Managing for resilience with ecological structure: Portfolio effects in the Laurentian Great Lakes

Frontiers in Ecology and the Environment, EarlyView.
Combined effects of global change, including land conversion, biological invasions, and overexploitation, have degraded the resilience of ecosystems and the services they provide. Here, we identify key ecological structures and processes that can be targeted by management to improve resilience at scales ranging from single species to entire landscapes.

Beyond Tobacco Prevention: The Effects of Tobacco 21 Laws on Young Adults' Body Weight

Health Economics, EarlyView.
ABSTRACT Tobacco 21 (T21) laws effectively reduce youth tobacco use by preventing initiation. This study examines their impact on body weight among young adults aged 18–20. Using 2009–2019 Behavioral Risk Factor Surveillance System data and a two‐way fixed‐effects difference‐in‐differences (DID) design, we find limited evidence of broad weight changes ...

Holistic bone developing microenvironment engineered apoptotic extracellular vesicles recapitulate multidimensional developmental signatures in adult and senile bone repair

Interdisciplinary Medicine, EarlyView.
The developing bone was identified as an M2a‐like macrophage driven immune microenvironment with multidimensional developmental signatures. hME‐ApoEVs were successfully fabricated via stimulating the M2a‐like developing microenvironment in vitro and confirmed its recapitulation of developmental features.

Behavioral responses of black bears to human presence and infrastructure in Yosemite National Park

The Journal of Wildlife Management, EarlyView.
Using GPS collar data from black bears in Yosemite National Park, we examined how bear spatiotemporal activity in relation to human development shifted during the COVID‐19 park closure in 2020. In the absence of visitors, bears maintained consistent landscape‐scale space use but altered fine‐scale spatial and temporal behaviors.

Catch allocation in a shared fishery with a minimally managed recreational sector

A prevalent problem in shared fisheries is competition between commercial and recreational fishers for access to a resource that is subject to increasing utilisation pressure. For most shared fisheries in New Zealand, the commercial sector is efficiently

Comparative Transcriptomic Analysis of Male and Female Gonads in the Zig-Zag Eel (Mastacembelus armatus)

Fishes
The zig-zag eel (Mastacembelus armatus) is a unique economic fish species in China and exhibits significant dimorphism of male and female phenotypes. Cultivating all-male seedlings can significantly improve production efficiency.

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds

The Journal of Wildlife Management, EarlyView.
Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Economic valuation of recreational fishing in Western Australia

Allocation of fish resource is a controversial subject. Decision making is partly made difficult by the lack of knowledge on recreational fishing preferences and the value of fishing opportunities.
