Morimus asper funereus is a protected longhorn beetle species of community interest and conservation importance. It is included in Annex II of the Habitats Directive (as M. funereus) and protected under the Bulgarian Biodiversity Act. Although this saproxylic beetle is widespread in old-growth forests or well-structured woodlands in Central and Southeast Europe, its populations are currently threatened by forest practices, such as the removal of wood (branches and logs) (Hardersen et al. 2017). The species is with limited dispersal ability (due to lack of wings) and is very likely to possess very isolated and localized populations. In addition, M. asper funereus is of considerable interest from a taxonomic point of view with unclear taxonomic status for as much as Morimus asper is a morphologically highly variable species. At present, at least three species/subspecies of the genus Morimus are known from the territory of Bulgaria - Morimus asper, M. orientalis and M. vercundus bulgaricus (Danilevsky et al. 2016). Although, it is considered M. asper to be met almost everywhere in Bulgaria, its distribution is still not sufficiently known. We started a systematic and more intensive study on the species distribution in 2012 with the mapping of NATURA 2000 sites. Until the present study 54 localities from the literature had been known, after 562 new records have been added. The available information is organised in a database incorporated into the platform “SmartBirds Pro” - https://smartbirds.org (Popgeorgiev et al. 2015), part of which gives the possibility for registration of protected beetle species. In addition, the platform provides free access to all data (type, location, coordinates, date, observer). Here we present all available data for the species records, and its potential distribution and habitat preference for the territory of Bulgaria via deductive model, using the possibilities of GIS and MAXENT (Fourcade et al. 2014).

According to the Habitats Directive at European level there was constituted an ecological network entitled “Natura 2000” consisting of Special Areas of Conservation and Special Protection Areas. The “Natura 2000” is composed of sites which include natural habitats of community interest and community interest species habitats. The Special Areas of Conservation has been declared during two stages. During the first stage these were nominated as Sites of Community Importance. In the 6th North – Western Region there were identified 57 Sites of Community Importance (SCI) and 8 Special Protection Areas (SPA). Among the 6 counties of the 6th North – Western Region, the SCI are best represented in Maramureş county, and the SPA in Cluj county.

Extensive forest management aims at minimizing differences between managed and natural forests and at contributing to the conservation of endangered species such as the Atlantic-Gaspésie caribou. The decline of this isolated population was exacerbated by intensive forest practices, as the over-representation of regenerating forests supports high densities of bears and coyotes. These predators select such stands for the high availability of berries and browse suitable to alternative prey, especially moose. Our objective was to verify whether extensive treatments can provide suitable habitat characteristics for caribou. We compared the impacts of different intensive and extensive treatments on habitat attributes known to be selected by caribou, moose, and their predators. We sampled 291 sites in seven treatments and in mature coniferous forests (as the control). A partial canonical correspondence analysis highlighted which treatments maintain habitat attributes that are comparable with those found in mature forests, including some characteristics suitable for caribou such as a substantial biomass of arboreal lichen and a lower availability of resources for predators. Although being more suitable than the three intensive treatments tested, none of the four extensive treatments we studied provided similar habitat conditions to mature forest. Favouring extensive treatments could nevertheless be a relevant conservation compromise at the forest stand level, but their utility remains uncertain under the maximum sustainable yield paradigm as they impact a larger area.

