Impacts of climate change on Emperor Penguins (Aptenodytes forsteri)

by Yadav Sharma Bajagai Emperor penguins ( Aptenodytes forsteri) are regarded as an icon of Antarctica due to its peculiar appearance and behaviour. These are the largest of all penguins adapted to extreme climatic condition of Antarctica [ 1 ] and are particularly susceptible to environmental changes in southern ocean as a result of global climate change due to being ice-obligate species [ 2 ] . Size of the bird also increases its susceptibility to climate change [ 3 ] and its morphology which prevent them to forage up to greater depth and range make the situation even worse [ 2 ] . Alteration in sea ice condition, which ultimately affects availability of pray and breeding and moulting of these birds, significantly affects their population [ 2 ] . 

Impacts of climate change on Pig

by Yadav Sharma Bajagai Swine are particularly susceptible to increased environmental temperature because evaporative cooling by sweating is of limited value to them due to barely functional sweat glands. Impacts of thermal stress on pig due to increased ambient temperature are described here briefly.   For Impacts of Climate Change on Cattle , Click Here.
