Microbial Odorant Detection Guides Drosophila Parasitoids Seeking Hosts in Fermenting Fruits

open access: yesAdvanced Science, EarlyView.
Yeast microbes in fermenting fruits attract both host flies and their parasitoid wasps. Female Leptopilina boulardi detect yeast‐emitted ethyl esters via two olfactory receptors, LbouOR167 and LbouOR136. A conserved residue, Leu159, is critical for binding these compounds, enabling female wasps to locate host‐rich habitats.

Ban Glyphosate—Does It Affect the Swedish Farmers' Willingness to Grow Cover Crops?

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT The cultivation of cover crops is one of the new Eco‐scheme practices introduced in Sweden. This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban.

Foraging ecology predicts learning performance in insectivorous bats. [PDF]

open access: yesPLoS ONE, 2013
Bats are unusual among mammals in showing great ecological diversity even among closely related species and are thus well suited for studies of adaptation to the ecological background.

Coping With Production Risk: Effects of Sown Plant Diversity on the Attractiveness of Crop Insurance in Grasslands

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Increased frequency of extreme weather events, particularly droughts, threatens grassland farming by destabilizing yields and farms' economic viability. We examine, theoretically and through numerical simulations, how sown plant diversity (natural insurance) influences the attractiveness of indemnity and drought index insurance (formal ...

DNA barcoding reveals seasonal shifts in diet and consumption of deep-sea fishes in wedge-tailed shearwaters.

open access: yesPLoS ONE, 2018
The foraging ecology of pelagic seabirds is difficult to characterize because of their large foraging areas. In the face of this difficulty, DNA metabarcoding may be a useful approach to analyze diet compositions and foraging behaviors.

Litter Surface Temperature: A Driving Factor Affecting Foraging Activity in Dinoponera lucida (Hymenoptera: Formicidae)

open access: yesSociobiology, 2021
Dinoponera lucida is a poneromorph ant endemic to the Atlantic Forest of Brazil. The species is classified as endangered in Brazil’s Red List due to its peculiar reproductive biology and high habitat fragmentation. Herein, we characterize D.

Climate Change Mitigation in the Dairy Sector: Uncovering Heterogeneity Through Eco‐Efficiency Clubs

open access: yesAgribusiness, EarlyView.
ABSTRACT Combining climate change goals with economic targets is crucial for the dairy sector, which is a significant contributor to agricultural greenhouse gas (GHG) emissions worldwide. In this paper, we assess economic and climate change implications of dairy production with panel data of Irish dairy farms from 2013 to 2021.

Suite of simple metrics reveals common movement syndromes across vertebrate taxa [PDF]

open access: yes, 2017
ecause empirical studies of animal movement are most-often site- and species-specific, we lack understanding of the level of consistency in movement patterns across diverse taxa, as well as a framework for quantitatively classifying movement patterns. We
