European rabbit restocking: a critical review in accordance with IUCN (1998) guidelines for re–introduction

Repoblaciones de conejo europeo: una revisión crítica según las directrices de la IUCN (1998) para las reintroducciones Las repoblaciones de conejo europeo son una de las medidas más empleadas en los cotos de caza y en los proyectos de conservación en España, Francia y Portugal, donde el conejo es una especie clave. El objetivo de este trabajo consiste en revisar el conocimiento actual sobre los factores que afectan al establecimiento de las poblaciones de conejo reintroducidas según las directrices de la IUCN (1998), a fin de determinar las lagunas de conocimiento en este ámbito y destacar las técnicas que mejoran los buenos resultados reales de las reintroducciones. Ocho de los 17 puntos seleccionados de estas directrices se identificaron como desconocidos o parcialmente estudiados, incluidos importantes aspectos como el manejo y la liberación de conejos salvajes criados en cautividad, la elaboración de planes de transporte y seguimiento, la aplicación de programas de vacunación y los estudios a largo plazo posteriores a la liberación. Por lo tanto, los investigadores deben concentrar sus esfuerzos en suprimir esta falta de conocimiento y los gestores deben analizar todos los factores que aquí revisamos, con el objetivo de establecer unas directrices precisas para las futuras repoblaciones de conejo.Repoblaciones de conejo europeo: una revisión crítica según las directrices de la IUCN (1998) para las reintroducciones Las repoblaciones de conejo europeo son una de las medidas más empleadas en los cotos de caza y en los proyectos de conservación en España, Francia y Portugal, donde el conejo es una especie clave.

The aim of this work was to review current knowledge regarding rabbit restocking in accordance with the IUCN (1998) guidelines for re–introduction in order to identify gaps in knowledge and highlight the techniques that improve the overall success rate. Eight of 17 items selected from these guidelines were identified as partly studied or unknown, including important items such as the management and release of captive–reared wild rabbits, the development of transport and monitoring programs, the application of vaccine programs, and post–release long–term studies. Researchers should therefore concentrate their efforts on bridging these knowledge gaps, and wildlife managers should consider all the factors reviewed herein so as to establish accurate management guidelines for subsequent rabbit restocking programs

Factores que afectan a la abundancia de la perdiz roja Alectoris rufa en cotos de caza mayor: implicaciones para la gestión y conservación

[EN]: The red-legged partridge Alectoris rufa is not only the most important bird game species but also an important prey species for many predators in Iberia. However, its populations have significantly declined in recent decades, principally as the result of agricultural intensification on arable land. Its abundance has also undergone a significant decline in forested areas over the last few decades, where wild ungulate management and abundance have increased. In this scenario, we aimed to test the factors that affect red-legged partridge abundance in relation to high wild ungulate (wild boar and red deer) abundance in south-central Spain. The factors included as predictors were carnivore, wild boar and red deer abundances, vegetation features, nest predation rate and invertebrate availability. Red deer abundance showed a negative relationship with partridge abundance in spring (non-significant negative trends were also evident for carnivore and wild boar), whereas variables related to food availability (grass biomass, Hemipteran abundance and total invertebrate mass) had a positive effect in the same season. Moreover, deer and carnivore abundances and spring nest predation rate were negatively associated with partridge abundance in autumn. Plant biomass and Hemipteran abundance were negatively correlated with wild boar abundance, whereas maximum pasture height was negatively related to red deer and wild boar abundance. Overall, our results show that high ungulate densities may negatively affect partridge abundance, which may be mediated by (i) a reduction in food availability (invertebrate and herbaceous plant biomass) and (ii) nest predation by wild boar. This research has shown that current intensive big-game hunting management schemes in south-central Spain are often incompatible with red-legged partridge conservation, and that these effects should be taken into account when defining big-game management and conservation policies.[ES]: La perdiz roja Alectoris rufa no solo es el ave de caza más importante, sino que también es una importante presa para muchos depredadores en Iberia. Sin embargo, sus poblaciones han disminuido significativamente en las últimas décadas, principalmente como resultado de la intensificación de la agricultura en zonas agrícolas. Sus abundancias también han sufrido un descenso significativo en zonas forestales durante los últimos decenios donde la gestión de ungulados silvestres y sus abundancias se han incrementado. En este escenario, nuestro objetivo ha sido evaluar los factores que afectan a la abundancia de perdiz roja en un contexto de alta abundancia de ungulados silvestres (jabalí y ciervo) en el centro-sur de España. Los factores incluidos como predictores fueron la abundancia de carnívoros, jabalí y ciervo, las características de la vegetación, la proporción de nidos depredados y la disponibilidad de invertebrados. La abundancia de ciervo mostró una relación negativa con la abundancia de perdiz en primavera (también se evidenciaron tendencias negativas no significativas para carnívoros y jabalí), mientras que las variables relativas a la disponibilidad de alimento (biomasa herbácea, abundancia de hemípteros y el peso total de los invertebrados) tuvieron un efecto positivo en la misma estación. Por otra parte, en otoño, la abundancia de ciervos y carnívoros, y la tasa de depredación de nidos en primavera se asociaron negativamente con la abundancia de perdiz. La biomasa de herbáceas y la abundancia de hemípteros se correlacionaron negativamente con la abundancia de jabalíes, mientras que la altura máxima del pasto estuvo negativamente asociada con la abundancia de ciervo y jabalí. En general, nuestros resultados muestran que las altas densidades de ungulados podrían afectar negativamente a la abundancia de perdiz mediado por (i) una reducción en la disponibilidad de alimento (invertebrados y biomasa de herbáceas) y (ii) la depredación de nidos por el jabalí. Esta investigación ha puesto de manifiesto que los actuales sistemas intensivos de gestión de la caza mayor en el centro-sur de España no son compatibles con la conservación de la perdiz roja, y que por lo tanto, estos efectos deben ser considerados a la hora de definir las políticas para la gestión de la caza mayor y la conservación.To the Environmental Council of the Andalusian Autonomous Government for financing this work via a project to improve the habitat of the black vulture Aegypius monachus in Córdoba province.Peer Reviewe

