Seabirds and the circulation of Lyme borreliosis bacteria in the North Pacific
Seabirds act as natural reservoirs to Lyme borreliosis spirochetes and may play a significant role in the global circulation of these pathogens. While Borrelia burgdorferi sensu lato (Bbsl) has been shown to occur in ticks ...
Settling velocity distribution of microalgal biomass from urban wastewater high rate algal ponds
The aim of this study was to evaluate the settling velocity distribution of microalgal biomass with and without flocculant (Tanfloc SG). Microalgal biomass was obtained from two experimental wastewater treatment high rate ...
A novel remote sensing approach for prediction of maize yield under different conditions of nitrogen fertilization
Maize crop production is constrained worldwide by nitrogen (N) availability and particularly in poor tropical and subtropical soils. The development of affordable high-throughput crop monitoring and phenotyping techniques ...
Changes in the foraging strategy of female South American sea lions (Carnivora: Pinnipedia) after parturition.
This study tests the hypothesis that female South American sea lions shift from off-shore, pelagic prey to coastal, benthic prey after parturition in order to reduce the foraging trip duration and hence the time pups remain ...
Two new records of Alloxysta (Hymenoptera: Cynipoidea: Figitidae: Charipinae) from Colombia
The Charipinae from Colombia has been recently studied. Nine Charipinae species are known to be present in this country: Alloxysta arcuata (Kieffer, 1902), Alloxysta castanea (Hartig, 1841), Alloxysta consobrina (Zetterstedt, ...

<span style="color:rgb( 33 , 33 , 33 )">Rewinding the invasion history of monk parakeets in Barcelona city: 1976-2022</span>
Rewinding the invasion history of monk parakeets in Barcelona city: 1976-2022. Predicting the future abundance and distribution of introduced alien species is crucial to mitigate their impact on ecosystems, but this has ...
Phothosharing websites may improve Hemiptera biodiversity knowledge and conservation
Internet photosharing websites is a very recent and powerful tool for the study of biodiversity, and a meeting point of general public fond of nature and professional naturalists. The article discusses when an uploaded ...
Estudios sobre la vegetacion del estado de Parana (Brasil meridional)
BOLOS, O. DE, A.C. CERVI & G. HATSCHBACH (1991). Estudios sobre la vegetación del estado de Paraná (Brasil meridional). Collect. Bot. (Barcelona) 20: 79-182. Aportación al conocimiento de la vegetación del estado de Paraná ...
Seasonal variation in AMF colonisation, soil and plant nutrient content in gypsum specialist and generalist species growing in P‑poor soils
Aims: Gypsum soils are P-limited atypical soils that harbour a rich endemic flora. These singular soils are usually found in drylands, where plant activity and soil nutrient availability are seasonal. No previous studies ...
Effect of environmental enrichment on the body shape of the pumpkinseed
How the morphology of captive-reared fish is affected by structural enrichment in their rearing tanks is not well understood. Some studies have suggested that deficiencies in rearing environments could produce inappropriate ...
Hydrological evidence for a North Atlantic oscillation during the Little Ice Age outside its range observed since 1850.
An annual-resolved precipitation reconstruction for the last 800 yr in Southern Spain has been performed using stable carbon isotope (δ13C) of Pinus nigra tree rings. The reconstruction exhibits high- to low-frequency ...
Foliar photochemical processes and carbon metabolism under favourable and adverse winter conditions in a Mediterranean mixed forest, Catalonia (Spain)
Evergreen trees in the Mediterranean region must cope with a wide range of environmental stresses from summer drought to winter cold. The mildness of Mediterranean winters can periodically lead to favourable environmental ...
Integrative approach for precise genotyping and transcriptomics of a salt tolerant introgression line in rice
Rice is the most salt sensitive cereal crop and its cultivation is particularly threatened by salt stress. This study reports the development of salt tolerant introgressed lines (ILs) derived from crosses between the salt ...
Ecología química en el bentos antártico
El estudio de las interacciones entre los organismos mediadas por sustancias químicas, lo que se denomina ecología química, nos da información sobre la biología de las especies implicadas, el funcionamiento de la comunidad ...
Inventaire et cartographie des peuplements de Fucales du Parc National de Port-Cros
En Méditerranée, les algues brunes du genre Cystoseira C. Agardh et Sargassum C. Agardh sont les principaux représentants de l’ordre des Fucales Kylin. La plupart des espèces sont endémiques de Méditerranée et se développent ...
Reaffirming the Loma Mountains National Park in Sierra Leone as a critical site for the conservation of West African chimpanzee (<em>Pan troglodytes verus</em>)
The population of West African chimpanzees (Pan troglodytes verus) is declining rapidly mostly due to the impact of human activities and habitat loss. Sierra Leone harbors the third largest population of this subspecies, ...
Age-related variability in buccal dental microwear in Middle and Upper Pleistocene human populations.
Infants are thought to present a different buccal microwear pattern than adults and these, therefore, are generally analyzed separately. However, El-Zaatari & Hublin [2009] showed that occlusal texture in Neandertal and ...
Enjoying the warming Mediterranean: transcriptomic responses to temperature changes of a thermophilous keystone species in benthic communities
Information about the genomic processes underlying responses to temperature changes is still limited in non‐model marine invertebrates. In this sense, transcriptomic analyses can help to identify genes potentially related ...
Changing feeding habits and ontogenetic dimorphism in juveniles and adults Aplysia punctata (Cuvier, 1803) (Mollusca, Gastropoda, Heterobranchia) in the Mediterranean Sea
Specimens of Aplysia punctata inhabiting the Catalonian coast (NE Spain, Western Mediterranean Sea) display two different color patterns, which have been thought to represent two distinct species. However, molecular analyses ...
