Plant invasions are context-dependent: Multiscale effects of climate, human activity and habitat
ABSTRACT Aim Understanding the conditions that promote biological invasions is a critical step to developing successful management strategies. However, the level of invasion is affected by complex interactions among ...
Implications of using different metrics for niche analysis in ecological communities
Explaining the mechanisms driving niche partitioning among species is of great importance in ecology. Unlike the fundamental niche, a species' realised niche can only be measured in situ, as a result of biotic and abiotic ...
DNA metabarcoding unveils niche overlapping and competition among Caribbean sea urchins
Detailed information of trophic interactions among consumer-resources in food webs is usually limited due to the lack of accurate identification of eaten food resources. The use of DNA-metabarcoding has been proven useful ...
Diel pattern of Chironomids drift in the Llobregat river
Drift has recived considerable attention in recent times as a method to collect chironomid pupal exuviae (COFFMAN, 1973; LAVILLE, 1979, 1981) for taxonomie as well as water pollution studies (WILSON, 1977).
Respiration regimes in rivers: Partitioning source-specific respiration from metabolism time series
Respiration in streams is controlled by the timing, magnitude, and quality of organic matter (OM) inputs from internal primary production and external fluxes. Here, we estimated the contribution of different OM sources to ...
Los rechazos minerales procedentes de la explotación de calizas: limitaciones para su uso como sustrato para la restauración ecológica
Este artículo se centra en la problemática de los sustratos de restauración y presenta los resultados obtenidos del estudio con materiales que se aplican en la restauración en 6 explotaciones de piedra caliza, localizadas ...
Fin whale (Balaenoptera physalus) mitogenomics: A cautionary tale of defining sub-species from mitochondrial sequence monophyly
The advent of massive parallel sequencing technologies has resulted in an increase of studies based upon complete mitochondrial genome DNA sequences that revisit the taxonomic status within and among species. Spatially ...
Drought effects on resource quality in a Mediterranean stream: fatty acids and sterols as indicators
Seasonal droughts in Mediterranean streams shape their physical, chemical, and biological characteristics. Thus, droughts have the potential to alter resources at the base of the food web, which in headwater streams are ...

Four years of experimental warming do not modify the interaction between subalpine shrub species
Climate warming can lead to changes in alpine plant species interactions through modifications in environmental conditions, which may ultimately cause drastic changes in plant communities. We explored the effects of 4 years ...
Phenotyping genotypic performance under multistress conditions: Mediterranean wheat as a case study
Context or problem: While crop breeding represents a key factor in terms of effectiveness and affordability in the adaptation of agriculture to stress conditions, phenotyping is perceived as a major bottleneck to achieving ...
Fecal pellets collection as a method for assessing egesta of the marine cave-dwelling mysid Hemimysis speluncula
Egesta of a cave-dwelling mysid (Hemimysis speluncola Ledoyer, 1963) was studied in a submarine cave of Medes Islands, NW Mediterranean by in situ fecal pellet collecting. Fecal pellet production and gut fullness of mysids ...

Management and ecology of the wedge clam (Donax trunculus) in the NW Mediterranean Sea: The case of Ebro Delta (NE Spain)
The wedge clam (Donax trunculus) is one of the most prized clam species fished in the EU. Clam fisheries have experienced a dramatic decline during the last decades on Spanish coasts resulting in the progressive closure ...

Towards non-invasive methods in measuring fish welfare: the measurement of cortisol concentrations in fish skin mucus as a biomarker of habitat quality
Cortisol levels in fish skin mucus have shown to be good stress indicators in farm fish exposed to different stressors. Its applicability in free-ranging animals subject to long-term environmental stressors though remains ...
