Galápagos is one of the most pristine archipelagos in the world and its conservation relies upon research and sensible management. In recent decades both the interest in, and the needs of, the islands have increased, yet the funds and capacity for necessary research have remained limited. It has become, therefore, increasingly important to identify areas of priority research to assist decision-making in Galápagos conservation. This study identified 50 questions considered priorities for future research and management. The exercise involved the collaboration of policy makers, practitioners and researchers from more than 30 different organisations. Initially, 360 people were consulted to generate 781 questions. An established process of preworkshop voting and three rounds to reduce and reword the questions, followed by a two-day workshop, was used to produce the final 50 questions. The most common issues raised by this list of questions were human population growth, climate change and the impact of invasive alien species. These results have already been used by a range of organisations and politicians and are expected to provide the basis for future research on the islands so that its sustainability may be enhanced.

Mangrove forests provide valuable coastal protection from erosion, habitat for terrestrial and marine species, nursery grounds for commercial fisheries and are economically important for tourism. Galapagos’ mangroves usually grow directly on solid lava and fragmented rocky shores, thereby stabilizing the sediment and facilitating colonisation by other plants and many animals. However, until very recently, only inaccurate data described mangrove coverage and its distribution. We mapped mangroves using freely available Google Earth Very High Resolution images based on on-screen classification and compared this method to three semi-automatic classification algorithms. We also analysed mangrove change for the period 2004–2014. We obtained an area of 3657.1 ha of fringing mangrove that covers 35% of the coastline. Eighty percent of mangrove cover is found in Isabela island, and 90% in the western and central south-eastern bioregions. The overall accuracy of mangrove classification was 99.1% with a Kappa coefficient of 0.97 when validated with field data. On-screen digitization was significantly more accurate than other tested methods. From the semi-automated methods, Maximum Likelihood Classification with prior land-sea segmentation yielded the best results. During the 2004–2014 period, mangrove coverage increased 24% mainly by expansion of existing mangroves patches as opposed to generation of new patches. We estimate that mangrove cover and growth are inversely proportional to the geological age of the islands. However, many other factors like nutrients, currents or wave exposure protection might explain this pattern. The precise localization of mangrove cover across the Galapagos islands now enables documenting whether it is changing over time. [ABSTRACT FROM AUTHOR]

Strong and predictable environmental variability can reward flexible behaviors among animals. We used long-term records of activity data that cover several lunar cycles to investigate whether behavior at-sea of swallow-tailed gulls Creagrus furcatus, a nocturnal pelagic seabird, varied with lunar phase in the Galápagos Islands. A Bayesian hierarchical model showed that nighttime at-sea activity of 37 breeding swallow-tailed gulls was clearly associated with changes in moon phase. Proportion of nighttime spent on water was highest during darker periods of the lunar cycle, coinciding with the cycle of the diel vertical migration (DVM) that brings prey to the sea surface at night. Our data show that at-sea behavior of a tropical seabird can vary with environmental changes, including lunar phase. [ABSTRACT FROM AUTHOR]

Geophagy is well known among some Neotropical parrots. The clay apparently adsorbs dietary toxins and/or provides supplemental nutrients. We used location data and 23 environmental layers to develop a predictive model of claylick distribution using Maxent software. We related species characteristics to claylick use and examined how parrot assemblages using claylicks changed with distance from the centre of claylick distribution. Fifty-two parrot claylicks were reported from an area of ca 4 million km
2 but over 50% were restricted to a 35 000 km2 region of southeast Peru and northern Bolivia. Claylicks were strongly associated with moist forest on younger (<65 millions of yr) geological formations and exposed river banks. The predictive model of claylick distribution matched our reported range well, with precipitation of warmest quarter, land cover, temperature seasonality, and distance from the ocean being most important predictors of claylick presence. Twenty-six of the region's 46 parrot species visited claylicks. Species differed greatly in their lick use, but body size, dietary breadth, abundance and other traits were poor predictors of lick use. We are confident that our survey identified the distribution of major parrot claylicks in South America, although less conspicuous parrot geophagy may occur elsewhere. We suggest that claylick distribution reflects both underlying geology (allowing claylick formation in only some regions) and the physiological need for geophagy among parrots in different parts of the continent. Data on the latter are inconclusive, but we argue that parrot claylick distribution supports the contention that geophagy is related more to sodium deficiencies than to protection from dietary toxins.