LABURPENA: Habitaten Zuzentarauaren bidez, Natura 2000 Sarea sortu zen. Europar Batasuneko kontserbazio-eremu berezien sare ekologiko koherentea da, fauna- eta flora-espezie basatien zein Europar Batasunerako garrantzitsuak diren habitat naturalen kontserbaziorako. Estatu kideek zuzentarauaren 6. artikuluan xedatutako lan batzuk egin behar dituzte. Arau hori funtsezkoa da, Natura 2000 Sareko eremuen kudeaketari dagokionez. Lan honetan, ez zaio heltzen eremu horietan eragina izan dezaketen planen eta proiektuen ebaluazioa egiteko betebeharra aztertzeari, oso espezifikoa baita. Hain zuzen ere, Batzordeko erreferentziazko dokumentazioaren eta Europar Batasuneko Justizia Auzitegiaren jurisprudentziaren azterketa oinarri hartuta, honako hauek azaltzen saiatuko da lan honetan: zer jasotzen den babestu beharreko habitaten eta espezieen eskakizun ekologikoak betetzeko neurrietan, eta zein diren hartu beharreko neurri egokiak habitat eta espezie horiek hondamendi edo aldaketa nabarmenik ez izateko, eta zuzentarauaren helburuak betetzeko. RESUMEN: La Directiva Hábitats crea la Red Natura 2000, una red ecológica europea coherente de Zonas Especiales de Conservación existente en la Unión para la conservación de especies de fauna y flora silvestres y de hábitats naturales de importancia comunitaria. Los Estados miembros tienen que acometer unas tareas contempladas en el artículo 6 de la Directiva, precepto fundamental en cuanto a la gestión de los lugares Natura 2000 concierne. En este trabajo, sin abordar, por su especifidad, la obligación de evaluar planes y proyectos que puedan afectar a estos lugares, y analizando documentación de referencia de la Comisión y la jurisprudencia del TJUE, se intenta explicar en qué consisten esas medidas de conservación necesarias que respondan a las exigencias ecológicas de los hábitats y especies a proteger, así como las medidas apropiadas para evitar, en esos hábitats y especies, deterioros y alteraciones con efectos apreciables en los objetivos de la Directiva. ABSTRACT: The Habitats Directive established the Natura 2000 network, a coherent European ecological network of special areas of conservation that exists in the European Union for the conservation of species of wild fauna and flora and natural habitats of Community interest. Member states have to undertake some tasks contemplated in article 6 of the Directive, an essential provision as far as the management of Natura 2000 sites is concerned. This work, without tackling the duty to assess plans and projects that might affect these sites because of their specifity, and analyzing the documentation of reference of Commission and the caselaw of the European Court of Justice, tries to explain those necessary measures of conservation that meet the ecological requirements of habitats and species to protect together with the appropriate measures to avoid in those habitats and species, deteriorations and alterations in so far as such disturbance could be significant in relation to the objectives of the Directive.

ABSTRACT The action framework at the European Union level for the protection of biodiversity was established based on the Habitats Directive (92/43/EEC) and the Birds Directive (79/409/EEC). One main element of the future implementation of these Directives in Croatia is the establishment of a Natura 2000 network of special protection sites, a network which should rely on a specific monitoring plan at national level for each species of community interest. In this context, the present study proposes a set of monitoring elements for Barbus meridionalis for the Croatian Continental Biogeographical Region. The proposal is based on seven main criteria: proximity of national border, high quality populations, habitats which should be ecologically reconstructed, key habitats/sectors with high importance for connectivity, point sources of industrial pollution, areas/sectors influenced by diffuse sources of agricultural pollution, and areas/sectors influenced by habitat modifications.

Hares were introduced into Australia early in the period of European settlement. This study examined historical issues of newspapers and other historical sources to ascertain the number of importations, the number of hares landed alive, their destinations, relevant habitat characteristics at the sites of the releases, and whether the propagules became established and spread. Forty shipments were identified, and one or more live hares were landed from 27 of those shipments, totalling ~86 live hares, and resulted in the establishment of 10 populations of hares. The climate and the grasses at the known release sites were suitable for Lepus europaeus and predators were rigorously suppressed, which, acting together with the wealth, power, influence, and determination of the proponents of the importations, made establishment of hares in Australia almost certain. However, 11 of the hares landed alive were almost certainly L. nigricollis, and the fates of seven of those hares are not known. There are populations of hares in Australia at sites suited to L. nigricollis but not L. europaeus on the basis of climate and availability of C4 grass types, and the taxonomic status of those hares should be examined.

Abstract Keeled Plump Bush-cricket Isophya costata is one of ten orthopteran species of European Community interest (Annex II and IV of Habitats Directive), endemic to the Pannonian Basin in Central Europe. It was discovered for the first time in Slovakia in June 2017, in southwestern area of the country (the site Devínske jazero, 48.2722°N / 16.9404°E, 134 m a.s.l.), in continental flooded meadows. The presence of the species in this new site is copying the northern edge of its area. New data of species distribution, its habitat, accompanying orthopteran species are described and main threats and conservation measures of the species are discussed.

