Download or read book Ecological Consequences of Artificial Night Lighting written by Catherine Rich and published by Island Press. This book was released on 2013-04-16 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: While certain ecological problems associated with artificial night lighting are widely known-for instance, the disorientation of sea turtle hatchlings by beachfront lighting-the vast range of influences on all types of animals and plants is only beginning to be recognized. From nest choice and breeding success of birds to behavioral and physiological changes in salamanders, many organisms are seriously affected by human alterations in natural patterns of light and dark. Ecological Consequences of Artificial Night Lighting is the first book to consider the environmental effects of the intentional illumination of the night. It brings together leading scientists from around the world to review the state of knowledge on the subject and to describe specific effects that have been observed across a full range of taxonomic groups, including mammals, birds, reptiles and amphibians, fishes, invertebrates, and plants. Ecological Consequences of Artificial Night Lighting provides a scientific basis to begin addressing the challenge of conserving the nighttime environment. It cogently demonstrates the vital importance of this until-now neglected topic and is an essential new work for conservation planners, researchers, and anyone concerned with human impacts on the natural world.

Download or read book Environmental Effects Monitoring for Exploration Drilling written by Robert A. Buchanan and published by [Calgary] : Environmental Studies Research Funds. This book was released on 2004 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main goal of this study was to develop a strategy for monitoring environmental effects at a single exploratory offshore well on the east coast. Work carried out in the study consisted of consultations with scientists, regulators, & stakeholders; reviews of regulatory regimes; toxicity results relevant to exploratory activities; and development of a decision tree for determining when & how to conduct environmental effects monitoring (EEM). The study report first presents background on potential issues related to the environmental impacts of exploratory drilling, the characteristics of typical exploratory drill rigs & drilling muds, the regulatory regime in Canada & elsewhere, and the biological & other effects of drilling. It then summarizes EEM programs & their results for exploratory wells on the Scotian Shelf & Grand Banks; outlines EEM issues of concern for the Newfoundland & Nova Scotia offshore, and discusses issue similarities & differences between the two areas; and draws brief conclusions on the application of production EEM experience to exploratory drilling EEM. Finally, an EEM decision process based on three scenarios appropriate to the east coast is presented, along with recommended study designs to address the scenarios.

Book excerpt: Originally published in 1986, this book is concerned with the ways in which seabirds function as predators in the marine environment; in particular about how they find and catch food and how much of it they consume. It reviews both the feeding ecology of seabirds (including adaptations for flight and diving) and also most of the leading field studies (in polar, temperate and tropical regions) that have quantitatively examined the interactions of seabird communities with their prey.

Download or read book Volume 1 Seabird Biodiversity and Human Activities written by Jaime A. Ramos and published by CRC Press. This book was released on 2022-06-30 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seabirds are global travellers connecting oceans and seas all over the world, and facing multiple threats at local and global scales. Seabirds are long-lived top predators, reflecting changes at lower trophic levels, and are good models to assess ecological changes produced by human societies. Thus, world-wide collaborations are needed to understand seabird ecology and to develop effective conservation measures benefitting both humans and seabird populations. This book provides a modern overview on seabird biodiversity studies: it begins by covering the most up-to-date techniques to study seabirds, and then focus on pragmatic issues related with interactions between seabirds and humans, the use of seabirds as ecological indicators and conservation of seabirds. It gives an updated insight on all these topics and highlights gaps that need further development for a comprehensive understanding of the relationships between seabirds and human actions. This book covers the response of the seabird research community to a biodiversity crisis aiming to contribute towards environmental sustainability. It should provide inspiration to a wide range of professionals and students, including the much needed world-wide collaboration between research groups and practitioners. In this way seabird research and conservation provide an inspiration for the solution of global issues such as climate change.

