Cities Under Pressure: Evidence on Tourism Growth and Neighbourhood Change in Europe

open access: yesThe Political Quarterly, EarlyView.
Abstract Across European cities, the rapid growth of tourism is reshaping urban life in increasingly contested ways. While the sector continues to support local economies, it is also increasingly associated with the sense that neighbourhoods are becoming less liveable for residents.

Effect of the microbiome on pathogen susceptibility across four Drosophilidae species

open access: yesInsect 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.

Cooling down Lévy flights [PDF]

open access: yesJournal of Physics A: Mathematical and Theoretical, 2007
Let L(t) be a Levy flights process with a stability index α\in(0,2), and U be an external multi-well potential. A jump-diffusion Z satisfying a stochastic differential equation dZ(t)=-U'(Z(t-))dt+σ(t)dL(t) describes an evolution of a Levy particle of an `instant temperature' σ(t) in an external force field.

Ants contribute to raspberry pollination in protected cropping systems

open access: yesAgricultural and Forest Entomology, EarlyView.
Ants visited raspberry flowers more frequently than European honey bees (Apis mellifera), Australian stingless bees (Tetragonula carbonaria) and flies, many transporting raspberry pollen on their bodies, indicating potential pollination capacity. Ants were active flower visitors at most times of the day and may extend the daily pollination window and ...

Exploring the interplay between small and large scales movements in a neotropical small mammal

open access: yesMovement Ecology
We record and analyze the movement patterns of the marsupial Didelphis aurita at different temporal scales. Animals trajectories are collected at a daily scale by using spool-and-line techniques and, with the help of radio-tracking devices, animals ...

Economic Valuation of Renewable Transport Fuels: Evidence From Solar Fuel Willingness to Pay in Quebec, Canada

open access: yesThe American Journal of Economics and Sociology, EarlyView.
ABSTRACT The transport sector is one of the largest contributors to global greenhouse gas emissions, making it a key priority for climate mitigation policies. In this context, renewable fuels represent a promising complementary pathway to transport electrification, particularly due to their compatibility with existing internal combustion engine ...
