Abstract Area-based conservation is essential to safeguard nature’s diversity. In view of expanding human land use, increasing climate change and unmet targets, area-based requires efficiency effectiveness more than ever. this review, I identify relate pressing challenges promising opportunities for effective efficient protected area governance management, enhance research, decision-making capacity building in under uncertain future developments. reveal that management particularly...
Protected areas (PA) are refugia of biodiversity. However, anthropogenic climate change induces a redistribution life on Earth that affects the effectiveness PAs. When species forced to migrate from protected unprotected track suitable climate, they often face degraded habitats in human-dominated landscapes and higher extinction threat. Here, we assess how conditions expected shift within world's terrestrial PAs (n = 137,432). temperate northern high-latitude biomes predicted obtain...
Abstract Protected areas (PAs) constitute major tools in nature conservation. In the European Union (EU), Birds and Habitats Directives are most important policies for conservation strategy, legally preserving Europe’s characteristic, rare, endemic threatened biota. We used occurrence data species listed directives’ Annexes to assess uniqueness of PAs EU (National Parks, Biosphere Reserves); this is EU’s focal species. developed a novel, multifunctional approach calculate different metrics...
Abstract Protecting global biodiversity is one of the most urgent tasks for coming decades. Area-based conservation a pillar preserving ecosystems and species. Strictly protected areas specifically preserve ecosystem processes. The “EU Biodiversity Strategy 2030” targets strict protection 10% land area. Here we performed first analysis strictly (as IUCN type Ia, Ib, II) across Europe, by investigating their area coverage at level biogeographical regions, countries elevation gradients. We...
The recent rise in temperature and shifting precipitation regimes threaten ecosystems around the globe to different degrees. Treelines are expected respond climate warming by higher elevations, but it is unclear whether they can track changes. Here, we integrated high-resolution aerial imagery with local climatic topographic characteristics study treeline dynamic from 1945 2015 on semi-arid Mediterranean island of Crete, Greece. During period, mean annual at increased 0.81 °C, while average...
Abstract Aim Protected areas are essential to conserve biodiversity and ecosystem benefits society under increasing human pressures of the Anthropocene. Anthropogenic climate change, however, threatens enduring effectiveness protected in conserving providing services, because it modifies redistributes with unknown consequences for functioning within areas. Here, we assess (a) change exposure global terrestrial area estate (b) vulnerability national estates. Location Terrestrial worldwide....
Protected areas (PAs) are aimed to hold the environmental conditions that facilitate species and ecosystems persist. PAs can become climatically unsuitable unable sustain their current number of under climate change. The Natura 2000 (N2K) is largest coordinated conservation tool assigned maintain long-term survival Europe's most significant habitats. In attempting understand effectiveness in face change scenarios, we tested two hypotheses: (1) Alpine Boreal biogeographical regions will...
Current rates of biodiversity loss do not allow for inefficient monitoring. Optimized monitoring maximizes the ratio between information and sampling effort (i.e., time costs). Sampling increases with number size units. We hypothesize that an optimal units can be determined providing maximal via minimal effort. apply approach identifies quadrats. The adapted to any study system. Here we focus on alpine grassland, a diverse but threatened ecosystem. Gran Paradiso National Park, Italy. sampled...
Habitat richness, that is, the diversity of ecosystem types, is a complex, spatially explicit aspect biodiversity, which affected by bioclimatic, geographic, and anthropogenic variables. The distribution habitat types key component for understanding broad-scale biodiversity developing conservation strategies. We used data on European Union (EU) habitats to answer following questions: (i) how do variables affect richness? (ii) Which those factors most important? (iii) How interactions among...
Biogeographical units are widely adopted in ecological research and nature conservation management, even though biogeographical regionalisation is still under scientific debate. The European Environment Agency provided an official map of the Regions (EBRs), which contains boundaries used Habitats Birds Directives. However, these bisect cells EU 10 km × grid for many purposes, including reporting species habitat data, meaning that 6881 overlap two or more regions. Therefore, superimposing...
Abstract The Natura 2000 (N2K) protected area (PA) network is a crucial tool to limit biodiversity loss in Europe. Despite covering 18% of the European Union's (EU) land area, its effectiveness at conserving across taxa and biogeographic regions remains uncertain. Testing this is, however, difficult because it requires considering nonrandom location PAs, many possible confounding factors. We used propensity score matching accounted for effects regions, terrain ruggedness, cover assess N2K...
Abstract Question Do remote sensing signals represent β‐diversity? Does β‐diversity agree with community types? Location UNESCO Man and the Biosphere Reserve, La Palma, Canary Islands. Methods We recorded perennial, vascular plant species abundances in 69 plots (10 m × 10 m) three pre‐defined types along an elevational gradient of 2,400 m: succulent scrubland, Pinus canariensis forest subalpine scrubland. The data consists structural variables from airborne Light Detection Ranging (Li DAR )...
Epiphytes are one of the most diversified plant life forms, whose species richness peaks in tropics and subtropics. Here we examined vertical distribution metrics (i.e., number epiphyte individuals richness) vascular epiphytes orchids ferns) on two dominant host trees Schima wallichii (DC.) Korth. Quercus lanata Sm.) sub-tropical forests Nepal. We sampled a total 72 Q. S. from forest sites: government protected national park community managed forest. applied generalized linear mixed models...
Habitat loss from unrelenting human pressure is causing an unprecedented decline in global biodiversity. Protected areas (PAs) are meant to counteract and fragmentation of ecosystems today PAs form the backbone conservation strategies worldwide. However, anthropogenic climate change can severely reduce effectiveness PAs. Conservation professionals need concrete spatial information on climatic changes within order put forward practicable safeguard PA face change. In this study, we take...
Anthropogenic climate change is challenging biodiversity conservation worldwide. Climate metrics derived from future predictions help to assess potential impacts of on biodiversity. Here we calculated velocities across biogeographical regions terrestrial Europe and the Natura 2000 protected area network, largest network Earth. We applied projections for year 2070, considering two emission scenarios, six global models a fine spatial resolution. Areas with very high velocity were identified as...
Climate change impacts the structure, functioning, and distribution of species ecosystems. It will shift ecosystem boundaries, potentially affecting vulnerable ecosystems, such as tropical Africa's high mountain i.e., afroalpine their highly susceptible uniquely adapted species. However, ecosystems along these mountains are not expected to respond similarly change. The ericaceous woody vegetation, located between low-elevation broadleaf forests high-elevation anticipated be affected...
