Effect of road traffic on amphibian density
We studied the effect of traffic intensity on local abundance of anurans. We counted dead and live frogs and toads per km and estimated frog and toad local abundances using breeding chorusExpand

Patchy environments and species survival: Chipmunks in an agricultural mosaic
Abstract Chipmunks were studied in woods separated by farmland and connected by fencerows. Local extinctions of chipmunks from individual woods were readily recolonised by animals from other patches.Expand

Movements by Birds and Small Mammals Between a Wood and Adjoining Farmland Habitats
(1) White-footed mice (Peromyscus leucopus) and chipmunks (Tamias striatus) moved between a beech-maple wood and connecting fencerows four times as often as they moved between traplines within theExpand

Use of spatial elements in a farmland mosaic by a Woodland Rodent
Abstract We studied the use of agricultural landscapes in eastern Ontario, Canada, by white-footed mice Peromyscus leucopus. P. leucopus was common in all patch types except hay and pasture.Expand

Population effects of landscape model manipulation on two behaviourally different woodland small mammals
We designed an individual-based simulation model to explore the effects of landscape spatial structure and connectivity on the population size and persistence of two woodland small mammal species,Expand

Invertebrate activity under snow in deciduous woods
Pitfall traps caught large numbers of representatives of 44 families of invertebrates just before snow fall and under the snow. Some groups of ectotherms were most active in late autumn and lateExpand

Local Extinctions, Habitat Fragmentation, and Ecotones
In this chapter, extinctions are explored in the context of mechanisms that operate during and after habitat fragmentation of, and with frequent references to, woodlands in farmland, where we haveExpand

Litterfall in two Canadian deciduous woods: quality, quantity and timing
Litterfall in two deciduous woods in Ontario, Canada, was caught in bag traps and by new screen traps for two years. The beech-maple wood produced 818 g m−2 (8.2 t ha−1) and the poplar wood producedExpand
