Relational values, motivations, and benefits drive community commitment to urban predator control for ecological restoration

open access: yesPeople and Nature, EarlyView.
Abstract Volunteers play a crucial role in urban ecological restoration, and in the Aotearoa New Zealand context, volunteer effort is a central tool used to drive landscape‐scale conservation outcomes. Here, we identify the motivations and benefits that drive community involvement and commitment to conservation initiatives, drawing on a unique case ...

From traditional practice to unsustainable exploitation: Fruit overharvesting on the endangered relict palm Jubaea chilensis

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Overharvesting of wild edible plants poses a growing threat to plant populations worldwide, particularly for slow‐growing species with limited regeneration. We quantified fruit extraction from the third‐largest known population of Jubaea chilensis—an endangered palm endemic to Chile—modeled the critical harvest threshold, and assessed consumer ...

Integrative Bioinformatics, Experimental Validation, and Interpretable Machine Learning Reveal Oxyresveratrol‐Mediated Protection Against Cadmium‐Induced Lung Adenocarcinoma‐Related Transcriptional Dysregulation

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Cadmium (Cd) is a toxic heavy metal strongly implicated in lung adenocarcinoma (LUAD) through mechanisms involving oxidative stress, epigenetic dysregulation, and chronic inflammation. This study aimed to identify Cd‐responsive genes associated with LUAD and to evaluate the protective effects of oxyresveratrol (O‐RES) against Cd‐induced ...

Nocturnal neighbors: exploring residents' perceptions of urban wildlife related to animal traits identified by camera traps and literature

open access: yesWildlife Biology, EarlyView.
Wildlife in urban areas is often a source of conflict, yet relatively few efforts have been directed toward fostering coexistence in these human‐dominated landscapes. While previous research has focused on socio‐demographic factors influencing perceptions of wildlife, the role of specific animal traits in shaping acceptance remains underexplored.
