1Ecological connectivity in fragmented agricultural landscapes and the importance of scattered trees and small patches显示文摘Background:Fragmentation and habitat loss can restrict species movement and reduce connectivity,negatively impacting biodiversity.Characterising the overall connectivity of an area can inform better management of human modified landscapes.Contemporary connectivity modelling methods seldom incorporate fine-scale movement patterns associated with movement between fine-scaled structural connectivity elements such as scattered trees,roadside corridors and small patches of habitat.This study aims to characterise connectivity within the Karuah-Myall catchments,a typical woodland ecosystem that is fragmented by agriculture,using least-cost path analysis and a graph-theoretic approach;it focuses on how fine-scaled vegetation such as scattered trees support connectivity.We mapped scattered(and paddock)trees within this agricultural landscape where the main human modified land use was pasture.We modelled connectivity for a general representative woodland species using an interpatch dispersal distance and gap crossing threshold,and resistance from different land cover types.The gap crossing distance threshold was used to model movement between fine-scaled vegetation features.We compared the least-cost paths modelled with and without scattered trees.Results:Our results show that by excluding scattered trees,least-cost paths across the cleared pasture landscape did not reflect the types of movement patterns typically observed from field studies,such as those associated with a foray-search strategy used by small and medium mammals and birds.The modelling also shows that the KaruahMyall catchments are well connected and provide value to biodiversity beyond the catchment borders,by connecting coastal vegetation to the Great Eastern Ranges national wildlife corridor initiative.Conclusion:Connectivity models that exclude fine-scale landscape features such as scattered trees and small,linear patches risk misrepresenting connectivity patterns.Models of regional-scale connectivity can be influenced by the presence or absence of even the smallest features,such as scattered trees.Darrel Chin Fung Tiang Andrew Morris Mathew Bell Christopher NGibbins Badrul Azhar Alex MLechner 2021Ecological Processes2021,10,1:1
2Impacts of 2 species of predatory Reduviidae on bagworms in oil palm plantations显示文摘综合害虫管理(IPM ) 广泛地在商业油手掌农业被练习。这个管理系统被打算在庄稼上由象结草虫那样的害虫昆虫最小化攻击的数字,以及在化学杀虫剂上与更少的相关性限制经济损失。在 IPM 的一个惯例是象食肉的昆虫那样的生物控制代理人的使用。在这研究,我们估计了食肉的生来的敌人的反应到害虫爆发和水应力,和文件潜在的害虫食肉动物的产地协会。许多 2 食肉的昆虫种类,也就是 Sycanus dichotomus 和 Cosmolestes picticeps (半翅类:Reduviidae ) ,被比较在油以内的结草虫爆发地点和 nonoutbreak 地点把种植园藏在掌内。我们也检验了产地特征两个都影响许多食肉的种类。我们发现了许多 C。picticeps 比在 nonoutbreak 地点在结草虫爆发地点是显著地更高的。在许多 S 没有重要差别。在爆发和非爆发地点之中的 dichotomus。两个都,种类否定地反应了在油手掌种植园浇应力。有关在食肉的昆虫丰富之间并且在 situ 产地质量特征的关系,我们的模型为 C 解释了 46.36% 变化。picticeps 并且为 S 的 23.17% 变化。dichotomus。两个都,食肉的昆虫的种类从在油手掌种植园种多重有益的植物繁荣。结果建议那 C。picticeps 能被用作一个生物代理人在油手掌种植园,而是 S 控制结草虫人口。dichotomus 不或很少为如此的生态系统服务有潜力。Syari Jamian Ahmad Norhisham Amal Ghazali Azlina Zakaria Badrul Azhar 2017Insect Science2017,24,2:0
