Integrated species distribution modeling to assess species status and current and future threats for an imperiled amphibian

Conservation Science and Practice, EarlyView.
To understand the range‐wide drivers of Arizona Toad distribution and anticipate future changes, we combined 13 datasets covering distinct portions of the range in an integrated species distribution model. We estimate that the current occupied range is 1/4–1/3 of previously defined range boundaries and that increasingly dry conditions will lead to ...

Hydropower Regulation of Xingu River Discharge Structures Heterogeneous, Sector‐Specific Responses in Pacu Fisheries Along the River Continuum

Fisheries Management and Ecology, EarlyView.
ABSTRACT Hydroelectric dams are common in Amazonian tributaries under federal environmental licensing that requires long‐term fisheries monitoring. This study evaluated three fishing systems targeting “pacu” species (Serrasalmidae) in the Xingu River before, during, and after construction of the Belo Monte dam (2012–2023) across four river sectors ...

The former distribution of White‐tailed Eagles in Iberia, the Mediterranean and the Middle East: a case study of the importance of understanding historical distribution in informing current conservation and restoration interventions

Ibis, EarlyView.
The importance of considering historical data in developing conservation and restoration measures for individual species and for wider ecological restoration has been pointed out by recent reviews but often remains neglected in practice. This paper provides a case study illustrating the issue through a review of the former breeding distribution of the ...

Points vs. passes: A comparison between electric fishing techniques for sampling fish populations in upland headwater streams

Journal of Fish Biology, EarlyView.
Abstract Point‐abundance sampling by electric fishing (PASE) was compared with single‐pass (DF1) and triple‐pass depletion sampling (DF3) electric fishing on the same reaches of four headwater streams sampled over multiple years in the Ribble catchment, UK. Juvenile salmonids, mostly brown trout Salmo trutta with some Atlantic salmon S.

‘Civilizing’ Smallholders Through Oil Palm: The Politics of Subsumption Across Southern Mexico's Commodity Frontiers

Journal of Agrarian Change, EarlyView.
ABSTRACT While most frontier studies associate commodity expansions with dispossession, I argue that such expansions can also function as ‘civilizational’ projects aimed at overcoming traditional farming and creating new rural subjects better suited to the needs of capitalist development. Using a Gramscian approach to study subsumption, I analyse three

Shape of Water: Power Dynamics for Supply Chain Resilience

Journal of Supply Chain Management, EarlyView.
ABSTRACT The world is facing climate change‐driven disruptions such as extreme weather events, which affect nature as well as firms and their supply chains. Nonetheless, little is known about how supply chain players shape their socioecological resilience, including from a power perspective.

How Alliances Build Innovation Capabilities but Narrow Their Redeployment in Amazonian Community‐Based Enterprises

R&D Management, EarlyView.
ABSTRACT Research on strategic alliances often treats supplier capability development as an outcome, but rarely asks which capabilities are built or what they can be used for. We address this through an embedded single‐case study of a lead‐firm‐orchestrated network in the Brazilian Amazon, comprising six community‐based enterprises (CBEs) supplying ...
