Although scrub cover is generally regarded as an important habitat component of the European wild rabbit Oryctolagus cuniculus, little known about species' responses to variation in structure and composition. Such information required for conservation management rabbits Mediterranean scrublands Iberian Peninsula (southwestern Europe), where species both a key resource range endangered predators popular game species. To address this issue, we estimated effects variables characterising...
Summary Predator conservation management requires detailed understanding of the ecological circumstances associated with predation, especially that on economically valuable prey. We examined mechanisms behind Bonelli's eagle Hieraaetus fasciatus predation prey domestic origin, using dietary data from 22 pairs breeding in south‐west Portugal (1992–2001) together information landscape composition and availability. Numerically, 42·7% (37·7% biomass) comprised species, about 70% which were rural...
Summary Conservation science increasingly focuses on how ecosystem functioning is affected by anthropogenic pressures, which implies an understanding of the structural and functional changes in biological assemblages requires indicators to detect such within a suitable time frame. A novel approach that combines spatial analysis fishing gradients (based vessel monitoring system records) with distance‐based linear models was used assess response several metrics fish trawling, four distinct...
Bias in underwater visual census has always been elusive. In fact, the choice of sampling method and behavioural traits fish are two most important factors affecting bias, but they still treated separately, which leads to arbitrarily chosen methods. FishCensus, a two-dimensional agent-based model with realistic movement, was used simulate problematic SCUBA diving methods understand how methodology affects precision bias counts. Using fixed true density 0.3 fish/m2 visibility 6 m, 10 counts...
Monitoring marine contamination by floating litter can be particularly challenging since debris are continuously moving over a large spatial extent pushed currents, waves, and winds. Floating have mostly relied on opportunistic surveys from vessels, modeling and, more recently, remote sensing with spectral analysis. This study explores how low-cost commercial unmanned aircraft system equipped high-resolution RGB camera used as an alternative to conduct in coastal waters or vessels. The...
Abstract Fish sounds are a significant component of marine soundscapes. Recently, passive acoustic monitoring (PAM) arose as promising tool for ecological monitoring, but good characterization fish communities is still needed. This study the first to characterize community at biogeographic transition zone in Northeast Atlantic. The research was conducted protected area (MPA) along Portuguese mainland coast. Based on literature review, we identified 29 (19.3%) sound-producing species present...
Marinas are a gateway for the introduction and establishment of non-indigenous species (NIS). In these habitats, competition predation crucial determinants NIS invasiveness. However, fish trophic preferences biotic effects inside marinas poorly known. This study proposes novel method that combines deployment settlement plates to recruit different assemblages, followed by their use as bait in remote underwater video systems. combined approach, addressed foraging system (RVFS), can record...
Marine Protected Areas (MPAs) require effective indicators to assess their performance, in compliance with the goals of relevant national and international commitments. Achieving prioritizing shortlists multidisciplinary demands a significant effort from specialists depict multiple conservation socioeconomic interests, large complexity natural systems. The present paper describes structured expert-based methodology (process outputs) co-define list MPA performance indicators. This work was...
Over one-third of all elasmobranch species are at risk extinction worldwide. This study aims to contribute their conservation worldwide through a case that combines georeferenced data on presence and abundance with spatial distribution human activities, Spatial Conflict Risk Index (SCRI). The SCRI pinpoints possible areas obtained from the overlap impacting activities. Data around Marine Protected Area, Berlengas Natural Reserve (Portugal) were four non-invasive methods: Baited Remote...
There is growing evidence that studying aquatic acoustic communities can provide ecologically relevant information. Understanding these may offer unique insights into species behaviour and ecology, while consolidating passive monitoring as a tool for mapping the presence of target or estimating changes in biodiversity. Fish be significant soundscape contributors, but most soniferous fish are yet to identified. Here, we crossed information three key Lusitanian Province Temperate Northern...
In the last decades increasing records of morphological abnormalities in many amphibian populations have become subject scientific interest. Once considered a mere curiosity, this worldwide phenomenon has been highlighted as potential local conservation issue, for it appears to be yet another threat diversity. Our study reports first cases deformities North-Central Portugal, which are put context with review comprising European since 18th century. Amphibian (Lissotriton boscai, Triturus...
