Assessment of Mesotrione Leaching Applied Alone and Mixed in Seven Tropical Soils Columns under Laboratory Conditions

Agriculture, 2017
Herbicide leaching is influenced by soil physical and chemical properties as well as the prevailing climatic conditions. However, little is known about leaching of mixture of herbicides in the soil, especially in tropical regions like Brazil.

Compact Tubular Dielectric Elastomer Pump for Indoor Plants

Journal of Applied Polymer Science, EarlyView.
This study develops a mountable rolled dielectric elastomer pump (MRDEP) using silicone films and MWCNT‐based electrodes. The MRDEP is completely soft, silent in operation, and easily mounted on a piping system. We use dry stacking methods, fabricate a multilayer dielectric elastomer actuator (DEA), and a pre‐straining process in one direction before ...

Data on heavy metals content and biochar toxicity in a pristine tropical agricultural soil

Data in Brief, 2018
Accumulation of heavy metals results in soil degradation and impairs the normal functioning of ecosystems. Thus, monitoring of heavy metals is essential in both pristine and polluted soils.

Morphological variation in atlas and axis of Neotropical spiny rats (Rodentia, Echimyidae)

The Anatomical Record, EarlyView.
Abstract The unique morphologies of the first two cervical vertebrae, the atlas and axis, represent a significant innovation in mammalian evolution. These structures support the weight of the head and enable intricate movements of the head and neck.

Listening to tropical forest soils

Ecological Indicators
Acoustic monitoring has proven to be an effective tool for monitoring biotic soundscapes in the marine, terrestrial, and aquatic realms. Recently it has been suggested that it could also be an effective method for monitoring soil soundscapes, but has ...

Geochemistry and microbiology of tropical serpentine soils in the Santa Elena Ophiolite, a landscape-biogeographical approach

Geochemical Transactions, 2022
The Santa Elena Ophiolite is a well-studied ultramafic system in Costa Rica mainly comprised of peridotites. Here, tropical climatic conditions promote active laterite formation processes, but the biogeochemistry of the resulting serpentine soils is ...

Integration of Nutrition and Organic Agriculture Framework in Managing Gastrointestinal Nematodes in Ruminants

Animal Research and One Health, EarlyView.
Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Mapping soils in two watersheds using legacy data and extrapolation for similar surrounding areas

Ciência e Agrotecnologia
Existing soil maps (legacy data) associated with digital mapping techniques are alternatives to obtain information at lower costs, however, tests are required to do it more efficiently. This study had as objectives to compare different methods to extract

Development of a conceptual model of the hydrologic response of tropical Andean micro-catchments in Southern Ecuador [PDF]

, 2012
This paper presents a lumped conceptual model designed for simulating the rainfallrunoff response of mountain micro-catchments with natural vegetation located in the south of Ecuador. The conceptual model is mimicking the soil hydrology and consists of a
