The role of rivers in the origin and future of Amazonian biodiversity

Published: Jan. 15, 2025

The rich biodiversity of Amazonia is shaped geographically and ecologically by its rivers their cycles seasonal flooding. Anthropogenic effects, such as deforestation, infrastructure development extreme climatic events, threaten the ecological processes sustaining Amazonian ecosystems. In this Review, we explore coupled evolution associated with terrestrial seasonally flooded environments, integrating geological, climatic, genetic evidence. fluvial environments are highly heterogeneous, drainage system historically dynamic continually evolving; a result, discharge, sediment load strength barriers to biotic dispersal has changed through time.

Scientific contributions and lessons learned from 30 years of ecological monitoring of the Bylot Island tundra ecosystem

Frontiers in Ecology and Evolution, Journal Year: 2024, Volume and Issue: 12

The Arctic tundra has a relatively low biodiversity but species living there have unique adaptations and are exposed to unprecedented rates of climate warming. Monitoring changes in identifying the driving forces is thus pressing issue. Bylot Island Canadian one longest most comprehensive monitoring programs food web, spanning four decades. We provide historical overview ecological studies on Island, summarize their key scientific contributions, show impacts, present ingredients for success program main challenges encountered.

Linking network ecology and ecosystem services to benefit people

People and Nature, Journal Year: 2024, Volume and Issue: 6(3), P. 1048 - 1059

Published: March 22, 2024

Abstract Ecosystems are rapidly degraded by anthropogenic pressures, affecting the provision of ecosystem services. Therefore, it is increasingly important that we can quantify and manage services to maintain human well‐being. Many underpinned functions processes driven interspecific ecological interactions. Humans then benefit from through socio‐ecological interaction network approaches provide a unique understanding service flows. In this paper, assess current interface between ecology services, before exploring how work linking these two fields could be enhanced. We emphasise value explore methods improve assessment management Within this, highlight role local indigenous knowledge in operationalising useful context.

O Pantanal é um bioma dependente do fogo com regime natural de inundação, criando uma região características peculiares que moldaram seu meio ambiente, sua biodiversidade, seus habitantes e a maneira como eles vivem: intimamente ligada à dinâmica local. tem sido utilizado no ferramenta manejo paisagens há milhares anos pela população indígena e, medida em foi sendo ocupada por outros grupos, o conhecimento passado para os novos habitantes, fazendeiros. Essas práticas estão incorporadas nas tradições modo vida local, chegando ao ponto se tornarem aspecto importante patrimônio cultural Pantanal. Entretanto, mudanças culturais na ocupação uso da terra nos últimos 50-60 têm gerado impactos significativos ameaçam sustentabilidade futuro bioma.

The importance of worldwide linguistic and cultural diversity for climate change resilience

Abstract Local minority languages and dialects, through the local knowledge expertise associated with them, can play major roles in analysing climate change biodiversity loss, facilitating community awareness of environmental crises setting up locally‐adapted resilience sustainability strategies. While situation contribution Indigenous Tribal Peoples are emblematic importance, issue relationships between cultural linguistic diversity protection does not solely concern peripheral highly‐specialized communities specific ecosystems Global South, but constitutes a worldwide challenge, throughout all countries, whatever their geographical location, economical development, or political status. Environmental emergency should therefore raise international on need to promote survival development dialects take into account creativity relation dynamics environments.

Fungi are arguably the most diverse eukaryotic kingdom of organisms in terms number estimated species, trophic and life history strategies, their functions ecosystems. However, our knowledge fungi is limited due to a distributional bias; vast majority available data on have been compiled from non-tropical regions. Far less known about tropical regions, with bulk these being temporally surveys for fungal species diversity. Long-term studies (LTS), or repeated sampling same region over extended periods, necessary fully capture extent diversity region, but LTS regions almost non-existent. In this paper, we discuss contributions alpha diversity, ecological functional biogeography, hypothesis testing, conservation-with an emphasis ongoing Pakaraima Mountains Guyana. We show how refine understanding Fungi. also that public repositories such as NCBI, IUCN, iNaturalist contain information compared fungi, discrepancies more pronounced than plants animals.

Societal Impact Statement Protecting diversity is critical to maintaining functional and adaptive ecosystems. However, research groups that explore these relationships tend lack themselves. To address the challenges of our changing world, it crucial consider a wide range perspectives knowledge. We propose just as greater in ecosystems relates variety functions and, consequently, enhances resilience, stability, efficiency, comparable within teams results broader spectrum creative endeavors. Thus, important re‐evaluate scientific communities' openness toward meet diverse problems world. Summary Ecosystems face multiple threats, jeopardizing natural human well‐being. Biodiversity loss can increase ecosystem vulnerability global change, risking abrupt irreversible changes. biodiversity prevent from crossing tipping points, preserving their which sustain life on planet. In addressing challenges, society demands creativity, innovation, perspectives. Yet, societal structures often neglect full voices experiences, limiting problem‐solving. Understanding how with demographics may stimulate solutions change help. this context, we emphasize examples plant ecology, where advantages are well recognized, draw an analogy features innovation teams. ecosystems, maximize productivity function but also serve protective “insurance” against disruptions. Similarly, time multifaceted environmental changes, play analogous role, resembling Diverse not only bring complementary strengths, fostering problem‐solving by embracing various perspectives, drive integrating topics (e.g., taxa, conservation priorities). These human‐centered dynamics congruent mechanisms promoting all ultimately provide counterbalancing effect change.

Our approach acknowledged social dynamics perpetuating colonial hierarchies. We framed genetic empower knowledge and communities' history identities. A fundamental step our strategy has been sharing before publishing paper, which allowed us incorporate community perspectives. faced challenge of translating concepts like admixture, emphasizing distinction between identity biology. To reach broad diverse audience, disseminated single members, cultural representatives, high schools, highlighting importance region European contact. facilitate dissemination, prepared didactic material report Spanish written non-specialized language, targeting wider Latin American readership.
