Abstract

Austrominius modestus, formerly Elminius modestus, is a relatively small species of four-plated acorn barnacle, which is native to the subtropical and temperate zones of Australasia. It was introduced into Europe in the 1940s, where its current range includes England, Scotland, Wales, Ireland and continental Europe from Denmark to southern Portugal, as well as two reported locations in the Mediterranean Sea. This species occurs intertidally and subtidally on a very wide range of substrata in both its native and introduced range and is found on sheltered to intermediate exposed shores, but is absent from wave-exposed shores, probably due to the relative fragility of its shell. A. modestus is known to be both euryhaline and eurythermal, but its physiology (and that of other cirripedes) has been relatively little studied in comparison with other invertebrate species. Cold temperatures and competition from arctic-boreal barnacle species currently control its northern limit. At the southern limit, desiccation stress, or some other stress(es), may be limiting the abundance of Austrominius modestus by affecting cyprids and/or metamorphs at the settlement and recruitment stages. Abundance may also be limited by factors occurring at the reproductive stage. Since Austrominius modestus is an obligatory cross-fertiliser, the need for a critical breeding density is one of the factors that appears to have slowed the speed of its spread in Europe. Although this species can commence reproducing at a very young age and under optimal conditions produces multiple broods per year, its fecundity has not yet been studied. An examination of the age of first brooding, the timing and size and number of broods per year at sites at the northern (Scotland) and southern (Portugal) limits of the current invasive range of Austrominius modestus may provide a better understanding of the factors controlling its geographic distribution, abundance and speed of spread in its non-native range. For instance, warming waters could result in increased reproduction and recruitment of Austrominius modestus, leading to a reduced density of the native Semibalanus balanoides Linnaeus which may drive Semibalanus balanoides to extinction in certain parts of its range. Further research is necessary to determine the functional role of Austrominius modestus in relation to native species in order to understand the implications that changes in abundance and distribution of A. modestus may have for ecosystems.

Abstract

Marine fouling affects most man-made surfaces temporarily or permanently immersed in the sea, causing important economic costs. Intense research is aimed at methods for preventing or reducing fouling development. The most widespread solution to inhibit fouling is to make surfaces unsuitable for settlers by coating them with antifouling paints containing toxic compounds. Most such antifouling agents give undesirable effects on nontarget species, including commercially important ones. The search for new nontoxic antifouling technologies has become a necessity, particularly after the ban of organotin compounds such as tributyltin (TBT), once the most widespread and used antifouling agent. Alternative organic and metal-based biocides are now used in antifouling paints, but their possible toxic effects on the aquatic environment are not yet fully understood. A nontoxic alternative for antifouling protection comes from the possibility of adopting natural antifouling compounds that are and may be found in marine sessile invertebrates like sponges, bryozoans, corals, and tunicates and in marine microorganisms. Such metabolites can prevent their producers from being fouled on by other organisms or be responsible for specific metabolic functions that may interfere with biofouling species adhesion. As natural marine compounds, they may inhibit settlement through a nontoxic mechanism without adverse effects to the environment. Such compounds could be developed into active ingredients of new antifouling coatings. So far, a rather limited number of natural products antifoulants (NPAs) has been isolated from marine organisms, but a huge reservoir of compounds with potential antifouling activity is hidden in marine organisms. The Special Issue on Marine Natural Products with Antifouling Activity aims at the discovery of such compounds their activity, toxicity and potential application in environmentally friendly antifouling coatings.

Abstract

A groundbreaking and accessible field guide to the birds of Britain and IrelandThis guide is a celebration of the beauty of birds and the British and Irish countryside. Aimed at beginner and intermediate birders, yet suitable for all levels, this new volume in the groundbreaking Crossley ID Guide series is the most user-friendly guide to the birds of Britain and Ireland. Following The Crossley ID Guides' award-winning design, this book looks at all regularly occurring species in Britain and Ireland, and shows readers how to identify birds in their natural habitats using size, structure, shape, probability, and behavior—just like the experts do! Stunning images are accompanied by the colorful and compelling text of Dominic Couzens, one of Britain's leading nature writers.This unique book treats more than 300 species—all the regularly occurring birds likely to be encountered by observers--and the guide's attractive pages provide a real-life approach to bird identification. Beautiful, in-focus scenes present birds in various plumages and in lifelike poses set in identifiable British and Irish habitats. The plates also illustrate how a bird's appearance changes with distance. Organizing images in cohesive, easy-to-understand plates rather than as separate photographs, this book also sets itself apart by containing more images that demonstrate flight, behavior, habitat, and plumages than any other volume available. Not only is this field guide a reference book, it is also a spectacular teaching resource that makes it easy for nature enthusiasts to see and appreciate the big picture of bird identification.The most user-friendly guide to the birds of Britain and IrelandA close look at more than 300 regularly occurring speciesAward-winning Crossley ID Guide designLifelike images of birds from near to farA celebration of the British and Irish countrysideA teaching and field guide and essential referenceConcise and compelling text by Dominic Couzens and Richard Crossley

Abstract

A richly illustrated natural history of the world's crabs that examines their diversity, ecology, anatomy, behavior, and moreThis lavishly illustrated book offers a remarkable look at the world’s crabs. More than 7,000 crab species, in 100 different families, are known today. Their unique physiology and complex behaviors have made them one of the most diverse and adaptable of all animal groups. They can thrive in the darkness of abyssal seas, on the edges of scalding hot volcanic hydrothermal vents, on sunlit coral reefs, on wave-washed rocky shores, and in tropical rainforests at the tops of mountains. They even persist in some of the harshest desert conditions. Playing a vital role in marine and coastal ecology, crabs have been identified as keystone species in habitats such as coral reefs and coastal tropical swamps.Crabs comprises five chapters: evolutionary pathways; anatomy and physiology; ecology; reproduction, cognition, and behavior; and exploitation and conservation. Individual chapters include a variety of subtopics, each illustrated by exceptional images, and followed by numerous double full-page species’ profiles. Each profile has been chosen to emphasize remarkable and intriguing aspects of the life of these fascinating creatures—some species may be familiar, but many are beyond anything you have seen before and will stretch your understanding of what it is to be a crab.Written by a world authority, Crabs offers an accessible overview of these fascinating crustaceans.More than 190 spectacular color photographsAccessible and well-organized chaptersFull profiles on 42 iconic species from across the world
