DOI: 10.1002/ece3.5067
Abstract: Abstract The difficulty in studying nonbreeding birds means that little is known about them or their resource requirements, despite forming a large and significant component of a population. One way to assess food requirements is… read more here.

Earlier and more frequent occupation of breeding sites during the non‐breeding season increases breeding success in a colonial seabird

DOI: 10.1002/ece3.9213
Abstract: Abstract Competition for high‐quality breeding sites in colonial species is often intense, such that individuals may invest considerable time in site occupancy even outside the breeding season. The site defense hypothesis predicts that high‐quality sites… read more here.

No seasonal curtailment of the Eurasian Skylark's (Alauda arvensis) breeding season in German heterogeneous farmland

DOI: 10.1002/ece3.9267
Abstract: Abstract The lack of suitable nesting sites is one key driver behind the farmland bird crisis in Europe. Winter cereals become impenetrable for ground‐breeding birds like the Eurasian Skylark (Alauda arvensis), curtailing breeding time. Stable… read more here.

No relationship between chronotype and timing of breeding when variation in daily activity patterns across the breeding season is taken into account

DOI: 10.1002/ece3.9353
Abstract: Abstract There is increasing evidence that individuals are consistent in the timing of their daily activities, and that individual variation in temporal behavior is related to the timing of reproduction. However, it remains unclear whether… read more here.

Singing behind the stage: thrush nightingales produce more variable songs on their wintering grounds

DOI: 10.1007/s00265-019-2765-x
Abstract: The songs of migratory passerine birds have a key role in mate attraction and territory defence during the breeding season. Many species also sing on their wintering grounds, but the function of this behaviour remains… read more here.

DOI: 10.1007/s10750-017-3362-5
Abstract: The acorn barnacle Perforatus perforatus has a defined breeding temperature range and reproductive season that varies geographically. This study aims to investigate the influence of reproductive parameters of P. perforatus in species distribution ranges in… read more here.

Abstract: The effects of a shortened photoperiod on the reproductive performance and hormones of mature dromedary camel bulls (Camelus dromedarius) were evaluated. A group of 6 bulls were blindfolded to induce a daily photoperiod that was… read more here.

DOI: 10.1016/j.aquaculture.2020.735677
Abstract: Abstract An understanding of how seasonality impacts amphibian's sperm quality is crucial for the development and implementation of assisted reproductive technologies for threatened species. We analysed sperm quality both within and outside the breeding season… read more here.

DOI: 10.1016/j.marenvres.2020.105157
Abstract: The increasing development of offshore wind farms (OWFs) worldwide leads to possible conflicts with the ecological requirements of top predators that largely depend on offshore areas. Seabird species exhibit different behavioural reactions to OWFs, ranging… read more here.
