... A population of Bridled Quail-Doves (Geotrygon mystacea), a relative of the Ruddy Quail-Dove, decreased significantly and remained low following Hurricanes Irma and Maria on St. Eustatius (Rivera-Milán et al. 2021). Ruddy Quail-Doves tend to feed on the ground, eating fallen fruits, seeds, and occasional insects (Kuecker et al. 2020). With a denser understory and debris on the forest floor, finding food may be more difficult. ...

Island ecosystems are particularly vulnerable to the predicted increases in the intensity and frequency of tropical storms resulting from climate change. In this study, we assess the short-term effects of Hurricane Maria (September 2017) on forest bird communities on the Caribbean island of Dominica. We compared community composition, functional composition, biometrics, and forest structure changes pre-and two years post-hurricane. We caught a total of 408 birds of 18 species across the three years using mist nets. Post-hurricane catch rates were lower than pre-hurricane, and we observed changes in abundance between years across all functional groups, with decreases in the relative abundance of all groups except for omnivores. Hummingbirds showed the greatest reduction in both abundance and richness. Non-metric multidimensional scaling and analysis of dissimilarity indicate a significant shift in community composition for 2018, with 2019 overlapping both 2017 and 2018. The observed changes in richness, abundance, and community composition show that Dominica's forest birds varied in response to Hurricane Maria, and that these changes are still observed two years following the storm. Severe storms like Hurricane Maria disproportionately impact some functional groups, while other species may be able to capitalize on the changes in habitat.
... Species with more specialist requirements include the ruddy quail-dove, which is a forest and woodland species (Kuecker et al., 2020), and the whitefaced quail-dove (Soberanes- González et al., 2020a). Red-billed pigeons, which frequent dry forests in Central America (Stiles & Skutch, 1989;Dunn, 2011). ...
PREFACE El Salvador is regarded as the most environmentally challenged nation in Latin America, despite its location in the highly ecological Meso- American Biodiversity Hotspot. This geophysical, ecological and geopolitical relationship has created serious ecological, economic and sociopolitical cataclysms, and positive conservation actions that are reported in scattered reports and analyses but are rarely included in one book. This book takes a critical look at the environmental system of El Salvador. Environmental disasters (volcanoes, deforestation, hurricanes and mudslides) are currently a hot topic in El Salvador, as the country recovers from a brutal civil war and seeks new developments more strongly related to environmental sustainability. This book adopts a geographical perspective, relying on numerous maps and images throughout the text to illustrate the spatial issues of environmental relations, and models that describe the links between environmental components. A physical and ecological science approach is also used, looking at theoretical, methodological and applied developments in the sciences of physical geography. The book also adopts a historical approach in examining and describing the trajectories of change and the possible human factors behind such changes. While blaming major social upheavals and events (such as the Spanish colonization, the 20th century civil war, and recent intensive land use, rapid urbanization and ineffective environmental management) for the extreme environmental change, the book also argues that recent management efforts and events have seen increased attention to environmental issues in El Salvador, with important ecological recovery in some areas. The book concludes that there are grounds for optimism for the future of El Salvador’s environment, but the possibilities of species re-introductions, reforestation, expanded environmental protection, more critical urban development and better management of natural hazards must be examined critically and socially supported for future benefit.
