Shared soundscapes: The (re)activation of an institutional and individual archive of Peruvian music and dance

open access: yesThe Journal of Latin American and Caribbean Anthropology, Volume 28, Issue 3, Page 206-218, September 2023., 2023
Abstract “Shared soundscapes” is a key concept that allows us to identify the multiplicity of agencies involved in historical sound recordings and their reactivation today. We use the notion to compare two very different Peruvian case studies concerning Asháninka and Nomatsiguenga peoples of the Central Rainforest and Muchik, Quechua, and mestizo ...

Removing invasive giant reed reshapes desert riparian butterfly and bird communities

open access: yesThe Journal of Wildlife Management, Volume 87, Issue 4, May 2023., 2023
Giant reed is a prevalent invasive plant in desert riparian ecosystems that threatens wildlife habitat. From 2008 to 2018, under a United States–Mexico partnership, prescribed fire and herbicide applications were used to remove giant reed and promote native revegetation along the Rio Grande–Bravo floodplain in west Texas and Mexico.

Mechanical Behavior and High Formability of Palm Leaf Materials

open access: yesAdvanced Energy and Sustainability Research, Volume 2, Issue 4, April 2021., 2021
The remarkable formability and mechanical deformation response of leaf sheath sourced from the areca palm tree are demonstrated. The high formability makes it feasible to produce a range of product shapes from the leaf material by single‐step forming processes, with very low embodied energy.

Modeling maize and soybean responses to climatic change and soil degradation in a region of South America

open access: yesAgronomy Journal, Volume 113, Issue 2, Page 1381-1393, March/April 2021., 2021
Abstract Climatic change effects on crop yields are expected to be crop‐ and site specific. Here, Decision Support System for Agrotechnology Transfer models were used to evaluate climatic change effects and mitigation strategies on maize (Zea mays L.) and soybean [Glycine max (L.) Merr.] yields in soils of the subtropical and semi‐arid region of Chaco.

Infection with Batrachochytrium dendrobatidis is common in tropical lowland habitats: Implications for amphibian conservation

open access: yesEcology and Evolution, Volume 9, Issue 8, Page 4917-4930, April 2019., 2019
We conducted a survey testing for the fungal pathogen Batrachochytrium dendrobatidis (Bd) in four lowland sites in Costa Rica to identify local host‐pathogen dynamics and to describe the abiotic environment for this pathogen. We found evidence that lowland study sites exhibit enzootic dynamics with low infection intensity and moderate to high ...

Tropical forest temperature thresholds for gross primary productivity

open access: yesEcosphere, Volume 9, Issue 7, July 2018., 2018
Abstract Tropical forests are hyper‐diverse and perform critical functions that regulate global climate, yet they are also threatened by rising temperatures. Canopy temperatures depart considerably from air temperatures, sometimes by as much as air temperatures are projected to increase by the end of this century; however, canopy temperatures are ...

Quantification and identification of lightning damage in tropical forests

open access: yesEcology and Evolution, Volume 7, Issue 14, Page 5111-5122, July 2017., 2017
The frequency and distribution of lightning‐caused tree death remain unknown for most forests. We developed a combined electronic sensor/camera‐based system for the location and characterization of lightning strikes to the forest canopy at the landscape scale in near real time.

Effect of initial soil properties on six‐year growth of 15 tree species in tropical restoration plantings

open access: yesEcology and Evolution, Volume 6, Issue 24, Page 8686-8694, December 2016., 2016
After six‐year of growth, life history category (pioneer and non‐pioneer tree species) and capacity to fix N2 of the 15 tree species established in restoration plantings was useful to predict their growth rates and response to initial soil properties; also, seed mass was useful to predict growth rates.
