Relative Roles of Grey Squirrels, Supplementary Feeding, and Habitat in Shaping Urban Bird Assemblages
Non-native species are frequently considered to influence urban assemblages. The grey squirrel Sciurus carolinensis is one such species that is widespread in the UK and is starting to spread across Europe; it predates birds' nests and can compete with birds for supplementary food. Using distance sampling across the urbanisation intensity gradient in Sheffield (UK) we test whether urban grey squ...

Their sisters tiple, complementary perspectives. Separating these levbehave quite differently, remaining near home throughels of analysi...
متن کاملSquirrels Reveal Bits of Hibernome
Mammalian hibernators are unique in their ability to cope with freezing temperatures. Some mammals can lower their body temperatures to as low as –2.9°C for several weeks. In the golden-mantle ground squirrel, Spermophilus lateralis, this period of low body temperature, called torpor, is interrupted by arousals during which body temperature rises as much as 30°C in a matter of hours. Squirrels ...
متن کاملOperational Application of Diversionary Food in Young Lodgepole Pine Forests to Reduce Feeding Damage by Red Squirrels
The use of diversionary food is an ecological method to reduce feeding damage by wildlife to forest and agricultural crops. The red squirrel (Tamiasciurus hudsonicus) feeds on the vascular tissues of young lodgepole pine (Pinus contorta var. latifolia) and this damage is particularly severe in intensively managed stands. Aerial application of sunflower seed on an operational scale significantly...
متن کاملFeeding of grey squirrels (Sciurus carolinensis) with the contraceptive agent DiazaCon™: effect on cholesterol, hematology, and blood chemistry.
Grey squirrels (Sciurus carolinensis) are an invasive species in Britain and Italy. They have replaced native red squirrels (Sciurus vulgaris) throughout most of Britain, and cause damage to trees. Currently, lethal control is used to manage grey squirrel populations in Britain, but nonlethal methods might be more acceptable to the public. One such method is contraception with 20,25-diazacholes...
