Unbiased approach to diagnose the nutrient status of red guava (Psidium guajava)
Fertilization of guava relies on soil and tissue testing. The interpretation of tissue test is currently conducted by comparing nutrient concentrations or dual ratios with critical values or ranges. The critical value ...
The MUSCLES Treasury Survey I: Motivation and Overview
(IOP Publishing, 2016-04)
Ground- and space-based planet searches employing radial velocity techniques and transit photometry have detected thousands of planet-hosting stars in the Milky Way. With so many planets discovered, the next step toward ...
Microplankton Dynamics Under Heavy Anthropogenic Pressure: the Case of the Bahía Blanca Estuary, Southwestern Atlantic Ocean
Quantifying biotic feedbacks in response to environmental signals is fundamental to assess ecosystem perturbation. We analyzed the joint effects of eutrophication, derived from sewage pollution, and climate at the base of ...
Factors that control the spatial and temporal distributions of phosphorus, nitrogen, and carbon in the sediments of a tropical reservoir
The impacts of anthropic activities have had profound effects on the nitrogen (N) and phosphorus (P) cycles in many aquatic ecosystems. We investigated the spatial and temporal distributions of carbon (C), N, and P in the ...
Estudo de Longa Duração da Distribuição Espaço-Temporal de Nutrientes no Rio do Monjolinho, São Carlos - São Paulo
