Skewed adult sex ratio (ASR) has been proposed as a common pattern in birds, frequently biased towards males and with larger biases in globally threatened species. In albatrosses and petrels, it has been suggested that differential mortality of one gender in fisheries is caused either by sexual size dimorphism giving males a competitive advantage, which allows more access of the larger sex (i.e. males) to discards and/or baits, or to at sea segregation of sexes. Here, we tested these hypotheses… Expand

Figures and Tables from this paper

Sexual size dimorphism, spatial segregation and sex-biased bycatch of southern and northern royal albatrosses in pelagic longline fisheries
TLDR
Based on a large sample of albatrosses bycaught off Uruguay, both species showed substantial SSD, indicating sexual segregation at sea, and discriminating functions presented enable species and sex to be identified, providing critical data for future bycatch assessments. Expand
Sex-related variation in the vulnerability of wandering albatrosses to pelagic longline fleets
The population of wandering albatrosses Diomedea exulans at South Georgia is decreasing because of bycatch in longline fisheries. Until at least the early 1990s, the survival rate of females wasExpand
Male-biased adult sex ratio in non-breeding areas of an extreme long-distance migratory shorebird population
TLDR
It is found that this godwit population, which breeds in Alaska, does not present a large-scale sexual segregation between non-breeding sites but is overall male-biased (ASR = 0.59). Expand
Sex-specific foraging behaviour and a field sexing technique for Endangered African penguins
TLDR
Female behaviour in African penguins may make them more at risk from predation or oiling events, highlighting the possibility of sex-dependent vulnerability in this Endangered species. Expand
Sexual segregation in distribution, diet and trophic level of seabirds: insights from stable isotope analysis
TLDR
Sex differences in isotope signatures were much more common in seabirds during the pre-laying or breeding than the nonbreeding period, presumably reflecting greater between-sex partitioning of resources when foraging ranges are more constrained and competition is greater. Expand
Does sexual segregation occur during the nonbreeding period? A comparative analysis in spatial and feeding ecology of three Calonectris shearwaters
TLDR
It is proposed that SS in these seabird species might have its origin in an ecological specialization derived from the different roles of males and females during reproduction, rather than from social dominance during the nonbreeding period. Expand
Sex differences in migration and demography of a wide-ranging seabird, the northern gannet
TLDR
It is revealed that female gannets are more likely to travel further than males to winter in the CCLME, unlike in other bird species, and the reason for slightly higher over-winter female mortality at Grassholm is unclear. Expand
Global patterns of sex- and age-specific variation in seabird bycatch
TLDR
It is recommended that researchers track individuals of different sex and age classes to improve knowledge of their distribution, relative overlap with vessels, and hence susceptibility to bycatch, and data on sex, age and provenance of bycaught birds should be collected by fisheries observers to improve targeting of bycatch mitigation and monitoring of compliance. Expand
Seasonal Sexual Segregation by Monomorphic Sooty Shearwaters Puffinus griseus Reflects Different Reproductive Roles during the Pre-Laying Period
TLDR
Application of bird-borne geolocation-immersion loggers revealed seasonal segregation in the sexually-monomorphic Sooty Shearwater Puffinus griseus, mainly in the pre-laying period, when there were clear differences in reproductive roles. Expand
Contribution of fishery discards to the diet of the Black-browed albatross (Thalassarche melanophris) during the non-breeding season: an assessment through stable isotope analysis
TLDR
Results indicate that during their non-breeding season, isotopic signatures of Black-browed albatrosses are closer to discards and offal generated by fisheries and in particular by trawlers. Expand

Population sex ratio shift from fledging to recruitment: consequences for demography in a philopatric seabird
TLDR
It is suggested that natal males have a greater influence on natal population growth rate than natal females, and sex biased dispersal is the most probable reason for higher emigration to and immigration from other colonies in females, the less territorial and less philopatric sex. Expand
Sex determination and sexual size-dimorphism in Southern Giant-Petrels (Macronectes giganteus) from Patagonia, Argentina
TLDR
Bill-length alone was sufficient to predict sex of adults and fledglings and can thus serve as a simple and effective tool for sexing Southern Giant-Petrels. Expand
Age Composition and sexual size dimorphism of albatrosses and petrels off Brazil
TLDR
For this heterogeneous community composed of individuals from different colonies, with adults and immature birds pooled, the SSD was more pronounced in bill measurements than in other traits and more conspicuous in giant petrels and Diomedea albatrosses. Expand

Seabird mortality associated with Patagonian Toothfish (Dissostichus eleginoides) longliners in Falkland Islands waters
TLDR
The observed mortality in the Patagonian Toothfish longline fishery in Falkland Islands waters in 2001–02 was 29 seabirds, including 27 Black-browed Albatrosses, giving an estimated total mortality of 134 birds, which suggests that this fishery is currently not contributing substantially to observed declines in the local populations. Expand
Seasonal sexual segregation in two Thalassarche albatross species: competitive exclusion, reproductive role specialization or foraging niche divergence?
TLDR
It is suggested that seasonal sexual segregation in black–browed and grey–headed albatrosses is attributable to niche divergence mediated by differences in flight performance, and may have implications for conservation in relation to sex–specific overlap with commercial fisheries. Expand
SEABIRD MORTALITY IN THE PATAGONIAN TOOTHFISH LONGLINE FISHERY AROUND CROZET AND KERGUELEN ISLANDS, 2001-2003
TLDR
The results of this study suggest that a signifi cant part of the mortality of white-chinned petrels and greyPetrels is explained by the time of year, geographical area and type of longliner (manual versus automatic baiting). Expand
Modelling impacts of long-line fishing: what are the effects of pair-bond disruption and sex-biased mortality on albatross fecundity?
TLDR
A comparative, stochastic, individual-based model was used to investigate the demographic costs of long-line mortality for the wandering albatrossDiomedeaexulans, finding that female-biased mortality increases the cost of fecundity, especially where mortality is sex-biased. Expand
