Seed provision and dryland crops in the semiarid regions of Eastern Kenya: [PDF]

"Over the last two decades, several seed-related programs have been initiated in eastern Kenya to improve farmers' access to quality seeds of dryland cereals and legumes. They are provided during two occasions, regular and emergency times. But very often,

Low-carbon agricultural technologies improve forage and feed production in the Caatinga biome, Brazil: Characteristics, comparison, effects of climate change, resilience, local development, and food security

Scientia Agropecuaria
Adjustments in Brazilian livestock are necessary to minimize greenhouse gas (GHG) emissions, since the largest source of methane comes from ruminants’ enteric fermentation, and of carbon from deforestation.

Plant clonal morphologies and spatial patterns as self-organized responses to resource-limited environments

, 2014
We propose here to interpret and model peculiar plant morphologies (cushions, tussocks) observed in the Andean altiplano as localized structures. Such structures resulting in a patchy, aperiodic aspect of the vegetation cover are hypothesized to self ...

An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, EarlyView.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...

Effect of Different Irrigation Programs on Structural Characteristics, Productivity and Water Use Efficiency of Opuntia and Nopalea Forage Cactus Clones

Grasses
The objective of this study was to evaluate the structural characteristics, yield and water use efficiency of forage cactus under daytime and nighttime irrigation in a Brazilian semiarid region. The experiment followed a completely randomized design in a

Spatial characteristics of thunderstorm rainfall fields and their relation to runoff [PDF]

, 2003
The main aim of this study was to assess the ability of simple geometric measures of thunderstorm rainfall in explaining the runoff response from the watershed. For calculation of storm geometric properties (e.g.

Geographic risks to functional groups of mammals and birds from habitat loss in Mexico

Conservation Biology, EarlyView.
Abstract There is a need to quantify the impact of habitat loss due to anthropogenic factors on different aspects of biodiversity, such as functional trait diversity represented by functional groups (FGs). We developed a metric to assess the weighted risk of loss of habitat for 33 FGs of mammals and 36 FGs of birds in Mexico based on potential ...

Mapping Burned Area in the Caatinga Biome: Employing Deep Learning Techniques

Fire
The semi-arid Caatinga biome is particularly susceptible to fire dynamics. Periodic droughts amplify fire risks, while anthropogenic activities such as agriculture, pasture expansion, and land-clearing significantly contribute to the prevalence of fires.

Scenarios and strategies for future‐proofing ecosystem management under climatic novelty

Conservation Biology, EarlyView.
Abstract Climate change is driving unprecedented declines in dominant, habitat‐forming foundation species across marine and terrestrial ecosystems globally. As climatic novelty becomes the norm, ecosystem reassembly will become increasingly common. Predicting and understanding these transitions, and their implications for future ecosystem functioning ...
