- Mas de la mi tad de las reinitas de! Nuevo Mundo (Aves: Parulidae) presentan evidencia de hibridacion intra- e inter-generica. En este trabajo documentamos un individuo de! genero Setophaga, fotografiado en un ecosistema de manglar en la Republica Dominicana el 4 de octubre de 2024. Este individuo muestra caracteristicas morfol6gicas compatibles con un hibrido entre Reinita Amarilla Americana S. aestiva y Reinita Galana S. discolor. Las caracteristicas diagnosticas de! hibrido incluyen una medialuna parcial bajo el ojo y unas estrias gris negruzco en los flancos.AuthorsWayne J.

- Although the Northern Rough-winged Swallow (Stelgidopteryx serripennis) typically winters in Mexico and Central America, recent observations in the Dominican Republic highlight the Caribbean Basin as a potentially important migratory stopover region. We quantified the spatiotemporal patterns of this species in the coastal wetlands of the Samaná Peninsula during mid-January 2019 and mid-March 2023. We recorded maximum flock sizes of approximately 3,000 individuals in January 2019, and 4,000 in March 2023. The January event involved a large westward flight at altitudes of up to 2,000 m,...AuthorsWayne J. Arendt, Marvin A. Tórrez, María M. Paulino, Luis R. Paulino, Danilo A. Mejía, Juan C.

- Knowledge of Nicaragua's Pacific slope seasonal tropical dry forest ecosystem and its avifauna remains limited, hindering effective conservation planning. To assess avian community composition and relative abundance, from 2009 to 2018 we conducted standardized monthly surveys in 147 point counts at 29 study sites along Nicaragua's Pacific slope. We also determined the influence of geographic, climatic, and landscape predictors on avian species richness and community similarity among sites. Overall, we documented 257 species at 29 study sites along the Pacific slope, including 17 species...AuthorsWayne J.

- Human land‐use has dramatically altered the amount, quality and connectivity of habitat for species worldwide. Understanding how these changes affect individual species is essential for predicting the overall consequences of land‐use change for biodiversity.The Caribbean island of Puerto Rico. Forest cover on the island increased from about 18% to 45% from the late 1940's to the early 2000's.Using data on modelled geographic distributions and functional traits for 546 tree species, we evaluated how the gain of modelled potential suitable habitat (i.e., climatically‐suitable and forested)...AuthorsLaura Moro, Pascal Milesi, Eileen Helmer, María Uriarte, Robert MuscarellaKeywordsSourceDiversity and DistributionsYear2026
- Everwet tropical forests, defined by the absence of a pronounced dry season, are globally significant carbon sinks, covering roughly 80% of Southeast Asian tropical forests, 30% of the Amazon basin, and 10% of the Congo Basin. Yet the climatic drivers of stem radial growth in these ecosystems remain understudied. The prevailing hypothesis is that growth is primarily light‐limited, as persistent cloud cover constrains photosynthesis. Evaluating this assumption is critical as climate projections for the humid tropics point towards rising atmospheric evaporative demand, episodic drought, and...AuthorsLaura E. Boeschoten, Chris M.

- Fire is a disturbance that alters nutrient cycling, but its legacy is often reduced to shifts in carbon (C), nitrogen (N), and phosphorus (P). This C:N:P paradigm overlooks the vast suite of other elements critical to decomposer organisms. Post-fire changes in the abiotic environment—especially when interacting with co-occurring stressors such as ultraviolet (UV) radiation—may reorganize the entire multi-element stoichiometric network within litter, yet the direct implications for arthropod decomposer communities remain largely unknown.In a 469-day factorial field experiment in a subtropica...AuthorsWei Huang, Grizelle Gonzalez, Weili Liu, Xiaoming ZouKeywordsSourceFire EcologyYear2026
- The effects of climate warming on phenological patterns and species distributions have been described for many species but understanding how changes in behavior and demography lead to these shifts is less understood. We followed a population of the common frog, Eleutherodactylus coqui, as part of an in-situ field warming experiment (Tropical Responses to Altered Climate Experiment; TRACE), in a humid tropical forest using capture-markrecapture methods. We assessed how growth, body size, and survival varied by warming treatment, sex, and developmental stage of frogs. In warmed plots (+4◦C...AuthorsT.J.Hawley Matlaga, P.A. Burrowes, J.E.

Hurricane Fiona in Puerto Rico: assessing effects and adaptive responses in agriculture and forestry
Hurricanes pose risks for agriculture and forestry in regions where successive storms contribute to cumulative effects that hinder recovery and reduce adaptive capacity. Hurricanes also provide learning opportunities, and successive hurricanes provide opportunity to evaluate whether lessons have been applied and if they reduce the negative effects or improve recovery times. In Puerto Rico, hurricane Fiona made landfall on September 18, 2022, while many communities and landscapes were still facing the longstanding impacts of hurricanes Irma and María, major hurricanes of 2017. This study...AuthorsNora Alvarez-Berrios, Kathleen McGinley, Paloma S. Rodríguez-Serrano, Luis Alexis Rodríguez-Cruz, William A. GouldKeywordsSourceFrontiers in Sustainable Food SystemsYear2026- Biodiversity generally enhances ecosystem productivity, but whether such effects persist or intensify during climate extremes is unclear. Here we synthesized data from 75 biodiversity experiments across grasslands and forests to assess how aridity and soil nutrients modulate plant diversity effects under drought and heat extremes. Biodiversity most strongly enhanced productivity under extreme drought in more arid grasslands but had limited effects in forests under such conditions. More arid grasslands showed enhanced complementarity effects under extreme drought, whereas less arid grassland...AuthorsTakehiro Sasaki, Daniela Hoss, Yuanyuan Huang, Yuki Iwachido, Liting Zheng, Luis Abdala-Roberts, Eric Allan, Harald Auge, Nadia Barsoum, Jürgen Bauhus, Christel Baum, Carl Beierkuhnlein, Friderike Beyer, Pedro Brancalion, Seraina L.

- Methane (CH4) is a potent greenhouse gas, and tropical forests account for roughly one–third of global atmospheric CH4 uptake by soils. Projected warming and more frequent hurricanes in these ecosystems may alter soil CH4 sink strength, as warmer and wetter soils enhance methanogenesis activity. We measured soil CH4 and CO2 efflux during the calendar summer months of 2023 and 2024 alongside continuous records of soil moisture, soil and air temperature, and precipitation in an in–situ warming experiment (TRACE) located in a lowland tropical forest in Puerto Rico, six to seven years after...AuthorsGabriele Larocca Conte, Lucia Zuvela, Rachel Cruz-Pérez, Tatiana Barreto-Vélez, Nibia Becerra-Santillan, Sophia F.
