Forms of phosphorus in an oxisol under different soil tillage systems and cover plants in rotation with maize

Revista Brasileira de Ciência do Solo, 2014
Phosphorus fractions play a key role in sustaining the productivity of acid-savanna Oxisols and are influenced by tillage practices. The aim of this study was to quantify different P forms in an Oxisol (Latossolo Vermelho-Amarelo) from the central ...

Nitrogen and Phosphorus Allocation Strategies in a Chronosequence of Tropical Dry Forests: Plant Coordination and Environmental Drivers

Biotropica, Volume 57, Issue 2, March 2025.
We explored the allocation strategies of N and P in leaves and fine roots (metabolic organs) and, in stems and coarse roots (woody organs) of nine dominant tree species in secondary tropical dry forests using scaling analysis. The scaling relationships of P versus N concentrations in non‐leaf organs were isometric across secondary succession and ...

Testing the contribution of vertebrate predators and leaf traits to mainland–island differences in insect herbivory on oaks

Journal of Ecology, Volume 113, Issue 1, Page 140-154, January 2025.
The authors explored how insularity influences herbivory in oaks across island–mainland sites. By experimentally excluding vertebrate predators (e.g. birds, bats) and measuring leaf traits (e.g. phenolics, specific leaf area, nutrients), they provide insights into the mechanisms driving island–mainland herbivory patterns.

Resposta de Brachiaria humidicola cv. Tupi a fertilização fosfatada. [PDF]

, 2011
O efeito de níveis de fósforo (0, 30, 60, 90 e 120 mg de P/dm3) sobre o rendimento de matéria seca (MS) e composição química de Brachiaria humidicola cv. Tupi foi avaliado sob condições de casa-de-vegetação.

Efecto de la concentración de fósforo sobre su asimilación en tres genotipos de frijol común (Phaseolus vulgaris L.)

Agronomía Mesoamericana, 2016
En condiciones controladas de invernadero y cultivo hidropónico en frascos de 1000 cc, aereada con 400 ml.l; de solución.minuto-1, se hicieron crecer plantas de frijol común, en un diseño de bloques completamente al azar; con cuatro repeticiones.

Differential responses of community‐level functional traits to mid‐ and late‐season experimental drought in a temperate grassland

Journal of Ecology, Volume 112, Issue 10, Page 2292-2306, October 2024.
These findings suggest that functional trait composition of grassland communities may shift under climate change‐induced drought, depending on the growing season timings. Trait‐based attempts to predict ecosystem functioning must account for such temporal variation in community trait values.

Tree and mycorrhizal fungal diversity drive intraspecific and intraindividual trait variation in temperate forests: Evidence from a tree diversity experiment

Functional Ecology, Volume 38, Issue 5, Page 1089-1103, May 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The study of tree species coexistence is crucial to understand the assembly of forest communities. In this context, trees adjust their traits in response to the interactions with other trees and, specifically, as a result of the competition for resources.

Application of trophic state indices in the dam of Salto Grande [PDF]

, 2013
Eutrophication is the process by which nutrients, mainly phosphorus, are contributed. Currently, this has increased due to human activity and population growth which has caused the deterioration of water quality and limited its potential uses.
