Optimal Control Applications and Methods, EarlyView.Schematic representation of the proposed disease transmission model incorporating vertical transmission, saturated incidence, and nonlinear treatment. The study combines theoretical analysis, bifurcation and stability investigations, and optimal control techniques to evaluate prevention and treatment interventions.

Both density‐ and frequency‐dependent effects determine plant growth in a dune heath ecosystem
Oikos, EarlyView.We tested the hypothesis that both density‐ and frequency‐dependent interactions play important roles in determining plant growth in a dune heath ecosystem at several levels of available nitrogen. Plant growth was measured using the pin‐point method in a five‐block experiment with four nitrogen levels.

Oikos, EarlyView.Many mechanisms can lead to successful plant invasion, but their importance is often context dependent. One such mechanism is allelopathy: chemical inhibition of neighbouring plants. The importance of allelopathy may be mediated by soil microbiota and environmental conditions, and depend upon the species or functional group affected.

Oikos, EarlyView.Seed dispersal by frugivores is a central process linking plant reproduction, animal foraging, population persistence, and ecosystem resilience. Currently, the spatial template sustaining these interactions is rapidly reconfigured by habitat loss and fragmentation promoted by human activity.

Public Administration and Development, EarlyView.ABSTRACT This article explores the management adaptation strategies non‐governmental organizations (NGOs) managers employ in order to operate in repressive political environments. It answers the question: how do NGO managers initiate, manage and sustain internal change when the political/regulatory environment changes?

, 2003 The impact of commonly used organophosphate (chlorpyrifos, methamidophos), carbamate (carbaryl), and pyrethroid (cypermethrin) insecticides on insect natural enemies was compared with that of a nucleopolyhedrovirus (Baculoviridae) of Spodoptera ...

Identifying knowledge barriers to agroforestry adoption and co‐designing solutions to them
People and Nature, EarlyView.Abstract Compared to monocultures, agroforestry can promote biodiversity, ecosystem functioning and climate resilience, whilst maintaining or enhancing production and profits. Despite this, uptake in temperate regions remains low. Knowledge gaps amongst land managers are a primary barrier to uptake, but little is known about which aspects of ...

, 2008 1. Most communities of insect herbivores are unlikely to be structured by resource competition, but they may be structured by apparent competition mediated by shared natural enemies. 2.

Unpacking the task of synthesis when weaving knowledge systems for biodiversity assessments
People and Nature, EarlyView.Abstract The pivot towards evidence‐based conservation since 2000 has inspired global environmental assessments to gather evidence across multiple knowledge systems, including through co‐production with Indigenous Peoples and local communities. Knowledge co‐production is highlighted as a strategy for transformative change towards a just future that ...
