Il Parco Regionale della Maremma è una area protetta di 8902 ha nel settore costiero centrale della provincia di Grosseto, Toscana meridionale. Gli habitat che rappresentano l’area protetta possono essere così brevemente descritti: foce del fiume Ombrone e zone umide della Palude della Trappola; Monti dell’Uccellina (cima più elevata: Poggio Lecci, 417 m s.l.m.); un ampio comprensorio interno e pianeggiante dove coesistono attività zootecniche e coltivazioni agricole. Lo sviluppo costiero raggiunge i 25 km circa. Sono presenti 6 Siti della Rete Natura 2000 classificati come ZSC − Zona Speciale di Conservazione − secondo la Direttiva “Habitat” 92/43/ CE e/o come ZPS − Zona di Protezione Speciale − secondo la Direttiva “Uccelli” 2009/147/CE. La maggior parte dell’area presenta una scarsa rete viaria e limitati insediamenti umani con copertura boschiva in larga parte dovuta a formazioni vegetali sclerofilliche mediterranee. In questo lavoro viene presentato un elenco commentato degli uccelli noti per l’area protetta a partire dalla sua istituzione avvenuta il 05/06/1975 sino al 31/12/2018. In totale, le specie di Uccelli rilevate sono 295 (62,1% delle specie della Toscana ed il 52,5% delle specie note in Italia), mentre le specie nidificanti certe o probabili in tempi recenti (2008-2018) sono 84. Le specie di interesse comunitario presenti nell’Allegato I della Direttiva “Uccelli” 2009/147/CE sono 88, mentre quelle classificate come SPEC 1-3 “Species of European Conservation Concern” sono 33. L’area, con le zone umide “Bocca d’Ombrone” e “La Trappola” comprese nella Macrozona “Maremma Grossetana”, ricade all’interno della qualifica di sito di importanza internazionale per lo svernamento di Anser anser e Mareca penelope; inoltre è sito di importanza nazionale per Mareca strepera, Anas crecca, Anas acuta, Spatula clypeata, Ardea alba, Platalea leucorodia, Phoenicopterus roseus, Recurvirostra avosetta, Pluvialis apricaria, Calidris alpina, Vanellus vanellus, Gallinago gallinago, Numenius arquata, Tringa erythropus e Tringa totanus. L’area protetta è di importanza per specie nidificanti in Direttiva 2009/147/CE legate agli specchi lacustri costieri e agli spazi marini, ad incolti, pascoli, così come a zone con vegetazione arborea e arbustiva sparsa su affioramenti rocciosi, margini di boschi, ambienti parzialmente allagati ed ai litorali sabbiosi, quali ad esempio, con dati minimi, Pandion haliaetus (1 coppia), Burhinus oedicnemus (7-8 coppie), Charadrius alexandrinus (1 coppia), Caprimulgus europaeus (25 coppie), Coracias garrulus (13-15 coppie), Lanius collurio (1-5 coppie), Lullula arborea (10 coppie) e Anthus campestris (6-7 coppie). Dal 2015 si segnala il consolidamento della nidificazione di Ardea cinerea, rilevandone per la prima volta la riproduzione come garzaia.

The Impact

AbstractThe prevalence of human cercarial dermatitis (HCD) caused by bird schistosomes appears to be increasing in France, in light of the impact of tourism combined with high densities of wild aquatic hosts in freshwater areas. The present work expands our knowledge of schistosome systematics by including samples of bird schistosomes collected from their natural hosts in France. Heads (318) and viscera (81) of aquatic birds belonging to 16 species from five orders, collecting during the hunting seasons or found dead, were autopsied for nasal and visceral schistosomes. Eggs and/or adults were analysed by molecular methods using the D2 domain and the second internal transcribed spacer (ITS-2) region of rDNA to determine species. Even if nasal eggs were polymorphic according to the host, all haplotypes were similar to that of Trichobilharzia regenti. Marked diversity of visceral species was observed. Final hosts under natural conditions were reported. For the first time, Trichobilharzia franki is reported in its natural bird hosts, Anas platyrhynchos, Anas crecca, Aythya fuligula and Cygnus olor. We also identified T. szidati in A. crecca and Anas clypeata. Bilharziella polonica was found in six species of aquatic birds, including Grus grus. This finding is the first record of bird schistosomes in this aquatic bird. Three new taxa of visceral schistosomes in Anser anser are strongly suspected according to their haplotypes. Futhermore, a new haplotype of visceral schistosomes isolated in Cygnus olor and similar to Allobilharzia visceralis was identified.

