Heavy Metal and Mineral Composition of Soil, Atmospheric Deposition, and Mosses with Regard to Integrated Pollution Assessment Approach
Abstract The fact that there are no real borders between the biosphere, atmosphere, lithosphere, and hydrosphere means that environmental pollution monitoring studies should not only include one of the environmental spheres. Thus, integrated environmental pollution assessment studies conducted in the biosphere, lithosphere, and atmosphere promote the “whole system” approach. In this study, the aim was to determine the pollution in the atmosphere, soil, and plants by taking advantage of the high pollution accumulation characteristics of the mosses. Prevailing wind has...
Landowners’ Socio-Cultural Valuation of Ecosystem Services Provided by Trees in Costa Rican Agricultural Landscapes
Abstract Over one-fourth of the world’s land area is dedicated to agriculture, and these lands provide important ecosystem services (ES). Trees are a key component of agricultural ecosystems’ ability to provide ES, especially in tropical regions. Agricultural landowners’ evaluation of the ES provided by trees influences management decisions, impacting tree cover at large scales. Using a case study approach, we conducted semi-structured interviews with four types of agricultural landowners in southern Costa Rica to better understand how they value ES provided by...

Factors Associated with Listing Decisions under the U.S. Endangered Species Act
27. Februar 2021
Abstract Conservation efforts, including authorities outlined in the U.S. Endangered Species Act (ESA) of 1973, are attempting to slow the decline of species. Opinions on the success of the ESA vary widely, due in part to few species historically recovering to the point of delisting. Uncertainty surrounding the ESA relates to listing decisions and ambiguity of terminology within the ESA itself. Our goal was to evaluate the relationship, if any, of species characteristics, population metrics, threat level, and potential non-biological indicators to listing decisions under...

Native Riparian Plant Species Dominate the Soil Seedbank of In-channel Geomorphic Features of a Regulated River
13. Februar 2021
Abstract Flow regulation impacts on riparian vegetation composition, often increasing the prevalence of exotic and terrestrial plant species. Environmental flows may benefit native riparian vegetation via the promotion of plant recruitment from riparian soil seedbanks, but this is dependent on an intact native seedbank. Thus, we assessed the composition of the soil seedbank of different riverine geomorphic features to determine its potential response to environmental flows. Soil seedbank samples were taken from channel bars, benches and floodplains at six sites along the...
