- Depredation of Monteiro's Storm-petrel (Hydrobates monteiroi) Chicks by Madeiran Wall Lizard (Lacerta dugesii)Publication . Neves, Verónica C.; Nava, Cristina; Monteiro, Eva; Monteiro, Paulo R.; Bried, JoëlMonteiro’s Storm-petrel (Hydrobates monteiroi) is a small seabird endemic to the Azores archipelago, where it is known to breed only on two mammal-free islets. Total breeding numbers are between 250 and 300 pairs. During the 2015 breeding season on Praia Islet, six Madeiran wall lizards (Lacerta dugesii) were observed depredating a Monteiro’s Storm-petrel chick about to fledge. In August 2015, a freshly killed chick without its head and four larger dead chicks were found. Eight other chicks had disappeared from their nests since our previous visit in early July. In 2016, there was further evidence of suspected lizard depredation. Three chicks were found predated and dragged out of their nests, and an additional 22 chicks disappeared from their nests before fledging. In 2016, Monteiro’s Storm-petrel breeding success was only 26.8%, the lowest ever recorded. We suspect that some of the chick deaths and nest failures may be attributable to these introduced lizards. All chicks were found dragged out of their nests, a behavior that is not consistent with kills from aerial predators. Lizards were suspected because they are the only possible predator on land. Therefore, we recommend evaluating the impact of Madeiran wall lizards on the two Monteiro’s Storm-petrel main colonies: Praia and baixo islets.
- Standardised inventories of lepidopterans and odonates from Serra da Estrela Natural Park (Portugal) : setting the scene for mountain biodiversity monitoringPublication . Boieiro, Mário; Antunes, Sandra; Figueiredo, Hugo; Soares, Albano; Lopes, Ana; Monteiro, Eva; Garcia-Pereira, Patrícia; Rego, Carla; Conde, José; Borges, Paulo A. V.; Serrano, Artur R. M.BACKGROUND: Mountain insect biodiversity is unique, but is menaced by different drivers, particularly climate and land-use changes. In mainland Portugal, the highest mountain - Serra da Estrela - is one of the most important biodiversity hotspots, being classified as Natural Park since 1976. Many lepidopteran and odonate species, including rare and protected species, are known to occur in Serra da Estrela, but basic knowledge on their abundance, distribution and ecology is still lacking. Standardised sampling of these communities is crucial to provide valuable biological information to support short-term decision-making for conservation management, setting simultaneously the standards for mountain biodiversity monitoring aiming to tackle the effects of environmental change in the long-term. NEW INFORMATION: This study reports novel information on lepidopteran and odonate species diversity, distribution and abundance from Serra da Estrela Natural Park (Portugal). Seventy-two lepidopteran and 26 odonate species were sampled in this protected area, including the first findings of Apatura ilia (Denis & Schiffermüller, 1775), Macromia splendens (Pictet, 1843) and Vanessa virginiensis (Drury, 1773). New populations of Euphydrias aurinia (Rottemburg, 1775) and Oxygastra curtisii (Dale, 1834), protected species under the Habitats Directive, were found in this Natural Park and novel distribution and ecological data were collected for most species, including several rare species and subspecies [e.g. Aeshna juncea (Linnaeus, 1758), Coenonympha glycerion iphioides Staudinger, 1870, Cyaniris semiargus (Rottemburg, 1775) and Sympetrum flaveolum (Linnaeus, 1758)]. All data were collected using standardised sampling allowing its use as a baseline for biodiversity monitoring in Serra da Estrela.

- Standardised sampling of odonates (Odonata) in Serra da Estrela (Portugal) - 2013 and 2014Publication . Boieiro, Mário; Antunes, Sandra; Figueiredo, Hugo; Soares, Albano; Lopes, Ana; Monteiro, Eva; Pereira, Patrícia Garcia; Rego, Carla; Conde, José; Borges, Paulo A. V.; Serrano, Artur R. M.Mountain ecosystems are crucial for biodiversity conservation since they host high biodiversity. This study reports novel information on odonate species diversity, distribution and abundance from Serra da Estrela Natural Park (Portugal). Twenty six odonate species were sampled in this protected area, including the first finding of Macromia splendens (Pictet, 1843). New populations of Oxygastra curtisii (Dale, 1834), a protected species under the Habitats Directive, was found in this Natural Park and novel distribution and ecological data was collected for most species, including several rare species (e.g., Aeshna juncea (Linnaeus, 1758), Sympetrum flaveolum (Linnaeus, 1758)).
