Assessing Climate Change Impacts on Runoff Variability and Extremes in China Using High‐Resolution Simulations

International Journal of Climatology, EarlyView.
Future runoff in China shows strong regional and seasonal disparities, with the Southeast basin seeing the largest increase in annual runoff. Wetter summers and drier winters are expected in the south, whilst the northwest will face the opposite. Over 56% of regions are expected to experience more extreme high runoff, and over 40% face intensified low ...

Potential Use of Herbicide Seed Safener and Pre-Emergent Residual Herbicides When Establishing Tropical Perennial Grasses—A Preliminary Study

Seeds
Annual grass weeds can provide significant competition to an establishing sown tropical perennial grass pasture. At least two years of grass weed control prior to sowing is required to reduce the weed seed bank.

Fumigant toxicity and repellency of citronella grass essential oil (Cymbopogon nardus (L.) Rendle) to German cockroaches (Blattella germanica L.)

European Journal of Biological Research, 2021
Citronella grass (Cymbopogon nardus (L.) Rendle) is a tropical plant that can develop as an insect pest fumigant and repellent, especially for the control of the populations of German cockroaches (Blattella germanica L.). The research aims to investigate

Características fermentativas e químicas de silagens de capim-marandu produzidas com quatro pressões de compactação Fermentative and chemical characteristics of marandugrass silage submitted to four compaction pressures

Revista Brasileira de Zootecnia, 2007
Objetivou-se estudar silagens de capim-marandu (Brachiaria brizantha) produzidas com quatro pressões de compactação (100, 120, 140 e 160 kg MS.m-3) durante a ensilagem. A forrageira foi colhida com 60 dias de crescimento vegetativo (32% de MS).

Dry–Hot Compound Events Driving the 2024 Pantanal Wildfires

International Journal of Climatology, EarlyView.
Extreme wildfires in the Pantanal in 2024 were driven by a cascade of heatwaves, rainfall deficits and the absence of the annual flood pulse. These conditions dried soils and rivers, enhanced fuel accumulation and enabled early and intense fire outbreaks.

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and
