Dendrocopos Syriacus

Abstract Non-forest tree stands are important habitats for many species of birds in the agricultural landscape. They are also the main habitat of the Syrian Woodpecker Dendrocopos syriacus, whose numbers have been decreasing in recent years in some parts of Europe. Recognition of the habitat requirements of this species may help better planning of its protection in the context of the treed agricultural landscapes. During this study, the habitat preferences of the Syrian Woodpecker were determined in the agricultural landscape of South-Eastern Poland. A set of 12 habitat parameters of tree stands located in the breeding territories of the Syrian Woodpecker (n = 122) and in randomly chosen control areas (n = 122) located outside the range of the breeding territories of this species were characterized. The number and species diversity of trees was significantly higher in stands located in Syrian Woodpecker territories than in the random control areas. Stands occupied by breeding pairs also had trees of worse health condition and a larger proportion of fruit trees. The model best explaining the probability of the occurrence of the species indicates that the Syrian Woodpecker requires mainly the presence of tree stands with a greater species diversity of trees, as well as tree stands in worse health condition. When planning the protection of this species’ habitats in the agricultural landscape, the characteristics of non-forest tree stands noted above should be taken into account.

AbstractIn 2010, 16 macrofungi species were found in greenhouses of the Botanical Garden in Warsaw-Powsin. These included 8 species of lepiotaceous fungi and a few species known from warmer areas. For 3 species identified, which are new to Poland (Agaricus subrufescens, Leucocoprinus heinemannii, Marasmius teplicensis), a description is given, with drawings of their microscopic features and photographs. Species composition of macrofungi is compared in 5 complexes of greenhouses (Bayreuth, Graz, Jena, Paskov, Warsaw) in 4 countries from Central Europe. The total number of species in these 5 studies is 206, including 27 (13.2%) lepiotaceous fungi. The smallest number of species identified was in Warsaw (16). More than twice this number was recorded in Jena (33) and Graz (34), while the richest fungal biotas were in Bayreuth (79) and Paskov (88). Of the 16 species found in Warsaw, 8 were also found in other greenhouses. In the group of 33 species recorded in at least two complexes of greenhouses, the most abundant were the lepiotaceous fungi (39.4%) and mycenaceous fungi (15.1%). Leucocoprinus cepistipes and L. straminellus were recorded most often, in 4 of the 5 studied greenhouse complexes. CCA analysis demonstrated that the highest impact on species diversity is the area of greenhouses.

Source Of Error

Seamounts are important marine habitats that are hotspots of species diversity. Relatively shallow peaks, increased productivity and offshore locations make seamounts vulnerable to human impact and difficult to protect. Present estimates of seamount numbers vary from anywhere between 10,000 to more than 60,000. Seamount locations can be estimated by extracting large, cone-like features from bathymetry grids (based on criteria of size and shape). These predicted seamounts are a useful reference for marine researchers and can help direct exploratory surveys. However, these predictions are dependent on the quality of the surveys underpinning the bathymetry. Historically, quality has been patchy, but is improving as mapping efforts step up towards the target of complete seabed coverage by 2030. This study presents an update of seamount predictions based on SRTM30 PLUS global bathymetry version 11 and examines a potential source of error in these predictions. This update was prompted by a seamount survey in the British Indian Ocean Territory in 2016, where locations of two putative seamounts were visited. These ‘seamounts’ were targeted based on previous predictions, but these features were not detected during echosounder surveys. An examination of UK hydrographic office navigational (Admiralty) charts for the area showed that the summits of these putative features had soundings reporting ‘no bottom detected at this depth’ where ‘this depth’ was similar to the seabed reported from the bathymetry grids: we suspect that these features likely resulted from an initial misreading of the charts. We show that 15 ‘phantom seamount’ features, derived from a misinterpretation of no bottom sounding data, persist in current global bathymetry grids and updated seamount predictions. Overall, we predict 37,889 seamounts, an increase of 4437 from the previous predictions derived from an older global bathymetry grid (SRTM30 PLUS v6). This increase is due to greater detail in newer bathymetry grids as acoustic mapping of the seabed expands. The new seamount predictions are available at https://doi.pangaea.de/10.1594/PANGAEA.921688.
