …

Metapopulation models typically assume that suitable habitats occupied by local
populations and unsuitable matrix separating them form a 'black-and-white'landscape …

Ecologists often assume that range expansion will be fastest in landscapes composed
entirely of the highest‐quality habitat. Theoretical models, however, show that range …

We describe an automated radio telemetry system (ARTS) designed for estimating the
location of 0.50 g butterflies which was constructed with commercially available materials …

The overwintering population of eastern North American monarch butterflies (Danaus
plexippus) has declined significantly. Loss of milkweed (Asclepias sp.), the monarch's …

Habitat deterioration and biodiversity decline is progressing worldwide. However, these
effects may be somewhat mitigated in urban areas, which are strongly exposed to …

To plan effective conservation measures and to predict which species will be able to change
distribution in response to climate change, there is an increasing need for understanding …

Context Landscape-scale population dynamics are driven in part by movement within and
dispersal among habitat patches. Predicting these processes requires information about …

The study of butterfly movements has focused on dispersal behaviour in the framework of
population persistence in heterogeneous landscapes. The ecological significance of routine …
