- The goal of the EcoVeg approach is to fully describe and classify the diversityof the Earth’s terrestrial ecosystems based on vegetation and ecological pro-cesses. The EcoVeg approach was used to develop the International VegetationClassification (IVC) and various national classifications, which integrate pat-terns of vegetation growth form, structure, and floristics with ecological andbiogeographic drivers at multiple spatial scales, from global formations to localplant communities. The approach remains unique among terrestrial ecologicalclassifications in providing types at these scales....AuthorsDon Faber-Langendoen, David A.

- The agricultural and forestry sectors of the Caribbean are increasingly vulnerable to the challenges posed by climate change. Less predictable rainfall, more intense extreme climate events, and more days of extreme heat threaten crop and livestock productivity intensify pest and disease pressures, degrade soil health, and lead to significant social and economic challenges (Méndez-Lazaro et al. 2023; Gould et al. 2018). Although climate scenarios can help assess the detrimental implications of climate change in the Caribbean, substantial gaps persist in public knowledge regarding climate...AuthorsNora Alvarez-Berrios, Viviana Medina-Rodríguez, William A.

- About 40% of the Brazilian Amazon has been deforested or suffered changes in forest structure through degradation (selective logging, fires, and fragmentation). The impact of forest degradation on the forest's sensitivity to climate extremes has not been fully explored because of a lack of data and the complex interplay of forest structure and climate drivers. Here, we combined forest structure data from 545 airborne lidar transects (375 ha each) across the Brazilian Amazon with the Ecosystem Demography Model (ED2). We explore the forest's functional response to near-present (1981–2019)...AuthorsMarcos Longo, Michael Keller, Lara Kueppers, Kevin Bowman, Ovidiu Csillik, António Ferraz, Paul Moorcroft, Jean Pierre Ometto, Britaldo Soares-Filho, Xiangtao Xu, Mauro de Assis, Eric Görgens, Erik Larson, Jessica Needham, Elsa Ordway, Francisca Pereira, Ekena Rangel Pinagé, Luciane Sato, Liang Xu, Sassan SaatchiSourceEnvironmental Research LettersYear2025
- Forest canopy height is a fundamental ecosystem property—influencing patterns of forest carbon storage and forest ecosystem responses to climate variability and change. Previous studies have analyzed environmental drivers influencing spatial variation in canopy height at landscape-to- regional scales; however, far less is known about the environmental determinants underlying regional and global scale variation in forest canopy height. Using the canopy height metrics products from Global Ecosystem Dynamics Investigation (GEDI), a space-borne Light Detection and Ranging (LiDAR) instrument...AuthorsShaoqing Liu, Ovidiu Csillik, Elsa M.

- Tropical forests abound with regional and local endemic species and house at least half of the species on Earth, while covering less than 7% of its land (Lahssini et al., 2022; Bolívar-Santamaría et al., 2021; Bullock et al., 2020; Wilson, 1988; Gentry, 1988; as cited in Skole and Tucker, 1993). Their clearing, burning, draining, and harvesting can make slopes dangerously unstable, degrade water resources, change local climate, or release to the atmosphere as greenhouse gases (GHGs) the organic carbon (C) that they store in their biomass and soils. These forest disturbances accounted for...AuthorsEileen Helmer, N.R. Goodwin, V. Gond, C.M. Souza, G.P. AsnerKeywordsSourceRemote Sensing Handbook, Volume IVYear2025
- In the past three decades, Puerto Rico (PR) experienced five hurricanes that met or exceeded category three, and they caused severe forest structural damage and elevated tree mortality. To improve our mechanistic understanding of hurricane impacts on tropical forests and assess hurricane‐affected forest dynamics in Earth system models, we use in situ forest measurements at the Bisley Experimental Watersheds in Northeast PR to evaluate the Functionally Assembled Terrestrial Ecosystem Simulator coupled with the Energy Exascale Earth System Model Land Model (ELM‐FATES). The observations show...AuthorsMingjie Shi, Michael Keller, Barbara Bomfim, Lara Kueppers, Charlie Koven, Jessica Needham, Tamara Heartsill Scalley, L. Ruby.

- With increasing frequency and severity, coastal cities are facing the effects of extreme weather events, such as sea-level rise, storm surges, hurricanes, and various types of flooding. Recent urban resilience scholarship suggests that responding to the cascading complexities of climate change requires an understanding of cities as social-ecological-technological systems, or SETS. Advances in data visualization, sensors, and analytics are making it possible for urban planners to gain more comprehensive views of cities. Yet, addressing climate complexity requires more than deploying...AuthorsMathieu Feagan, Tischa A. A. Munoz, Robert Hobbins, Kristin Baja, Mikhail Chester, Elizabeth M.

- The wildland-urban interface (WUI) is the area where houses are in or near wildland vegetation and where many environmental problems concentrate. Consistent WUI maps across all U.S. lands and territories are therefore needed for effective environmental management and policy efforts. However, such maps are lacking for Puerto Rico and the U.S. Virgin Islands. Here, we mapped the WUI in Puerto Rico and the U.S. Virgin Islands for 2010 using the same mapping approach as in the conterminous United States and integrating population census, land cover, and land ownership information. We found...AuthorsSebastián Martinuzzi, Olga M. Ramos González, David P. Helmers, Tamara Heartsill Scalley, Volker C. Radeloff, Maya QuiñonesKeywordsYear2025
- La vertiente del pacifico de Nicaragua contiene areas naturales como el bosque seco, esta zona, aunque es un mosaico de ecosistemas y microclimas predominan las reducidas precipitaciones con una marcada epoca seca, yes importante para la diversidad aviar por las especies linicas que contiene. Este contiene mas del 50% de las especies reportadas en Nicaragua, ademas de un relevante numero de investigaciones que se han llevado a cabo historicamente y mas activamente en los ultimos 30 años . Esta zona muestra una mezcla d e aves presentes en otras macroregiones como la vertiente del Caribe...AuthorsMarvin A Tórrez, Wayne J.

- Forest ecosystems absorb and store about 25% of global carbon dioxide emissions annually and are increasingly shaped by human land use and management. Climate change interacts with land use and forest dynamics to influence observed carbon stocks and the strength of the land carbon sink. We show that climate change effects on modeled forest land carbon stocks are strongest in tropical wildlands that have limited human influence. Global forest carbon stocks and carbon sink strength may decline as climate change and anthropogenic influences intensify, with wildland tropical forests, especially...AuthorsJ.
