Abstract

Urban green spaces provide a habitat for a wide variety of bird species. However, changes in characteristics of the surrounding urban morphology could influence the contribution of such green spaces. In particular, bird communities inhabiting small urban parks (SUPs) may be vulnerable, given the high exposure of these spaces to surrounding conditions. In Neotropical cities, the influence of urban-matrix characteristics on bird communities found in SUPs is relatively unknown. In this study, we explored if an increase in surrounding urban matrix variables, such as building densities, average building height, and road coverage around SUPs, negatively influenced the richness and abundance of the bird communities inhabiting them.

Abstract

Mediterranean Chile is part of the five recognized mediterranean‐type climates in the world and harbours a very rich floral diversity. Climate change has been reported as a significant threat to its biodiversity. We used the flora of Mediterranean Chile to analyse how biodiversity patterns, as measured by phylogenetic diversity, genus and species richness will respond to climate change scenarios and identify the areas that will harbour the greatest evolutionary potential and biodiversity richness. We also evaluated how these spatial patterns are depicted within the current network of protected areas.

Abstract

Fluctuations in biodiversity, large and small, pervade the fossil record, yet we do not understand the processes generating them. Here, we extend theory from nonequilibrium statistical physics to describe the fat-tailed form of fluctuations in Phanerozoic marine invertebrate richness. Using this theory, known as superstatistics, we show that heterogeneous rates of origination and extinction between clades and conserved rates within clades account for this fat-tailed form.

Abstract

This article identifies and analyzes some of the main knowledge gaps that affect the development of climate adaptation policies in the Latin American context. It is based on a comparative analysis of online survey results conducted among government officials working on climate adaptation in six countries of the region: Argentina, Brazil, Chile, Costa Rica, Paraguay and Uruguay.

Abstract

The identification of research questions with high relevance for biodiversity conservation is an important step towards designing more effective policies and management actions, and to better allocate funding among alternative conservation options. However, the identification of priority questions may be influenced by regional differences in biodiversity threats and social contexts, and to variations in the perceptions and interests of different stakeholders. Here we describe the results of a prioritization exercise involving six types of stakeholders from the Mediterranean biome, which includes several biodiversity hotspots spread across five regions of the planet (Europe, Africa, North and South America, and Australia).

Abstract

Maintaining biodiversity is crucial for ensuring human well-being. The authors participated in a workshop held in Palenque, Mexico, in August 2018, that brought together 30 mostly early-career scientists working in different disciplines (natural, social and economic sciences) with the aim of identifying research priorities for studying the contributions of biodiversity to people and how these contributions might be impacted by environmental change.

Abstract

Ecotonal zones between eastern semi-arid steppes and Nothofagus spp. forests in western Patagonia are the result of broad ecosystem changes, which have intensified in the last 140 years. Our objectives were to determine historical changes in land use, land cover, and forces driving such changes in Nothofagus ecosystems in the Río Verde district in southern Chile, to support future management recommendations. This interdisciplinary study used historical records including scientific and military expeditions, Landsat imagery, and other archival sources.

Abstract

Subseasonal-to-seasonal (S2S) water quantity and quality forecasts are needed to support decision and policy making in multiple sectors, e.g. hydropower, agriculture, water supply, and flood control. Traditionally, S2S climate forecasts for hydroclimatic variables (e.g. precipitation) have been characterized by low predictability. Since recent next-generation S2S climate forecasts are generated using improved capabilities (e.g. model physics, assimilation techniques, and spatial resolution), they have the potential to enhance hydroclimatic predictions.

Abstract

A tangled web of vicious circles, driven by cultural issues, has prevented ecology from growing strong theoretical roots. Now this hinders development of effective conservation policies. To overcome these barriers in view of urgent societal needs, we propose a global network of postgraduate theoretical training programs.

Abstract

Los Sistemas de Evaluación de Impacto Ambiental son instrumentos de gestión ambiental de carácter preventivo, cuyo principal objetivo es incorporar consideraciones ambientales en los procesos y actividades que acompañan el crecimiento económico de un país. Su influencia en la conservación de la biodiversidad es fundamental, ya que, dentro del proceso de evaluación, permiten identificar y evaluar impactos ambientales potenciales asociados a estas actividades, y definir reparaciones, compensaciones, o mitigaciones. Detener la pérdida de biodiversidad, provocada por actividades humanas y el cambio climático, es un objetivo de carácter mundial.
