Meta-analysis of multidecadal biodiversity trends in Europe

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: July 13, 2020

Abstract Local biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract change. We analyze 161 long-term biological series (15–91 years) collected across Europe, using a comprehensive dataset comprising ~6,200 marine, freshwater and terrestrial taxa. test whether (i) consistent among biogeoregions, realms taxonomic groups, (ii) changes in correlate with regional climate conditions. Our results reveal that of abundance, richness diversity differ demonstrating at scale often complex cannot easily generalized. However, we find increases abundance increasing temperature naturalness well clear spatial pattern community composition (i.e. temporal turnover) most biogeoregions Northern Eastern Europe.

Interpreting insect declines: seven challenges and a way forward

Insect Conservation and Diversity, Journal Year: 2020, Volume and Issue: 13(2), P. 103 - 114

Published: March 1, 2020

Abstract Many insect species are under threat from the anthropogenic drivers of global change. There have been numerous well‐documented examples population declines and extinctions in scientific literature, but recent weaker studies making extreme claims a crisis drawn widespread media coverage brought unprecedented public attention. This spotlight might be double‐edged sword if veracity alarmist decline statements do not stand up to close scrutiny. We identify seven key challenges drawing robust inference about declines: establishment historical baseline, representativeness site selection, robustness time series trend estimation, mitigation detection bias effects, ability account for potential artefacts density dependence, phenological shifts scale‐dependence extrapolation sample abundance population‐level inference. Insect fluctuations complex. Greater care is needed when evaluating evidence trends identifying those trends. present guidelines best‐practise approaches that avoid methodological errors, mitigate biases produce more analyses Despite many existing pitfalls, we forward‐looking prospectus future monitoring, highlighting opportunities creative exploitation baseline data, technological advances sampling novel computational approaches. Entomologists cannot tackle these alone, it only through collaboration with citizen scientists, other research scientists disciplines, data analysts next generation researchers will bridge gap between little bugs big data.

The Resilience of Indigenous Peoples to Environmental Change

One Earth, Journal Year: 2020, Volume and Issue: 2(6), P. 532 - 543

Published: June 1, 2020

Indigenous peoples globally have high exposure to environmental change and are often considered an "at-risk" population, although there is growing evidence of their resilience. In this Perspective, we examine the common factors affecting resilience by illustrating how interconnected roles place, agency, institutions, collective action, knowledge, learning help cope adapt change. Relationships with place particularly important in that they provide a foundation for belief systems, identity, livelihood practices underlie mechanisms through which experienced, understood, resisted, responded to. Many also face significant vulnerabilities, whereby dislocation due land dispossession, resettlement, landscape fragmentation has challenged persistence knowledge systems undermined compounded speed These vulnerabilities closely linked colonization, globalization, development patterns, underlying importance tackling these pervasive structural challenges.

The direct interactions between people and nature are critically important in many ways, with growing attention particularly on their impacts human health wellbeing (both positive negative), people's attitudes behaviour towards nature, the benefits hazards to wildlife. A evidence base is accelerating understanding of different forms that these human-nature take, novel analyses revealing importance opportunity orientation individual as key drivers interactions, methodological developments increasingly making apparent spatial, temporal socio-economic dynamics. Here, we provide a roadmap advances identify key, often interdisciplinary, research challenges remain be met. We identified several challenges, including need characterize through life course, determine comparable fashion how vary across much more diverse geographical, cultural contexts have been explored date, quantify relative contributions shaping interactions. robust effort, guided by focus such unanswered questions, has potential yield high-impact insights into fundamental contribute developing strategies for appropriate management.

Thresholds of freshwater biodiversity in response to riparian vegetation loss in the Neotropical region

Journal of Applied Ecology, Journal Year: 2020, Volume and Issue: 57(7), P. 1391 - 1402

Abstract Protecting riparian vegetation around streams is vital in reducing the detrimental effects of environmental change on freshwater ecosystems and maintaining aquatic biodiversity. Thus, identifying ecological thresholds useful for defining regulatory limits guiding management zones towards conservation biota. Using nationwide data fish invertebrates occurring small Brazilian streams, we estimated native loss which there are abrupt changes occurrence abundance bioindicators tested whether congruent responses among different biomes, biological groups buffer sizes. Mean cover varied widely sizes groups: ranging from 0.5% to 77.4% fish, 2.9% 37.0% 3.8% 43.2% a subset invertebrates. Confidence intervals were wide, but minimum values these lower smaller buffers (50 100 m) than larger ones (200 500 m), indicating that land use should be kept away streams. Also, occurred at percentage buffers, critically invertebrates: only 6.5% within 50‐m enough cross Synthesis applications . The high variability biodiversity suggests caution single width actions or policy definitions nationwide. most sensitive can used as early warning signals In practice, least wide reserves each side would more effective protect Brazil.

Published: Dec. 1, 2021

Global freshwater biodiversity is declining dramatically, and meeting the challenges of this crisis requires bold goals mobilisation substantial resources. While reasons are varied, investments in both research conservation lag far behind those terrestrial marine realms. Inspired by a global consultation, we identify 15 pressing priority needs, grouped into five areas, an effort to support informed stewardship biodiversity. The proposed agenda aims advance globally as critical step improving coordinated actions towards its sustainable management conservation.

Abstract The human relationship with nature is a topic that has been explored throughout history. More recently, the idea of connection to merged as an important transdisciplinary field study. Despite increased scholarly attention nature, notion disconnection from remains undertheorized and understudied. In this perspective article, we argue for more comprehensive understanding strengthen theories human‐nature relationships goes beyond individual considers social collective factors disconnection, including institutional, socio‐cultural power dimensions. Drawing on case insights, present ‘wheel disconnection’ illustrate how disconnections manifest across or societal meaning‐making processes, thereby problematizing existing research seeks create dualisms between positive negative impacts environment in isolation cultural political contexts.

The connection that individuals have with nature impacts their well-being and support for pro-nature policies. While it is generally believed the between humans decreasing, extent of this trend uncertain. Here, we present a global analysis temporal changes in people's psychological physical connections to nature. Using systematic review protocol, identified 71 articles consisting 100 case studies. Most these studies used cross-sectional, rather than longitudinal, approaches, which examine among people different ages. literature reviewed indicates there has been decline human over time. However, magnitude varied by geographic socio-economic settings, some showing an increasing trend. These findings suggest are opportunities limit reverse ongoing disconnection from where does occur.
