Estos datos fueron utilizados en la evaluación de la sensibilidad sexo-específica en el crecimiento en peso corporal de pichones de Cormorán Imperial (Leucocarbo atriceps). Los mismos también se encuentran disponibles en ...
Breeding experience and foraging behaviour of Imperial Shags (Leucocarbo atriceps) in Argentina
(Csiro Publishing, 2014-03)
Breeding success depends on efficient foraging behaviour by breeding individuals. However, foraging skills are acquired over time and foraging behaviour is expected to be optimised over the course of successive breeding ...
Sex-specific environmental sensitivity on the postnatal growth of a sexually size-dimorphic seabird
(Wiley Blackwell Publishing, Inc, 2020-12)
The environment experienced during development is a key factor determining intraspecific variation in postnatal growth. In sexually size-dimorphic species, the larger sex typically grows at a higher absolute rate and ...
Leg rings impact the diving performance of a foot-propelled diver
(Wiley Blackwell Publishing, Inc, 2021-07)
Leg rings are frequently used to mark aquatic birds in order to identify individuals, and study population dynamics and migration patterns, with the proviso being that the rings should not affect the birds. The effects of ...
Lousy chicks: Chewing lice from the Imperial Shag, Leucocarbo atriceps
(Australian Society for Parasitology, 2017-12)
Forty-one imperial shag chicks were sampled for lice during the breeding season of 2014 in Punta León, Argentina. We found 2 lice species, Pectinopygus turbinatus infesting the body and Piagetiella caputincisum present in ...
Population trends of Imperial Cormorants (Leucocarbo atriceps) in northern coastal Argentine Patagonia over 26 years
(Taylor & Francis, 2020-04)
Monitoring programmes are essential for detecting population changes, but data series are difficult to sustain over time. Additionally, wide-scale monitoring is needed to adequately interpret demographic behaviour given ...
Heat‑related massive chick mortality in an Imperial Cormorant Leucocarbo atriceps colony from Patagonia, Argentina
(Springer, 2022-02)
Climate change has exacerbated the frequency and severity of heat waves, which on occasion lead to mass mortalities. Here, we report a massive mortality event in Imperial Cormorant Leucocarbo atriceps chicks that took place ...
Rapid radiation of Southern Ocean shags in response to receding sea ice
(Wiley Blackwell Publishing, Inc, 2022-03)
Aim: Understanding how natural populations respond to climatic shifts is a fundamental goal of biological research in a fast-changing world. The Southern Ocean represents a fascinating system for assessing large-scale ...
Corrigendum to “Lousy chicks: Chewing lice from the imperial shag, Leucocarbo atriceps”
(Australian Society for Parasitology, 2018-08)
The authors regret an involuntary mistake in the specific determination of Pectinopygus turbinatus, where the correct name is Eidmanniella pellucida. As follow we present the revised taxonomic review for this species: ...
Novel morphological and molecular data for Corynosoma hannae Zdzitowiecki, 1984 (Acanthocephala: Polymorphidae) from teleosts, fish-eating birds and pinnipeds from New Zealand
(Elsevier Ireland, 2017-02)
The polymorphid acanthocephalan, Corynosoma hannae Zdzitowiecki, 1984 is characterised on the basis of newly collected material from a New Zealand sea lion, Phocarctos hookeri (Gray), and long-nosed fur seal, Arctophoca ...
