Insect ecology and conservation in urban areas: An overview of knowledge and needs

Insect Conservation and Diversity, Год журнала: 2024, Номер 17(2), С. 169 - 181

Опубликована: Март 1, 2024

Abstract Urban expansion across the globe profoundly impacts local biodiversity. The growing body of urban ecology research on animals has largely focused mammals and birds, whereas knowledge insect conservation in areas remains limited. To anchor this Special Issue (SI), we have taken a broad approach to editorial conducted structured literature search set scene. We provide here an overview existing reviews conservation, indicate where articles included SI contribute developing our understanding point priority for further investigation. Key themes (at individual, species, and/or community level) include influence habitat quality, quantity land use type diversity; anthropogenic pollution (for instance, heat, noise, light chemicals); connectivity changes structure density genetic diversity. Insect diversity abundance broadly decline with loss habitat. Beyond this, variation responses different taxa, or regions, methodological limitations individual studies make it challenging identify general patterns. environments should focus applying ecological theory understand patterns; investigating interactions between climate change contexts; identifying novel biodiversity; addressing harmonising approaches; exploring social historical factors must also consider into how best communicate value insects humans.

Larger cities host richer bee faunas, but are no refuge for species with concerning conservation status: empirical evidence from Western Europe.

In the context of worldwide biodiversity and wild bee decline, it is increasingly important to better understand effect land-use changes on communities at a global scale. To do so, we studied city area urban green spaces layout species richness community composition, as well with an unfavorable UICN conservation status. This study was based large European dataset encompassing 20 cities from France, Belgium Switzerland. We found mean in 96 ± 48 (SD), showing that this highly variable among cities. The main factor positively influencing city. Conversely, not significantly related total given city, measured spatial extent parks, wastelands other semi-natural habitats, excluding private gardens. Species status were quite scarce environments, especially when compared Red List Bees, could link their presence either or space area. Dissimilarities compositions associated any characteristics dissimilarity composition mainly driven by rarest species, most common ones majority sampled. Overall, these results emphasize larger host more but are no refuge for concerning Thus, stakeholders encouraged design favor support communities, perhaps mitigate established ecological filter.

From cities to refuges for pollinators: Urban practices for enhancing pollinator habitats in changing landscapes

Journal of Applied Ecology, Год журнала: 2025, Номер unknown

Abstract Urban built‐up lands and their expansion significantly reduce green areas, where pollinators should find flowers for feeding places nesting, threatening existence. Reversing the decline of is a global goal, as they are multi‐taxa guild linked to essential ecosystem services sustain functioning. We aimed highlight frontier pollinator support, by evaluating emerging practices improve biodiversity in urban contexts, that could integrate consolidated actions already use. also clarified role society this context research gaps. For it crucial provide adequate nutrition nesting substrates. This can be achieved valorising existing resources, tuning pollinator‐friendly management ( e.g ., deadwood, no mowing) providing human‐made solutions. Nutritional resources assure sown flower survival across years ornamental plants fill gaps blooming phenology rewards quality.

Enhancing Lasioglossum (Homalictus) dotatum (Hymenoptera: Halictidae) habitats: The role of rock gravel in bare soil landscapes

Austral Entomology, Год журнала: 2025, Номер 64(2)

Опубликована: Апрель 14, 2025

Abstract Native bee populations are generally in decline, and although their conservation needs recognised, habitat requirements for the majority of species remain unknown. Many construct nests underground, including native Australian Lasioglossum (Homalictus) dotatum . However, like most ground‐nesting bees, nesting ecology, particularly substrate preferences soil surface requirements, remains poorly understood. To address this knowledge gap, study examined whether L. prefers bare sand or amid rock gravel treatment influences nest‐site selection. Experiments were conducted using 24‐L pots Bassendean sand, placed near active aggregations. Ten had a layer gravel, while remaining 10 left bare. Within each treatment, half contained untreated steam‐treated to remove potential contaminants. This design tested certain conditions features when selecting nest sites. Results showed that female preferentially with over those suggesting cover may create more favourable environment by moderating temperature, retaining moisture, providing structural stability entrances. Additionally, females preferred possibly indicating factors associated soil, such as microbial presence organic residues, deter nesting. advances our understanding behaviour provides framework creating pollinator‐friendly spaces identifying key influence mechanisms driving preference unknown, highlighting need further research distinguish roles hygiene, properties chemical cues

Consequences of intraspecific competition for floral resources in heterogeneous landscapes for eusocial bees

Harnessing Community Science to Support Implementation and Success of Nature-Based Solutions

Sustainability, Год журнала: 2024, Номер 16(23), С. 10415 - 10415

Community science (CS), a type of community-based participatory research, plays crucial role in advancing wide-reaching environmental education and awareness by leveraging the collective power volunteer participants who contribute to research efforts. The low barriers entry well-established methods monitoring have potential enable community participant involvement applications nature-based solutions (NbS). However, better understanding current state approaches within NbS could improve feasibility for researchers practitioners implement NbS. Based on literature, we discern five that support NbS: (1) Environmental determine baseline conditions; (2) Involvement development planning through discussions workshops (i.e., co-design NbS); (3) Using existing CS databases design implementation; (4) Determining impacts measuring effectiveness NbS; (5) Participation multifunctional activities. While there are various avenues participation, find CS-driven actions involve observing, measuring, assessing parameters conditions over time) emerges as cornerstone planning, implementing, maintaining success As proliferation implementation continues, future work integrate studies has potential, albeit far from guaranteed, place-based local societal ecological outcomes.
