Agricultural intensification is widely recognised as a primary driver of pollinator loss, but the success land-management actions designed to remediate its impact often mixed. Payments farmers increase habitat connectivity or availability floral and nesting resources may only result in short-term gains even unintended consequences. The reasons lie changes interaction networks competition intensity that remain poorly understood. Models pollination service typically implicitly assume population dynamics are regulated by nest-site availability, though empirical evidence suggests occupancy likely at least part dependent on resource availability. To investigate consequences for coarse-grained agricultural landscapes we extended an established model bees combining optimal foraging dynamics, include new functions depletion realistic colony dynamics. We find intra-specific occurs late season forcing forage underutilised sites situated further towards their range limits. A lower rate energy acquisition ultimately limits size peak delays timing. Consequently, can limit distribution while same time contributing more stable efficacious service. Although was not found be important establishment success, effect hunger gap early indirectly influences later leading complex outcomes.

Corymbia calophylla (Marri) (K. D. Hill & L. A. S. Johnson) (Myrtaceae) is a major resource for native bees in the southwest western Australian biodiversity hotspot

Pacific Conservation Biology, Journal Year: 2024, Volume and Issue: 30(6)

Context A theoretical paradigm proposes that certain species can serve as ‘keystone species’ or ‘magnets’, being particularly important for biodiversity. Aims We present evidence in the context of supporting Indigenous native bees, this is indeed case tree Corymbia calophylla (Marri), a Myrtaceae endemic to southwest Western Australia. Methods To assess role C. resource we collated number recorded from surveys across 16 sites, and specimens lodged WA Museum. Its capacity support wild bees was assessed abundance visiting (total relative other plants visited) 24 sites. Key results visited by 81 often main, only, plant visited. It blooms at crucial time when most have finished flowering end summer. Conclusions argue represents landscape bees. Implications Protection management likely be preservation bee

Motivations for farmers’ participation in agri-environmental scheme in the EU, literature review

Open Agriculture, Journal Year: 2024, Volume and Issue: 9(1)

Published: Jan. 1, 2024

Abstract Agri-environmental schemes (AESs) play a pivotal role in aligning agricultural practices with environmental objectives, promoting sustainable land management, and conserving biodiversity. This article presents comprehensive synthesis of recent advancements AES research within the European Union context, focusing on ecological, economic, socio-political dimensions. Through systematic review literature published since 2013, we identify emerging trends, gaps, priorities, providing novel insights into effectiveness. We examine factors that influence participation such as biodiversity, habitat fragmentation, ecosystem services. also explore economic influencing farmer participation, including financial incentives, income stability, cost–benefit analysis. Furthermore, investigate dimensions AES, institutional frameworks, stakeholder engagement, trust programme implementation. Key findings highlight need for adaptive management strategies, incentive structures aligned inclusive governance mechanisms to enhance Our underscores importance context-specific approaches account farm characteristics, socio-economic factors, arrangements. Practical implications policymakers, practitioners, stakeholders are discussed, emphasizing evidence-based policymaking iterative learning agriculture conservation.
