Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state

open access: yesJournal of Animal Ecology, EarlyView.
The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Biological invasions disrupt the relationship between size spectrum and trophic interactions in freshwater fish communities

open access: yesJournal of Animal Ecology, EarlyView.
Our study shows that non‐native species alter the relationship between the size‐spectrum slope and the predator–prey mass ratio (PPMR) in freshwater fish communities by occupying distinct trophic niches. Abstract The size spectrum, which describes the relationship between abundance (or biomass) and body size, is an ataxic approach that can provide ...

Contracts and Ownership Structures in the Bioeconomy: A Review of Their Design and Role in Innovation

open access: yesAustralian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Contracts and ownership structures play a critical role in fostering innovation in the bioeconomy. However, identifying which designs best promote bioresource circularity and collaboration remains challenging, as existing studies use diverse frameworks and are often limited to specific contexts or regions.

Measuring New Venture Legitimacy: A Multi‐dimensional Approach Using Computational Textual Analysis

open access: yesBritish Journal of Management, EarlyView.
Abstract Legitimacy is critical for the growth, survival and performance of ventures, yet efforts to measure legitimacy empirically typically focus on a single dimension of this multi‐dimensional construct. In this article, we develop a multi‐dimensional framework for measuring legitimacy using computational text analysis.
