Book Description
Parrotfish are found on almost every coral reef in the world. This ubiquity and uniqueness of their feeding action make them one of the most important groups of fishes within coral reef ecosystems. But why, exactly, are parrotfish so important to reefs? Can the evolution of a particular jaw morphology and feeding action really have had such a large impact on the health and functioning of the world's coral reefs? This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.

Book Description
Coral reef ecosystems are declining globally, and anthropogenic influences have caused a shift from coral dominated reefs to algal dominated reefs. Reef grazers, like parrotfish, feed on algae growing in and on corals and prevent algal domination. In the US Caribbean, Stoplight Parrotfish (Sparisoma viride) is the most landed parrotfish species and has experienced dramatic increases in fishing pressures in recent years; however, recent stock assessments have been unsuccessful, citing a lack of basic life history information. This study addressed these data gaps, using a combination of fisheries-dependent and -independent samples to compare age, growth, and reproductive biology of Stoplight Parrotfish in Puerto Rico (PR), St Thomas (STT), and St Croix (STX). In all three islands, Stoplight Parrotfish showed year-round spawning seasonality with the potential for daily spawning. A small proportion of males appear to utilize an alternative mating strategy to avoid competition with haremic males, and some large females may maximize reproductive success by not undergoing sexual transition. Size and age structure differed significantly between the three islands, with more small fish in PR compared to STT and STX, and a smaller range of ages in STT. Fish from STT also grew more quickly and reached sexual maturity at a larger size than fish from PR and STX. Differences between the sampling locations may reflect differences in the gear and practices of the fisheries of the islands themselves, which supports the notion of island-specific management and regulations. The results of this study can be used for more successful stock assessments, and for creation of fishing regulations to protect these vital reef grazers.

Book Description
Reefs provide a wealth of opportunity for learning about biological and ecosystem processes, and reef biology courses are among the most popular in marine biology and zoology departments the world over. Walter M. Goldberg has taught one such course for years, and he marshals that experience in the pages of The Biology of Reefs and Reef Organisms. Goldberg examines the nature not only of coral reefs—the best known among types of reefs—but also of sponge reefs, worm reefs, and oyster reefs, explaining the factors that influence their growth, distribution, and structure. A central focus of the book is reef construction, and Goldberg details the plants and animals that form the scaffold of the reef system and allow for the attachment and growth of other organisms, including those that function as bafflers, binders, and cementing agents. He also tours readers through reef ecology, paleontology, and biogeography, all of which serve as background for the problems reefs face today and the challenge of their conservation. Visually impressive, profusely illustrated, and easy to read, The Biology of Reefs and Reef Organisms offers a fascinating introduction to reef science and will appeal to students and instructors of marine biology, comparative zoology, and oceanography.

Book Description
Parrotfishes are caught primarily by fish traps and spearfishing (targeted and incidental) for personal and commercial consumption. Over half (65 percent) of the responding countries and overseas territories indicated that they have either a complete harvesting ban or fishing regulations in place to promote the protection of parrotfishes to some extent. About half (56 percent) of the responding countries have fishery-independent surveys for parrotfishes, but the metrics evaluated by these surveys are not the same. Similarly, parrotfish-related outreach and education was varied throughout the Caribbean. Twelve countries (32 percent) report having specific parrotfish outreach campaigns or materials, while in other countries campaigns and materials were geared towards marine conservation in general. Most countries agree that long-term protection for parrotfishes is critical, but consensus about the specific measures required to achieve this is lacking.

Book Description
Policy makers and resource managers must make decisions that affect the resilience and sustainability of natural resources, including biodiversity and ecosystem services. However, these decisions are often based on evidence or theory derived from highly altered systems and over short time periods of low-magnitude environmental and climatic change. Because natural systems change and evolve across multiple timescales from instantaneous to millennial, long-term understanding of how past life has responded to perturbations can inform resource managers. By using these natural laboratories of the past, conservation paleobiology and paleoecology provide the framework necessary to anticipate and plan for future changes. The goal of this Research Topic is to heighten awareness among conservation and restoration practitioners to the value and applications of long-term perspectives provided by conservation paleobiology and paleoecology. Most conservation studies focus on systems already impacted by anthropogenic change; these studies would benefit from paleontological data through expanded temporal scales, identification of baselines, and an understanding of how organisms have responded to past changes. However, resource management decisions rarely include input from paleontologists, and paleoecological research is rarely incorporated into conservation decision-making. We seek to bridge this research-implementation gap by highlighting the application of paleoecological data to issues such as biodiversity dynamics, extinction risks, and resilience to perturbations, among other topics. We hope to foster new cross-disciplinary synergies by encouraging conservation scientists and managers to collaborate with paleontologists to improve conservation decision-making and by increasing awareness among paleontologists to the needs of the resource management community. This Research Topic will provide a forum for both the paleontological and resource management communities to exchange ideas that will enhance restoration and conservation decision-making. We invite papers on conceptual advances, reviews of specific topics to guide efforts in research or practice, case studies of successful applications, articles describing datasets with applied value, and perspective papers summarizing a body of paleontological research with relevance to the resource management community. Topics can include but are not limited to: • Responses of species, communities, and ecosystems to perturbations • Strategies to achieve the direct integration of paleobiology and paleoecology into on-ground resource management • Identifying baselines and reference conditions • Increasing the robustness of forecasting models through the incorporation of paleontological data • Identifying key species, interactions, and other phenomena as indicators of impending change • New methodologies, analytical tools, and/or proxies in the application of paleontological data to conservation and restoration practice Lynn Wingard, Damien Fordham, and Greg Dietl have no conflicts of interest. Chris Schneider has a potential conflict of interest where manuscripts pertain to stakeholders in the petroleum industry, as she is an independent contractor in the Alberta Oil Sands mining area.

Book Description
A Publishers Weekly Best Book One of the New York Public Library's "25 Books to Remember" for 1999 Lavishly illustrated and meticulously researched, filled with fascinating facts and astonishing descriptions of animal behavior, Bruce Bagemihl's Biological Exuberance is a landmark book that will change forever how we look at nature. Homosexuality in its myriad forms has been scientifically documented in more than 450 species of mammals, birds, reptiles, insects, and other animals worldwide. Biological Exuberance is the first comprehensive account of the subject, bringing together accurate, accessible, and nonsensationalized information. Drawing upon a rich body of zoological research spanning more than two centuries, Bagemihl shows that animals engage in all types of nonreproductive sexual behavior. Sexual and gender expression in the animal world displays exuberant variety, including same-sex courtship, pair-bonding, sex, and co-parenting—even instances of lifelong homosexual bonding in species that do not have lifelong heterosexual bonding. Part 1, "A Polysexual, Polygendered World," begins with a survey of homosexuality, transgender, and nonreproductive heterosexuality in animals and then delves into the broader implications of these findings, including a valuable perspective on human diversity. Bagemihl also examines the hidden assumptions behind the way biologists look at natural systems and suggests a fresh perspective based on the synthesis of contemporary scientific insights with traditional knowledge from indigenous cultures. Part 2, "A Wondrous Bestiary," profiles more than 190 species in which scientific observers have noted homosexual or transgender behavior. Each profile is a verbal and visual "snapshot" of one or more closely related bird or mammal species, containing all the documentation required to support the author's often controversial conclusions.
