Drivers of cultivated and wild plant pollination in urban agroecosystems

Basic and Applied Ecology, Journal Year: 2023, Volume and Issue: 72, P. 82 - 92

Published: Sept. 30, 2023

Pollination is a vital ecosystem service in urban agriculture. Yet the environmental drivers of both crop and wild plant pollination agroecosystems are still not well understood. experiments involve manipulation pollen transfer between plants, for instance, to study effects pollinators on fruit seed production (pollination service). In this study, we conducted exclusion experiment using four experimental plants: two cultivated species, strawberry (Fragaria x ananassa) chili pepper (Capsicum frutescens), buttercup (Ranunculus acris) clover (Trifolium pratense). We placed plants over 20 days 13 community gardens Munich, Germany. compared mass "open" "bagged" flowers tested effect biotic factors (floral resources pollinator diversity) abiotic (urbanization, microclimate) (fruit mass) species. For (F. ananassa C. found that were positively correlated with temperature diversity. (R. acris T. pretense), floral abundance was negatively related R. but pratense mass. summary, parameters affected species studied here different ways, suggesting there may be synergies trade-offs what promote overall communities. Our results suggest gardeners can potentially increase services certain garden by providing pollinating insects.

Uncovering historical roots of nature-based solutions: Christian Ludwig Krause's approaches to restoring degraded land in an 18th-century European landscape

Nature-Based Solutions, Journal Year: 2023, Volume and Issue: 4, P. 100094 - 100094

Nature-based solutions (NBS) represent a recent umbrella concept to tackle land degradation and other urgent challenges. The has deep, often-hidden historical roots. To shed light on these origins, this paper examines 18th-century approaches combat in central European landscape, as documented 1773 book by Christian Ludwig Krause. First, sources overexploitation of forests grasslands Brandenburg (now part Germany) are examined illustrate major challenges that period. Then, an analysis Krause's identifies the problems he addressed proposed response. Krause astutely diagnosed interaction different uses led loss or then wind erosion severely affected agricultural fields. He identified reduced flower availability due overgrazing threat bees honey production. His main recommendations include restoration oak woodlands, establishment tree plantations, recovery degraded sandy areas, planting hedgerows living fences, bee gardens. justified highlighting negative socioeconomic consequences degradation, such timber shortages yields. farmers stakeholders directly, illustrating expected economic benefits interventions, including for well-being future generations. ideas stand out several reasons: (i) they underpinned clear-sighted understanding natural components processes, combined with practical experience; (ii) treated social-environmental phenomenon, responsibility various their solutions, supported reasoning; (iii) linked land-use systems local regional scales, even incorporating urban-rural coupling nutrient cycles. Most his suggestions meet present-day criteria NBS. Two aspects work fall outside NBS framework: data efficiency proposals missing biodiversity gains not explicitly included - although many them would result improved biodiversity. can be considered pioneer NBS, systems-based thinking serving model today, was also ecological sustainable use.

Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment

Biodiversitas Journal of Biological Diversity, Journal Year: 2024, Volume and Issue: 25(1)

Abstract. Pasaribu DN, Rizali A, Tarno H, Priawandiputra W, Johannis M, Buchori D. 2024. Agricultural landscape composition alters ant communities in maize fields more than plant diversity enrichment. Biodiversitas 25: 205-213. Fragmented natural habitats human-modified landscapes play a crucial role conserving biodiversity. Ants, as keystone species, are integral to terrestrial ecosystems, making it essential comprehend the factors influencing their survival. This study investigates impact of agricultural and enrichment (flowering plants) management on shaping (Zea mays L.) fields. The research occurred surrounded by other crops, semi-natural habitats, housing areas Malang District, East Java, Indonesia. four were divided into control treatment plots, considering parameters, particularly Class Area (CA) Number Patches (NP), measured within 500 m radius. around was characterized manually digitizing land use. Six types employed this study: wild cosmos (Cosmos caudatus), white buttercup (Turnera subulata), sunflower (Helianthus annuus), long bean (Vigna unguiculata), ornamental (Arachis pintoi), coral vine (Antigonon leptopus). dry season (April-July 2022) wet (September-December 2022). Ant sampling conducted using pitfall traps and, based generalized linear models, revealed that did not affect species richness, abundance, or ants. Landscape positively influenced richness but negatively impacted composition, number habitat patches. Maize crop age also affected beta diversity. Wet found have negative effect In conclusion, proportion contribute significantly

Reimagining urban habitats to benefit people and nature

Australian Zoologist, Journal Year: 2024, Volume and Issue: 43(4), P. 495 - 501

Published: April 22, 2024

ABSTRACT Urbanisation is a leading cause of global biodiversity loss, imposing the most rapid and ecologically damaging impacts any human driven land-use change. Despite trend decline, urban nature provides many health, wellbeing workplace productivity benefits to city dwellers. Hence, there an urgent need return cities not only conserve biodiversity, but also maintain experiences nature. To meet this challenge, are currently significant attempts re-green improve environmental condition, including restoring habitat for biodiversity. However, barriers widespread implementation still exist, competition limited space, lack technical capacity, disengaged community. New approaches restoration urgently needed that suit small fragments space available, can deliver multiple reconnect people with overcome these challenges, ‘ecology cities’ perspective, combining horticultural, ecological social management restoration, needed. Significant opportunities exist ecologists zoologists engage practitioners community co-develop implement successfully achieve aim creating biodiverse environments.
