Agri‐Environmental Schemes (AES) have been proposed to mitigate the impact of agriculture on both taxonomic and functional biodiversity. However, a better knowledge of the mechanisms involved in the loss of agrobiodiversity is needed to implement efficient AES. An unbalanced effort on research towards arable lands compared to permanent crops, and o...

Farming impacts animal-mediated seed dispersal through mechanisms operating on at least two spatial scales. First, at the landscape scale, through habitat loss and land conversion to agriculture/livestock grazing, and second, at the farm scale, via a local intensification of agricultural practices. These two scales of farming impact seed dispersal...

The diets of the Barn Owl Tyto alba and the Short-eared Owl Asio flammeus have been extensively studied worldwide over the past few years, especially on the Iberian Peninsula. Nevertheless, very few studies have examined the diets and the trophic niche overlap in areas where these two raptor species occur in sympatry. As such, in this study we comp...

La biodiversidad de los ecosistemas está disminuyendo globalmente a un ritmo sin precedentes como consecuencia de la acción humana. Detectar a tiempo los factores que determinan la disminución de especies y/o declives poblacionales es uno de los mayores retos al que nos enfrentamos en el siglo XXI. Los humedales, al igual que otros tipos de ecosist...
Article
Research on seed-dispersal mutualisms has been highly unbalanced towards the plants, largely overlooking the fitness effects of fruit resources on frugivorous animals. Moreover, despite morphological mismatches like gape limitation may reduce the abundance of fruits that are actually accessible to a frugivore species, there is very little evidence...

Pesticides used in agriculture to prevent yield and economic loss are a threat for the natural heritage worldwide. Finding win-win solutions for pest control management in sustainable and profitable agriculture is a current yet elusive challenge for human societies. The main alternative to reduce pest damage in a sustainable manner consists in fost...

La alteración de los paisajes naturales y los cambios en el uso del suelo por agricultura y ganadería, son unos de los principales conductores del Cambio Global y de la pérdida de biodiversidad y de servicios ecosistémicos. En las últimas décadas la intensificación agrícola ha conducido, además, a una homogeneización y simplificación de los paisaje...
Article
One of the current challenges for applied ecologists is to understand how to manage/restore agroecosystems in a sustainable and cost‐effective way. The Intermediate Landscape Complexity Hypothesis (ILCH) predicts that the effectiveness of agri‐environmental measures (AES) on biodiversity and ecosystem services recovery is often largest in landscape...

Los pastos herbáceos de alta montaña mediterránea están constituidos por especies singulares, y representan una fuente de alimento para la ganadería extensiva durante los periodos de menor oferta forrajera (verano-otoño). La singularidad florística de estos hábitats, junto con su interés pastoral, justifican el estudio que presentamos. El objetivo...

Question
I´m looking for papers showing raw abundance data for different groups of animals, plants, and bacteria. I would be interested in studies on: mammals, birds, reptiles, amphibians, insects, fishes, annual plants and trees.
Any recommended paper will be of great use.
Thank you so much !
Question
We need a list of species associated with functional traits that allow us to characterize the functional diversity and its possible relationships with different phenological events of each group.
Thank you very much in advance !!
Question
I am working with taxonomic and functional diversity of weeds in olive orchard and I am trying to use the function RaoRel using package "Cati" for R. I am to calculate alpha, betha and gamma diversity in the framework of Rao Index with Jost correction. I got to run RaoRel function but I have some questions...
1. Sample = The community matrix of abundance (c x s) of the s species for the c local communities ("Sample" in function)
I have two scenarios, and from each one of them I want to get alpha diversity and betha diversity between each of them . However, one of them is sampled with 4 sampling points while the other is sampled with 2 sampling points. Would there be any way to equalize both samples so that they were balanced?
I know that alpha, beta and gamma diversity can be analyzed through (Lande 1996) weighted by the number of samples of each of the scenarios, but I do not know if this can be done in a package.
2. STRUCTURE = A data frame containing the name of the group to which samples belong see (de Bello et al, 2011) for more details
Could I work with a multitude of scenarios at the same moment thanks to this function?
What is the best way to apply it?
Thanks in advance ¡¡

Project
This project aims at filling the knowledge gap on the fitness consequences of plant-frugivore mutualisms for the animal partners (resource provisioning). We will test whether local fruit abundance affects the body condition of frugivore populations, focusing on a resident passerine as study species (the Sardinian Warbler Sylvia melanocephala). We are working in Mediterranean forest patches of the Guadalquivir Valley, where the abundance of fleshy fruits in the understorey vary hugely among patches due to differences in local management and successional stage.
