Volumes, dredged area measurements and estimated contaminants of material disposed at licensed offshore sites around the UK coast from 2000 to 2020
The dataset contains data related to registered offshore sediment disposal sites around the UK coast and includes volumes of disposed material, dredged areas, calculated levels of contaminants in the disposal material and licence details. Data were collated for the years 2000 to 2020. The Centre for Environment, Fisheries and Aquaculture Science (Cefas) on behalf of Department for environment, food and rural affairs (Defra), report these data for the United Kingdom (England, Scotland, Wales, Northern Ireland),...
Data from: Context-dependent survival, fecundity, and predicted population-level consequences of brucellosis in African buffaloErin E. Gorsich, Vanessa O. Ezenwa, Paul C. Cross, Roy G. Bengis & Anna E. Jolles
1. Chronic infections may have negative impacts on wildlife populations, yet their effects are difficult to detect in the absence of long-term population monitoring. Brucella abortus, the bacteria responsible for bovine brucellosis, causes chronic infections and abortions in wild and domestic ungulates, but its impact on population dynamics is not well understood. 2. We report infection patterns and fitness correlates of bovine brucellosis in African buffalo based on (1) 7 years of cross-sectional disease surveys...
Avian migrants are challenged by seasonal adverse climatic conditions and energetic costs of long-distance flying. Migratory birds may track or switch seasonal climatic niche between the breeding and non-breeding grounds. Satellite tracking enables avian ecologists to investigate seasonal climatic niche and circannual movement patterns of migratory birds. The Double-crested Cormorant (Nannopterum auritum, hereafter cormorant) wintering in the Gulf of Mexico (GOM) migrate to the Northern Great Plains and Great Lakes and is of economic importance...
Data from: Quantifying network resilience: comparison before and after a major perturbation shows strengths and limitations of network metricsChristine Moore, Graeme S. Cumming & John Grewar
1. The resilience literature often assumes that social–ecological reorganization will result in either the removal of deficient system elements (components, interactions) or social learning. Major perturbations are expected to lead to either adaptation or, if accompanied by a regime shift, transformation. This has led to a conflation of the concepts of resilience and adaptation, which has in turn made it difficult to quantitatively distinguish between cases in which a system returned to a previous state,...
Data from: Bayesian inference reveals positive but subtle effects of experimental fishery closures on marine predator demographicsRichard B. Sherley, Barbara J. Barham, Peter J. Barham, Kate J. Campbell, Robert J.M. Crawford, Jennifer Grigg, Catharine Horswill, Alistair McInnes, Taryn L. Morris, Lorien Pichegru, Antje Steinfurth, Florian Weller, Henning Winker, Stephen C. Votier & Cat Horswill
Global forage-fish landings are increasing, with potentially grave consequences for marine ecosystems. Predators of forage fish may be influenced by this harvest, but the nature of these effects is contentious. Experimental fishery manipulations offer the best solution to quantify population-level impacts, but are rare. We used Bayesian inference to examine changes in chick survival, body condition and population growth rate of endangered African penguins Spheniscus demersus in response to eight years of alternating time-area closures...
The population genetic structure of free-ranging species is expected to reflect landscape-level effects. Quantifying the role of these factors and their relative contribution often has important implications for wildlife management. The population genetics of the European badger (Meles meles) have received considerable attention, not least because the species acts as a potential wildlife reservoir for bovine tuberculosis (bTB) in Britain and Ireland. Herein, we detail the most comprehensive population and landscape genetic study of the...
Marine no-take zones can have positive impacts for target species and are increasingly important management tools. However, whether they indirectly benefit higher order predators remains unclear. The endangered African penguin (Spheniscus demersus) depends on commercially exploited forage fish. We examined how chick survival responded to an experimental 3-year fishery closure around Robben Island, South Africa, controlling for variation in prey biomass and fishery catches. Chick survival increased by 18% when the closure was initiated, which...
Hemileia vastatrix is the most important fungal pathogen affecting Coffea arabica and has invaded nearly every coffee-growing region in the world and the causal agent of recurrent disease epidemics. The development of resistant varieties of coffee against H. vastatrix requires fundamental understanding of the biology of the fungus. However, the complete life cycle of H. vastatrix remains unknown and conflicting studies exist as to whether the fungus is capable of sexual reproduction or not. Here...
Background: Rabies is a serious yet neglected public health threat in resource-limited communities in Africa, where the virus is maintained in populations of owned, free-roaming domestic dogs. Rabies elimination can be achieved through the mass vaccination of dogs, but maintaining the critical threshold of vaccination coverage for herd immunity in these populations is hampered by their rapid turnover. Knowledge of the population dynamics of free-roaming dog populations can inform effective planning and implementation of mass...
The causative bacterium of Lyme disease, Borrelia burgdorferi, expanded from an undetected human pathogen into the etiologic agent of the most common vector-borne disease in the United States over the last several decades. Systematic field collections of the tick vector reveal increases in the geographic range and population size of B. burgdorferi that coincided with increases in human Lyme disease incidence across New York State. Here we investigate the impact of environmental features on the...
