Insect Declines in the Anthropocene

Annual Review of Entomology, Journal Year: 2019, Volume and Issue: 65(1), P. 457 - 480

Published: Oct. 14, 2019

Insect declines are being reported worldwide for flying, ground, and aquatic lineages. Most reports come from western northern Europe, where the insect fauna is well-studied there considerable demographic data many taxonomically disparate Additional cases of faunal losses have been noted Asia, North America, Arctic, Neotropics, elsewhere. While this review addresses both species loss population declines, its emphasis on latter. Declines abundant can be especially worrisome, given that they anchor trophic interactions shoulder essential ecosystem services their respective communities. A factors believed to responsible observed collapses those perceived threatening insects form core treatment. In addition widely recognized threats biodiversity, e.g., habitat destruction, agricultural intensification (including pesticide use), climate change, invasive species, assessment highlights a few less commonly considered such as atmospheric nitrification burning fossil fuels effects droughts changing precipitation patterns. Because geographic extent magnitude largely unknown, an urgent need monitoring efforts, across ecological gradients, which will help identify important causal in declines. This also considers status vertebrate insectivores, reporting bias, challenges inherent collecting interpreting data, increasing abundance.

Assessing the environmental impacts of invasive alien plants: a review of assessment approaches

NeoBiota, Journal Year: 2019, Volume and Issue: 43, P. 69 - 99

Published: March 15, 2019

Assessing the impacts of alien plant species is a major task in invasion science and vitally important for supporting invasion-related policies. Since 1993, range assessment approaches have been developed to support decisions on introduction or management species. Here we review extent which assessments (27 approaches) appraised following: (i) different types environmental impacts, (ii) context dependence (iii) prospects successful management, (iv) transparency methods criteria, underlying values terminology. While nearly all covered effects, changes genetic diversity incorporation relevant impact parameters were less likely be included. Many considered by incorporating information about actual potential However, only few went further identified resources conservation concern might affected specific Only some acknowledged distinguishing negative from positive considering value resources. Several directly addressed feasibility whereas factors such as availability suitable rarely considered. Finally, disclosed, definitions value-laden controversial terms often lacking. We conclude that despite progress assessing manifold facets opportunities remain developing approaches. These can improve results their acceptance

A “plan bee” for cities: Pollinator diversity and plant-pollinator interactions in urban green spaces

PLoS ONE, Journal Year: 2020, Volume and Issue: 15(7), P. e0235492 - e0235492

Green infrastructure in cities is considered to serve as a refuge for insect pollinators, especially the light of an ongoing global decline insects agricultural landscapes. The design and maintenance urban green spaces key components play crucial role case nesting opportunities foraging insects.

Impacts of invasive biota in forest ecosystems in an aboveground–belowground context

Biological Invasions, Journal Year: 2017, Volume and Issue: 19(11), P. 3301 - 3316

Published: Feb. 8, 2017

Forest ecosystems world-wide are being subjected to invasion by organisms representing all domains of life. Here we use a combined aboveground-belowground approach provide conceptual framework for assessing how forests respond biological invasions. We first address mechanisms which invasive plants and aboveground belowground consumers impact on forests, highlight that although have growing understanding the determinants effects plants, yet move from series iconic case studies development general principles. also biota in context drivers invasion, co-invasion invasional meltdown, issue simultaneous species gains losses, forest restoration recovery post-invasion. then areas would benefit further work, particularly regarding underlying mechanisms, context-dependency invader effects, linkages between causes consequences invasion. In concluding, emphasize invaders potential large-scale long-term impacts processes, consideration these an will enable better prediction future responses their management as well efforts.

Emerging Urban Forests: Opportunities for Promoting the Wild Side of the Urban Green Infrastructure

Sustainability, Journal Year: 2019, Volume and Issue: 11(22), P. 6318 - 6318

Published: Nov. 11, 2019

Many cities aim to increase urban forest cover benefit residents through the provision of ecosystem services and promote biodiversity. As a complement traditional plantings, we address opportunities associated with “emerging forests” (i.e., spontaneously developing forests in cities) for biodiversity conservation. We quantified area successional analyzed species richness native alien plants invertebrates (carabid beetles, spiders) emerging dominated by or trees, including Robinia pseudoacacia, Acer platanoides, Betula pendula. Emerging were revealed as shared habitats species. Native was not profoundly affected (co-)dominance canopy. Instead, plant richnesses positively related. Numbers endangered did differ between native- alien-dominated patches. Patterns tree regeneration indicate different trajectories novel types. conclude that these (i) provide species, some (ii) allow city dwellers experience wild nature, (iii) support arguments adapting dynamic environments. Integrating into green infrastructure is promising pathway sustainable can restoration greening approaches.

Dual threat of tidal flat loss and invasive Spartina alterniflora endanger important shorebird habitat in coastal mainland China

Journal of Environmental Management, Journal Year: 2020, Volume and Issue: 278, P. 111549 - 111549

Published: Nov. 28, 2020

China's coastal wetlands are critically important to shorebirds. Substantial loss of tidal flats, shorebirds' primary foraging grounds, has occurred from land claim and other processes, is driving population declines in multiple species. Smooth cordgrass Spartina alterniflora was intentionally introduced the coast China 1979 promote conversion flats into dry since spread rapidly. The occurrence S. reduces availability roosting habitat for shorebirds, may be particularly detrimental places that have experienced flat loss. However, extent which encroaching upon shorebird throughout mainland China, its intersection with loss, not been quantified. Here, we i) estimate change spatial between 2000 2015 where internationally numbers shorebirds recorded; ii) map coverage at same set sites; and, iii) investigate these two threats intersect. Our analysis remote sensing data indicated a 15% net area across all sites, including 39 53 individual sites (74%). 28 (53%) 2015, 22 (79%) also had 2015. Combined pressures invasion were most severe eastern China.
