“…However, because ungulates are species with usually very large home ranges and many large carnivores worldwide have also been shown to be severely affected by the presence of roads, the findings are likely to be applicable to many other places worldwide. These functions have been previously applied only once, to assess the impacts on roads in areas of high diversity value in Sweden (49).…”

Habitat loss and deterioration represent the main threats to wildlife species, and are closely linked to the expansion of roads and human settlements. Unfortunately, large-scale effects of these structures remain generally overlooked. Here, we analyzed the European transportation infrastructure network and found that 50% of the continent is within 1.5 km of transportation infrastructure. We present a method for assessing the impacts from infrastructure on wildlife, based on functional response curves describing density reductions in birds and mammals (e.g., road-effect zones), and apply it to Spain as a case study. The imprint of infrastructure extends over most of the country (55.5% in the case of birds and 97.9% for mammals), with moderate declines predicted for birds (22.6% of individuals) and severe declines predicted for mammals (46.6%). Despite certain limitations, we suggest the approach proposed is widely applicable to the evaluation of effects of planned infrastructure developments under multiple scenarios, and propose an internationally coordinated strategy to update and improve it in the future.anthropogenic development | birds | Europe | mammals | road-effect zone

“…Roads may cause harmful effects on aquatic ecosystems, due to alternations in hydrological processes (Karlson & Mörtberg, 2015) and pollutants from vehicles, asphalt, and operation and maintenance activities (Meland et al, 2011;Meland, Salbu, & Rosseland, 2010).…”

Stormwater ponds are used to compensate for the adverse effects that road runoff might have on the natural environment. Depending on their design and placement, stormwater ponds can act as both refugia and traps for local biodiversity. To evaluate the impact of stormwater ponds on biodiversity, it is critical to use effective and precise methods for identification of life associated with the water body. DNA metabarcoding has recently become a promising tool for identification and assessment of freshwater biodiversity. Using both morphology and DNA metabarcoding, we analyze species richness and biological composition of samples from 12 stormwater ponds and investigate the impact of pond size and pollution levels in the sediments and water column on the macroinvertebrate community structure. DNA metabarcoding captured and identified more than twice the number of taxa compared to morphological identification. The (dis)similarity of macroinvertebrate community composition in different ponds showed that the ponds appear better separated in the results obtained by DNA metabarcoding, but that the explained variation is higher for the results obtained by morphologically identification, since it provides abundance data. The reliance on morphological methods has limited our perception of the aquatic biodiversity in response to anthropogenic stressors, thereby providing inaccurate information for appropriate design and management of stormwater ponds; these drawbacks can be overcome by DNA metabarcoding. Synthesis and applications. The results indicate that DNA metabarcoding is a useful tool in identifying species, especially Diptera, which are difficult to determine. Application of DNA metabarcoding greatly increases the number of species identified at each sampling site, thereby providing a more accurate information regarding the way the ponds function and how they are affected by management.

“…LTIs lead to a net disruption of the natural habitats that they cross, splitting them into several distinct patches. Most of the effects of fragmentation on biodiversity detailed above are true for LTIs and have been documented [15]. In particular, LTIs result in an indirect decrease of abundance and species diversity due to habitat fragmentation [16,17].…”

Background:The role of linear transportation infrastructures (roads, railways, oil and gas pipelines, power lines, rivers and canals) in fragmenting natural habitats has been demonstrated. Yet, the potential of habitat or corridor of their verges (road and railway embankments, strips of grass under power lines or above buried pipelines, or waterway banks) for biodiversity remains controversial. In a context of decreasing natural habitats, the potential of anthropogenic areas for contributing to wildlife conservation should be considered. Moreover, how linear transportation infrastructure verges should be managed in order to favor biodiversity is a crucial question. The present work describes the protocol of the first systematic synthesis of evidence of the potential of linear transportation infrastructure verges as habitat and/or corridor for biodiversity. Outcomes of the study will be useful for helping managers to improve their practices or for prioritizing actions of ecological restoration. Methods:The subject population will include both flora and fauna of the temperate climate, either species or communities. Exposures to linear transportation infrastructure verges, interventions of verge management (mowing, pruning, etc.) and environmental disturbances (pollution, wildfires, etc.) will be included. Both temporal and spatial comparators will be considered. Relevant outcomes will include dispersal, species richness and abundance. The scientific literature on the topic of the review may turn out to be very heterogeneous. Various management types, biodiversity outcomes and study designs might be conceived. If any combination of these is covered by a sufficient number of studies, we will perform a meta-analysis. At the least, we will produce a systematic map and a narrative synthesis.