The high abundance of wild ungulates in a mediterranean region: is this compatible with the European rabbit?

This is an Open Access article.The landscape in southern Iberia has, over the last four decades, altered as a result of the land abandonment, while the abundance of wild boar Sus scrofa and red deer Cervus elaphus has simultaneously increased, and some key prey species such as the European rabbit Oryctolagus cuniculus have declined. In this work we explore: 1) the relationships between big game species (red deer and wild boar) and rabbit abundance, and 2) whether these relationships could have effects on food quality (total nitrogen available in the pasture and percentage of leguminosae) and food availability of (herbaceous cover). We therefore selected nine big game estates with a range of abundance as regards ungulates and similar Mediterranean habitat. Wild boar abundance was statistically negative in relation to rabbit abundance, while no significant statistical relationships between rabbit abundance and habitat structure and forage quality were evidenced. However, wild boar abundance, but not that of red deer, was negatively associated with leguminosae cover, and the percentage of surface rooted by wild boar was negatively associated with the percentage of herbaceous cover. Overall, our results suggest that the abundance of wild boar is negatively related to that of rabbits, and could have a negative effects on rabbit abundances by food competition as a result of: 1) a decrease in herbaceous coverage and leguminosae in the pasture and 2) an increase in the total percentage of soil disturbed as a result of rooting.We should like to thank to the Andalucía Autonomous Government’s Environmental Council for financing this work via a project to improve the habitat of the black vulture in Córdoba province.Peer Reviewe

