organisms? Daniel Oro
Inglés3 oct. 20161097Compared to most wildlife groups, many species of albatrosses and shearwaters are relatively easy to capture at breeding colonies. This has allowed researchers to mark and recapture individuals over the years, even for several decades. This has resulted in an outstanding number of studies estimating a range of demographic parameters (including survival, recruitment and dispersal) and assessing ...

Seabird research for conservation: past successes, future prospects. John Croxall
Inglés3 oct. 2016941Originalment les accions de conservació són fetes per persones compromeses en una sola espècie/llocs, i la recerca vinculada van ser limitades. Recentment intervencions de conservació d'aus marines han estat a més gran escala (múltiples espècies i/o llocs), vinculades a la investigació aplicada dirigida (incloent la priorització d'anàlisi i desenvolupament de noves tècniques) i el ...

Inglés3 oct. 20161024Albatrosses and petrels are charismatic species of the open ocean, and their major lineages are characterized by diverse morphologies and ecologies. However, understanding their taxonomy and systematics has been challenging. Hypotheses have been obtained from examination of osteology, fine-scale morphological details, single gene sequences, and even the helical twists of their intestines. These ...

Shirihai, shows an overview of the text sections (general section on biology, and species sections), and will finally present how we are going to deal with two particular aspects of the monograph: species limits and systemathics of petrels, and distribution ...
Life time foraging and link with fisheries in albatrosses. Henri Weimerskirch
Life time foraging and link with fisheries in albatrosses. Henri Weimerskirch
Inglés3 oct. 20161075In particular fisheries have known to have affected albatross populations by increasing mortality to unsustanaible rates. Here I review how albatrosses change their foraging behavior over their life time, and how it can have been affected by fisheries.6th International Albatross and Petrel Conference, 19-23th september 2016, at Historic Building of University of Barcelona.

Inglés3 oct. 2016990Modern tracking technologies are now starting to allow this observation indirectly, so that finally we are able to enrich our understanding of the shearwater's world. In this presentation I bring together both experimental work and technology-enabled observation, conducted by a research group on shearwater life-history.6th International Albatross and Petrel Conference, 19-23th september ...

Ocean. Matthieu Le Corre
Inglés3 oct. 20161037Population models show that these threats may lead to population collapses if nothing is done and I will shortly review some important conservation programs that are conducted locally to reverse this trend. We did not find any evidence of incidental catches by longliners or by purse-seiners so far, which suggest that, contrary to numerous species of petrels and shearwaters around the world, our ...

Inglés3 oct. 20161205The WWF signed to buy the islands, but the Government exercised their option, bought them and declared them a Strict Nature Reserve. In 1976 the islands were ransacked by Madeira fishermen. Alec Zino took a TV team to see the damage and the resulting film caused Lisbon to take action. Wardens have since been present on the islands.6th International Albatross and Petrel Conference, ...

conservation. Thierry Boulinier
Inglés3 oct. 2016931Infectious diseases are a relatively neglected but potentially important threat to poulations of albatrosses and petrels. This is notably so for species breeding in dense aggregations, which can be the subject of recurrent local epizooties, such as in the case of avian cholera in albatrosses of Amsterdam Island, in the Southern Indian Ocean. They have potentialliy interesting model systems to ...
Workshop I. Data Challenge on Behavioural Annotation
Workshop I. Data Challenge on Behavioural Annotation
Inglés30 sep. 20161000Nowadays there are an increasing number of methods to infer putative behaviours from tracking data. For that reason, the criteria is not trivial to select the more appropriate method according to the characteristics of each dataset or the questions to resolve.The goal of the workshop is to discuss and share the results from different behavioural segmentation algorithms in order to discuss ...

The first goal of this workshopp will be to understand the technology in details in order to better understand the sources of the errors. The second goal of this workshop will be to review the methods used to deal with these errors. A selected data set of tracks will be provided for the ...

Inglés30 sep. 2016997Els senyals químics han estat probablement els primers senyals cada vegada utilitzats pels organismes per avaluar el seu entorn, i per comunicar-se entre ells. Aquests senyals són àmpliament utilitzats pels invertebrats i els vertebrats, però els ocells poques vegades exhibeixen conductes olfactòries òbvies, i han estat poc investigades. No obstant això, a poc a poc, la investigació ...
