Microbial and physicochemical parameters associated with Legionella contamination in hot water recirculation systems
Hot water recirculation systems (HWRS) in hotels and nursing homes, which are common in countries such as Spain, have been related to outbreaks of legionellosis. To establish the relationships of microbial and physicochemical ...
Trends in Urban Wild Meat Trade of Chelonians (Turtles and Tortoises) in the Peruvian Amazon
Culturally, chelonians are important sources of nutrition and income for rural and urban people in tropical rainforests, but urban trade can cause declines in wild populations. This study analyses the urban chelonian trade ...
Impact of hydrocarbon extraction on heavy metal concentrations in lowland paca (Cuniculus paca) from the Peruvian Amazon
Oil has been extracted from the Western Amazon since the 1920s, leading to severe environmental contamination due to frequent occurrence oil spills and the dumping of produced water. Local inhabitants, along with environmental ...
Evaluating biotic interactions in a hard and fragile ecosystem: xerophilous land snails and epilithic cryptogram communities in rocky outcrops
In biodiversity hotspots like rocky outcrops, species distribution is shaped by environmental factors at multiple scales, with microhabitat characteristics like substrate composition and shelter playing key roles. These ...
Prolonged drought constrains pine cone production but not its consumption
Seed production is vital for plant recruitment, shaped by tree traits, climate, and biotic pressures. Droughts can strongly affect reproductive processes, with cascading effects on squirrels. Their feeding behaviour responds ...
Efectes de la pastura sobre l’estat de conservació de les molleres pirinenques
Resum: Les molleres pirinenques, aiguamolls d’alta muntanya, han estat pasturades des d’antic. Actualment són freqüents les molleres amb símptomes de sobrepastura, sobretot per la freqüentació de ramats bovins. La sobrepastura ...
Effect of introduction pathways on the invasion success of non‑native plants along environmental gradients
Our understanding on the role of introduction pathways on plant invasions is incomplete because their interaction with other factors remains poorly studied. We contributed to filling this knowledge gap, by analysing temporal ...
Whole-stream wastewater addition stimulates the green food web pathway but does not affect food chain length
Most rivers in developed regions receive tertiary-treated effluents from wastewater treatment plants that still contain a complex mixture of pollutants, but their combined effects on food webs are poorly understood. We had ...
The arachnofauna of the Valencian coastal dunes (eastern Iberian Peninsula): checklist and new records for Spain and Europe
We present here the results of the first semi-quantitative survey of arachnids conducted on coastal dunes of Spain. We used the optimized COBRA protocol to sample two localities along the Valencian coast. We collected 2886 ...
Plant traits poorly predict winner and loser shrub species in a warming tundra biome
<p>Climate change is leading to species redistributions. In the tundra biome,</p><p>shrubs are generally expanding, but not all tundra shrub species will benefit</p><p>from warming. Winner and loser species, and the ...
Growth and phenology of three dwarf shrub species in a six-year soil warming experiment at the alpine treeline
Global warming can have substantial impacts on the phenological and growth patterns of alpine and Arctic species, resulting in shifts in plant community composition and ecosystem dynamics. We evaluated the effects of a ...
Novel Integration of Forage Cereal-Legume Mixtures in Conservation Agriculture Enhances Weed Control and Barley Productivity in Moroccan Drylands
Background: To our knowledge, this is the first study quantitatively investigating the mixed forage integration into dryland conservation agriculture (CA) systems in the Mediterranean region. Weed management under CA is ...
Xylem anatomical and growth responses of the dwarf shrub <em>Vaccinium myrtillus</em> to CO<sub>2</sub> enrichment and soil warming at treeline.
Plant growth responses to environmental changes may be linked to xylem anatomical adjustments. The study of such links is essential for improving our understanding of plant functioning under global change. We investigated ...
Sea urchin holobionts: microbiome variation across species, compartments and locations in Paracentrotus lividus and Arbacia lixula
Understanding holobiont dynamics is essential for unraveling the complex interactions between marine hosts and their microbiota. Sea urchins play pivotal roles in shaping benthic ecosystems, yet the functional roles of ...
Using Scenarios for Reducing Uncertainties in Biodiversity Conservation: From Global Targets to European Steppes
Scenario analysis allows assessing how complex socio-ecological systems might respond to different policy pathways. We usedan expert-based participatory approach to explore how four different European socio-ecological ...
Fall and Rise of a Threatened Raptor: Unraveling Long-Term Population Dynamics with Spatially Explicit Integrated Models.
Population dynamics are governed by the so-called four BIDE processes: birth, immigration, death, and emigration. However, most population models fail to explicitly consider all four processes, which may hinder a comprehensive ...
Biodiversity of Marine Mollusk Assemblages from Two Contrasted Algal Habitats in the Mediterranean Sea (Tossa de Mar, Costa Brava, NE Spain)
The malacological faunae of two algal habitats with different lighting conditions—a sciophilous wall and a photophilous one—both located in Tossa de Mar (Costa Brava, Girona, NE Spain), have been studied to examine the ...
Human evolution: Stature variation in the Neolithic
he Neolithic transition towards agriculture and animal husbandry is often associated with declining nutrition and health, which led to shorter human stature. A new study reveals that the reduction in height was modest and ...
Postharvesting population dynamics of the South American sea lion (Otaria byronia) in the southwestern Atlantic
Many pinniped populations precipitously declined during the 19th and 20th centuries due to overharvesting. In Uruguay, the South American sea lion (SASL) was harvested until 1986. Birth rates in two nearby breeding colonies ...
Diet-to-female and female-to-pup isotopic discrimination in South American sea lions
Rationale: The use of accurate, species-specific diet-tissue discrimination factors is a critical requirement when applying stable isotope mixing models to predict consumer diet composition. Thus, diet-to-female and ...
