The general situation concerning the contribution that industrial development has made to the conservation of wildlife in Britain is reviewed. Two major types of site have been identified, namely discrete and linear, each being divided into a number of categories, with further subdivisions depending upon the nature of the site: for example, used or disused (canals, railways, etc.) or wet or dry (gravel pits, clay pits, etc.).The wildlife value of a representative sample of sites of each type is described qualitatively. It is argued that industrial development produces areas which are often richer in wildlife than much of the remaining rural or urban environment. This results from the existence of ‘wilderness areas’ within industrial complexes, from the creation of new habitats, from the passage of time, and from the protection given against public access and against intensive agricultural, forestry, and landscape, management. The linear systems are seen as forming a network of ‘wildlife corridors’ linking together discrete sites, thus providing reservoirs for the colonization of new habitats and enabling wildlife to survive in close proximity to intensively used urban and rural land. Many ‘industrial sites’ provide facilities for field studies, environmental trails, and environmental education, as well as forming the basis of country or linear parks. They also enable many rare species to survive, and probably prevent many of the common species from becoming less frequent.

The paper presents the activities of the Scientific Library of the Siberian Federal University on the development and implementation of the project “Creation of a Scientific and Educational Geographical Library in SFU”. This project was launched jointly with the Russian Geographical Society. The goal of the project is to form and provide users with high-quality information and educational resource on the profile and topics of the main directions of development of geographical sciences, popularization of geographical knowledge. The activity of the library in the field of formation of unified information scientific and educational space, in the context of the main directions, reflecting the development strategy of the SibFU is analysed. The study of the Arctic is one of the priority tasks of the university. The Arctic vector plays an important role in creating a new library model, in the context of the formation of information resources: the works of SibFU scientists related to the study of Siberia and the Arctic, and providing public access to the accumulated knowledge. The basis of this collection is a unique collection of documents by S. B. Slevich, Doctor of Geographical Sciences, Professor, Academician of the Russian Ecological Academy. The paper discusses the activities for the implementation of the project. The library forms a collection of documents on topics - indigenous peoples, ecology of the Far North, industrial development of northern territories, construction on permafrost and digitizes rare publications. A geographic reading room has been opened to organize access to resources. Together with the Presidential Library. B.N. Yeltsin annually held a scientific and practical seminar “Arctic Day at the Siberian Federal University”. Ways of further work to promote the project have been identified.

Drosophila suzukii (spotted wing drosophila, SWD) is a pandemic quarantine pest that attacks mostly red fruits. The high number of life cycles per year, its ability to rapidly invade and spread across new habitats, and highly polyphagous nature, makes this a particularly aggressive invasive species, for which efficient control methods are currently lacking. The use of native natural predators is particularly promising to anchor sustainable and efficient measures to control SWD. While several field studies have suggested the presence of potential predatory species in infested orchards, only a few confirmed the presence of SWD DNA in predators’ gut content. Here, we use a DNA-based approach to identify SWD predators among the arthropod diversity in South Europe, by examining the gut content of potential predator specimens collected in SWD-infested berry fields in North Portugal. These specimens were morphologically identified to the family/order, and their gut content was screened for the presence of SWD DNA using PCR. New SWD predatory taxonomical groups were identified, as Opiliones and Hemerobiidae, in addition to known SWD predators, such as Hemerobiidae, Chrysopidae, Miridae, Carabidae, Formicidae and Araneae. Additionally, the presence of a spider family, Uloboridae, in the orchards was recorded for the first time, posing this family as another SWD-candidate predator. This study sets important bases to further investigate the potential large-scale use of some of these confirmed predator taxa for SWD control in South Europe.

The assessment of habitat selection and temporal patterns of activity rhythms is paramount for wildlife conservation. Studies on behavioural ecology of wild mammals are particularly challenging in tropical areas, mostly when involving rare or elusive species. Despite being a common species in Italy, the crested porcupine Hystrix cristata is threatened of extinction throughout most of its sub-Saharan range. All available information on the ecology of this species has been collected in Italy, whereas no data is present in the scientific literature on spatiotemporal behaviour of this large rodent in Africa. In this work, we attempted to determine habitat selection and temporal patterns of activity rhythms of the crested porcupine in northern Benin and neighbouring countries, through intensive camera-trapping. We collected a total of 146 records of crested porcupine, 91 in the dry season (October-March) and 55 in the rainy season (April-September). Porcupines used most habitats in proportion to their local availability, while selecting rock outcrop formations (possibly used as shelter sites) and avoiding open areas, wetlands and gallery forests. A mostly nocturnal behaviour was confirmed throughout the year, with some diurnal activity at the start and at the end of the rainy season. The importance of rains in determining birth peak has been also showed, with juvenile individuals always observed at the start and at the end of the rainy season. Full moon always inhibited activity of this large rodent, most likely evolved as an antipredatory behaviour to limit encounters with potential predators (common leopard Panthera pardus, spotted hyaena Crocuta crocuta and honey badger Mellivora capensis) and humans. Poaching pressure towards porcupines in West Africa is strong. Porcupines are killed for the traditional medicine, for their meat and because they are widely considered as a crop pest. This assessment should therefore be used as a basic tool to design conservation plans to preserve this rodent species in its native range.

