The Wryneck

This book details the natural history and cultural symbolism of a most unusual woodpecker – a species that neither excavates nest holes in trees, nor bores into wood to find insect prey. The elusive Wryneck is best renowned for performing a twisting, writhing head and neck display when threatened, but this ground-breaking study reveals many more secrets of its behaviour and evolution. Detailed information is presented on the species' origins, taxonomy, anatomy, appearance, moult, calls, distribution, conservation status, habitats, movements, breeding, diet and relationships, along with a chapter on its closest relative, the Red-throated Wryneck. The text is richly illustrated throughout with high quality photographs as well as sound spectrograms. This all-encompassing and engaging account has been written for a wide audience, whether professional ornithologist, citizen scientist, amateur birder, woodpecker aficionado and simply someone who wishes to learn more about this curious and remarkable bird.

Měkkýši přírodních památek Kalábová a Kalábová 2 v CHKO Bílé Karpaty [Molluscs of the Kalábová and Kalábová 2 Nature Monuments in the White Carpathians PLA]

The Kalábová (K1) and Kalábová 2 (K2) Nature Monuments are located in the central part of the White Carpathians PLA near the village of Březová. Both monuments protect treeless wet grasslands and tufa forming spring fens, which were originally part of a larger wetland complex. A total of 51 species were recorded in K1 (47 terrestrial and two aquatic gastropods and two bivalves). Of these, 30 species (56%) are woodland dwellers that were recorded during the survey in 2000, shortly after the area was logged. In contrast, none of these species was detected during the recent survey in 2021. However, these species are widespread in the region and Nature Monuments surroundings and some are likely present also in the ecotones of the spring meadow and adjacent forest. Currently, hygrophilous and wetland dwellers dominate (9 spp.; 17%), followed by ubiquitous (7; 15%), open-ground (4; 8%) and aquatic species (4; 8%). At K2, 19 species were recorded, including 15 terrestrial and two aquatic gastropods, and two bivalves. The two most species-rich ecogroups were hygrophilous and wetland dwellers (5; 26%) and woodland dwellers (5; 26%), the latter were prevailing probably due to relatively recent deforestation between 2012–2014. Aquatic species were represented by four species (21%), followed by three ubiquitous (16%) and one open-ground (5%) species. The spring dweller Bythinella austriaca (NT) and the declining wetland umbrella species Vertigo angustior (VU; NATURA 2000) inhabited both localities in high densities. To maintain the favourable habitat conservation status of the reserves, the sites should be managed extensively by grazing or mowing.

Identification and documentation of wild plant species with ornamental potentials at Mount Prau, Central Java, Indonesia

Indonesia has diverse flora and fauna, and many species remain largely undiscovered. Documentation and identification of threatened wild ornamental species are increasingly difficult due to ongoing exploitation and land conversion. Mount Prau is one of the popular destinations in Central Java, Indonesia for tourism. Understanding plant biodiversity has enormous value for the economy, ecology, culture, science, and recreation. Our study is aimed to record the diversity and identify the flowering plant species in their native habitat at Mount Prau, Central Java, Indonesia. Our field surveys demonstrated that Mount Prau has abundant wild ornamental plants with wide diversity of taxa, growth habits, and forms. A total of 103 species representing 51 families and 95 genera are identified including trees, shrubs, herbs, and lianas. We also found that among the plant species found in Mount Prau, 24 have morphological characters suitable to be cultivated as ornamental flowers, and 12 as ornamental foliages, and 63 species are medicinal plants. The ornamental criteria of these species were based on the literature describing the morphological and unique characters of leaves and flowers that made them potential to be developed as ornamental plants. In this paper we have provided the current conservation status of the plant species identified and recommendations on their conservation. This study provides baseline data of species found in the Mount Prau areas, and this information could be helpful for further conservations efforts and initiatives.

