Frugivory‐mediated trophic cascades: how apex predators can shape the recruitment of a fleshy‐fruited tree

Oikos, EarlyView.
The recovery of large carnivores offers unique opportunities to study their cascading impacts on plant population dynamics. Medium‐sized carnivores, both prey and seed dispersers, are suppressed by apex predators, indirectly increasing seed‐eating rodent's populations and potentially altering plant establishment.

Multiple scales of fear: foraging behaviour of white‐naped jays in semiarid landscapes

Oikos, EarlyView.
Animals must constantly balance the need to find resources with the risk of predation. Not only avoiding direct encounters with predators but also assessing the overall risk of their environment using cues, social information or habitat traits at multiple spatial and temporal scales.

Dynamic performance improvement method of energy storage DC/DC converter for grid-connected wind turbine with energy storage

电力工程技术
The internal storage system of a wind turbine usually needs to be connected to the DC bus using a DC/DC converter. However，due to the poor dynamic performance of the energy storage DC/DC converter using traditional PI control，it is easy to cause a large ...

Discovery of Precursor LBV Outbursts in Two Recent Optical Transients: The Fitfully Variable Missing Links UGC 2773-OT and SN 2009ip

, 2010
We present progenitor-star detections, light curves, and optical spectra of SN2009ip and the 2009 optical transient in UGC2773 (U2773-OT), which were not genuine SNe.

Large, rugged and remote: The challenge of wolf–livestock coexistence on federal lands in the American West

People and Nature, EarlyView.
Abstract The expansion of grey wolves (Canis lupus) across the western United States, including on public lands used for extensive livestock grazing, requires tools and techniques for reducing wolf–livestock conflict and supporting coexistence. We examined approaches used on forested lands managed by the U.S.

Unveiling human–wildlife interactions in the context of livestock grazing abandonment and the return of large carnivores, ungulates and vultures: A stakeholder perspective

People and Nature, EarlyView.
Abstract Pastoral practices remain a widespread economic activity across European mountain regions. However, the viability of this activity may be threatened by the recovery of large wild vertebrates associated with passive rewilding, leading to the so‐called human–wildlife conflicts.

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan

People and Nature, EarlyView.
Abstract Kazakhstan is recognized as a key stronghold for the grey wolf (Canis lupus). Nonetheless, the wolf status and the dynamics of human‐wolf coexistence in the region remain poorly understood. This study aims to fill that gap by exploring current attitudes towards wolves in Kazakhstan and identify the underlying drivers of these attitudes.