The past, or the perception of the past, plays a pivotal role in the formation of modern policies on land-use, since the rhetoric of conservation favours the protection of ‘ancient’ or ‘pristine’ landscapes, whilst the focus on economic or environmental sustainability has led to the endorsement of apparently long-lived ‘indigenous’ practices, especially where these appear to have permitted extended periods of cultivation whilst conserving local soil, water, and forest resources. Focusing on examples of locally developed intensive agriculture from Kenya and northern Tanzania, this chapter aims to highlight how the history of landscape management in these areas—although still poorly understood—continues to be cited within developmental and conservationist debates. It will outline how a combination of archaeological, historical, and palaeoenvironmental research might be employed to produce a more complete understanding of these agronomies, and argues that work of this kind is essential to qualify the historical assumptions that have been used to justify external intervention. The invocation of historical arguments in support of either economic intervention or wildlife conservation is not a recent phenomenon, but the critical appraisal of such arguments has gained momentum over the last two to three decades. It is by no means a coincidence that this is also the period that has seen a rise in interest in the precepts of ‘historical ecology’ (e.g. Balée 2006; Crumley 1994) and in resilience theory (e.g. Walker et al. 2004), both of which emphasize the need to study social, economic, and environmental factors from a long-term historical perspective in order to fully understand the relationships between them in any given place or time, and both stress the importance of seeing modern landscapes and resource exploitation strategies as legacies of former periods of land-use. More recently, a resurgence in interest in world systems theory—itself formerly influential on developmental thinking via dependency theory (e.g. Frank 1969)—raises similar themes through the notion that most if not all local economies have been influenced by their interaction with broader webs of trade relations at regional and global scales for several centuries (e.g. Hornberg and Crumley 2007).

Abstract Field trials in which paired observers were used and indoor simulations in which recorded bird songs were used indicated that, as the number of singing birds audible from a listening station increased from 1 to 4, the fraction of them recorded by observers declined by up to 50%. This reduction in efficiency violates one of the basic assumptions of any index-that the proportion of animals detected remains constant-and could cause surveyors who rely primarily on auditory cues to underestimate changes in population density by up to 25% for common species and 33% for abundant species. The change in efficiency, which is best regarded as measurement error, cannot be detected by a statistical examination of the data and thus may pass undetected in many field studies. It seems unlikely that any general procedure for "correcting" the error would be reliable. The results indicate that singing bird surveys of common species should be supplemented by other methods if accurate estimates of changes in density are needed. A general conclusion of the study is that whenever animals "compete" for a place in the survey, for example by filling up traps or suppressing one another's songs, then the index tends to underestimate a change in density. If efficiency increases with density, then the survey tends to overestimate a change in density. If the sign of the bias can be determined, the survey can be used to provide a minimum or maximum estimate of a change in density even if the magnitude of the bias cannot be estimated.

A series of studies is reported in which a number of human factors considerations were investigated in the design of a keypad entry system for Telidon public access terminals. Initial studies evaluated subjects' preferences with simulated keypads upon which subjects performed simulated Telidon tasks. Subsequently, working prototypes were developed of the two most preferred keypads. User performance and preference were evaluated in a series of field studies. It was found that preference measures for the prototypes closely approximated data derived using the simulations, indicating validity of this inexpensive method of design testing.

Biodiversity continues to decline in Australia despite significant effort by government, industry and concerned citizens. In this essay the author draws upon his >30 years of experience at the sharp end of natural resource management to consider some factors that may be contributing to the relative lack of progress. While national parks and reserves form a small part of the overall Australian landscape their importance in the battle to retain biodiversity is undeniable. However, rigidity of thinking on the part of park managers has limited the support base for parks and thus their potential in leading integrated landscape management at the all-important local level. The rise of animal libertarianism is further impacting on the ability of parks and wildlife managers to make rational decisions based on the best scientific advice. Animal libertarianism, influential in our western, primarily urban-based society, causes significant problems in wildlife conservation. Anthropomorphic concepts of rights have little application in the animal world and contribute even less to the conservation of species.

