«Our observation that groups matched their compositions to the one optimal at their site of origin (regardless of their current habitat) is particularly important,» Pruitt and Goodnight write, «given that many respected researchers have argued that group selection can not lead to group adaptation except in clonal groups and that group selection theory is inefficient and bankrupt.»
«Therefore, this study adds important new evidence on the safety of neonicotinoid use, but we still can not exclude the impact of other pesticides and habitat loss on the current bee declines.
The length of the growing season in interior Alaska has increased 45 % over the last century7 and that trend is projected to continue.8 This could improve conditions for agriculture where moisture is adequate, but will reduce water storage and increase the risks of more extensive wildfire and insect outbreaks across much of Alaska.9, 10 Changes in dates of snowmelt and freeze - up would influence seasonal migration of birds and other animals, increase the likelihood and rate of northerly range expansion of native and non-native species, alter the habitats of both ecologically important and endangered species, and affect ocean currents.11
For example, reductions in seasonal sea ice cover and higher surface temperatures may open up new habitat in polar regions for some important fish species, such as cod, herring, and pollock.128 However, continued presence of cold bottom - water temperatures on the Alaskan continental shelf could limit northward migration into the northern Bering Sea and Chukchi Sea off northwestern Alaska.129, 130 In addition, warming may cause reductions in the abundance of some species, such as pollock, in their current ranges in the Bering Sea131and reduce the health of juvenile sockeye salmon, potentially resulting in decreased overwinter survival.132 If ocean warming continues, it is unlikely that current fishing pressure on pollock can be sustained.133 Higher temperatures are also likely to increase the frequency of early Chinook salmon migrations, making management of the fishery by multiple user groups more challenging.134
They warned «sea ice has been projected to disappear in the 2030s or before» and lost sea ice was both a future and «current threat to this important habitat of the polar bear.»
