We review the ecological rationale behind potential compatibility between top predators and biodiversity conservation, examine their effectiveness as surrogate species. Evidence suggests that promote species richness or are spatio-temporally associated with it for six causative noncausative reasons: resource facilitation, trophic cascades, dependence on ecosystem productivity, sensitivity to dysfunctions, selection of heterogeneous sites links multiple components. Therefore,...
Black kite nest decorations are honest signals of individual and territory quality.
Abstract: Invasions of non‐native species are one the major causes losses native species. In some cases, however, non‐natives may also have positive effects on We investigated potential facilitative North American red swamp crayfish (Procambarus clarkii) community predators in southwestern Spain. To do so, we examined diets area and their population trends since introduction crayfish. Most predator consumed crayfish, which sometimes occurred over 50% diet samples. Moreover, abundance preying...
Illegal trade constitutes a major threat for variety of wildlife. A criminology framework has been recently applied to parrot poaching in Mexico, suggesting an opportunistic crime which the most abundant and accessible species, not rare or highly priced were poached more often. We analyzed this information, together with additional long-term data (1981–2005) on both legal illegal 22 Mexican species (n = 31,019 individuals), using multivariate statistics hypothesis-testing approaches. Our...
Addressing the challenge of photovoltaic growth: Integrating multiple objectives towards sustainable green energy development,
Abstract Understanding the distribution of biodiversity across Earth is one most challenging questions in biology. Much research has been directed at explaining species latitudinal pattern showing that communities are richer tropical areas; however, despite decades research, a general consensus not yet emerged. In addition, global patterns being rapidly altered by human activities. Here, we aim to describe large‐scale richness and diversity terrestrial vertebrate scavenger...
Factors affecting individual variation in between-year territory change and dispersal distance were measured a long-term study of Black Kites (Milvus migrans) living an area ∼100000 ha around Doñana National Park southern Spain. Adult birds (N = 210) fledglings 3061) individually marked, breeding monitored annually during 1989–1996 to detect banded individuals. Of these 3271 birds, 652 resighted, 164 them sexed through copulatory behavior. Nests checked monitor performance. Frequencies...
We examined the nest site selection, breeding density and success in bearded vulture Gypaetus barbatus relation to physiography, climate, land-use degree of human disturbance. The study area was Pyrenean Cordillera, Spain, where largest European population this species occurs. univariate analyses Generalized Linear Models were employed. correctly classified 78% cliffs analysed (occupied by vultures, selected at random). probability occupation a cliff vultures directly related ruggedness...
Natal dispersal is of central interest when determining demography and genetic structure populations managing endangered species with fragmented distributions. However, methodological limitations linked to spatial temporal constraints have prevented studies natal in long-lived birds. Moreover, the consequences mainly been related first breeding attempt rather than lifetime reproductive success. We studied causes fitness a population Black Kites at Doñana National Park (southern Spain). From...
European pseudo‐steppes have suffered from extensive changes in agricultural practices during the past decades with disappearance of field margins and fallow systems increase biocide treatments. The negative effect on wildlife has led to adoption by Union policies more compatible environmental conservation, but decisions about optimal land use are difficult make because lack information. We studied habitat Lesser Kestrel ( Falco naumanni ), a globally vulnerable species, Spanish...
Bearded vulture populations in the Western Palearctic have experienced a severe decline during last two centuries that has led to near extinction of species Europe. In this study we analyse sequence variation at mitochondrial control region throughout range infer its recent evolutionary history and evaluate current genetic status species. This became possible through extensive use museum specimens now extinct. Phylogenetic analysis revealed existence divergent lineages, lineage A occurring...
The selection of foraging habitats by nine radio-tagged adult lesser kestrels (Falco naumanni) breeding in one colony southern Spain, was studied 1989 and 1990. Despite individual differences the feeding habitat, there a general tendency for grassland to be used more, sunflower woodlots less, than expected their availability. relatively higher food availability (measured as number hovering bouts catch prey) grasslands cereals would explain kestrels'preference these habitats. Since 1950s,...
Habitat selection models, such as the ideal free, despotic, site-dependent, and conspecific cuing are of great importance to behavioral ecologists given their capability predict habitat distributions link individual behavior population processes. However, there have been relatively few field tests predictions. We tested 4 models by studying process sequential settlement on territory in 2 distant populations a migratory raptor, black kite Milvus migrans. Results were mainly consistent with...
Abstract The development of conservation strategies to protect viable populations scavenging birds requires the existence adequate and safe food supplies in wild. Early reports on Andean condors Vultur gryphus diet recorded guanacos rheas, dominant herbivores since Pleistocene, as their main Patagonia. However, past century, guanaco rhea have notably decreased a consequence introduced livestock, other exotic mammals colonized region. We study spatial temporal variation condors' determine...
Abstract Understanding the factors underlying species coexistence is a major focus in community ecology. When dealing with competition between native and exotic species, competitive exclusion of ‘weaker’ can have consequences for biodiversity conservation. We examined interspecific interactions during foraging black vultures Coragyps atratus Andean condors Vultur gryphus Southern Argentina. Previous studies suggest facilitatory them. However, most parts their distribution ranges, these did...
