Management Strategies and Agricultural Calendars for Forage Production in Semi‐Arid Brazil Using AquaCrop

Irrigation and Drainage, EarlyView.
ABSTRACT Forage production in semi‐arid regions of Brazil is limited by water deficit. This study aimed to identify the most adapted and efficient production systems and define their agricultural calendars for the semi‐arid region of Brazil. Twenty‐nine production arrangements that included different cropping conditions, plant density, plant cycles ...

Evaluation of CERES‐Maize Model for Predicting Yield, Evapotranspiration, Water Productivity and Drought Stress Indices Under Center Pivot, Subsurface Drip and Furrow Irrigation Systems With Different Irrigation Levels Simultaneously

Irrigation and Drainage, EarlyView.
ABSTRACT The effects of different irrigation methods (center pivot [CPI], subsurface drip [SDI] and furrow irrigation [FI]) and levels (full irrigation treatment [FIT], 80% FIT, 60% FIT and rainfed) on yield, crop evapotranspiration (ETc), ET‐water productivity (WPET) and drought stress index for leaf expansion (SIE) and photosynthesis (SIP) of maize ...

Artificial Neural Networks for Defining the Operational Parameters of Sand Filters for Irrigation

Irrigation and Drainage, EarlyView.
ABSTRACT The difficulty in defining the working configuration during the operation of sand filters arises from the complexity of the relationships among the variables in the filtration and backwashing processes. The objective was to use artificial neural networks to model the pressure loss and removal efficiency of filtration in a commercial sand ...

Beyond the Metrics: Context‐Aware Calibration for Better Drain Flow Modelling

Irrigation and Drainage, EarlyView.
ABSTRACT Robust hydrological and water quality modelling is essential for advancing the understanding and management of engineered agricultural subsurface drainage systems. Achieving credible model output hinges on calibration strategies that are both rigorous and context sensitive. At the field scale, accurately capturing the dynamics of nutrient load

Urban wild meat and pangolin consumption across southern forested Cameroon: The limited influence of COVID‐19

People and Nature, EarlyView.
Abstract Overexploitation of wildlife is pervasive in many tropical regions, and in addition to being a significant conservation and sustainability concern, it has received global attention given discussions over the origins of zoonotic disease outbreaks.

Likelihood and its use in Parameter Estimation and Model Comparison

Mesure et Évaluation en Éducation, 2015
Parameter estimation and model fitting underlie many statistical procedures. Whether the objective is to examine central tendency or the slope of a regression line, an estimation method must be used.

UCanWBGT: urban street canyon heat stress calculation for weather and climate models

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This work introduces UCanWBGT, a new model to calculate wet‐bulb globe temperature in an urban environment, suitable for use with weather and climate model data. We present the model, then verify its performance against observations made in the streets of Paris during heatwave conditions.

Global determinants of home range sizes in felids: Evidence of human disturbance impact

Journal of Animal Ecology, EarlyView.
This study is the first to demonstrate the influence of anthropogenic factors and species richness in felids on home range size across the entire felid taxon. Felids are a taxon of major interest in conservation biology, and gaining a comprehensive view of their spatial ecology will help derive global conservation recommendations.
