Abstract:Birds are an important part of the agricultural landscape, as having nature value, but also as pest control agents and bio-indicators for the health of the environment. Here we look at linear non-crop elements in agricultural areas as a potential source of food for nestlings of avian species. We measured invertebrate availability as it relates to structural complexity at the local and landscape levels in three counties in central Illinois. Invertebrates were measured with taxonomic diversity, abundance, and estimated biomass during spring of 2012 and 2013. Our study shows that easily modifiable field edge characteristics have the greatest impact on invertebrate diversity and abundance, as compared to field and landscape features. This finding shows that a potential invertebrate food source as measured by both diversity and biomass, may be easily enhanced without changes to agricultural practices.

“…So far, edge effects anomalies in the area due to the interaction of two or more ecosystems. However, many researchers studied edge effects to describe succession processes (Liu et al 2018), the complexity of interactions (Evans et al 2016), and the progress of change and the impact of an ecosystem (Ewers et al 2013). Areas with a variety of traditional agricultural management illustrate the complexity of the plant and animal communities within them.…”

Abstract. Kurnianto AS, Haryadi NT, Dewi N, Miftachurrohmi, Rohmana A, Amal GI, Septiadi L, Firdaus AS, Magvira NL. 2023. Edge effects at multifunctional agro-landscapes in Jember, Indonesia, on the augmentation of butterfly diversity. Biodiversitas 24: 2231-2241. Butterflies are important pollinators and bioindicator communities in agro-landscapes. Assessing changes in butterfly communities, such as abundance and diversity, is essential in evaluating the response of butterflies to ecosystem disturbance. However, edge effects on agro-landscapes are highly influenced by land management. This study aims to objectively investigate the interactions between agroforestry management, including mono-shade, complex, and agroforestry-monoculture systems, with butterfly diversity to assess the impact of edge effects on butterfly communities. Sampling was conducted using Van Sommeren traps (T=150 cm; D=30 cm) baited with fermented bananas. Each trap was hung three meters high on a tree with three replicates in one location. Within 24 hours, the butterflies were collected, dried in an oven for 3x24 hours, and identified. The ecological indices were calculated using PAST 3.26, including the Shannon-Wiener index, the Simpson dominance index (D), the Simpson diversity index (1_D), the Margalef index, and the Evenness index. Therefore, 61 specimens, including 59 Nymphalidae and 2 Pieridae, were successfully collected. There are Nympahlidae families: Amathusia phidippus Linnaeus, 1763 (1), Elymnias casiphone Hübner, 1824 (2), Elymnias hypermnestra Linnaeus, 1763 (2), Euthalia aconthea Cramer, 1779 (1), Euthalia monina Fabricius, 1787 (1), Junonia atlites Linnaeus, 1763 (1), Junonia iphita Cramer, 1782 (1), Lethe europa Fabricius, 1775 (1), Melanitis leda Linnaeus, 1758 (24), Melanitis phedima Cramer, 1782 (4), Mycalesis fuscum Felder, 1860 (2), Mycalesis horsfieldi Moore, 1892 (1), Mycalesis janardana Moore, 1857 (6), Mycalesis nala Felder, 1859 (1), Mycaleses perseus Fabricius, 1775 (1), Mycalesis sudra Felder, 1867 (2), Orsotriaena cinerea Butler, 1867 (1), Orsotriaena medus Fabricius, 1775 (2), Polyura athamas Drury, 1773 (3), Polyura schreiberi Godart, 1824 (1), Tanaecia trigerta Moore, 1857 (1). There are families Pieridae: Leptosia nina Fabricius, 1793 (1), Eurema blanda Boisduval, 1836 (2). Comparison between complex and monoculture sites showed substantial differences. Meanwhile, there was no significant difference between mono-shade and monoculture sites. Butterfly diversity at the three locations was categorized as moderate. The highest diversity was observed in mono-shade sites. The three similarity indices showed that the agroforestry complex and monoculture locations have high similarity. Melanitis leda Linnaeus, 1758 was found in 3 sites and commonly found in complex sites (16), followed by monoculture (6) and mono-shade (2). This study indicated that edge effects have a significant influence, especially on the diversity of butterflies in the monoculture area.

Agricultural intensification has significantly impacted habitat structures in agricultural landscapes and is one of the main drivers of biodiversity decline, especially in farmland birds. Birds are considered to reflect well the trends in other biodiversity elements and are therefore often used as indicator species. We studied common pheasant (Phasianus colchicus) brood habitat use in a small-grain-dominated farmland in southern Finland. The broods significantly preferred field margins compared to their availability. The importance of field margins was underlined, as 68% of pheasant brood observations in grain fields were within a 25-m-wide zone from the field edge, despite the availability being only 40% of the field area. Our results support the idea that field margins and their proximity act as possible biodiversity reservoirs even in intensive farming systems. Increasing the amount of field margins can be an effective management method when aiming to improve success of common pheasant broods while simultaneously benefitting farmland biodiversity. Identifying key habitats and landscape features that allow the co-existence of biodiversity and effective food production is crucial when aiming to halt the ongoing biodiversity collapse.
