Seasonal shifts in network structure and species roles in a tropical island plant–flower visitor community Cambios estacionales en la estructura de la red de interacciones entre plantas y visitantes florales y en los roles de las especies en una comunidad insular tropical

open access: yesInsect Conservation and Diversity, EarlyView.
Constant visitation rates across the flowering season masked major shifts in plant and flower visitor interaction structure, specialization, species roles and trait‐driven patterns shaping interaction intensity. Plants and flower visitors changed ecological roles over time, with native flower visitors playing key roles in maintaining network cohesion ...

Taxonomic and methodological biases in saproxylic beetles: Body size, trophic group and detection probability

open access: yesInsect Conservation and Diversity, EarlyView.
Smaller saproxylic beetle species are described later and appear later in georeferenced databases, demonstrating a persistent body‐size bias that contributes to Linnean and Wallacean shortfalls. Trophic group, not body size, is the primary driver of detection probability in standardised flight‐trap surveys, with sapro‐xylophagous species detected most ...

A Quantile Model of Firm Investment

open access: yesInternational Economic Review, EarlyView.
ABSTRACT Are firms risk averse? We propose a dynamic model of firm investment under uncertainty that captures firms' risk attitudes through quantile preferences. The firm maximizes its present value, defined as current profits and investment plus the discounted value of the τ$\tau$‐quantile of its value next period.

Task Complexity Effects on Writing Processes and Correlations With Text Features

open access: yesInternational Journal of Applied Linguistics, EarlyView.
ABSTRACT Research on task complexity (TC) effects on second language (L2) text features is abundant and has contributed critical insights. Comparatively, less is known about how L2 writers respond cognitively to diverse TC conditions or about potential effects of such processing activity on the characteristics of the texts produced.