Effect of wild ungulate density on invertebrates in a Mediterranean ecosystem

Efecto de la densidad de ungulados silvestres sobre los invertebrados en un ecosistema Mediterráneo En las últimas décadas, la abundancia y distribución de determinadas especies de caza mayor, especialmente el ciervo rojo (Cervus elaphus) y el jabalí (Sus scrofa), han aumentado en la zona centromeridional de España como resultado de las estrategias de gestión cinegética. La alta densidad de estas especies de ungulados puede afectar a la abundancia de los invertebrados epigeos. Estudiamos la relación entre la abundancia de las especies de caza mayor y la biodiversidad, la riqueza de taxones, la biomasa de invertebrados y su frecuencia en nueve fincas de caza, y se comparó con las zonas de exclusión de ungulados. De por sí, la exclusión de ungulados afectó a la riqueza de invertebrados, ya que se encontraron valores más bajos en las parcelas abiertas, mientras que las mayores diferencias en la diversidad de invertebrados entre parcelas abiertas y cercadas se encontraron en zonas con una alta densidad de jabalíes. Donde la densidad de jabalíes era alta, el número de invertebrados disminuyó, mientras que donde era baja, el ciervo rojo tuvo un efecto positivo en la abundancia de invertebrados. Así, las parcelas cercadas parecían ofrecer refugio a los invertebrados, sobre todo donde los jabalíes eran abundantes. Este estudio apoya la idea de que las poblaciones con una alta densidad de ungulados perjudican a la estructura de las comunidades faunísticas, probablemente debido a la disminución de la disponibilidad de alimentos como consecuencia del sobrepastoreo, la modificación de las condiciones de los micronichos ecológicos y la depredación directa. Sin embargo, los efectos dependieron del grupo de invertebrados, ya que las especies saprofitas podrían beneficiarse de la alta abundancia de ungulados. Nuestros resultados reflejan la necesidad de controlar la densidad de las poblaciones de ungulados en condiciones mediterráneas en el suroeste de Europa y de establecer parcelas de exclusión de ungulados.In recent decades, the abundance and distribution of certain big game species, particularly red deer (Cervus elaphus) and wild boar (Sus scrofa), have increased in south central Spain as a result of hunting management strategies. The high density of these ungulate species may affect the abundance of epigeous invertebrates. We tested the relationships between big game abundance and biodiversity, taxon richness, the biomass of invertebrates and their frequency on nine hunting estates and in comparison to ungulate exclusion areas. Ungulate exclusion itself affected invertebrate richness, since lower values were found in the open plots, whereas the highest differences in invertebrate diversity between fenced and open plots was found in areas with high wild boar density. Where wild boar densities were high, the number of invertebrates decreased, while where they were low, red deer had a positive effect on invertebrate abundance. Fenced plots thus seemed to provide refuge for invertebrates, particularly where wild boar were abundant. This study supports the idea that the structure of fauna communities is damaged by high density populations of ungulates, probably due to decreased food availability owing to overgrazing, modified conditions of ecological microniches and direct predation. However, the effects depended on the group of invertebrates, since saprophytic species could benefit from high ungulate abundance. Our findings reflect the need to control ungulate population density under Mediterranean conditions in south–western Europe and to implement ungulate exclusion plots.Efecto de la densidad de ungulados silvestres sobre los invertebrados en un ecosistema Mediterráneo En las últimas décadas, la abundancia y distribución de determinadas especies de caza mayor, especialmente el ciervo rojo (Cervus elaphus) y el jabalí (Sus scrofa), han aumentado en la zona centromeridional de España como resultado de las estrategias de gestión cinegética.

Redox-dependent and redox-independent functions of Caenorhabditis elegans thioredoxin 1

Thioredoxins (TRX) are traditionally considered as enzymes catalyzing redox reactions. However, redox-independent functions of thioredoxins have been described in different organisms, although the underlying molecular mechanisms are yet unknown. We report here the characterization of the first generated endogenous redox-inactive thioredoxin in an animal model, the TRX-1 in the nematode Caenorhabditis elegans. We find that TRX-1 dually regulates the formation of an endurance larval stage (dauer) by interacting with the insulin pathway in a redox-independent manner and the cGMP pathway in a redox-dependent manner. Moreover, the requirement of TRX-1 for the extended longevity of worms with compromised insulin signalling or under calorie restriction relies on TRX-1 redox activity. In contrast, the nuclear translocation of the SKN-1 transcription factor and increased LIPS-6 protein levels in the intestine upon trx-1 deficiency are strictly redox-independent. Finally, we identify a novel function of C. elegans TRX-1 in male food-leaving behaviour that is redox-dependent. Taken together, our results position C. elegans as an ideal model to gain mechanistic insight into the redox-independent functions of metazoan thioredoxins, overcoming the limitations imposed by the embryonic lethal phenotypes of thioredoxin mutants in higher organisms.NIH Office of Research Infrastructure P40 OD010440Spanish Ministry of Economy and Competitiveness BFU2015- 64408-PFondo Social Europeo BFU2015- 64408-PNational Institute of Allergy and Infectious Diseases of the National Institutes of Health R01AI07640

High rabbit abundance proves detrimental to the population growth rate in European rabbit (Oryctolagus cuniculus L.) extensive breeding enclosures

[EN] The European rabbit (Oryctolagus cuniculus L.) is a key prey species in Mediterranean ecosystems that has declined in its natural ranges as a result of diseases and loss of habitat. This situation has led to the production of wild rabbits in enclosures in which they can acclimate and breed. The efficiency of these enclosures as extensive breeding systems is defined by their population growth rate (PGR). The aim of this study is to analyse the effect of rabbit abundance on the PGR. This has been done by creating general linear models to explain autumn and spring PGR with the use of rabbit abundance estimates, enclosure size, aerial predation and previous PGR as possible explanatory variables. Rabbit abundance and enclosure size negatively affected the autumn PGR, while only rabbit abundance affected the spring PGR in the best-fit models. It is suggested that maintaining rabbit densities at fewer than 30 rabbits per hectare might help to optimise the efficiency inside enclosures.L.R.A. was supported by a grant from the University of Córdoba.

Factors affecting wild rabbit production in extensive breeding enclosures: how can we optimise efforts?

