organisms? Daniel Oro biología Inglés3 oct. 20161411Compared 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 biología Inglés3 oct. 20161212Originalment 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 ...

New approaches to an old question: exploring the evolutionary history of albatrosses and petrels. Andreanna J. ...
Welch biología Inglés3 oct. 20161347Albatrosses 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 ...

Focus on the plates painted by Tim Workfolk, the photos of H. 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 biología Inglés3 oct. 20161412In 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.
