Importància dels guarets ambientals com a font d'insectes per a la conservació del sisó (Tetrax tetrax) i altres ocells esteparis en els secans cerealístics
Els sistemes agrícoles d'Europa occidental (entre els quals els secans cerealístics, amb una rica comunitat d'ocells esteparis greument amenaçada) han sofert una important intensificació que ha comportant fortes disminucions ...
Arm-less mitochondrial tRNAs conserved for over 30 millions of years in spiders
Background: In recent years, Next Generation Sequencing (NGS) has accelerated the generation of full mitogenomes, providing abundant material for studying different aspects of molecular evolution. Some mitogenomes have ...
Primer C-Hydrochange workshop sobre métodos y técnicas de medida de flujos de CO2 y CH4 en lagos y embalses
La distribución de la reservas de carbono (C) entre compartimentos del Sistema Tierra constituye uno de los principales temasde estudio de la biogeoquímica moderna. Lagos y embalses des-empeñan un papel importante en los ...
Evolutionary Genetics of Microbial Symbiosis
Symbiosis is the living together of dissimilar organisms [1,2]. As such, symbiotic relationships can range from antagonist (parasitic) to mutualistic and can vary along this continuum within and between species in space ...
A global perspective on the trophic geography of sharks
Sharks are a diverse group of mobile predators that forage across varied spatial scales and have the potential to influence food web dynamics. The ecological consequences of recent declines in shark biomass may extend ...
How does optimal prey abundance shape space use by a territorial raptor?
Understanding predator-prey interactions is important to determine the inter-relationships between species. Optimal foraging theory states that predators balance out energy expended with the energy gained from their prey. ...
Diet composition of a declining steppe bird the little bustard (Tetrax tetrax) in relation to farming practices
Foraging strategies and diet selection play an essential role in individual survival and reproductive success. The study of feeding ecology becomes crucial when it concerns endangered species such as the Little Bustard ...
Stable isotope ratios indicate trophic niche overlap in three sympatric delphinid species in the Eastern Ionian Sea
Studying the sympatric ecology of closely related marine top predator species is of interest both from an ecological and conservation standpoint, because it provides insights into ecosystem functioning, how such species ...
Wheat mixtures as an effective option for weed management in organic farming
In organic cereal cropping systems, crop diversification has emerged as an environmentally friendly strategy for weed management. However, the role of crop mixtures in weed regulation, particularly in Mediterranean conditions, ...
Influence of reproduction on stable isotope ratios: nitrogen and carbon isotope discrimination between mothers, foetuses, and milk in the fin whale, a capital breeder
In mammals, the influence of gestation and lactation on the tissue stable-isotope ratios of females, fetuses, and milk remains poorly understood. Here we investigate the incidence of these events on δ13C and δ15N values ...
Aggregation of organically managed fields promotes aphid parasitism in cereal crops under Mediterranean conditions
Context: Maintaining a balance between semi-natural habitats and arable land is not always feasible for farmers. The promotion of biological control agents can be addressed through management at farm or field level, and/or ...
Dry habitats sustain high CO2 emissions from temporary ponds across seasons
Despite the increasing understanding of the magnitude and drivers of carbon gas emissions from inland waters, the relevance of water fluctuation and associated drying on their dynamics is rarely addressed. Here, we quantified ...
The Vitruvian spider: segmenting and integrating over different body parts to describe eco-phenotypic variation
Understanding what drives the existing phenotypic variability has been a major topic of interest for biologists for generations. However, the study of the phenotype may not be straightforward. Indeed, organisms may be ...
Updated catalogue and taxonomical notes on the Old-World scorpion genus Buthus Leach, 1815 (Scorpiones, Buthidae).
Since the publication of the ground-breaking 'Catalogue of the scorpions of the world (1758-1998)' (Fet et al. 2000) the number of species in the scorpion genus Buthus Leach, 1815 has increased 10-fold, and this genus is ...
How does heat stress affect sponge microbiomes? Structure and resilience of microbial communities of marine sponges from different habitats
Introduction: Sponges are key components of marine benthic communities, providing many ecosystem functions and establishing close relationships with microorganisms, conforming the holobiont. These symbiotic microbiotas ...
Non-breeding distribution and at-sea activity patterns of the smallest European seabird, the European Storm Petrel (Hydrobates pelagicus)
Determining the non-breeding distribution and activity patterns of migratory animals is essential to understand the trade-offs across breeding, moulting and migratory periods and to evaluate the differential levels of ...
Impact of climate change on spider species distribution along the La Plata River basin, southern South America: projecting future range shifts for the genus Stenoterommata (Araneae, Mygalomorphae, Nemesiidae)
The La Plata River basin comprises the second largest fluvial system in South America and includes the southernmost remains of the 'Atlantic Forest Biodiversity Hotspot'. We used species distribution modelling to evaluate ...
Revealing hidden diversity and cryptic speciation in Antarctic marine gastropods (Heterobranchia: Cephalaspidea)
Recent studies have revealed significant hidden diversity and a high incidence of cryptic speciation in Antarctic marine gastropods. Originally, philinoid cephalaspideans in the Southern Ocean were classified within the ...
A critical assessement of Conservation Agriculture among smallholders in the Mediterranean region: Adoption pathways inspired by agroecological principles
Conservation agriculture (CA) is the key agricultural soil management approach for Mediterranean rainfed systems facing extreme droughts and soil degradation. Yet, CA uptake and applicability is still marginal and disputed ...
Concentrations of bisphenol and phthalate ester compounds in the muscle of Mediterranean striped dolphins (Stenella coeruleoalba)
Bisphenols (BPs) and phthalate esters (PAEs) are important compounds for the plastics industry, also called “everywhere chemicals” due to their ubiquity in daily use products. Both chemical groups are well-known environmental ...
