Taxonomic and functional homogenization of butterfly communities along an urban gradient

Insect Conservation and Diversity, Journal Year: 2024, Volume and Issue: 17(2), P. 273 - 286

Published: March 1, 2024

Abstract Urbanization is a major cause of global insect declines, yet some species can persist, and even thrive, in cities. Research on butterflies frequently report reduced diversity urban habitats compared to rural ones, but less known about whether urbanization favours with specific functional traits. Further, few studies have evaluated leads the biotic homogenization butterfly communities, despite being reported for other taxa. Here, we investigate how community composition changes along an gradient by surveying 44 sites around Montréal, Quebec, Canada. We test hypothesis that communities are homogenized at taxonomic levels. found clear differences structure versus areas favouring few, highly abundant, non‐native species. These shifts were defined losses native richness abundance combined increases abundance. For most community, longer flight periods more common areas. Finally, levels as demonstrated reductions beta variation several key traits (wingspan, larval diet breadth, oviposition style) ones. Overall, this region support diverse homogenized. Since growing worldwide, better understanding arises what its consequences will be guiding future conservation efforts.

Functional traits drive the fate of Orthoptera in urban areas

Insect Conservation and Diversity, Journal Year: 2023, Volume and Issue: 17(2), P. 304 - 311

Published: Aug. 29, 2023

Abstract The replacement of natural areas due to urbanisation represents a major threat wildlife. Wild species may be classified according their response towards urban areas. Such responses lead persistence (exploiters and tolerant) or local extinction (avoiders) within cities, which in turn contributes shaping the assemblages found therein, usually specific sets ecological morphological traits. Here, we focus on Orthoptera as model group test hypotheses relationships between species' traits environments, using city Rome, Italy, study area. By compiling comparing checklists for two distinct time frames, assessed assemblage variation across last three decades revealed that is trait‐biased. Species with low mobility fertility, narrower—more specialised—climatic niches showed higher probability extinction. Our results point at both climate land use changes potentially drivers orthopterans' areas, suggesting strategies increase habitat preservation connectivity, mitigate climate‐change induced events, prove effective sustaining richer insect communities

Disentangling how urbanisation influences moth diversity in grasslands

Insect Conservation and Diversity, Journal Year: 2024, Volume and Issue: 17(2), P. 229 - 242

Published: March 1, 2024

Abstract Urban areas have profound impacts on local species diversity and composition through a set of intertwined changes in the environment. As world is rapidly urbanising while simultaneously facing biodiversity crisis, better understanding how urbanisation influences necessary. To test if moth whether acting directly or indirectly via urbanisation‐induced increased habitat isolation, smaller area, higher light pollution mowing intensity, we sampled moths with trapping 20 grasslands urban core city Darmstadt (southwestern Germany) surrounding area. Moth abundance decreased increasing urbanisation. Smaller area high intensity reduced abundance, other environmental variables including isolation had only indirect effects. High levels were associated which turn drove declines diversity. Urbanised sites favoured generalist differed compared to surrounding. The results show that reducing cities. negative effect further attenuated by fragmentation are both known drivers decline beyond. While itself often irreversible, preserving larger grassland could facilitate taxa around

Substantial urbanization‐driven declines of larval and adult moths in a subtropical environment

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(3)

Published: March 1, 2024

Abstract Recent work has shown the decline of insect abundance, diversity and biomass, with potential implications for ecosystem services. These declines are especially pronounced in regions high human activity, urbanization is emerging as a significant contributing factor. However, scale these traits that determine variation species‐specific responses remain less well understood, subtropical tropical regions, where urban footprints rapidly expanding. Here, we surveyed moths across an entire year protected forested sites gradient to test how caterpillar adult life stages (Lepidoptera) impacted by urbanization. Specifically, assess development affects total biomass caterpillars, abundance quantify richness phylogenetic macro‐moths development. Additionally, explore life‐history condition species' At community level, find decreases moth abundance. We also sharp response phylogeny, leading decrease species more sites. Finally, our study found smaller than larger environments, perhaps highlighting tradeoffs metabolic costs heat favoring over relative benefits dispersal moths. In summary, research underscores far‐reaching consequences on provides compelling evidence forests alone may not be sufficient safeguard biodiversity cities.

New Data Indicate Larger Decline in Morphological Diversity in Split-Footed Lacewing Larvae than Previously Estimated

Insects, Journal Year: 2025, Volume and Issue: 16(2), P. 125 - 125

Modern insect decline sparks interest in similar declines of the past. Neuroptera, group lacewings, has been suggested to have undergone after Cretaceous, and quantitative studies larval morphology supported this view. One groups within Neuroptera seeing a major is that split-footed Nymphidae. We here report 13 new specimens lacewings from about 100-million-year-old Kachin amber, Myanmar. explore how enlarging data set 60 expanding investigated morphological structures affect recognition decline. The expanded an increased morphospace, indicating lack saturation. is, therefore, likely even larger than so far anticipated for study head mouthparts provides strongest signal loss diversity, which feasible due direct coupling feeding ecology. Analysis trunk region cannot recover diversity. Sampling issues play role here: larvae less often well preserved, fossil are more early developmental stages constraints preservation.

Understanding antipredator strategies of insects: Human presence and escape behaviour in Odonata

Ecological Entomology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 18, 2025

Abstract Insects, like many organisms, face widespread human‐driven habitat transformations which are major threats to biodiversity. However, at the same time, transformed areas including cities increasingly being colonised by wildlife, sometimes serving as important refuges for vulnerable species. Most studies on traits that enable insects thrive in urban environments have focused morphology, physiology, and feeding or reproductive strategies, often overlooking behavioural traits, despite evidence from vertebrates showing tolerance towards humans is key wildlife successfully colonise cities. In this study, we tested effects of urbanisation, along with a range life‐history, environmental contextual humans—measured flight initiation distance—in 14 Odonata (dragonflies damselflies) species western Poland. We found escape distances were moderately repeatable within Urbanisation had generally weak effect behaviour; however, odonates delayed their sites high human presence. also tended increase observer’ starting distance species‐specific body size decrease perch height. Additionally, male more likely earlier than females. These results suggest can sense levels anthropogenic disturbance adjust behaviour accordingly. Furthermore, our findings indicate some basic patterns principles commonly reported vertebrates, such ability tolerate presence mass, may apply invertebrates. This implications understanding ecology evolution antipredator strategies conservation.
