1. 1. Evolutionary implications of acidification: a frog’s eye view

   Författare :Katja Räsänen; Andrew Hendry; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; acid stress; amphibians; local adaptation; maternal effects; maternal investment; Biologi; Biology; Biologi; populationsbiologi; Population Biology;

   Sammanfattning : Understanding the diversity of life is one of the main aims of evolutionary biology, and requires knowledge of the occurrence and causes of adaptive genetic differentiation among geographically distinct populations. Environmental stress caused by acidity may cause strong directional selection in natural populations, but is little explored from an evolutionary perspective. LÄS MER

3. 2. Evolutionary consequences of maternal effects and stress

   Författare :Piotr K. Rowiński; Björn Rogell; Karl Gotthard; Katja Räsänen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parental effects; meta-analysis; development time; bet-hedging; brain size; evolutionary potential; unpredictable environments; zoologisk ekologi; Animal Ecology;

   Sammanfattning : Maternal effects occur when maternal environment or phenotype influence offspring phenotype, in addition to genetic contribution of the mother. As maternal effects often influence phenotypes that are under natural selection, they hence have evolutionary consequences. LÄS MER