[EN] The declining rabbit population in the Iberian Peninsula has led hunters and authorities to rear rabbits in captivity systems for their subsequent release. One alternative method to intensive rabbitry systems is the use of extensive breeding enclosures, since they produce animals of greater quality for hunting and conservation purposes. However, some of the factors that affect rabbit production in breeding enclosures are still unknown. The present study used partial least squares regression (PLSR) to analyse the effects of plot size, scrub cover, slope, initial rabbit abundance, the resources needed to dig warrens, predation and proximity to other enclosures on rabbit abundance. The results of our study show a positive effect of the number of other fenced plots within a radius of 3 km, a positive relationship with the availability of optimal resources for building warrens and a positive influence of intermediate values of scrub cover. According to our results, to maximise rabbit production in the enclosures it would be advisable to concentrate the restocking effort by ensuring that the restocking plots are close to each other, thus avoiding isolated enclosures. Furthermore, the selection of plots with an appropriate scrub cover and high availability of elements that favour the construction of warrens, such as large stones, sloping land or tall shrubs, may optimise results.We would like to thank S.

His452Tyr polymorphism in the human 5-HT2A receptor affects clozapine-induced signaling networks revealed by quantitative phosphoproteomics

Antipsychotic drugs remain the current standard for schizophrenia treatment. Although they directly recognize the orthosteric binding site of numerous monoaminergic G protein-coupled receptors (GPCRs), these drugs, and particularly second-generation antipsychotics such as clozapine, all have in common a very high affinity for the serotonin 5-HT receptor (5-HTR). Using classical pharmacology and targeted signaling pathway assays, previous findings suggest that clozapine and other atypical antipsychotics behave principally as 5-HTR neutral antagonists and/or inverse agonists. However, more recent findings showed that antipsychotics may also behave as pathway-specific agonists. Reversible phosphorylation is a common element in multiple signaling networks. Combining a quantitative phosphoproteomic method with signaling network analysis, we tested the effect of clozapine treatment on the overall level of protein phosphorylation and signal transduction cascades in vitro in mammalian cell lines induced to express either the human 5-HTR or the H452Y variant of the gene encoding the 5-HTR receptor. This naturally occurring variation within the 5-HTR gene was selected because it has been repeatedly associated with schizophrenia patients who do not respond to clozapine treatment. Our data show that short time exposure (5 or 10 min) to clozapine (10 M) led to phosphorylation of numerous signaling components of pathways involved in processes such as endocytosis, ErbB signaling, insulin signaling or estrogen signaling. Cells induced to express the H452Y variant showed a different basal phosphoproteome, with increases in the phosphorylation of mTOR signaling components as a translationally relevant example. However, the effect of clozapine on the functional landscape of the phosphoproteome was significantly reduced in cells expressing the 5-HTR-H452Y construct. Together, these findings suggest that clozapine behaves as an agonist inducing phosphorylation of numerous pathways downstream of the 5-HTR, and that the single nucleotide polymorphism encoding 5-HTR-H452Y affects these clozapine-induced phosphorylation-dependent signaling networks

Determination of the Optimal Size of Photovoltaic Systems by Using Multi-Criteria Decision-Making Methods

The diverse socio-economic and environmental impacts related to the setup of a new photovoltaic installation must be weighed carefully in order to reach the best possible solution. Among the different photovoltaic systems, there are several classification criteria, depending on the technology, application, and size of the modules that define them. The size (installed nominal capacity) stands out as an impartial and critical measure in the decision-making process. In this article, we use a multi-criteria decision-making method to analyze the responses of five experts to a detailed questionnaire in which several different criteria are correlated with various photovoltaic installation sizes. The limitation associated with a low number of experts is addressed with a robustness and sensitivity analysis. With this study, we seek first to apply and demonstrate the feasibility of a methodology that combines technical information with multi-criteria decision-making methods. Second, we obtain a clear result that increases the benefits of a forthcoming photovoltaic installation of modules in distributed generation, adding up to one GW total peak power in standard conditions. We observe a consistent result in which smaller photovoltaic modules provide the ideal solution, as this format maximizes the socio-economic benefits of any installation. If a decision has to be taken about the type of photovoltaic plant to be installed, the conclusion is clear: given a certain size, small, easily scalable installations are the best solution for stakeholders, the inhabitants, and the environment.This research was done thanks to the financial support from MINECO (SPAIN), including FEDER funds: FIS2015-69512-R and ENE2016-79282-C5-5-R, and from Fundación Séneca (Murcia, Spain) Project No. 19882/GERM/15 and projects TIN2014-55024-P from MINECO (SPAIN) P11-TIC-8001 and TIN2017-86647-P from Junta de Andalucía (including FEDER funds) and project FIS2015-69512-R from MINECO (SPAIN) and a doctoral scholarship from MESCYT (Dominican Republic) with the contract No. BIM-434-2017, respectively
