Worldwide pollinator declines are a major problem for agricultural production. However, understanding how landscape characteristics and local management influence crop production through its pollinators is still a challenge. The carob tree (Ceratonia siliqua) is a pollinator-dependent Mediterranean crop of high economic importance in food and pharm...

Worldwide pollinator declines are a major problem for agricultural production. However, understanding how landscape characteristics and local management influence crop production through its pollinators is still a challenge. By sampling 20 orchards in Mallorca island (Spain), we evaluated how the landscape (habitat loss) and orchard local managemen...

Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity of terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects of cattle-grazing intensification on dung...

Traits are key for understanding the environmental responses and ecological roles of organisms. Trait approaches to functional ecology are well established for plants, whereas consistent frameworks for animal groups are less developed. Here we suggest a framework for the study of the functional ecology of animals from a trait‐based response–effect...

Aim Aridity gradients are of great interest for understanding the responses of biodiversity to water availability and water stress. However, little is known about the responses of many animal groups, which are crucial for assessing the effects of climate change. Here, we study the effects of aridity on dung beetle communities, a group with well‐kno...

In recent years, the popularity of rock-climbing has grown tremendously, setting an increasing pressure on cliff habitats. Climbing may be particularly harmful in the Mediterranean biome due to its appropriate environmental conditions for climbing. A few studies have identified the effect of climbing on plant diversity at a small-scale (namely loca...

The relationship between biodiversity and ecosystem functioning is often assessed through trait diversity. However, the relationship between traits and functions is typically assumed but seldom tested. We analyze the relationship between dung beetle traits and three ecological functions: dung removal, dung burial, and seedling emergence. We set up...

La biodiversidad cambia en el espacio-tiempo generando gradientes complejos. Estos gradientes afectan la estructura de las comunidades creando dos posibles patrones de recambio espacial, reemplazo o anidamiento. Existen pocos estudios que busquen analizar los cambios de la diversidad a lo largo de gradientes ambientales en la región Caribe de Colom...

Background Assemblage responses to environmental gradients are key to understand the general principles behind the assembly and functioning of communities. The spatially and temporally uneven distribution of water availability in drylands creates strong aridity gradients. While the effects of spatial variations of aridity are relatively well known,...

Definitions and summary values of environmental variables used. Table S1. Summary of grouped variables used (variables used in the final analyses have been marked with a tick mark ✓). Table S2. Localization (municipality and coordinates), altitude and amount of dung of each replicate and site sampled. Dung availability variables (cow dung and other...

Dung beetle abundance per year (2013 and 2014) and season (wet and dry) along a transect from the Sahara desert to the semiarid Mediterranean coast (see map in Figure 1). Table S3. Names of species are grouped by subfamily. Totals per site (i.e. community) are given for each subfamily.

Supplementary results. Table S4. Species with significant Indicator Values (IndVal, De Caceres & Legendre, 2009) per year (2013 and 2014) and season (wet and dry). Table S5. Summary of the GLRs evaluating the effects of the extracted PLS components on species richness and log abundance for the wet and dry seasons. Figure S1. Variation partitioning...

Authors give new data on Histeridae of Morocco and make a synthesis of the knowledge on this group in Oriental region. Saprinus apteli Chobaut is new for Morocco and Acritus nigricornis (Hoffmann) and Hypocacculus spretulus (Erichson) are new for the Oriental region.

En este capítulo revisamos algunos aspectos de esta “crisis de la Taxonomía”, identificando puntos críticos de la misma. Para ello, primero definimos qué es la Taxonomía, con una breve descripción de su desarrollo histórico. Además, identificamos quién la lleva a cabo, así como en qué grado son importantes unas u otras aproximaciones a esta discipl...

Semi-natural meadows host a great number of species coexisting at fine spatial scales. Different assembly mechanisms, related to differences in functional traits between species, can influence such coexistence. Coexisting species could be either functionally dissimilar to occupy different niches (‘divergence’) or functionally similar due to exclusi...
