The increasing human impact on the earth's biosphere is inflicting changes at all spatial scales. As well as deterioration and fragmentation of natural biological systems, these changes also led to other, unprecedented effects and emergence of novel habitats. In boreal zone, intensive forest management has negatively impacted a multitude of deadwood-associated species. This is especially alarmi...

Forest fragmentation may cause increased brood parasitism and nest predation of breeding birds. In North America, nest parasitism and predation are expected to increase closer to forest edges because the brood-parasitic Brown-headed Cowbird (Molothrus ater) and generalist nest predators often enter the forest from adjoining developed (largely agricultural) habitats. Yet the abundance of brood p...

Kelp habitats are threatened across the globe, and because of their ecological importance, active conservation restoration solutions needed. The use man-made structures as artificial reefs is one way to enhance kelp habitat by providing suitable substrata, but in past ecology has been investigated mainly contrast natural coastal habitats, not elements integrated into seascape. Indeed, it now em...

background: coverage of the bronchial stumps (bss) with adjacent tissues can improve healing and reduce bronchial complications in complex thoracic surgery. there is no evidence for the application of human amnion allograft for prevention of air leak from the bs. the comparison of the amniotic membrane (am) and pleural patch for bs healing after lobectomy in dogs was our aim in this study. mate...

Movement and exchange of individuals among habitats is critical for the dynamics and success of reef fish populations. Size segregation among habitats could be taken as evidence for habitat connectivity, and this would be a first step to formulate hypotheses about ontogenetic inter-habitat migrations. The primary goal of our research was to find evidence of inter-habitat differences in size dis...

Artificial structures can create novel habitat in the marine environment that has been associated with the spread of invasive species. They are often located in areas of high disturbance and can vary significantly in the area of free space provided for settlement of marine organisms. Whilst correlation between the amount of free space available and recruitment success has been shown in populati...

Nest predators can adversely affect the viability of songbird populations, and their impact is exacerbated in fragmented habitats. Despite substantial research on this predator-prey interaction, however, almost all of the focus has been on the birds rather than their nest predators, thereby limiting our understanding of the factors that bring predators and nests into contact. We used radiotelem...
