Microbial communities are found throughout the biosphere, from human guts to glaciers, soil activated sludge. Understanding statistical properties of such diverse can pave way elucidate common mechanisms ...Multiple ecological forces act together shape composition microbial communities. Phyloecology approaches—which combine phylogenetic relationships between species with community ecology—have potential disentangle but often ...

Mapping the irrecoverable carbon in Earth’s ecosystems

Nature Sustainability, Год журнала: 2021, Номер 5(1), С. 37 - 46

Опубликована: Ноя. 18, 2021

Abstract Avoiding catastrophic climate change requires rapid decarbonization and improved ecosystem stewardship at a planetary scale. The carbon released through the burning of fossil fuels would take millennia to regenerate on Earth. Though timeframe recovery for ecosystems such as peatlands, mangroves old-growth forests is shorter (centuries), this still exceeds time we have remaining avoid worst impacts global warming. There are some natural places that cannot afford lose due their irreplaceable reserves. Here map ‘irrecoverable carbon’ globally identify remains within human purview manage and, if lost, could not be recovered by mid-century, when need reach net-zero emissions impacts. Since 2010, agriculture, logging wildfire caused least 4.0 Gt irrecoverable carbon. world’s 139.1 ± 443.6 faces risks from land-use conversion change. These can reduced proactive protection adaptive management. Currently, 23.0% protected areas 33.6% managed Indigenous peoples local communities. Half Earth’s concentrated just 3.3% its land, highlighting opportunities targeted efforts increase security.

The planetary role of seagrass conservation

Science, Год журнала: 2022, Номер 377(6606), С. 609 - 613

Seagrasses are remarkable plants that have adapted to live in a marine environment. They form extensive meadows found globally bioengineer their local environments and preserve the coastal seascape. With increasing realization of planetary emergency we face, there is growing interest using seagrasses as nature-based solution for greenhouse gas mitigation. However, seagrass sensitivity stressors acute, many places, risk loss degradation persists. If ecological state remains compromised, then ability contribute solutions climate biodiversity crisis doubt. We examine major role play how rethinking conservation critical understanding part fighting our emergency.

Addressing chemical pollution in biodiversity research

Global Change Biology, Год журнала: 2023, Номер 29(12), С. 3240 - 3255

Опубликована: Март 21, 2023

Abstract Climate change, biodiversity loss, and chemical pollution are planetary‐scale emergencies requiring urgent mitigation actions. As these “triple crises” deeply interlinked, they need to be tackled in an integrative manner. However, while climate change often studied together, as a global factor contributing worldwide loss has received much less attention research so far. Here, we review evidence showing that the multifaceted effects of anthropogenic chemicals environment posing growing threat ecosystems. Therefore, failure account for may significantly undermine success protection efforts. We argue progress understanding counteracting negative impact on requires collective efforts scientists from different disciplines, including but not limited ecology, ecotoxicology, environmental chemistry. Importantly, recent developments fields have now enabled comprehensive studies could efficiently address manifold interactions between Based their experience with intricate biodiversity, ecologists well equipped embrace additional challenge complexity through interdisciplinary collaborations. This offers unique opportunity jointly advance seminal frontier ecology facilitate development innovative solutions protection.

Digitalization and the Anthropocene

Annual Review of Environment and Resources, Год журнала: 2022, Номер 47(1), С. 479 - 509

Опубликована: Сен. 3, 2022

Great claims have been made about the benefits of dematerialization in a digital service economy. However, digitalization has historically increased environmental impacts at local and planetary scales, affecting labor markets, resource use, governance, power relationships. Here we study past, present, future through lens three interdependent elements Anthropocene: ( a) boundaries stability, b) equity within between countries, c) human agency mediated via i) increasing efficiency, ii) accelerating consumption scale effects, iii) expanding political economic control, iv) deteriorating social cohesion. While direct matter, indirect systemic effects are more profoundly reshaping relationship humans, technosphere planet. We develop scenarios: instability, green but inhumane, deliberate for good. conclude with identifying leverage points that shift human–digital–Earth interactions toward sustainability.

Transnational Corporations, Biosphere Stewardship, and Sustainable Futures

Annual Review of Environment and Resources, Год журнала: 2022, Номер 47(1), С. 609 - 635

Опубликована: Март 9, 2022

Corporations are perceived as increasingly powerful and critically important to ensuring that irreversible climatological or ecological tipping points on Earth not crossed. Environmental impacts of corporate activities include pollution soils, freshwater the ocean, depletion ecosystems species, unsustainable use resources, changes air quality, alteration global climate. Negative social unacceptable working conditions, erosion traditional practices, increased inequalities. Multiple formal informal mechanisms have been developed, innovative examples biosphere stewardship resulted in progress. However, crisis underscores such efforts insufficient transformative change is urgently needed. We provide suggestions for aligning with argue requires more ambitious approaches taken by corporations, combined new formalized public governance governments.
