| bycatch in the maldivian pole-and-line tuna fishery. | tropical tuna fisheries are among the largest worldwide, with some having significant bycatch issues. however, pole-and-line tuna fisheries are widely believed to have low bycatch rates, although these have rarely been quantified. the maldives has an important pole-and-line fishery, targeting skipjack tuna (katsuwonus pelamis). in the maldives, 106 pole-and-line tuna fishing days were observed between august 2014 and november 2015. during 161 fishing events, tuna catches amounted to 147 t: 72% b ... | 2017 | 28542258 |
| keeping it regular: development of thermoregulation in four tropical seabird species. | the thermoregulatory capacity of a species can determine which climatic niche it occupies. its development in avian chicks is influenced by numerous factors. furthermore, it is suggested that altricial chicks develop their thermoregulatory capacity post-hatching, while precocial chicks develop aspects of this in the egg. we investigated the development of thermoregulation of four co-occurring seabird species in the seychelles; namely white, ground-nesting white-tailed tropicbirds (phaethon leptu ... | 2017 | 28166941 |
| mercury in seabird feathers: insight on dietary habits and evidence for exposure levels in the western indian ocean. | breast feathers were used to estimate mercury levels in six marine birds nesting in the tropical western indian ocean, i.e. sooty tern (sterna fuscata), brown noddy (anous stolidus), lesser noddy (anous tenuirostris), audubon shearwater (puffinus lherminieri bailloni), barau's petrel (pterodroma baraui) and the white-tailed tropicbird (phaethon lepturus). juveniles consistently showed lower plumage mercury than adults. the lowest mean level was noted in juvenile sooty terns from the glorioso arc ... | 2007 | 17659323 |