7. Viable Ecologies : Conservation and Coexistence on the Galápagos Islands

- Ecology--Galapagos Islands
- Abstract
How humans living amid an abundance of diverse flora and fauna help us rethink conservationFamous for their geographic isolation and high proportion of endemic species, the Galápagos Islands have long been promoted as the premier destination for tourists and scientists seeking to escape humanity's impact on the world. This idyllic vision dominates the islands'conservation policy, which, despite calls for a more integrated human-environment approach, continues to emphasize restoration. It ignores the people who call the Galápagos home, who must instead partner with their plant and animal neighbors to secure a thriving future for all. Drawing on years of fieldwork, Paolo Bocci's Viable Ecologies brings attention to the farmers and other marginalized locals who enact their own ways of caring for, and living on, the islands. Through extended observation and experimentation, they craft conservation strategies based on mutual dependence and long-term accountability. They fuse their livelihoods to the ecosystems around them and, in doing so, challenge the image of the Galápagos as a place to be studied and visited but never inhabited. As Bocci argues, the farmers'methods of remediation and recuperation broaden the scope of what conservation can—and should—be.Connecting environmental policy and science to matters of immigration and belonging, Viable Ecologies offers strategies for crafting a future in which humans and nonhumans may thrive.

- Abstract
The terrestrial organisms of the Galápagos Islands live under conditions unlike those anywhere else. At the edge of a uniquely rich mid-ocean upwelling, their world is also free of mammalian predators and competitors, allowing them to live unbothered, exuberant lives. With its giant tortoises, marine iguanas, flightless cormorants, and forests of giant daisies, there's no question that this is a magnificent place. Long before people traversed the Earth, evolution endowed native species with adaptations to these special conditions and to perturbations like El Niño events and periodic droughts. As the islands have grown ever-more connected with humanity, those same adaptations now make its species vulnerable. Today, the islands are best viewed as one big social-ecological system where the ability of each native organism to survive and reproduce is a product of human activity in addition to ecological circumstances. In this book, William H. Durham takes readers on a tour of Galápagos and the organisms that inhabit these isolated volcanic islands. Exuberant Life offers a contemporary synthesis of what we know about the evolution of its curiously wonderful organisms, how they are faring in the tumultuous changing world around them, and how evolution can guide our efforts today for their conservation. The book highlights the ancestry of a dozen specific organisms in these islands, when and how they made it to the Galápagos, as well as how they have changed in the meantime. Durham traces the strengths and weaknesses of each species, arguing that the mismatch between natural challenges of their habitats and the challenges humans have recently added is the main task facing conservation efforts today. Such analysis often provides surprises and suggestions not yet considered, like the potential benefits to joint conservation efforts between tree finches and tree daisies, or ways in which the peculiar evolved behaviors of Nazca and blue-footed boobies can be used to benefit both species today. In each chapter, a social-ecological systems framework is used to highlight links between human impact, including climate change, and species status today, Historically, the Galápagos have played a central role in our understanding of evolution; what these islands now offer to teach us about conservation may well prove indispensable for the future of the planet.

- Abstract
In this innovative volume, the author addresses some important challenges related to the effective and equitable governance of marine protected areas (MPAs). These challenges are explored through a study of 20 MPA case studies from around the world. A novel governance analysis framework is employed to address some key questions: How can top-down and bottom-up approaches to MPA governance be combined? What does this mean, in reality, in different contexts? How can we develop and implement governance approaches that are both effective in achieving conservation objectives and equitable in fairly sharing associated costs and benefits? The author explores the many issues that these questions raise, as well as exploring options for addressing them. A key theme is that MPA governance needs to combine people, state and market approaches, rather than being based on one approach and its related ideals. Building on a critique of the governance analysis framework developed for common-pool resources, the author puts forward a more holistic and less prescriptive framework for deconstructing and analyzing the governance of MPAs. This inter-disciplinary analysis is aimed at supporting the development of MPA governance approaches that build social-ecological resilience through both institutional and biological diversity. It will also make a significant contribution to wider debates on natural resource governance, as it poses some critical questions for contemporary approaches to related research and offers an alternative theoretical and empirical approach.
