Sin duda, uno de los principales desafíos globales que afronta actualmente la humanidad es la conservación de la diversidad biológica. Sin ella, la especie humana no podrá sobrevivir en este planeta. Por esta razón, y en el actual contexto de degradación creciente de los ecosistemas y pérdida masiva de especies, es urgente la adopción de medidas qu...
Unintentional mortality of endangered carnivores due to non-selective trapping is important for conservation and warrants urgent attention. Currently, non-selective traps are being approved and used based on trap selectivity tests conducted according to International Organization for Standardization (ISO) guidelines. We review these guidelines and...
Illegal killing/taking of birds is a growing concern across the Mediterranean. However, there are few quantitative data on the species and countries involved. We assessed numbers of individual birds of each species killed/taken illegally in each Mediterranean country per year, using a diverse range of data sources and incorporating expert knowledge...
The avian genus Saxicola is distributed throughout Africa, Asia, Europe and various islands across Oceania. Despite the fact that the group has great potential as a model to test evolutionary hypotheses due to the extensive variability in life history patterns recorded between and within species, the phylogenetic relationships among species and sub...

Habitat-suitability modelling is being increasingly used as a tool for conservation biology. Although studies at large spatial scales are more appropriate for reserve design and management, there is a scarcity of published work on local, high-resolution applications of such models. In this work we develop high-resolution habitat models (1 ha) and s...
The reed bunting is one of the passerine species having the most scanty breeding
populations in the Iberian peninsula.Two subspecies breed in Spain; one of them
is endemic to the Iberian peninsula, the western Iberian reed bunting Emberiza
schoeniclus lusitanica, and the other only breeds in Spain and Southern France,
the eastern Iberian reed bunti...
El Gavilán Común está representado en la Macaronesia por una subespecie endémica de Canarias y de Madeira. Al ser un ave eminentemente forestal sólo se distribuye por las islas centrales y occidentales del archipiélago canario. Aunque se desconoce su tendencia, su pequeña población, estimada hace varios años en unas 170 parejas, hace que se califiq...
The aim of this study is to offer data for sexing juveniles and ageing Canary Islands Stonechats Saxicola dacotiae, an endemic and endangered bird, using data on wing measurements, moult, wing-formula and the inside colour of the upper mandible of wild-caught birds which were examined alive and then released. From January 2001 to July 2002, 92 indi...

E l Aguilucho Lagunero Occidental (Circus aeruginosus) está incluido en el Catálogo Nacional de Especies Amenazadas como "De interés especial" (B.O.E. 1990), y en el Catálogo Regional de Especies Amenazadas de la Comunidad de Madrid (B.O.C.M. 1992) como "Sensible a la alteración de su hábitat". En la reciente revisión del Libro Rojo la especie no s...
We have studied the migration routes and phenology of the Aquatic Warbler Acrocephalus paludicola throughout Spain by means of ringing and published observation data. The species' migration routes between breeding and winter quarters, both in spring and autumn, regularly take place through Spain. In the present study, two main coastal routes are de...
L a Cigüeña Blanca (Ciconia ciconia) está considerada como especie "No amenazada" en el ámbito mundial y como "Vulnerable" en la Unión Europea y en España (B.O.E. 1990; Blanco y González 1992; BirdLife International 2000). Sin embargo, la tendencia poblacional de la especie en los últimos años en España es positiva y esto hará que no aparezca por p...
43 págs. En este trabajo se recopila la bibliografía sobre ornitología española y de ambientes mediterráneos recogida en las siguientes publicaciones: Alauda (1998-1999); American Naturalist (1999); Animal Behaviour (1999); Ardea (1998-1999); Atlantic Seabirds (1999); Auk (1999); Avocetta (1998); Behavioral Ecology (1999); Behavioral Ecology and So...
We analysed whether patterns of microhabitat use by Blue Tits Parus caeruleus, Great Tits Parus major and Crested Tits Parus cristatus inhabiting a mixed forest consistently matched the patterns of food availability experienced by foraging birds during spring-summer. The use of five microhabitats by each bird species (the foliage of three tree spec...
The foraging behaviour of Blue Tit Parus caeruleus was studied in detail during the postbreeding period, and in this period they used Gum Cistus capsules quite intensively. We found arthropods in 57% of the examined capsules. The use of the capsules of this shrub demonstrates once again how ably Blue Tits cue in on localized plentiful but temporary...
104 E l Avión Común (Delichon urbica) es una especie de presen-cia estival que nidifica en casi todo el Paleártico (Hagemeijer y Blair 1997). En España nidifica práctica-mente en todas las comarcas excepto en Canarias, siendo más abundante en la parte suroeste de la Península (SEO/BirdLife 1997). En Madrid se encuentra distribuida por toda la Comun...
Habitat selection and adjustment of diurnal activity rhythm are two strategies that ectothermal organisms use in order to avoid unfavourable environmental conditions. Nevertheless, these patterns are variable in time, and differences in physiological requirements or wheather changes can produce different responses in the population. In this paper w...
Los estudios de selección de recursos por parte de los animales (ya sean estos recursos alimento, hábitats, lugares de nidificación, etc.) se han mostrado fundamentales en los estudios zoológicos, tanto teóricos como aplicados (Hess & Swartz, 1940; Holmes & Robinson, 1981; Virgós et al., 1993). Para cuantificar el grado de selección existen una gra...
The Spanish Ornithological Society (SEO/BirdLife) is a non-profit making organization working for the conservation of biodiversity through the conservation of birds and their habitats. SEO/BirdLife is the Spanish representative of BirdLife International, a global partnership of organizations working for nature conservation in over 100 countries. SE...

In the sense of the Aichi biodiversity target n°14
If so, why is it not as well known among administrations and citizens? Both threats have the same origin, emission of CO2 into the atmosphere by humans and both will have a major impact on biodiversity. However, acidification of the oceans is much less known. Why? Is acidification of the oceans considered to be less severe for biodiversity?
