Contribución al conocimiento de los murciélagos (Mammalia, Chiroptera) del Parque Natural de Penyagolosa (provincia de Castellón)
2019
Se exponen los principales resultados obtenidos en los muestreos efectuados en agosto de 2004 en el Parque Natural de Penyagolosa. La comunidad de quirópteros del Parque Natural está integrada por al menos 14 especies. Diez de ellas fueron localizadas en los muestreos, siendo ocho nuevas citas tras ellos. La revisión de la bibliografía e informes técnicos más recientes permiten añadir las restantes cuatro especies. De entre las especies localizadas en los muestreos, destacan las forestales Plecotus auritus (Linnaeus, 1758) y Barbastella barbastellus (Schreber, 1774); las fisurícolas Pipistrellus pipistrellus (Schreber, 1774) y Eptesicus serotinus (Schreber, 1774) y la cavernícola Myotis esc…

Underwater noise from boats: Measurement of its influence on the behaviour and biochemistry of the common prawn (Palaemon serratus, Pennant 1777)
2016
Abstract This study examined the effects of recorded boat noises on the behaviour and biochemistry of the common prawn ( Palaemon serratus ) in laboratory settings. The experiment was carried out in a tank equipped with a video-recording system using six groups (three control and three tested) of eight common prawns (48 animals in total). After habituation for 1 h, the behaviour of the prawns was monitored for 1 h. During the last 30 min, the animals in the test groups were exposed to noise resembling a marine area with high anthropogenic acoustic pollution. The exposure to noise produced significant changes in locomotor patterns, presence inside or outside a shelter, total protein concentr…
A new flatworm species of Temnocephala (Rhabdocoela, Temnocephalidae) ectosymbiont on the freshwater crab Valdivia serrata (Decapoda, Trichodactylida…
2020
A new species of temnocephalan is described from the branchial chambers ofValdivia serratain Colombia asTemnocephala ivandarioisp. nov.The most distinctive characters of the new species are in the cirrus and the epidermal ‘excretory’ syncytial plates. In the present study, the terminology to describe the cirrus of species ofTemnocephalais updated. Comparison between the shape of the cirrus of the temnocephalans associated with trichodactylid crabs is also provided.
Atlas of Finnish bats
2019
This atlas is based on information in museum collections, literature, databases and unpublished data. In the last 150 years, the number of bat species in Finland increased from six to thirteen. Of these, five are common and regularly breeding (Eptesicus nilssonii, Myotis brandtii, Myotis daubentonii, Myotis mystacinus, Plecotus auritus), and eight rare (Eptesicus serotinus, Myotis dasycneme, Myotis nattereri, Nyctalus noctula, Pipistrellus nathusii, Pipistrellus pipistrellus, Pipistrellus pygmaeus, Vespertilio murinus), of which breeding of two (M. nattereri, P. nathusii) have been confirmed. The total number of records in the study is 11 234, of which 9717 are identified to species. The re…
ILTER – The International Long-Term Ecological Research Network as a Platform for Global Coastal and Ocean Observation
2019
International audience; Understanding the threats to global biodiversity and ecosystem services posed by human impacts on coastal and marine environments requires the establishment and maintenance of ecological observatories that integrate the biological, physical, geological, and biogeochemical aspects of ecosystems. This is crucial to provide scientists and stakeholders with the support and knowledge necessary to quantify environmental change and its impact on the sustainable use of the seas and coasts. In this paper, we explore the potential for the coastal and marine components of the International Long-Term Ecological Research Network (ILTER) to fill this need for integrated global obs…
Bees increase oilseed rape yield under real field conditions
2018
prod 2018-210 EA GESTAD INRA; International audience; Oilseed rape (OSR, Brassica napus L.) is a common crop found in many European agricultural landscapes. It ispollinated by a wide variety of insects, but the reported contribution of pollinators to yield varies widely betweenstudies (from 0 to 50%). Moreover, such a contribution has seldom been estimated at the field scale in realfarming conditions. We analysed OSR yields in response to insect pollination; over four years, at two differentscales: farm fields and individual plants. We used both empirical and experimental approaches along a gradientof pollinator diversity and abundance. The empirical approach was based on farm surveys (151 …
Trophic transfer of pesticides: The fine line between predator–prey regulation and pesticide–pest regulation
2020
International audience; Understanding pesticide impacts on populations of target/non-target species and communities is a challenge to applied ecology. When predators that otherwise regulate pest densities ingest prey contaminated with pesticides, this can suppress predator populations by secondary poisoning. It is, however, unknown how species relationships and protocols of treatments (e.g. anticoagulant rodenticide [AR]) interact to affect pest regulation.To tackle this issue, we modelled a heuristic non-spatialized system including montane water voles, specialist vole predators (stoats, weasels) and a generalist predator (red fox) which consumes voles, mustelids and other prey. By carryin…
Can green infrastructure help to conserve biodiversity?
2017
The gradually decreasing connectivity of habitats threatens biodiversity and ecological processes valuable to humans. Green infrastructure is promoted by the European Commission as a key instrument for the conservation of ecosystems in the EU biodiversity strategy to 2020. Green infrastructure has been defined as a network of natural and semi-natural areas, designed and managed to deliver a wide range of ecosystem services. We surveyed Finnish experts' perceptions on the development of green infrastructure within the existing policy framework. Our results show that improving the implementation of existing conservation policy instruments needs to be an integral part of developing green infr…
Positive impacts of important bird and biodiversity areas on wintering waterbirds under changing temperatures throughout Europe and North Africa
2020
Clausen, Preben/0000-0001-8986-294X WOS: 000536149100018 Migratory waterbirds require an effectively conserved cohesive network of wetland areas throughout their range and life-cycle. Under rapid climate change, protected area (PA) networks need to be able to accommodate climate-driven range shifts in wildlife if they are to continue to be effective in the future. Thus, we investigated geographical variation in the relationship between local temperature anomaly and the abundance of 61 waterbird species during the wintering season across Europe and North Africa during 1990-2015. We also compared the spatio-temporal effects on abundance of sites designated as PAs, Important Bird and Biodivers…
