- Tropical forest degradation from logging, fire, and fragmentation not only alters carbon stocks and carbon fluxes, but also impacts physical land-surface properties such as albedo and roughness length. Such impacts are poorly quantified to date due to difficulties in accessing and maintaining observational infrastructures, and the lack of proper modeling tools for capturing the interactions among biophysical properties, ecosystem demography, canopy structure, and biogeochemical cycling in tropical forests. As a first step to address these limitations, we implemented a selective logging...AuthorsMaoyi Huang, Yi Xu, Marcos Longo, Michael Keller, Ryan Knox, Charles Koven, Rosie FisherSourceBiogeosciencesYear2019
Attitudes toward Residential Trees and Awareness of Tree Services and Disservices in a Tropical City
Attitudes toward urban residential trees and awareness of their ecosystem services and disservices may play an important role in management decisions of private residential green spaces with important consequences to urban sustainability. In 2011, 397 household surveys were conducted in six locations of the Río Piedras Watershed (San Juan, Puerto Rico) to evaluate residents’ attitudes toward residential and neighborhood trees and their association with household socio-demographic factors, how awareness of services and disservices relate to the spatial proximity of trees (home versus...AuthorsSofia Olivero-Lora, Elvia Meléndez-Ackerman, Luis Santiago, Raúl Santiago-Bartolomei, Diana García-MontielKeywordsSourceSustainabilityYear2019- Successful attainment of SDG17 is essential for implementing the other 16 SDGs, all of which depend upon secure means of implementation and durable partnerships. Funding for forests from ODA and other sources has trended upwards since 2000, providing reason for cautious optimism. However, REDD+ finance is declining. Private sector investment remains important. The idea of impact investment, which aims to solve pressing environmental and social problems while providing a return for investors, could make a significant contribution to the SDGs. However, not all sustainable development finance...AuthorsDavid Humphreys, Benjamin Singer, Kathleen McGinley, Roy Smith, Budds Jessica, Mónica Gabay, Shonil Bhagwat, Wil de Jong, Helen Newing, Charlotte Cross, Poshendra SatyalKeywordsSourceIn P.

- The temperature response of photosynthesis is one of the key factors determining predicted responses to warming in global vegetation models (GVMs). The response may vary geographically, owing to genetic adaptation to climate, and temporally, as a result of acclimation to changes in ambient temperature. Our goal was to develop a robust quantitative global model representing acclimation and adaptation of photosynthetic temperature responses. We quantified and modelled key mechanisms responsible for photosynthetic temperature acclimation and adaptation using a global dataset of photosyntheti...AuthorsDushan P. Kumarathunge, Belinda E.

- While studies have suggested that climate change adaptation will require dynamic sets of knowledge types—scientific, technical, local, and tacit—about complex, interconnected problems across spatial and temporal scales, less attention has been directed to how these different ways of knowing might be used to transform specific urban knowledge systems that are currently in place, to align with diverse societal needs, and to open new pathways for designing how cities sense, anticipate, adapt to, and learn from extreme weather events. This special issue on knowledge systems for urban resilience...AuthorsMathieu Feagan, Marissa Matsler, Sara Meerow, Tischa A. A. Munoz, Robert Hobbins, Changdeok Gim, Clark A.

- Dust deposition represents an important flux of rock-derived nutrients such as phosphorus to ecosystems on highly weathered soils. Direct measurements of terrestrial dust deposition and its spatial variability are rare, yet they are essential for testing models of dust deposition processes and understanding the biogeochemical effects of dust. Long-term records of precipitation chemistry are available in the Luquillo Mountains of Puerto Rico, which are downwind of the world's largest dust source in Africa. We analyzed 20-year datasets of openfall, throughfall, and wet-only precipitation...AuthorsM.A. McClintock, W.H. McDowell, Grizelle Gonzalez, Michael Schulz, J.C.

- Ecological zonation is a fundamental tool for territorial and ecosystem management. The Holdridge model is a system of ecological zoning based on the identification of bioclimatic units (life zones) that employs the variables of biotemperature, precipitation, potential evapotranspiration (EVP), EVP/P ratio, latitude, and altitude. Argentina displays high environmental variability. However, despite the completion of several comprehensive zonations of intrinsic scientific value, the country lacks an ecological zonation with objectively and precisely delimited units that may be repeated...AuthorsMaría R.
