Aspects of Breeding Performance of Scopoli’s Shearwater (Calonectris diomedea): The Case of the Largest Colony in Greece

Diversity
Here we report, for the first time, aspects of the breeding performance of Scopoli’s Shearwater (Calonectris diomedea) in one of its largest colonies in Europe, i.e., in the Strofades island group.

The impact of climatic conditions in wintering and breeding quarters on long-term breeding success in the Common Swift

Avian Research
Climate change can affect rainfall and temperature worldwide, and the ability of birds to react to these changes can be mirrored by studying population phenology and their breeding success.

Success breeds success in mating male reed frogs (Hyperolius marmoratus)

Proceedings of the Royal Society of London. Series B: Biological Sciences, 1998
Studies of the distribution of mating success among males in frog choruses typically seek to identify specific phenotypic attributes that confer a higher mating success on certain individual males. These attributes invariably relate to competition among males: either direct competition in the form of aggression, or competition to attract and be chosen ...

Half a century of environmental variability and seabird trends on the Faroe Shelf in the North Atlantic Ocean

Frontiers in Marine Science
The Faroe Shelf, located on the North Atlantic’s Iceland-Scotland ridge, has historically hosted a rich ecosystem with large seabird populations. However, substantial declines in their population sizes have been observed over the past half century.

Climate change and nest predation affect shifts in timing and duration of breeding as well as reproductive success in a migratory species

Journal of Avian Biology
While it is well known that the overall timing of avian breeding in northern latitudes has generally advanced due to climate change, it is still unclear how climate warming has affected the beginning, end, and duration of the breeding period and ...

Preparation breeds success: Brain activity predicts remembering

Cortex, 2018
Successful retrieval of episodic information is thought to involve the adoption of memory states that ensure that stimulus events are treated as episodic memory cues (retrieval mode) and which can bias retrieval toward specific memory contents (retrieval orientation).
