Allochrony is shaped by foraging niche segregation rather than adaptation to th...
Ventura, Francesco; Granadeiro, José P.; Catry, Paulo; Gjerdrum, Carina; De Pascalis, Federico; Viveiros, Filipe; Silva, Isamberto; Menezes, DiliaEcological segregation allows populations to reduce competition and coexist in sympatry. Using as model organisms two closely related gadfly petrels endemic to the Madeira archipelago and breeding with a two month allochrony, we investigated how movement and foraging preferences shape ecological segregation in sympatric species. We tested the hypothesis that the breeding allochrony is underpinned by foraging ni...

Monitoring of mercury in the mesopelagic domain of the Pacific and Atlantic oce...
Furtado, Ricardo; Granadeiro, José Pedro; Gatt, Marie Claire; Rounds, Rachel; Horikoshi, Kazuo; Paiva, Vítor H.; Menezes, Dilia; Pereira, EduardaGlobal mercury pollution has markedly and consistently grown over the past 70 years (although with regional variations in trends) and is a source of major concern. Mercury contamination is particularly prevalent in biota of the mesopelagic layers of the open ocean, but these realms are little studied, and we lack a large scale picture of contamination in living organisms of this region. The Bulwer's petrel Bulw...

Stone-stacking as a looming threat to rock-dwelling biodiversity
Rocha, Ricardo; Borges, Paulo A. V.; Cardoso, Pedro; Kusrini, Mirza D.; Martín-Esquivel, José L.; Menezes, Dilia; Ferreira, Mário Mota; Nunes, Sara F.This letter to the editor describes the surge of “photo-friendly” stacks of stones as an emerging tourism-associated threat to rock-dwelling biodiversity.
New data on the fruit flies (Drosophilidae) of Madeira archipelago with notes o...
Rego, Carla; Aguiar, António F.; Cravo, Délia; Boieiro, Mário; Silva, Isamberto; Castro, Catarina P.; Menezes, Dilia; Serrano, Artur R. M.The first findings of drosophilids from Desertas and Porto Santo islands (Madeira archipelago) are reported and the knowledge on the abundance and distribution of the endemic Drosophila madeirensis Monclús is updated. This Madeiran endemic was found associated with forest habitats, but was not exclusive of Laurisilva. Furthermore, the finding of widespread populations with moderate abundance indicates that pres...
Spatial distribution of Madeira Island Laurisilva endemic spiders (Arachnida: A...
Crespo, Luís C.; Boieiro, Mário; Cardoso, Pedro; Aguiar, Carlos A. S.; Amorim, Isabel R.; Barrinha, Carla; Borges, Paulo A. V.; Menezes, DiliaMadeira island presents a unique spider diversity with a high number of endemic species, many of which are still poorly known. A recent biodiversity survey on the terrestrial arthropods of the native forest, Laurisilva, provided a large set of standardized samples from various patches throughout the island. Out of the fifty two species recorded, approximately 33.3% are Madeiran endemics, many of which had not b...

Olivera, Paulo; Menezes, Dilia; Trout, Roger; Buckle, Alan; Geraldes, Pedro; Jesus, JoséThe Portuguese island of Selvagem Grande (Great Salvage) in Macaronesia is an important seabird breeding station in the eastern Atlantic. Significant populations of Cory’s shearwater Calonectris diomedea (Scopoli, 1769), Bulwer’s petrel Bulweria bulweria (Jardine & Selby, 1828) and little shearwater Puffinus assimilis baroli (Bonaparte, 1857) are present, and white-faced storm-petrel Pelagodroma marina (Latham,...
