Abstract Global climate change is expected to shift species ranges polewards, with a risk of range contractions and population declines especially high‐Arctic species. We built distribution models for Svalbard‐nesting pink‐footed geese relate their occurrence environmental climatic variables, used the predict under warmer scenario. The most parsimonious model included mean May temperature, number frost‐free months proportion moist wet moss‐dominated vegetation in area. two variables are...
(1) The doubly-labelled water method was used in the first comprehensive study of penguin energetics throughout reproduction and moult season, comparing gentoo penguins (inshore feeding, sexually monomorphic, share breeding duties equally) with macaroni (offshore dimorphic, unequally shared). (2) While fasting during courtship incubation, macaronis (both sexes) female gentoos had field metabolic rates (FMR) 4.1 3.8 W kg^-1, respectively. Male also spending time at sea an FMR 7.5 kg^-1. for...
Abstract To achieve their conservation goals individuals, communities and organizations need to acquire a diversity of skills, knowledge information (i.e. capacity). Despite current efforts build maintain appropriate levels capacity, it has been recognized that there will be significant scaling-up these activities in sub-Saharan Africa. This is because the rapid increase number extent environmental problems region. We present range socio-economic contexts relevant four key areas African...
This study examined the habitat selected by swamp wallaby, Wallabia bicolor, red-necked Macropus rufogriseus, and common wombat, Vombatus ursinus. The habitats were unlogged forest three age classes of logged at 16 weeks 72 after a fire in November 1980 Mumbulla State Forest on south coast ofNew South Wales. Habitat selection was determined from decay-corrected dung counts. count for each species varied with topography class forest, demonstrating that logging had marked effect selected....
Abstract Many wildfowl species are declining and 34 out of 159 extant globally threatened, some which the subject specific conservation programmes. Here we investigate factors predict population trends across 154 Anseriformes. First show that there proportionately fewer populations in North America, Europe Australasia than south central Africa Asia. Second, use phylogenetic comparative analyses to test whether size, global range size ecological, life‐history sexually‐selected traits trends....
Research has highlighted a high frequency of skeletal asymmetries in horses. In addition, research into hoof shown that within bilateral pair, the with smaller angle is often subjected to greater loading. There been limited attention paid understanding compensatory mechanisms for horse; dynamic structure could potentially be acting capacity.To investigate relationship between morphometry forelimb segments and spread their incidence asymmetry.Ten measurements were taken from 34 leisure The...
Using a state, pressure, response framework, we provide an evidence-based reflection on environmental outcomes in Australia and New Zealand across the domains of climate change, biodiversity, freshwater marine management, emphasising role Indigenous business perspectives. Significant developments have occurred past 20 years through affirmation rights responsibilities. Responses to change tended emphasise passive risk management with unclear outcomes. Despite meeting biodiversity protection...
Abstract Patterns of habitat selection by American mink Mustela vison within foraging areas located on the shore, were studied in a coastal environment Scotland from November to March 1983/84, 1984/85 and 1994/95. The abundance prey intertidal zone was modelled relation abiotic environmental characteristics. Four factors found be important predictors abundance: position tidal zone, size rockpools, nature substratum presence fresh water streams. model used predict different shore. We then...
Understanding and predicting the likely consequences of anthropogenic disturbance on species ecosystems is a major prerequisite achieving sustainable use natural resources. It also key element in management sites with statutory designation. During planning decision‐making processes involving potential issues, land managers responsible authorities are often required to take account needs views diversity site user groups. The effects impacts can occur over range spatial temporal scales,...
Species distribution modelling is useful for addressing knowledge gaps poorly studied geographical areas by identifying potentially suitable habitats species across landscapes.This study was undertaken to identify containing wetland support actions aimed at the conservation of bird on Red Sea coast Kingdom Saudi Arabia (KSA).We used a maximum entropy approach build habitat suitability models 22 (gulls, shorebirds, and terns).Ten variables relating topography, habitat, latitude, complexity,...
Abstract Meeting the complex demands of conservation requires a multi-skilled workforce operating in sector that is respected and supported. Although professionalization widely seen as desirable, there no consistent understanding what entails. Here, we review whether how eight elements observed other sectors are applicable to conservation: (1) defined occupation; (2) official recognition; (3) knowledge, learning, competences standards; (4) paid employment; (5) codes conduct ethics; (6)...
Abstract Evidence‐based conservation has made some major steps forward in the last two decades. However, ‘landscape’ which evidence is generated, funded and disseminated still elements that will need to be further developed if UK's sector achieve its collective nature recovery goals. This paper articulates a shared vision of landscape 2035. It was by representatives 27 organisations involved across UK. Solution : authors identified range issues addressed allow base support guide efforts....
Estimates of the number breeding Lesser Black‐backed Gulls Larus fuscus at Tarnbrook Fell gullery, Lancashire, have been made from annual counts nests since 1981. During all these surveys, mean percentage which did not contain eggs has remarkably constant year to (54%± 1.9%). A study specific colony in 1992 showed that great majority “empty” subsequently receive eggs. 1993, a sample territory‐holding gulls was on 0.41‐ha plot investigate and quantify occurrence empty nests. Of 62 pairs...
We present the results of a census Manx Shearwaters Puffinus puffinus nesting on three Pembrokeshire islands Skomer, Skokholm and Midland (formerly Middleholm), Pembrokeshire, undertaken in 2018. The breeding population estimates were largely line with those made 2011–2013, but differed markedly from 1998; this difference seems to be due different methods used 1998 rather than any marked change size. Despite attempts refine estimation response rate call playback, error remains large,...
Abstract Capsule Population change in geese was assessed using an approach that requires a relatively small sampling effort. Aims During the 1999 breeding season survey carried out to determine if numbers of introduced Canada and re-established Greylag Geese southern Britain had changed since 1988–91 whether any occurred areas with previously high or low Goose densities. Methods A randomized stratified sample 246 tetrads from 24 156 covered between this area, as part New Atlas Breeding...
CapsuleBarnacle Geese restrict their movements to relatively few key sites and exhibit considerable variation in ranging behaviour. Aims To examine individual seasonal site fidelity, habitat use, range size foraging strategies of Barnacle Branta leucopsis. Methods The 18 male tagged two discrete areas were tracked for 3–6 months from late autumn until departure on the spring migration. Results Tagged geese concentrated feeding a small proportion apparently suitable habitat. moved...
Six adult male pink-footed geese ( Anser brachyrhynchus ), tagged with satellite transmitters, were tracked in Svalbard during the period of June–September 2003 and 2004. The purpose study was to describe movements staging periods individual post-breeding investigate a possible moult migration among Svalbard. All moved about 200 km east from their potential breeding (summering) areas western Spitsbergen. preferred moulting area island Edgeøya, where four staged prior southward autumn...
