Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

open access: yesEcological Entomology, EarlyView.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Do aphid endosymbiotic bacteria influence parasitoid searching behaviour through changes in aphid honeydew production?

open access: yesEcological Entomology, EarlyView.
Hamiltonella defensa infection increases honeydew production in certain aphid genotypes, potentially modifying aphid feeding behaviour. Parasitoid wasps, Aphidius ervi, are more attracted to honeydew from H. defensa‐infected aphids; though larger honeydew amounts may slightly deter searching.

An experimental examination of dispersal decisions made by flight‐capable heteropteran insects in urban stormwater pond conditions

open access: yesEcological Entomology, EarlyView.
Salty conditions in urban stormwater ponds can influence dispersal timing in species‐specific ways for actively dispersing aquatic heteropteran insects. Assaying multiple aspects of dispersal propensity, Hesperocorixa obliqua emigrated earlier in stormwater pond conditions while overall probabilities remained unchanged; Notonecta undulata emigration ...

Unlocking female CEOs' contribution to the internationalization of family‐controlled firms

open access: yesEuropean Management Review, EarlyView.
Abstract Are female CEOs better or worse than male CEOs for the internationalization of family‐controlled firms? By addressing this question, we draw on Upper Echelons Theory (UET) and complement it with insights from the Behavioral Theory of the Firm (BTF) to examine the moderating role of governance and ownership openness. Using a large panel of 2150

Skew Premiums Around Earnings Announcements

open access: yesFinancial Review, EarlyView.
ABSTRACT We examine skew premiums in equity options around earnings announcements. We use the realized returns to delta‐neutral risk reversal option spreads as a proxy for the skew premiums. We find skew premiums are economically significant around earnings announcements and are not explained by changes in variance risk premiums.
