Despite the protected area expansion over last decades, biodiversity continues to decline. The EU Biodiversity Strategy for 2030, as well Kunming-Montreal Global Framework, call 30 % coverage by areas of land and sea in order halt reverse loss. Here, we use European species assessed threatened on IUCN Red List – ones facing most imminent threat extinction - guide proposed expansion. We overlapped ranges 2290 terrestrial freshwater resident 127,046 (28,130 Natura2000 sites 98,916 nationally...
Abstract Global environmental goals mandate the expansion of protected area network to halt biodiversity loss. The European Union’s Natura 2000 covers 27.3% terrestrial Greece, one highest percentages in Europe. However, extent which this protects Europe’s biodiversity, especially a biodiverse country like is unknown. Here, we overlap country’s with ranges 424 species assessed as threatened on IUCN Red List and present Greece. overlaps average 47.6% mapped range species; far exceeds that...
Education is an important component to achieve biodiversity conservation. Given the need increase environmental awareness and literacy towards more effective conservation participatory management of protected areas, this paper aims investigate level knowledge perceptions Biology students in Greece on Natura 2000 areas. The research was conducted using a standardized questionnaire, administered 434 from five biology departments. students’ score notably low department their study did not...
One of the biggest barriers to conducting ocean science around globe is limited access computational tools and resources, including software, computing infrastructure, data. Open tools, such as open-source open data, online offer promising solutions toward more equitable scientific resources. Here, we discuss enabling power these in under-resourced non-English speaking regions, based on experience gained organization three independent programs West African, Latin American, Indian Ocean...
Abstract Delineating biogeographical regions is one of the primary steps when analysing patterns. In their proposed quantitative framework, Kreft & Jetz (2010, Journal Biogeography , 37 2029–2053) recommended use β sim index to delineate because this turnover measure weakly affected by differences in species richness between localities. A recent study Carvalho et al . (2012, Global Ecology and 21 760–771) critiziced ecological studies, ‐3 index. Here we used simple numerical examples an...
Abstract Stream geodiversity is a novel concept that used to describe the variety of geological, geomorphological and hydrological features at reach‐scale level. In this study, we investigated relationship between ecological indicators based on fishes, benthic macroinvertebrates diatoms for classification rivers in line with Water Framework Directive (WFD) 2000/60/EC. We examined whether can be as proxy indicator quality, further tested if explain significant amount taxa richness variation....
Disentangling the main drivers of species richness and community composition is a central theme in ecology. Freshwater biodiversity patterns have been poorly explored; yet, it has shown that different freshwater biota different, often contrasting responses to environmental gradients. In this study, we investigated relative contribution geographical (habitat-, climate- water quality-related) factors/gradients shaping α- β-diversity macrophytes fish sixteen natural lakes an unexplored Balkan...
The ocean is dynamically changing due to the influence of climate processes and human activities. construction Suez Canal in late nineteenth century opened Pandora's box by facilitating dispersal Red Sea species Mediterranean Sea. In this study, we developed an open-source spatio-temporal numerical analysis framework decodify complex spread non-indigenous fish (NIS) that entered through Canal. We utilized 772 historical detection records 130 NIS disentangle their dynamic space time. results...
The rapid decline of the Greek native Valencia letourneuxi, and its recently described sister species robertae, has been often attributed to habitat degradation, as well aggression from or resource competition with alien mosquitofish Gambusia holbrooki. is extremely wide-spread in Mediterranean freshwater ecosystems, however, documentation on presumed negative impacts fishes limited. In this study, we compared abundance, condition gonad weight spp. no co-occurrence versus mosquitofish, using...
The analysis of plant trait composition has raised significant interest among freshwater ecologists as a complementary approach for assessing the effects environmental change on ecosystem functions. In this study, we investigated patterns functional traits aquatic macrophyte assemblages 74 lotic ecosystems Greece, and identified associations between species variables (hydromorphological physicochemical parameters) through testing hypothesis that features determine spatial structure traits....
In the oligotrophic, phosphorus (P)-limited Eastern Mediterranean Sea (EMS), grazing on heterotrophic bacteria (HB) by pigmented nanoflagellates (PNF) through mixotrophy is a significant source of bacterial mortality and P-dependent. Heterotrophic (HNF) are also important consumers HB. However, there still no conceptual framework describing flows carbon (C) P EMS microbial food web that takes into account mixotrophic behavior PNF. present modelling study, we explore qualitatively pathways C-...
The Mediterranean Sea (MED) is prone to species’ introductions, induced by human activities and/or climate change. Recent studies focus on the biological traits that result in such yet a single-area-type approach. Here, we used, analyzed, and compared derived from FishBase for MED, non-indigenous (NIS) neonative (NEO) Mediterranean, adjacent Atlantic (ATL) Red (RS) species. A quantitative trait-based analysis was performed using random forest determine importance of successful establishment...
Regardless of the efforts European Union, freshwaters are in a state environmental crisis. The Water Framework Directive has established basis for protection and restoration inland coastal waters. In parallel, Birds Habitats Directives protect, maintain or restore, at favourable conservation status, selected species habitats under representative network protected areas. Hence, interplay between EU regulations is high scientific interest practical relevance. this article, Greece used as case...
Ecological information regarding trophic patterns and the inherent structure of freshwater aquatic communities is considered fundamental in ecological research. In this study, Greek fish fauna, belonging to Balkan biodiversity hotspot, were investigated, comparisons species feeding habits among ecoregions performed. The analyses based on widely used level index available composition datasets, along with utilization clustering methods, indicated seven major distinct guilds ecoregions. studied...
The challenges facing the ocean and its resources have become increasingly complex transboundary, requiring coordinated efforts for effective management sustainable use. However, this coordination is currently hindered by uneven distribution of capacity equipment, particularly in developing regions. This article discusses project-based learning (PBL) as a pathway to transferring sharing global sciences. It highlights successful PBL program, well encountered lessons learned. Addressing these...
The Coastal Ocean Environment Summer School In Nigeria and Ghana (COESSING; https://coessing.org) has been run for one week every year since 2015. school, an endorsed project of the United Nations Decade Science Sustainable Development (2021–2030), provided a platform approximately 1,000 scientists from Africa, States, Europe to exchange scientific knowledge, network, learn, collaborate.

In addition to quantifying the taxonomic diversity of aquatic communities, understanding patterns alpha functional (α-diversity) and exploring changes in dissimilarity (β-diversity) can improve our on how ecosystems respond environmental changes. this study, we quantified (α) beta (β) macrophytic assemblages from river sites Greece then, examined relationships with water quality parameters hydromorphological factors. We assigned 6 traits (Ellenberg nutrients indicator, Ellenberg light growth...
