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 ...
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 ...
Phytoplankton across tropical and subtropical regions of the Atlantic, Indian and Pacific oceans.
We examine the large-scale distribution patterns of the nano- and microphytoplankton col- lected from 145 oceanic stations, at 3 m depth, the 20% light level and the depth of the sub- surface chlorophyll maximum, during ...
Dimorfismo sexual de la clavícula: un estudio basado en una muestra actual española.
Los objetivos de este trabajo fueron estudiar el dimorfismo sexual de la clavícula, teniendo en cuenta su asimetría direccional, y aportar algoritmos útiles para el diagnóstico sexual. El material utilizado fueron 77 ...
Managing abandoned Mediterranean mountain landscapes: The effects of donkey grazing on biomass control and floral diversity in pastures
Traditional Mediterranean Mountain landscapes in Spain have suffered dramatic environmental and social changes over the last seven decades. The loss of these landscapes has had consequences for biodiversity, soil erosion, ...
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, ...
El fons marí de les illes Medes i el Montgrí: quatre dècades de recerca per a la conservació
La recollida sistemàtica de dades per obtenir sèries temporals llargues de determinades variables que ens donin informació de com evoluciona un determinat ecosistema, una comunitat o una espècie, el que es coneix com a ...
Biology and ecology of lionfish (Pterois volitans) in the Corales de Profundidad Natural National Park, Colombian Caribbean.
En el ambiente mesofótico se observaron 237 especímenes de Pterois, mayoritariamente en la zona mesofótica superior. Los machos fueron más grandes que las hembras con modelos de crecimiento diferenciados. Se identificaron ...
Principales patrones de distribución de plantas vasculares de los Países Catalanes
El área de estudio, los Países Catalanes, comprende la parte oriental de la Península Ibérica y las islas adyacentes (Bolòs, 1985). Su superfície es aproximadamente de 70.000 km2 y se trata de un área bastante bien estudiada ...
<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 ...
A Comparative Analysis of DNA Metabarcoding and Morphological Identification in Diatoms Reveals Similar Patterns of Environmental Response
Diatoms are widely used as environmental sentinels and are commonly studied through morphological identification. However, this method requires specialist knowledge, which is becoming increasingly scarce, resulting in ...
Seasonality and predictability shape temporal species diversity
Temporal environmental fluctuations, such as seasonality, exert strong controls on biodiversity. While the effects of seasonality are well known, the predictability of fluctuations across years may influence seasonality ...
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 ...
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 ...
Global phenological insensitivity to shifting ocean temperatures among seabirds
Reproductive timing in many taxa plays a key role in determining breeding productivity1, and is often sensitive to climatic conditions2. Current climate change may alter the timing of breeding at different rates across ...
Biased adult sex ratios in western Europe populations of little bustard Tetrax tetrax as a potential warning signal of unbalanced mortalities
<p>Adult sex ratios (ASRs) have proved to correlate with population trends, which make them</p><p>potential useful indicators of a species’ population trajectory and conservation status. We</p><p>analysed ASRs and proportion ...
Translating high throughput phenotyping into genetic gain
Inability to efficiently implement high-throughput field phenotyping is increas-ingly perceived as a key component that limits genetic gain in breeding pro-grams. Field phenotyping must be integrated into a wider context ...
The complex organization of human cognitive domains and their heritability: a systematic review
Una revisión sistemática de la organización compleja de los dominios cognitivos humanos y su heredabilidad. Antecedentes: se ha propuesto que la estructura de la cognición humana respondería a un sistema jerárquico, donde ...