Book excerpt: This estimate of birds at risk was restricted to these two species as they are the most abundant in the area in the winter (Wilhelm et al., 2007), and have the highest risk of oiling (Wiese and Ryan 2003). [...] PIROP, originally a partnership between the CWS and the University of Moncton, was active from 1965 to 1992, but the bulk of the data was collected during the 1970s and early 1980s (Lock et al. [...] The Grand Banks are bounded by the cold Labrador Current from the north and the warm Gulf Stream to the south. [...] Its waters are shallow with an average depth of 116 m and a maximum depth of 270 m. Similar to the Grand Banks, the Scotian Shelf is influenced by the Labrador Current and the Gulf Stream and is the southernmost extent for sea ice off eastern North America. [...] Counting flying birds continuously results in an over-estimate of abundance, the magnitude of which is dependent upon the relative speeds and directions of the vessel and birds (Spear et al.

Book excerpt: Two marine ornithologists spent two days watching seabird behaviour from a fixed platform at the periphery of offshore wind farm Luchterduinen, The Netherlands, in January 2018. The aim of this study was to assess whether meaningful observations could be made from a non-moving platform, that was part of the wind farm scenery, i.e., one of the turbine foundations. On each observation day, a turbine was selected that was located at the wind farm perimeter, that offered views both of the interior of the wind farm and to waters just outside the wind farm. Earlier studies of seabirds in offshore wind farms have shown that many species tend to avoid wind farms, but also that some individuals, of most species, do enter. However, as these studies are typically conducted from moving platforms (ships or aircraft), it is not known how birds behave within a wind farm perimeter. Birds that find themselves between moving turbines might be intimidated. This might impair their normal feeding behaviour at sea, if the birds would be overly watchful, or mainly seeking to exit the wind farm. On the other hand, birds may specifically move into a wind farm, if they can deal with the fact that turbines are present, and if feeding conditions within the wind farm are good. Such birds would be expected to show feeding behaviour, such as diving.Seabirds may also be habituating to the presence of wind farms in their environment. In the airspace below the rotors, at the sea’s surface and under water, there is no danger to seabirds from collision. Seabirds can thus safely enter and feed in offshore wind farms, and may, over the years, have learnt to exploit this new habitat. Therefore, even though earlier studies have shown displacement of seabirds away from offshore wind farms, this may no longer be the status quo as seabirds may be adapting to the new situation: a marine environment with offshore wind farms.Two auk species, the common guillemot and the razorbill, were seen to move through the wind farm. Birds were seen here both flying and swimming, and diving (presumably for food) was commonly seen. Northern gannets were also commonly seen within wind farm perimeters, but only flying: not swimming or diving. We observed bird behaviour during only two days, in a relatively new wind farm not visited by us earlier, while using different methods of observing seabirds, as compared to earlier T-0 and T-1 studies nearby offshore wind farms. Acknowledging these methodological limitations, seabird presence in the wind farm seemed considerably higher than observed during the earlier T-0 and T-1 (personal observations) periods. This might suggest that these birds (both auks and gannets) are habituating to the wind farms in their environment.Based on this pilot study of only two days of observations in only one season, it is fair to conclude that meaningful behavioural observations can be made from the turbine foundations and that the suggested process of habituation can be followed. It is suggested to conduct more such observations and to do so both from peripheral turbines and from turbines deeper into the wind farm.
Download or read book Identification of Seabirds of the Southern Ocean written by Derek J. Onley and published by Convention. This book was released on 1999 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there has been a sharp decline in the populations of several seabird species, particularly albatrosses. The decline has been widely attributed to fishing with longlines. Seabirds feed on longline baits, get hooked, and drown. This book has been written to help scientific observers identify those seabirds likely to be caught in the Southern Ocean, and takes into account the requirements of the CCAMLR Scheme of International Scientific Observation. It covers the identification of 36 species of birds from the Southern Ocean that have been caught in fishing gear or have been seen feeding from fishing boats. By carefully following the keys to identification, observers should be able to identify most seabirds caught in commercial fisheries in the Southern Ocean with confidence