Diversity Metrics

Around a yearly cycle (August 2011 - July 2012), we studied the assemblages of waders (Aves Charadriiformes) occurring in a Mediterranean remnant wetland, obtaining a set of diversity metrics. Mean total abundance shows a complementary pattern when compared to species richness and diversity: the highest values of mean total abundance were observed in December-January, due to high dominance of only one very abundant and gregarious species (the lapwing Vanellus vanellus). On the contrary, in this period, species richness and diversity showed the lowest values. These last metrics were highest in values during the April-September period when a large number of species of conservation concern utilize muddy areas as trophic and stop-over sites, due to the seasonal water stress. The highest values in species turnover index were observed between December-January and February-March when passage migrants (high richness, low abundance) substitute the wintering species (low richness, high abundance). Our data highlight that, in Mediterranean remnant wetlands, strategies should be addressed to increase the muddy suitable areas in the April-September period in order to maximize species richness and diversity. In fact, in these months these habitats host pre- and post-breeding migrant waders of conservation concern.

Migrations of Waders (Charadrii) in the Middle Odra Valley (W Poland) Studies were conducted in 1994-2005, in the middle Odra valley (western Poland), between localities: Bytom Odrzański and Kunice (155 km). During research 1535 controls of different parts of valley were made. There were recorded 26 Charadrii species. Regular occurrence and migrations were observed only for a few of them: Little Ringed Plover (Charadrius dubius), Golden Plover (Pluvialis apricaria), Lapwing (Vanellus vanellus), Ruff (Philomachus pugnax), Common Snipe (Gallinago gallinago), Curlew (Numenius arquata), Redshank (Tringa totanus), Grenshank (T. nebularia), Green Sandpiper (T. ochropus), Wood Sandpiper (T. glareola) and Common Sandpiper (Actitis hypoleucos). There were a few observations of rare in Poland - Sociable Plover (Vanellus gregarius) - or usually uncommon inland species - Oystercatcher (Haematopus ostralegus), Great Snipe (Gallinago media), Bar-tailed Godwit (Limosa lapponica) and Whimbrel (Numenius phaeopus). Two features characterizing the waders' passages in the Lubusian part of Odra valley can be told. Firstly, the abundance of migrating birds is usually lower than in other areas, especially when comparing autumn numbers to big inland reservoirs and some ponds complexes. Secondly, the middle part of Odra valley plays more important role during spring than during autumn passage, especially for Lapwings and Golden Plovers.

Abstract In 2009, in the Special Protection Area Natura 2000 ‘Grądy Odrzańskie’ in Czernica and Siechnice counties, Wrocław district, 95 breeding bird species were recorded. For 33 of them, maps of distribution of their breeding pairs are presented and for the remaining a relative abundance was estimated based on line transect method. In 2009, the following species were recorded in the study area for the first time: Cygnus olor, Crex crex, Upupa epops, and Picus canus. On the other hand, 11 species recorded in 1978-87 as breeding in the study area (Ciconia nigra, Pernis apivorus, Milvus migrans, Milvus milvus, Falco tinnunculus, Gallinago gallinago, Limosa limosa, Tringa totanus, Riparia riparia, Anthus campestris, Phoenicurus phoenicurus) were not recorded again in 2009. It has been shown that Saxicola torquata, Ficedula albicollis, Corvus corax and Remiz pendulinus have increased in numbers. The following species recorded in 2009 as breeding in the the study area: Cygnus olr, Ciconia ciconia, Circus aeruginosus, Crex crex, Alcedo atthis, Dryocopus martius, Picus canus, Dendrocopos medius, Lulula arborea, Sylvia nisoria, Ficedula albicollis, Lanius collurio and Emberiza hortulana are included in Annex 1 of the Bird Directive.

Wetlands Conservation

Abstract Wetlands are among the most endangered ecosystems worldwide with multiple direct and indirect stressors, especially in human-altered areas like intensive agricultural landscapes. Conservation management and efforts often focus on species diversity and charismatic taxa, but scarcely consider habitats. By focusing on a complex formed by 107 permanent wetlands at 18 Natura 2000 sites in the Emilia-Romagna region (northern Italy), the patterns of habitats of conservation concern were investigated and the concordance with threatened species patterns was analysed. Wetlands were characterised in terms of morphology, connectivity, land use and management as drivers of assemblage and richness patterns of habitats. Our results showed a strong concordance between the distribution and richness patterns of both habitats and threatened taxa (birds, mammals, amphibians, reptiles, fish, invertebrates, and plants). Thus, habitats seem an effective proxy of species patterns. The variables related with perimeter, environmental heterogeneity and presence of water bodies were the most important ones associated with habitat richness patterns. The presence of aquatic systems (measured as the percentage of wetland area occupied by an aquatic surface) and their position in the hydrographic network were associated mostly with habitats distribution. Low richness wetlands (in habitat terms) were not complementary as no new habitat types were supported. The results stressed the relevance of wetlands with wide water body perimeters composed of diverse systems as being key for biodiversity conservation in a simplified agricultural matrix. Integrating habitat- and species-based perspectives seems a promising field and may provide a rapid assessment tool to acquire effective information for wetlands conservation and assessment.

