Moss cover and browsing scores as sustainability indicators of mountain ungulate populations in Mediterranean environments
Biodiversity and Conservation - Tập 31 - Trang 2741-2761 - 2022
Here, we aimed to define ecological indicators of environmental change for monitoring the effect of a reintroduced species, the Iberian ibex (Capra pyrenaica), over the vegetation of a natural protected area with contrasting habitats. This species was reintroduced 30 years ago in the Sierra de Guadarrama National Park, Spain, and its population has since grown exponentially, reaching high densitie......
Persistence through tough times: fixed and shifting refuges in threatened species conservation
Biodiversity and Conservation - Tập 28 - Trang 1303-1330 - 2019
It may be possible to avert threatened species declines by protecting refuges that promote species persistence during times of stress. To do this, we need to know where refuges are located, and when and which management actions are required to preserve, enhance or replicate them. Here we use a niche-based perspective to characterise refuges that are either fixed or shifting in location over ecolog......
Global effects of land use intensity on the impoverishment of insect herbivore assemblages
Biodiversity and Conservation - Tập 24 - Trang 271-285 - 2014
The modification of pristine wildlife habitats by land use is a worldwide cause of species extinction, as most native species cannot persist at high levels of human land use intensity. In this study, we gathered 90 lists of local interactions between herbivorous insects and their host plants to investigate the effects of land use intensity on the species richness and taxonomic diversity of insect ......
Morphological grouping of Mexican butterfliesin relation to habitat association
Biodiversity and Conservation - Tập 7 - Trang 927-944 - 1998
Current rates of destruction of natural ecosystems call for rapid and efficient ways of assessing the successional state or degree of perturbation, and of monitoring management efforts. In this paper we propose that butterfly species, grouped by morphological and ethological traits, can be used for these purposes. The groups, each composed of species from many taxa, appear to be strongly correlate......
Linking local ecological knowledge and habitat modelling to predict absolute species abundance on large scales
Biodiversity and Conservation - Tập 19 - Trang 1443-1454 - 2009
Assessing the spatial structure of abundance of a species is a basic requirement to carry out adequate conservation strategies. However, existing attempts to predict species abundance, particularly in absolute units and on large scales, are scarce and have led to weak results. In this work we present a scheme to obtain, in an affordable way, a predictive model of absolute animal abundance on large......
Protecting the Cerrado: where should we direct efforts for the conservation of bat-plant interactions?
Biodiversity and Conservation - Tập 28 - Trang 2765-2779 - 2019
Cerrado is a biodiversity hotspot composed of a vegetation mosaic landscape ranging from grasslands to forests. It holds a high endemicity of plants and vertebrate species suffering from high habitat destruction rates. We aimed at characterizing the mutualistic interactions between bats and the plant species present in their diet in the different habitats of the Cerrado to determine which habitats......
The method of conserving herbaceous grassland specialists through silvicultural activities under deer browsing pressure
Biodiversity and Conservation - Tập 27 Số 11 - Trang 2919-2930 - 2018
Early-successional herbs such as grassland specialists in semi-natural grasslands are decreasing because the intensity of using semi-natural grassland is decreasing for the decrease of human population or the usage of fossil fuel as energy source. Deer browsing also decreases grassland specialists. Silvicultural activities such as clearcutting, mowing of understory vegetation, and deer countermeas......
Conservation by trans-border cooperation: population genetic structure and diversity of geoffroy’s bat (Myotis emarginatus) at its north-western european range edge
Biodiversity and Conservation - Tập 31 - Trang 925-948 - 2022
In the European Union, all bat species are strictly protected and member states must ensure their conservation. However, if populations are genetically structured, conservation units that correspond to whole countries may be too large, putting small populations with specific conservation requirements at risk. Geoffroy’s bat (Myotis emarginatus) has undergone well-documented declines at its north-w......
Synergistic effect of habitat loss and chronic anthropogenic disturbances on ant species richness
Biodiversity and Conservation - - Trang 1-15 - 2023
Habitat loss is an important factor in global biodiversity loss, but categorizing human-modified landscapes as fragments of natural or anthropogenic habitats may underestimate our impact on biodiversity since most natural fragments suffer from chronic anthropogenic disturbances. Here, we tested the synergistic effect between habitat loss and chronic anthropogenic disturbances on ant communities of......
Comparisons of microsatellite variability and population genetic structure of two endangered wild rice species, Oryza rufipogon and O. officinalis, and their conservation implications
Biodiversity and Conservation - Tập 14 - Trang 1663-1679 - 2005
Conserving endangered wild rice species requires a thorough understanding of their population genetic structure and appropriate approaches. We applied six and seven microsatellite loci to study the genetic structure of six populations throughout the range of Chinese Oryza rufipogon and Oryza officinalis, respectively. The results showed that O. rufipogon possesses higher levels of genetic diversit......
