Valuing the economic impacts of seed dispersal loss on voluntary carbon markets

Ecosystem Services, Journal Year: 2021, Volume and Issue: 52, P. 101362 - 101362

Seed dispersal is an ecosystem service strongly affected by the loss of mutualist dispersers, with economic consequences in terms carbon sequestration and climate change mitigation policies. Especially, large frugivores are important contributors to because they main disperser large-seeded trees, which store a high amount carbon. The effect seed dispersers defaunation on particularly significant tropical forests, where disperse 70–94% woody plant species ∼59% world's forest above ground stored. However, impacts services, such as sequestration, poorly valued. Here, we simulate effects three (Brachyteles arachnoides, Alouatta guariba, Pipile jacutinga) recruitment hardwood tree its impact markets. We found that combined would reduce standing 2.5%. also affects predator communities, influences contribution frugivores. By adding predators, reduction rise 3.5%. In summary, potential services provided our target ranges from US$3.94 ha−1 year−1 US$15.42 year−1. highlight importance conserving communities guarantee long-term viability sequestration. argue knowledge should be included policies encourage animal conservation restoration.

Activity patterns of domestic dogs and native terrestrial mammals in the Tapacurá Ecological Station, Brazil

Mammalogy Notes, Journal Year: 2024, Volume and Issue: 10(1), P. 359 - 359

Domestic dogs are a threat to biodiversity. We evaluated the activity patterns of domestic and terrestrial mammals in patch Atlantic forest northeastern Brazil. expected native change their temporal pattern presence dogs. installed 16 camera traps 2019 (January-March) cameras 2021 (February-April), with total effort 640 trap days. classified species as diurnal, cathemeral, nocturnal crepuscular. found 274 records 11 mammal overlapping between mammals. Coatis agoutis were strictly diurnal both years, while presented catemanal 2021. Aguties uniform pattern, but coatis did not. Although our findings suggest limited influence on mammals, vaccination or sterilization programs should be implemented avoid an increase negative impact fauna.

Ground‐dwelling mammal and bird diversity in the southern Annamites: Exploring complex habitat associations and the ghost of past hunting pressure

Conservation Science and Practice, Journal Year: 2024, Volume and Issue: 6(4)

Published: March 4, 2024

Abstract The Langbian Plateau, a biodiversity hotspot in the southern Annamites of Viet Nam, has undergone extensive hunting pressure. However, limited information on effects overexploitation current status and community composition wildlife hinders effective conservation efforts, including implementation targeted patrols to reduce snaring. In this study, we conducted camera‐trapping survey across consisting broadleaf evergreen coniferous habitat mosaic. We recorded 46 ground‐dwelling mammals birds, several threatened Annamite endemics. Using multi‐species Royle‐Nichols model landscape covariates, found higher richness forest located more remote less rugged areas. then used species responses covariates predict distribution identify high‐priority areas for conservation. Furthermore, constructed diversity profiles that indicated compared forest. Finally, dissimilarity index assess level defaunation, revealing 16% had been lost, with levels defaunation larger‐sized species. Our findings provide insights into status, distribution, occurrence mammal bird communities can help stakeholders design strategies protect existing populations.

Dispersal‐related plant traits are associated with range size in the Atlantic Forest

Diversity and Distributions, Journal Year: 2024, Volume and Issue: 30(7)

Published: May 28, 2024

Abstract Aim The efficiency of animal‐mediated seed dispersal is threatened by the decline animal populations, especially in tropical forests. We hypothesise that large‐seeded plants with tend to have limited geographic ranges and face an increased risk extinction due potential large‐bodied fruit‐eating seed‐dispersing animals (frugivores). Location Atlantic Forest, Brazil, South America. Taxon Angiosperms. Methods First, we collected dispersal‐related traits (dispersal syndrome, fruit size, size), growth form (tree, climber, other) preferred vegetation type (open closed) data for 1052 Forest plant species. Next, integrated these occurrence records, assessments, phylogenetic trees. Finally, performed generalised least squares regressions test direct interactive effects on geographical range size. Results Large‐seeded species had smaller sizes than small‐seeded species, but only dispersal, not those dispersed abiotic mechanisms. However, overall dispersal. Furthermore, found restricted forests occurring open or mixed vegetation. at 29% flora extinction, this was related syndromes. Main Conclusions may be suffering from limitation, potentially past ongoing defaunation frugivores, leading small sizes. Other factors, such as deforestation fragmentation, will probably modulate ultimately extinction. Our study sheds light relationship between traits, mutualistic interactions, distribution are key functioning

Priority areas and implementation of ecological corridor through forest restoration to safeguard biodiversity

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: July 15, 2024

Ecological Corridors (ECs) are proposed as cost-effective solutions to improve ecological connectivity in fragmented landscapes. Planning the implementation of ECs must take into account landscape features they affect viability endeavor and associated costs. A novel set geoprocessing tools were used analyze i) viability; ii) cost-effectiveness; iii) determine priority targets for establishment a highly region Atlantic Forest. Landscape features, land use cover, Enhanced Vegetation Index data obtained from remote sensing. Composition configuration metrics estimated by geostatistical methods. Study area was represented 35,344 forest fragments, which 94% composed fragments smaller ha 10 hectares size, leading characterized low connectivity. We identified 13 protection propose five corridors. These connect six with total 283.93 restore, on an cost nearly US$550.000,00. Conserving biodiversity one most threatened tropical rainforest regions could be promoted at modest costs, through key their reconnection landscape.
