Linking eBird data with high spatiotemporal remote sensing products to estimate occupancy of bird populations across the island of Ireland

open access: yesIbis, EarlyView.
The vast increase in biodiversity data generated through citizen science initiatives, alongside a growing suite of remote sensing products and advanced modelling tools, has opened new avenues for rapidly, accurately and efficiently monitoring species trends to inform conservation, management and policy.

Under the cover of darkness: Foraging behaviour increases on cloudy, new moon nights in a pelagic seabird

open access: yesIbis, EarlyView.
While many visual predators feed exclusively during the day, others exploit foraging opportunities at night, although the efficiency with which they do so is strongly influenced by ambient light levels. We investigated the influence of variation in nocturnal light on the foraging behaviour of a small pelagic seabird, the European Storm‐petrel ...

Floral resource availability and surrounding land cover influence bumble bee community composition in an agricultural landscape

open access: yesInsect Conservation and Diversity, EarlyView.
Multispecies occupancy models indicated that the occurrence of bumble bees was associated with local floral resources as well as the landscape surrounding a site within 1.6 km. Estimated species richness was greater at sites with more forest cover and lower at sites with more corn and soybean agriculture in the surrounding landscape.

A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Genetic Determination of Maternal Behaviour in Pigs

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT In sows, maternal behaviour is a commercially important trait which affects sow and piglet welfare and the quality and safety of human‐animal interactions, especially if free farrowing of sows without crates is in place. The aim of this study was to evaluate maternal behaviour and to estimate its quantitative genetic parameters in Swiss ...

Modelling relationships between juvenile brown trout (Salmo trutta L.) density and landscape characteristics: Integration of electrofishing data and spatial data to assess population status

open access: yesJournal of Fish Biology, EarlyView.
Abstract Brown trout (Salmo trutta L.) are ecologically and economically important, but like many salmonids their populations are declining. Trout exhibit a high level of phenotypic plasticity, ranging from freshwater residency to anadromy. This complexity causes problems for assessment and constrains application of adult catch‐based assessment methods

Asymmetric Pass‐Through and Competition

open access: yesThe Journal of Industrial Economics, EarlyView.
ABSTRACT We study the retail price pass‐through of four major tax changes in petroleum products using daily pricing data from gas stations on small Greek islands. We find that (i) the pass‐through of the tax hikes is five times higher than for the tax decrease, (ii) the pass‐through of the tax hikes increases with competition, while that of the tax ...

Dynamic Probit Models With Network Interdependence and Unobserved Heterogeneity With an Application to Multinational‐Firm Participation in China

open access: yesJournal of Regional Science, EarlyView.
ABSTRACT In many areas of regional/spatial economics, we are faced with analyzing discrete dynamic choice problems of economic agents interacting with some network structure through general equilibrium, input‐output links, or strategic interaction. Stochastic estimating equations for such problems can be difficult for many practitioners to estimate ...
