Control failure risk, resistance and enzymatic activity of neurotoxic insecticides in Brazilian populations of Leucoptera coffeella (Lepidoptera: Lyonetiidae)

open access: yesPest Management Science, EarlyView.
Bioassays of 36 Leucoptera coffeella populations revealed resistance to neurotoxic insecticides, control failures of ≤62.9% and enzyme activity variation, with particularly high GST and low AChE levels. Abstract Background Leucoptera coffeella is a key pest of coffee crops in Brazil, causing significant damage by mining coffee leaves.

Assessing group size and the demographic composition of a canopy‐dwelling primate, the northern muriqui (Brachyteles hypoxanthus), using arboreal camera trapping and genetic tagging

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
We combined arboreal camera trapping and non‐invasive genetic tagging to estimate group size in the critically endangered northern muriqui (Brachyteles hypoxanthus) in Brazil's Atlantic Forest. Both methods provided complementary insights into group size and demographic structure, while differing in their cost‐effectiveness and sampling constraints ...

Members Only—The Emergence of the Business Family as a Professionalized and Differentiated Organizational System

open access: yesSystems Research and Behavioral Science, EarlyView.
ABSTRACT The importance of business families is increasingly gaining attention. However, to truly understand business families and their dynamics, they must be viewed as distinct systems. Since this area has received limited scholarly focus, we argue that forming a new system is more than just an extension.

The Interactional Pathways of Mass Killings: Toward a Novel Understanding of Rampage School Shootings

open access: yesSymbolic Interaction, EarlyView.
Rampage school shootings, where students go to their own school to randomly kill classmates, teachers, friends, and strangers, are among the most drastic types of human behavior. While research increasingly points to interaction dynamics as being key for the emergence of crime and violence, scholars have not yet systematically studied interaction ...
