From birds to butterflies: animal movement patterns and stable isotopes.
Establishing patterns of movement of wild animals is crucial for our understanding of their ecology, life history and behavior, and is a prerequisite for their effective conservation. Advances in the use of stable isotope markers make it possible to track a diversity of animal species in a variety of habitats. This approach is revolutionizing the way in which we make connections between phases ...
متن کاملBirds and Butterflies in Swedish Urban and Peri-urban Habitats: a Landscape Perspective
Hedblom, M. 2007. Birds and butterflies in Swedish urban and peri-urban habitats: a landscape perspective. Doctor's dissertation. Urbanisation is considered to be one of the largest threats to biodiversity although little is known about the effect of habitat fragmentation on native flora and fauna in urban areas in general, and in Sweden specifically. In this thesis, data have been collected us...
متن کاملCitizen Science and the Urban Ecology of Birds and Butterflies — A Systematic Review
Citizen science has gained widespread currency as a tool for ecological research over the past decade. However, in the discipline of urban ecology, the existing contributions and future potential of citizen science engagement, specifically in terms of knowledge gain, have not yet been comprehensively explored. Here, we present a systematic review of published work on the urban ecology of birds ...
متن کاملA protean palette: colour materials and mixing in birds and butterflies.
While typically classified as either 'structural' or 'pigmentary', bio-optical tissues of terrestrial animals are rarely homogeneous and typically contain both a structural material such as keratin or chitin and one or more pigments. These base materials interact physically and chemically to create colours. Combinations of structured base materials and embedded pigment molecules often interact ...
متن کاملComparative losses of British butterflies, birds, and plants and the global extinction crisis.
There is growing concern about increased population, regional, and global extinctions of species. A key question is whether extinction rates for one group of organisms are representative of other taxa. We present a comparison at the national scale of population and regional extinctions of birds, butterflies, and vascular plants from Britain in recent decades. Butterflies experienced the greates...
