This study deals with the future of traditional agroforestry systems (TAFSs) in northern Mediterranean Basin. Important productive systems, such as ancient non-irrigated olive groves and extensive silvopastoral from subalpine grasslands to coastal landscapes, are being irreversibly degraded, threatening bio-cultural heritage region, an area recognized a global biodiversity hotspot. In midst climate crisis, immediate actions proposed for protection conservation management TAFSs, within new EU...

Greece is a European hotspot for Orthoptera (378 species), yet it has been scarcely explored. We investigated the distribution and habitat preferences of species two endemic genera, Parnassiana Oropodisma, in montane ecosystems central Greece. conducted field surveys from 2021 to 2024 174 sites across seven mountains. The both genera preferred habitats above 1500 m, with species-specific microhabitat parameters: favored moderate slopes dense shrub cover, while Oropodisma substrates...

Many hirundine species construct their nests by carrying mud particles from adjacent areas. This study aimed to investigate for the first time materials that mud-nesting hirundines choose nest construction a mineralogical and sedimentological perspective. For this purpose, we sampled of three sympatric species, namely Barn Swallow (Hirundo rustica), Red-rumped (Cecropis daurica) House Martin (Delichon urbicum), southeastern Europe. Our results showed all tend use clay minerals as cement...

Abstract Orthoptera species are vulnerable to extinction on a global scale. Greece hosts 35% (380 species) of the European fauna with high degree endemic (37%) and threatened (37%). We sampled 46 plots (100 m 2 ) investigate distribution ecological requirement two Greek mountain red‐listed species: Parnassiana parnassica (Ramme, 1926; Orthoptera: Tettigoniidae; Critically Endangered [CR]) Oropodisma (Scudder, 1897; Caelifera; [EN]). Species had restricted geographical range, isolated...

Greece is a European hotspot for Orthoptera (378 species), yet it has been scarcely explored. We investigated the diversity patterns of and ecological mechanisms shaping them by sampling 15 sites (30 plots 1ha) across five habitats in Mount Mitsikeli, Natura 2000 site. The mountain deemed rich (0.4 species/km2), hosting 34 species, including species interest (Paracaloptenus caloptenoides). grassy openings beech–fir forest rural mosaics were found to be important Orthoptera, while grasslands...

Abstract Aim Anthropogenic‐driven biodiversity loss can impact ecosystem stability. However, most studies have only evaluated the diversity–stability relationship at local scale and we do not fully understand which factors stabilize animal populations communities across scales. Here, investigate role of species dispersal ability, climate, spatial distance different facets on stability butterfly multiple Location Primarily Western Europe. Time Period 2005–2016. Major Taxa Studied Butterflies...

Abstract The little owl ( Athene noctua ) is a common raptor in Mediterranean habitats. To acquire more information on its diet, this study identified cranial and post-cranial skeletal material from 70 pellets collected during the 2016 2017 breeding seasons. was used to quantify owl’s relative prey abundance using MNI (minimum number of individuals), taphonomical unit. This first examine diet Peloponnese (southern Greece). After examining 3,691 isolated exoskeletal remains processed pellets,...

This paper reports on the educational program “Something’s flying around us” that took place in Zoological Museum of University Patras, based constructivism, under citizen science project “Ornithopolis”. The aim was to support primary school pupils identification bird species and enhance their awareness about urban diversity using exhibits dioramas museum. Overall, 112 were involved program. Pre- post-program children’s knowledge ideas eleven selected are common Mediterranean areas tested....
