Homo sapiens, industrialisation and the environmental mismatch hypothesis

Biological Reviews, EarlyView.
ABSTRACT For the vast majority of the evolutionary history of Homo sapiens, a range of natural environments defined the parameters within which selection shaped human biology. Although human‐induced alterations to the terrestrial biosphere have been evident for over 10,000 years, the pace and scale of change has accelerated dramatically since the onset

Reduced Herbicide Inputs in Cereals

, 1998
End of Project Report The objective of this project was to examine if herbicides used in cereals at rates lower than recommended by the manufacturer (reduced rates) would give acceptable weed control resulting in lower crop production costs. Field trials with a number of herbicides at full and reduced rates were carried out in winter barley, winter ...

Distance of movement in three threatened butterfly species

Ecological Entomology, EarlyView.
Multi‐year mark–recapture analysis using net displacement and Cormack–Jolly–Seber models shows similar daily detectability (0.17–0.22) among species, supporting robust interspecific comparisons. Dispersal kernels differ: lognormal best for Euphydryas aurinia and Parnassius apollo, exponential for Phengaris arion; P.

Modeling the Herbicide-Resistance Evolution in Lolium rigidum (Gaud.) Populations at the Landscape Scale

Agronomy
The repeated application of herbicides has led to the development of herbicide resistance. Models are useful for identifying key processes and understanding the evolution of resistance. This study developed a spatially explicit model at a landscape scale

Outbreak of poisoning by sodium hydrogen methylarsonate (MSMA)—an arsenic‐based herbicide—in horses in Brazil

Equine Veterinary Journal, EarlyView.
Abstract Background Arsenic poisoning in horses is rarely reported in the literature. However, arsenic compounds can be present in rodenticides, pesticides, and herbicides, representing a potential source of accidental exposure for horses. Objective To describe the epidemiological, clinical, and laboratory findings from a herd of 31 horses exposed to ...

Responses of waterhemp and horseweed to cereal rye cover crop termination timing in soybean

Agrosystems, Geosciences & Environment
Field experiments were conducted in soybeans (Glycine max L.) to determine the effects of a cereal rye (Secale cereale L.) cover crop (CC), two CC termination timings (TTs), and four herbicide programs (HP) on the emergence, biomass, and seed production ...

(Not) Covering Climate Risks: A Multimodal News Framing Analysis of Soil Health Reporting in the UK Press

The Geographical Journal, EarlyView.
Short Abstract Risks to soil health from increased flooding and drought due to climate change are a priority risk area for the UK government, but our analysis of two years of UK newspaper coverage on this issue reveals very little attention to it. Our multimodal framing analysis shows that news reports are largely devoid of addressing the root causes ...

Effects of cereal rye residue biomass and preemergence herbicide on the emergence of troublesome southeastern weed species

Frontiers in Agronomy
Cover crops are increasingly adopted to suppress weed growth and reduce reliance on chemical herbicides. A greenhouse experiment was conducted to evaluate the emergence and growth response of troublesome southeastern weeds to various cereal rye (Secale ...
