Evaluating a structured expert elicitation approach for adaptive conservation management based on lessons from five years in practice

open access: yesConservation Biology, EarlyView.
Abstract Adaptive management of threatened species relies on having ex ante estimates of species’ responses to different interventions. Structured expert elicitation is often used to generate these estimates, but comparisons of these expert‐predicted outcomes with observed results are rare.

Solvent-free mechanosynthesis of Schiff bases derived from thiadiazole with potential application in sensing ionic species and NLO applications

open access: yesChemical Physics Impact
In this work, we report the solvent-free mechanosynthesis of three Schiff bases (SBs) derived from 1,3,4-thiadiazole covalently bonded to indole (Th-In), quinoline (Th-Qn) and triphenylamine (Th-TPA) groups.

Escarabajos estercoleros del Ecuador (Coleoptera: Scarabaeinae), estado del conocimiento ecológico

open access: yesSiembra, 2023
Ecuador alberga una asombrosa cantidad de ecosistemas y especies. Sin embargo, los cambios antropogénicos y el cambio en el uso de la tierra son los principales impulsores de la pérdida de biodiversidad en muchos grupos taxonómicos; entre ellos, los Scarabaeinae o escarabajos estercoleros, un excelente taxón para estudiar la diversidad alfa, beta y ...

Insights from three decades of IUCN Red List assessments catalyzing shark, ray, and chimaera conservation

open access: yesConservation Biology, EarlyView.
Abstract The International Union for Conservation of Nature (IUCN) Red List of Threatened Species is a critical measure of global aquatic and terrestrial biodiversity status. It is also the basis for the Red List Index, which tracks extinction risk over time.

A Review and Critique of Methods and Knowledge Gaps in Quantifying Spillover Effects from Protected Areas

open access: yesConservation Biology, EarlyView.
Abstract The sustainability of area‐based conservation initiatives depends on their value to society. Conservation often focuses inside protected areas, but the impacts of protected areas beyond their boundaries (spillovers) are critical for their social license.

Synthesis of Pollinator‐Friendly Management in European Protected Areas

open access: yesConservation Biology, EarlyView.
Effectiveness of pollinator‐friendly management in European protected areas. Abstract Pollinators are important to humans and nature due to their role in ecosystem functioning and services. Research on the effects of pollinator management in protected areas is insufficient compared with that on farmlands and urban areas, potentially hindering ...

Transitional analysis for multi-objective operative improvement of reformate quality and hydrogen production from a naphtha catalytic reforming process

open access: yesHeliyon
The hydrogen produced (H2) in the Catalytic Naphtha Reforming (CNR) is important in quantity and quality, for the feedback of the process and for supplying the hydrotreatment processes in current refineries.

Risk reduction, rangeland use, and the future of human–carnivore coexistence

open access: yesConservation Biology, EarlyView.
Abstract Efforts to reduce livestock losses to large carnivores are widely regarded as essential for promoting human–carnivore coexistence. Predator‐proof enclosures, compensation programs, improved livestock guarding, and real‐time predator alert systems can reduce depredation and retaliatory killing while enhancing pastoralist livelihoods.
