Effects of temperature and browning on the functional response of a freshwater top predator

Journal of Animal Ecology, EarlyView.
This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

US Consumer Appetite for Climate Claims on Beef Products: Does Country‐of‐Origin Matter?

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Beef cattle producers have been receiving pressure to reduce methane emissions from production. Beef products with varying climate claims have recently been introduced to the retail sector, stemming from various countries‐of‐origin. Using data from a US consumer survey, we find a subset of US consumers is willing to pay a premium for Lower ...

Collective Contracts as a Risk‐Sharing Mechanism for Result‐Based Agri‐Environmental Payments: Experimental Evidence

Journal of Agricultural Economics, EarlyView.
ABSTRACT Linking payments from agri‐environment schemes to ecological results or to collective outcomes is viewed as a promising way to increase the effectiveness of agri‐environmental conservation. However, the two approaches are rarely combined.

Landowners' Willingness to Participate in Temporary and Permanent Agri‐Environmental Schemes

Journal of Agricultural Economics, EarlyView.
ABSTRACT Within the EU and beyond, voluntary agri‐environmental and climate schemes (AES) are used to curtail externalities from agricultural production including nitrate leaching, biodiversity degradation and greenhouse gas emissions. This paper investigates and compares Danish landowners' preferences for temporary and permanent AES using a choice ...

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

Insect Science, EarlyView.
Four Drosophilidae species were used to investigate how variation in the host microbiome influences susceptibility to infection. Microbial composition and abundance differed among species and treatments. The effects of microbiome manipulation on host survival were both species‐ and pathogen‐specific.

Overcoming environmental constraints to high‐yielding eastern cottonwood productivity in the southeastern United States

Annals of Applied Biology, EarlyView.
The rising demand for biomass highlights Populus deltoides as a productive woody species. A 6‐year study in Sumter County, SC, assessed the effects of irrigation, fertilization, and clonal variation on growth and productivity. Eight clones were studied under two irrigation levels (33 and 1500 kPa) and nutrient rates (high: up to 182 kg N ha−1; low: 50%

Reintroduction of an Endangered Butterfly, the Mottled Duskywing (Erynnis martialis)

Animal Conservation, EarlyView.
We reintroduced Mottled Duskywing (Erynnis martialis), an endangered skipper butterfly, at different life‐stages to restored oak savanna habitat in Ontario, Canada and then performed intensive post‐release monitoring. Our results show that, at one of three sites, a population was established within two years of initiating releases and that pupae and ...

Buyers' response to third‐party quality certification: Theory and evidence from Ethiopian wheat traders

American Journal of Agricultural Economics, EarlyView.
Abstract When quality attributes of a product are not directly observable, third‐party certification (TPC) enables buyers to distinguish between quality levels and reward sellers accordingly. We study the adoption of TPC by traders in smallholder‐based agricultural value chains in low‐income countries, where traders aggregate products from many small ...

Flow‐controlled expiration improves gas exchange in anaesthetised horses undergoing orthopaedic surgery

Equine Veterinary Journal, EarlyView.
Abstract Background Flow‐controlled expiration (FLEX) has been shown to significantly enhance oxygenation in horses under laboratory conditions. Objective This study aims to corroborate these findings by evaluating the effects of FLEX on gas exchange in a randomised clinical trial involving a large population of clinical horses undergoing orthopaedic ...