Abstract The aim of the study done in 2011 and 2012 was to identify the number of breeding bird species, to provide population estimates as well as to evaluate the conservational importance of Škocjan Caves Park for birds. Common bird species were surveyed using the territory mapping method. Rare species and nocturnally active species were surveyed using species-specific methods: observation, the playback method and the line transect method. 81 species were registered, 49 of which bred within the boundaries of the Park. The most abundant breeding species were Blackcap Sylvia atricapilla (260-320 breeding pairs), Robin Erithacus rubecula (250-310 breeding pairs), Blackbird Turdus merula (230-280 breeding pairs), Chaffinch Fringilla coelebs (230-280 breeding pairs) and Marsh Tit Poecile palustris (200-240 breeding pairs). Qualifying species for the Special Protected Area (SPA) Kras (SI5000023) also bred within the Park: Peregrine Falcon Falco peregrinus, Nightjar Caprimulgus europaeus, Scops Owl Otus scops and Woodlark Lululla arborea. Eagle Owl Bubo bubo was also registered, but breeding attempts during the study period were unsuccessful due to the negative influence of several factors. One of the largest colonies of Alpine Swifts Apus melba, a rare and localized species in Slovenia, is also of conservation concern.

Abstract In the Netherlands, breeding populations of wader meadow birds are in sharp decline. One possible cause is that breeding areas are becoming less open because of tall trees and other factors. The effects of tree lines are generally studied by means of transversal studies spanning a short period of time. We report on a longitudinal field study from 1993 to 2010 into the breeding densities of Eurasian Oystercatcher (Haematopus ostralegus), Northern Lapwing (Vanellus vanellus), Black-tailed Godwit (Limosa limosa) and Common Redshank (Tringa totanus) in the Demmerik polder, the Netherlands. One part of this polder, a nature reserve, has an older tree line, while two agricultural parts are divided by a newly developing tree line. As the tree line in the agricultural parts was developing, foraging families of Greylag Goose (Anser anser) showed a strong increase in only one of these parts during the breeding season. During the same period, the density of avian predators also increased in the whole polder. Analysis shows waders avoid trees in both situations: with an existing tree line (a static situation) and with a growing tree line (a dynamic situation). We investigated the possible role of geese and avian predators in explaining the decline in density of breeding wader meadow birds, by systematic comparison of several different models. In these models, the effect of the growing tree line has the greatest impact on breeding meadow birds. Models with geese describe the trends of breeding wader meadow birds better than those including avian predators, but since these two variables, geese and avian predators, are confounded, no definitive conclusion can yet be drawn. Potential explanations of and functional mechanisms behind the strong decline in breeding meadow bird populations in this area are discussed.

По результатам исследований 1976-2018 гг. (1,1 тыс. локальных наблюдений и количественных учетов) рассмотрен видовой состав, распространение, численность, характер и сроки пребывания куликов в горном Крыму. Выявлено 36 видов, не отмечены указанные ранее Charadrius hiati cula. Pluvialis apricari а и Glareola nordmanni. Гнездятся 7 видов (Burhims oedicnemus. Charadrius dubius. I anellus vanellus. Himantopus himantopus. Tringa totanus. Actitis hypoleucos. Scolopax rusticola), в том числе 4 в предгорьях, 5 на востоке Южного берега Крыма и 3 в области Главной гряды. Большинство видов распространено спорадически и малочисленно по причине дефицита подходящих местообитаний. Обычен и широко распространен Charadrius dubius. В миграционные периоды встречается 35 видов (31 весной и 26 осенью); пики видового разнообразия мигрантов наблюдаются в третьей декаде апреля и третьей декаде августа. На летних кочевках обычны Actitis hypoleucos и Tringa ochropus. Зимуют 8 видов - Vanellus vanellus. Tringa ochropus. T. totanus. Calidris alpina, C. canutus. Lymnocryptes minimus. Gallinago gallinago. Scolopax rusticola, последний обычен. Со второй половины XX века в фауне куликов Крыма в общем и горной его части в частности произошли существенные изменения. Обнаружено II ранее не зарегистрированных видов: 10 мигрирующих (Vanellochettusia leucura. Arenaria interpres. Haematopus ostralegus. Tringa stagnati lis. Xenus cinereus. Calidris ferruginea, C. alba. Limicola falcinellus. Numenius phaeopus. Glareola pratincola) и 1 зимующий (Calidris canutus). Подтверждено пребывание 8 видов, ранее отмеченных только в XIX - начале XX века; 2 вида (Himantopus himantopus. Tringa totanus) впервые обнаружены на гнездовании и 3 вида (Vanellus vanellus. Tringa nebularia. T. totanus) - во время осенней миграции.