Larvae of the two European species of the genus Pyrochroa (P. coccinea and P. serraticornis) are redescribed, for the first time based on Italian samples, and new relevant and distinctive characters have emerged from P. serraticornis. Particularly, the presence of a single urogomphal pit between urogomphi (representing a new condition for the entire family), and new characters of mandibles, open new questions about the current taxonomic status of the European species.

The Alaska Hare (Lepus othus Merriam 1900) is the largest lagomorph in North America but remains one of the most poorly studied terrestrial mammals on the continent. Its current distribution is restricted to western Alaska south of the Brooks Range, but historical accounts from north of the Brooks Range (the North Slope) have led to confusion over its past, present, and predicted future distributions. To determine if L. othus occurs or historically occurred on the North Slope, we surveyed museum collections, vetted observational accounts, and produced a spatial distribution model based on the resulting georeferenced records. We located a historic specimen long presumed lost that suggests the occurrence of L. othus on the North Slope as recently as the late 1800s. We also uncovered evidence of L. othus and (or) Mountain Hare (Lepus timidus Linnaeus 1758) on several islands in the Bering Sea, raising the possibility of recurring gene flow between these closely related species across seasonal ice connecting Asia and North America. While our results paint a more complete picture of the current distribution of L. othus, persistent uncertainties surrounding its taxonomic status and potential northward range shift onto lands reserved for oil and gas development call for additional study.

The habitat of the several territories in Ciudad Real (Castilla-La Mancha, Spain) are studued through the and mapping (scale 1:10.000) and vegetation analysis. The distribution and surface of the habitat presents in the Sites of Community Interest (SCIs), as well as pressures, threats, trends, and state of conservation are described. These site contributes significantly to the maintenance or restoration at a favourable conservation status of a natural habitat type or of a species of community intesess.These specially protected areas are part of the Natura 2000 network. We discuss the diversity of forest habitats characterized by species of the genus Quercus L., focusing only on the plant communities in the Habitats Directive 92/43/EEC of 1992, regarding the conservation of fauna and flora and habitats of interest owing to their endemic or rare character. Habitats and species must be studied in combination to ensure the maximum reliability of the results. We concentrate on habitats with low representation in the territory as a consequence of their rarity or endemicity. We study the following habitats of special interest: 9230—Mediterranean-Ibero-Atlantic and Galaico-Portuguese oak woods of Quercus robur and Quercus pyrenaica; 9240—Iberian oaks of Quercus faginea and Quercus canariensis; 9320—Thermomediterranean forests of Olea and Ceratonia (Iberian Peninsula, Balearic and Canary Islands); 9540—Mediterranean pine forests of endemic Pinus pinaster (Pinus pinaster subsp. acutisquama); 9560—Endemic forests with Juniperus spp.; 5210. Arborescent scrub with Juniperus spp.

Numerous amphibian species are declining because of habitat loss and fragmentation due to urbanization of landscapes and the construction of roads. This is a mounting threat to species restricted to habitats close to urban areas, such as agricultural wetlands in North East Asia. The Suweon treefrog (Dryophytes suweonensis) falls into the list of species threatened with habitat loss and most populations are under threat of extirpation. Over the last decades, sub-populations have become increasingly disconnected and specifically the density of paved roads has increased around the only site connecting northern and southern Seoul populations. We surveyed this locality in Hojobeol, Siheung, Republic of Korea in 2012, 2015 and 2019 to first confirm the decline in the number of sites where D. suweonensis was present. The second objective was to analyze the habitat characteristics and determine the remaining suitable habitat for D. suweonensis through a species distribution model following the maximum entropy method. Our results show that rice paddy cover and distance from the paved road are the most important factor defining suitable habitat for D. suweonensis. At this locality, uninterrupted rice paddies are a suitable habitat for the species when reaching at least 0.19 km2, with an average distance of 138 ± 93 m2 from the roads. We link the decrease in the number of sites where D. suweonensis is present with the decrease in rice paddy cover, generally replaced by localized infrastructures, greenhouses and habitat fragmentation. Rice paddies should remain connected over a large area for the protection of the remaining populations. In addition, habitat requirements should be integrated in the requisites to designate protected areas.