Riassunto - La risposta dei lepidotteri diurni agli effetti del fuoco è estremamente variabile. Per approfondire le attuali conoscenze sull’argomento in italia sono state indagate 5 aree boscate lombarde collinari o montane percorse dal fuoco. La ricchezza in specie di farfalle diurne e la loro abbondanza relativa sono state registrate nel corso di campionamenti condotti mensilmente tra giugno e agosto 2000 lungo due transetti campione limitrofi in ogni area oggetto di studio: uno danneggiato dal fuoco e l’altro (di controllo) mai o poco interessato dall’incendio. Per ogni specie rilevata sono state prese in considerazione le preferenze di habitat. Dalla ricerca è emerso sostanzialmente che in aree boscate di non elevato pregio naturalistico, come quelle indagate, l’azione del fuoco può costituire un pericolo reale per specie nemorali e non comuni (es. Lasiommata achine, Limenitis populi), mentre può originare ambienti nuovi per specie non esclusivamente forestali o comunque svantaggiate dall’infittirsi dei boschi (Leptidea sinapis, Melitaea athalia), finendo quindi per costituire in alcuni casi un elemento di arricchimento delle popolazioni di farfalle diurne locali, anche se limitato per lo più a specie di ambienti transitori di interesse conservazionistico non particolarmente elevato. L’utilizzo dell’indice di Sørensen per valutare la somiglianza specifica tra ambiente incendiato e di controllo non ha fornito risultati significativi. interventi di gestione post-incendio in aree forestali come quelle oggetto di studio, oltre a tener presente considerazioni di ordine generale sulle cause di minaccia dei lepidotteri diurni in italia, si dovrebbero basare sui risultati di ulteriori indagini di cui vengono indicate le modalità eventualmente da adottare a partire dal quadro conoscitivo iniziale fornito dalla presente ricerca.Abstract - Butterflies and fires: a survey in forests of Lombardy (Lepidoptera Hesperioidea, Papilionoidea). The response of butterflies to the effects of fire is extremely variable. in order to improve the state-of-the-art knowledge on the subject in Italy, five wooded areas interested by fire in the region of Lombardy (Northern italy) have been investigated. Butterfly richness and relative abundance have been recorded through monthly surveys carried out between June and August 2000. For each area, two neighboring transects have been analyzed, respectively damaged and not damaged by fire. The latter was used as a reference for comparison. The habitat preferences have been analyzed for each sampled species. Results show that the action of fire can work as a real danger for nemoral and non common species (e.g., Lasiommata achine, Limenitis populi) in wooded areas of poor ecological value. on the other hand, fire can create new habitats for species which are not exclusively nemoral or - more generally- for butterflies which need open habitats and cannot colonyze forests (e.g., Leptidea sinapis, Melitaea athalia). The Sørensen index has also been used to evaluate the specific similarities between the investigated areas, but it has not given significant results. The findings of this research can be used to plan ad-hoc post-fire management actions in forestal areas as a complement to the general considerations on the causes of threat of diurnal Lepidoptera in italy.

AbstractIsland populations may have a higher extinction risk due to reduced genetic diversity and need to be managed effectively in order to reduce the risk of biodiversity loss. The Eurasian red squirrels (Sciurus vulgaris) in the south of England only survive on three islands (the Isle of Wight, Brownsea and Furzey islands), with the Isle of Wight harbouring the largest population in the region. Fourteen microsatellites were used to determine the genetic structure of red squirrel populations on the Isle of Wight, as well as their relatedness to other populations of the species. Our results demonstrated that squirrels on these islands were less genetically diverse than those in Continental mainland populations, as would be expected. It also confirmed previous results from mitochondrial DNA which indicated that the squirrels on the Isle of Wight were relatively closely related to Brownsea island squirrels in the south of England. Importantly, our findings showed that genetic mixing between squirrels in the east and west of the Isle of Wight was very limited. Given the potential deleterious effects of small population size on genetic health, landscape management to encourage dispersal of squirrels between these populations should be a priority.

Abstract Urban wildlife organizations—which include groups focused on wildlife rehabilitation, rescue, removal, advocacy, education, and conflict resolution—have typically been viewed as out of step with the goals of wildlife conservation because of their focus on encounters with individual nonhuman animals, common species, and degraded habitats. The recent shift by large conservation NGOs toward a “humans and nature together” framework, because of its focus on urban natures, has brought the field into discursive relation with urban wildlife organizations. Drawing on a case study of four wildlife organizations in an urban center, this research explores their discourse about human-wildlife relationships in the city, and the challenges and opportunities presented by their emergent intersections.
