Forest conservation maximises açaí palm pollination services and yield in the Brazilian Amazon

Journal of Applied Ecology, Journal Year: 2023, Volume and Issue: 60(9), P. 1964 - 1976

Abstract Agricultural expansion is one of the main drivers global pollinator loss. Paradoxically, this occurs while agriculture becoming increasingly dependent on biotic pollination, raising concerns about food production. Integrated Crop Pollination (ICP), use both wild and managed pollinators in crop fields, can help conserve diversity ensuring effective pollination services for growers. However, given context‐dependent nature approach, there an urgent need to evaluate its application across different landscapes crops.

Pollinator diversity, pollination services, and conservation in agroecosystems: A mini‐review on the successes and challenges in China

Integrative Conservation, Journal Year: 2024, Volume and Issue: 3(2), P. 104 - 111

Published: May 8, 2024

Abstract Pollinators provide important pollination services for crops around the world. In China, numerous studies have been conducted on pollinators within agroecosystems, yet a comprehensive review of such research remains to be completed. This study discusses existing knowledge pollinator diversity in Chinese examines provision services, and identifies key achievements limitations. We propose series conservation management actions promote health ecosystem these agroecosystems: (1) long‐term monitoring populations, (2) designing agricultural landscapes that are conducive pollinators, (3) implementing microscale habitat modifications improve conditions pollinators.

Assessing Buffer Gradient Synergies: Comparing Objective and Subjective Evaluations of Urban Park Ecosystem Services in Century Park, Shanghai

Land, Journal Year: 2024, Volume and Issue: 13(11), P. 1848 - 1848

Published: Nov. 6, 2024

Urban parks provide essential ecosystem services (ESs) that enhance human wellbeing. However, discrepancies often arise between objective assessments of these and stakeholders’ subjective perceptions. This study addresses a research gap concerning the synergies tradeoffs evaluations perceptions key across various spatial scales. We investigated six in Century Park, Shanghai, seven buffer radii (8–100 m). Objective data were obtained from park view images (PVIs) analysis, while gathered through scoring survey 33 stakeholders. The finding is radius 35 m offers optimal synergy for most ESs, particularly pollution mediation, temperature regulation, cultural services. Professionals showed stronger alignment regulatory like mediation residents exhibited higher net primary production (NPP) beyond 75 radius. Notably, displayed nuanced differences, with professionals preferring simpler landscapes demonstrating varied aesthetic preferences. These findings emphasize importance integrating urban green space planning governance. By incorporating diverse stakeholders identifying zones, planners designers can effectively balance ESs experiences. approach ultimately fosters more sustainable wellbeing-centered environments.

Policy Brief: The role of Amazonian Indigenous Peoples in fighting the climate crisis

Published: Nov. 1, 2022

Indigenous territories (ITs) in the Amazon protect approximately 24.5 GtC aboveground, act as significant barriers to deforestation and forest degradation, serve an important buffer against climate change. Demarcated ITs have significantly less than unrecognized lands, demonstrating importance of demarcating both livelihoods cultures Amazon’s native peoples conserve its forests rivers.

The bee fauna (Hymenoptera, Apoidea) in Cerrado and Cerrado-Amazon Rainforest transition sites in Tocantins state, Northern Region of Brazil

Biota Neotropica, Journal Year: 2022, Volume and Issue: 22(3)

Published: Jan. 1, 2022

Abstract: Two sites located in Tocantins State, Brazil, were selected for the bee’s community survey. One of them was mostly covered by Cerrado vegetation and other one is Cerrado-Amazon Rainforest ecotone. Five expeditions performed each site throughout a 12-month period, between 2019 2020. The total 771 bee specimens collected distributed into four families. Apidae presented greatest species abundance richness, it followed Halictidae, Megachilidae Andrenidae, respectively. Trigona pallens (Fabricius) (Apidae) presenting both sites, totaled 118 specimens, which corresponded to 26.9% individuals belonging tribe Meliponini. In general, several with few many individuals. Bee collections using three different methodologies, among finds sampling based on entomological net method, allowed collecting largest number comparison used methods. Based frequency classes, only classified as very frequent (VF) abundant (VA) classes. Most constant (W) regions, there small dominant (D); moreover, more than 70% sampled considered accidental (Z). According present study, either or studied higher richness these biomes Brazil.

Products based on entomopathogenic fungi are extensively used to control insect pests. These biopesticides can result in lethal or sublethal effects non-target organisms. This study aimed evaluate the survival of Melipona scutellaris Latreille workers exposed commercial products Beauveria bassiana (IBCB 66), Metarhizium anisopliae 425), and Isaria fumosorosea (ESALQ 1296). Fifty foragers were B. at 8.25 x 106 conidia/mL, M. 1.1 107 I. 2.5 109 using three routes exposure (ingestion, contact with a surface, topical application). Kaplan-Meier curves estimated determine proportion surviving after each application biopesticides. Workers bassiana, anisopliae, presented rates 74%, 34%, 42%, respectively, 168 hours by ingestion. For via contaminated 64%, 70%, 78%; for application, 68%, 66%, 72% survived, respectively. The results highlight variability toxicity workers. Although all resulted mortality, bee varied depending route. Understanding effect fungi-based may facilitate development strategies (such as timing frequency spraying) reduce their impact bees.
