Addressing the challenge of photovoltaic growth: Integrating multiple objectives towards sustainable green energy development,
Abstract The Spanish Bonelli's Eagle populations have decreased markedly because of high mortality. We recorded 424 cases dead eagles between 1990 and 1998 in Spain which after cross-comparison corresponded to 377 individuals. Electrocution (55% deaths), followed by direct persecution (26%) were the main causes death. No differences cause death found sexes. Non-adult mostly died electrocution whereas adults mainly victims persecution. A log-linear model showed that these associated with a...
Abstract The analysis of 267 records non-natural mortality the Spanish imperial eagle Aquila adalberti over a 16-year period (1989-2004) shows an annual rate 15.1 individuals found dead per year and that electrocution (47.7%) poisoning (30.7%) were most frequent causes mortality. Most cases (91.7%) human origin, those 92.3% accidental. Just half (50.2%) related to transmission electricity activity (collisions electrocution), 40.7% game practices livestock protection (control predators). No...
ABSTRACT Bird electrocution on power lines is an important conservation problem that affects many endangered species. We surveyed 3,869 pylons in the Barcelona Pre‐littoral Mountains (Catalonia, NE Spain) and collected 141 carcasses of electrocuted birds, mainly raptors corvids. Univariate analysis indicated metal with pin‐type insulators or exposed jumpers, connector wires, located ridges, overhanging other landscape elements, open habitats low vegetation cover were most dangerous. A...
Abstract Agricultural intensification over the last 60 decades has been linked to decreases in biodiversity and breeding populations of several avian species farmlands. However, agricultural not affected all same way transformed landscapes can still provide suitable habitats for tolerant some degree anthropogenic change. Understanding habitat selection man‐made is a pre‐requisite effective management conservation that use them. habitat‐related choices made by individuals occupying these are...
Background There are few studies of careful examination wildlife casualties in Wildlife Rehabilitation Centers. These essential for detecting menaces to wild species and providing objective criteria about cost-benefit treatments those centers. The release rate is considered the main outcome indicator, but other parameters such as length stay at center a index expressed number released animals per euro day, could be used reliable estimators rehabilitation costs. Methodology A retrospective...
Abstract Capturing wild animals for research or conservation purposes may cause some adverse effects, which is only acceptable if these are outweighed by benefits. We used information from 3 on‐going telemetry studies on the endangered little bustard ( Tetrax tetrax ) in Western Europe to evaluate risk factors associated with capture and handling. Of 151 telemetered birds, 23 (15.2%) exhibited impaired mobility coordination after release, probably related occurrence of myopathy. Among 10...
The next reform of the EU Common Agricultural Policy (CAP) for period 2021-2027 (currently extended to 2023-2030) requires approval by European Commission a Strategic Plan with environmental objectives each Member State. Here we use best available scientific evidence on relationships between agricultural practices and biodiversity delineate specific recommendations development Spanish Plan. Scientific shows that Spain should (1) identify clear regional targets landscape-level measures needed...
European green agricultural policies have been relaxed to allow cultivation of fallow land produce animal feed and meet shortfalls in exports from Ukraine Russia. However, conversion semi-natural habitats will disproportionately impact long term biodiversity food security.
The population of the Vulnerable Spanish imperial eagle Aquila adalberti has experienced a gradual recovery from 38 pairs (1974) to 198 (2004). We analysed spatial and temporal variation demographic parameters for 1981–2004. Annual productivity was 1.19–1.32 chicks per female adult survival rate 0.918–0.986. Survival during post-fledging period 0.894 annual dispersing individuals 0.561. Three phases evolution were distinguished: growth (1981–1993), stability or slight decrease (1994–1999)...
Summary The Little Bustard Tetrax tetrax (Linnaeus, 1758) is a medium-sized, ‘Near Threatened’ steppe bird, whose Iberian population has been alarmingly declining over recent decades. Although this loss mainly attributed to agricultural intensification, there no information on adult mortality levels and their drivers. Based joint effort combining all the tracking data Bustards collected period of 12 years by research teams working with species in Iberia, we found that annual anthropogenic...
Flight capacity is one of the most important innovations in animal evolution; it only evolved insects, birds, mammals and extinct pterodactyls. Given that powered flight represents a demanding aerobic activity, an efficient cardiovascular system essential for continuous delivery oxygen to pectoral muscles during flight. It well known limiting step circulation stroke volume (the blood pumped from ventricle body each beat), which determined by size ventricle. Thus, fresh mass heart simple...
Abstract Interspecific competition is a dominant force in animal communities that induces niche shifts ecological and evolutionary time. If occurs, expansion can be expected when the competitor disappears because resources previously inaccessible due to competitive constraints then exploited (i.e., release). Here, we aimed determine potential effects of interspecific between little bustard ( Tetrax tetrax ) great Otis tarda using multidimensional approach with habitat distribution data. We...
Abstract In the face of dramatic worldwide decline farmland bird populations, preservation fallow fields is a conservation measure encouraged through subsidies (e.g. agri‐environmental schemes, AES). Beyond general benefits increasing availability for endangered steppe there lack knowledge on how management can contribute to meeting species‐specific habitat requirements. We used occurrence data from three species protected at EU level (Stone Curlew Burhinus oedicnemus , Little Bustard Tetrax...
Capsule Male Western Capercaillies Tetrao urogallus use their vocalizations during the breeding season for territorial and reproductive purposes, these have genetically predefined characteristics that confer each bird with a unique distinguishable vocal signature.
Abstract 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 processes, which may hinder a comprehensive understanding of how why populations change over time. The advent Integrated Models (IPMs) recent developments in spatial mark–recapture have enabled deeper insights into demography dispersal. In this study, we merged both kinds spatially explicit IPM. By...
Bio-acoustic study on the richness and abundance of bats in Natural Interest Site Les Obagues del Corb In summer 2021, ultrasound recordings were carried out at 16 points (EIN) (Catalonia) order to determine composition chiropteran communities this protected natural space. We recorded a total 11 species or phonic groups, with an average 5.9 per point 20%. The most widespread common pipistrelle Pipistrellus pipistrellus Kulh's kuhlii, both almost ubiquitous locally abundant, followed some...
During 1980-97, trichomoniasis was detected in nestlings of Bonelli's eagle Hieraaetus fasciatus Catalonia (Spain). In 1993 Trichomonas gallinae isolated 36% (n = 39) and affected 41% broods 22). Overall, one the most important single nestling mortality factor, accounting for 22% total chick mortality, causing death 2% chicks. Trichomoniasis deaths took place during second half period. The median age at 45.5 days. Although presence parasite not related to composition diet or parental age,...