Landscape Changes in Protected Areas in Poland

Land-Use Cover Changes (LUCCs) are one of the main problems for the preservation of landscapes and natural biodiversity. Protected Areas (PAs) do not escape this threat. Poland is among the European leaders in terms of the variety of landscapes and the share of an area designated as a protected area. However, as many as 78% of the habitats have poor or bad conservation status based on EEA reports. This article analyzes the LUCCs between 2000 and 2018 in various types of the Polish legal forms of nature protection areas and the European Natura 2000 network within the country. The research material was: the data of Corine Land Cover (CLC), the Central Register of Nature Protection Forms, and high-resolution layers, such as HRL and orthophotos. The results were compiled according to the CLC class and forms of protection. The matrix of transformations showed that the most frequently transformed CLC class was 312 (coniferous forest). It was transformed into class 324 (transitional woodland shrubs). The changes in PAs were usually smaller than in the surrounding buffer zones, which may indicate their effectiveness. The exception was the areas of the European Natura 2000 network. The scale of land-cover flows (LCFs) changed within particular forms of protected areas, though afforestation and deforestation predominating in all area types. National reserves and parks were the most stable in terms of land cover structures. However, human settlements increased around the protected areas, potentially increasing threats to their ecological integrity.

A new variety of Geranium ocellatum (Geraniaceae) from Uttarakhand, India

A new variety, Geranium ocellatum var. albiflorum, is described here from Tehri district of Uttarakhand state, India. The new variety is readily distinguished from G. ocellatum var. ocellatum by its central white spot at the petal base, dichasial inflorescence and peduncle length. A detailed description, photographs and conservation status are provided for the new variety. A key to the varieties of G. ocellatum is also provided.

Conservation Status of Forest Types Vary Greatly in Myanmar - the Most Forested Country in the Indo-burma Biodiversity Hotspot

Diverse forests with distinct forest types, harbor exceptional biodiversity and provide many ecosystem goods and services, making some forest types more economically valuable and prone to exploitation than others. The high rates of deforestation in Southeast Asia endanger the existence of such vulnerable forest types. Myanmar, the region’s largest forest frontier provides a last opportunity to conserve these vulnerable forest types. However, the exact distribution and spatial extent of Myanmar’s forest types has not been well characterized. To address this research gap, we developed a national scale Forest Type map of Myanmar at 20m resolution, using moderate resolution, multi-sensor satellite images (Sentinel-1, Sentinel-2 and ALOS-PALSAR), extensive field data, and a machine learning model (RandomForest). We mapped nine major forest types and developed a Conservation Status Score to evaluate the conservation status of the mapped forest types. Swamp, Mangrove, Dry Deciduous, Lowland Evergreen and Thorn forests were ranked as the five least conserved forest types. We also identified the largest remaining patch for each of the five least conserved forest types and determined their protection status to inform future forest conservation policy. In most cases, these patches lay outside protected areas indicating areas that may be prioritized for future conservation.

Twice lost, twice found: A new species of Gonolobus (Apocynaceae: Asclepiadoideae) with a reappraisal of the genus in the Yucatan Peninsula Biotic Province

Gonolobus is reassessed in the Yucatan Peninsula Biotic Province (YPBP). The genus consists of seven taxa in the area: six species and two subspecies. These include a taxon that we propose here as a new species and the treatment of G. yucatanensis as a subspecies of G. stenanthus and the new combination G. stenanthus subsp. yucatanensis is proposed. These two taxa are endemic to the YPBP. The other species are G. barbatus (for which we propose a lectotype), G. cteniophorus, G. fraternus, G. glaberrimus, and G. leianthus. The new species is G. caamalii Carnevali & R. Duno, restricted to the Yucatán state in Mexico and distinguished by its corolla lobes with a dark purple (almost black) longitudinal, callose band along the proximal 2/3 on the right side of the lobes and a 1.1–1.3 mm broad, annular, continuous dark purple-black band surrounding the gynostemium and corona at the base of the corolla lobes. It appears related to G. leianthus from southern Megamexico, a species from humid forests at higher elevations and that differs in its larger flowers with broader corolla lobes and a strikingly different color pattern in the flowers. The new species is described, illustrated, and discussed. Entries for all Gonolobus species from the YPBP include a brief discussion and specimen citations. The conservation status of the Gonolobus taxa endemic to the YPBP are assessed either as as Endangered (EN) or as Near threatened (NT). Distributional maps for all Gonolobus from the area covered are presented. Finally, we offer a key to Gonolobus of the YPBP.
