Individual variation in migratory behavior in a sub-arctic partial migrant shorebird

Verónica Méndez Aragón, Jose Alves, Bodvar Þórisson, Alina Marca, Tomas Gunnarsson & Jennifer Gill
Migratory behavior can differ markedly amongst individuals within populations or species. Understanding the factors influencing this variation is key to understanding how current environmental changes might influence migratory propensity and the distribution and abundance of migratory species across their range. Here, we investigate variation in migratory behavior of the partially migratory Eurasian oystercatcher (Haematopus ostralegus) population breeding in Iceland. We use resightings of color-ringed adults and stable isotopes to determine whether individuals migrate or remain...

Mobilisation of data to stakeholder communities: Bridging the research-practice gap using a commercial shellfish species model

Kate Mahony, Sarah Culloty, Alice Fitch, Sara Cabral, Mélanie Rocroy, Xavier De Montaudouin, Sharon Lynch, Sian Egerton & Luísa Magalhães
Knowledge mobilisation is required to “bridge the gap” between research, policy and practice. This activity is dependent on the amount, richness and quality of the data published. To understand the impact of a changing climate on commercial species, stakeholder communities require better knowledge of their past and current situations. The common cockle (Cerastoderma edule) is an excellent model species for this type of analysis, as it is well-studied due to its cultural, commercial and ecological...

Photoinhibition of photosystem II in Phytoplankton: Processes and patterns

Douglas Campbell & João Serôdio
All the diverse lineages of phytoplankters use conserved Photosystem II complexes to mediate photochemical extraction of electrons from water, with concomitant release of oxygen. Photosystem II suffers light-dependent photoinactivation through multiple mechanisms, which is in turn countered by protein subunit removal and replacement. This cycle imposes both direct costs and also delayed opportunity costs. The effective quantum yield for photoinactivation of Photosystem II depends upon taxa, cell size, prior acclimation state, the instantaneous spectral regime...

Feather isotope ratios and sexing of oystercatchers breeding in Iceland, 2013-2017

J.A. Gill, V. Mendez, T.G. Gunnarsson, J.A. Alves & B. Thorrison
Dataset comprises of the delta-13C and delta-15N stable isotopic information from feather samples (for 552 individuals) and the sex (assigned by DNA-analysis of blood samples for 321 individuals) of oystercatchers (Haematopus ostralegus) breeding in Iceland during the summers of 2013-2017. The Icelandic oystercatcher population contains individuals that stay in Iceland year-round and individuals that migrate to mainland Europe in the non-breeding season, and feather isotope ratios provide a means of distinguishing between these migratory behaviours...

Mapping Africa’s biodiversity: more of the same is just not good enough

Harith Farooq, Josué Azevedo, Amadeu Soares, Alexandre Antonelli & Søren Faurby
Species distribution data are fundamental to the understanding of biodiversity patterns and processes. Yet, such data are strongly affected by sampling biases, mostly related to site accessibility. The understanding of these biases is therefore crucial in systematics, biogeography and conservation. Here we present a novel approach for quantifying sampling effort and its impact on biodiversity knowledge, focusing on Africa. In contrast to previous studies assessing sampling completeness (percentage of species recorded in relation to predicted),...

Data from: Pro-inflammatory immune response is linked to wintering habitat in a migratory shorebird

José Mª Abad-Gómez, Auxiliadora Villegas, Jorge S. Gutiérrez, Manuel Parejo, Juan G. Navedo, Juan M. Sánchez-Guzmán & Afonso Rocha
Migratory shorebirds (Charadrii) show a strong dichotomy in their breeding and wintering strategies: Arctic-breeding species typically spend the wintering season in marine habitats, while more southerly breeding species tend to do so in freshwater habitats where pathogens and parasites, particularly vector-borne blood parasites, are generally more abundant. Thus, it has been hypothesized that the former group may reduce their investment in immunity, but experimental data supporting this hypothesis are lacking. Moreover, whether this contrasting habitat...

Identification of scavenger receptors and thrombospondin type 1 repeat proteins potentially relevant for plastid recognition in Sacoglossa

Jenny Melo Clavijo, Silja Frankenbach, Cátia Fidalgo, Joao Serôdio, Alexander Donath, Angelika Preisfeld & Gregor Christa
Functional kleptoplasty is a photosymbiotic relationship, in which photosynthetically active chloroplasts serve as an intracellular symbiont for a heterotrophic host. Among Metazoa, functional kleptoplasty is only found in marine sea slugs belonging to the Sacoglossa and recently described in rhabdocoel worms. Although functional kleptoplasty has been intensively studied in Sacoglossa, the fundamentals of the specific recognition of the chloroplasts and their subsequent incorporation are unknown. The key to ensure the initiation of any symbiosis is...
