Abstract We modeled the relationship between egg flotation and age of a developing embryo
for 24 species of shorebirds. For 21 species, we used regression analyses to estimate …

Matings between close relatives often reduce the fitness of offspring, probably because
homozygosity leads to the expression of recessive deleterious alleles 1 , 2 , 3 , 4 , 5 . Studies of …

The Arctic is entering a new ecological state, with alarming consequences for humanity.
Animal-borne sensors offer a window into these changes. Although substantial animal tracking …

Millions of birds migrate to and from the Arctic each year, but rapid climate change in the

The behavioural rhythms of organisms are thought to be under strong selection, influenced
by the rhythmicity of the environment 1 , 2 , 3 , 4 . Such behavioural rhythms are well studied …

Lemmings are a key component of tundra food webs and changes in their dynamics can affect
the whole ecosystem. We present a comprehensive overview of lemming monitoring and …

The ecological consequences of climate change have been recognized in numerous species,
with perhaps phenology being the most well‐documented change. Phenological changes …
