The collective discussions reflect a nuanced understanding of the article’s findings, with comments referencing specific studies, debates over methodological biases, and regional differences, illustrating active engagement and interest. Words like 'alarming,' 'nuanced,' and references to meta-analyses emphasize both concern and the complexity of insect population trends.
AgreementModerate agreement
Most discussions support the findings of the meta-analysis, acknowledging the decline of terrestrial insects and the increase in freshwater insects, with some skepticism about the severity or causes.
InterestHigh interest
Participants display high interest, referencing specific data, regional differences, and methodological debates, showing engagement with complex ecological issues.
EngagementModerate engagement
Many posts delve into methodological details, regional studies, and implications, indicating active engagement beyond surface-level commentary.
ImpactModerate impact
While the discussions highlight important ecological trends, they suggest a moderate perceived impact, mainly emphasizing the importance of understanding insect dynamics rather than immediate policy changes.
Abstract in brief
A meta-analysis of 166 long-term insect studies across 1676 sites found that terrestrial insects are declining in abundance by about 9% per decade, while freshwater insects are increasing by approximately 11% per decade, with notable regional differences mainly in North America and Europe.
There was significant variation in insect trends even among nearby sites, and some potential drivers like land use changes and protected areas showed weaker associations with these trends.
Overall, the study offers a more detailed and complex understanding of how insect populations are changing across different environments and regions, challenging simpler narratives of widespread declines.
Eén van de meest zorgwekkende trends is de achteruitgang van de landinsecten. Van Klink et al. (2020) spreken van een achteruitgang met -1% per jaar, gebaseerd op een analyse van 166 studies. Weliswaar geen achteruitgang bij zoetwaterbeestjes. 16/ https://t.co/E3g7Gjh08y https://t.co/3xpODMDakN

"Nuanced changes in insect abundance":
https://t.co/6PHYU8ZDNA https://t.co/Ke0Eaykub3
Estamos perdiendo cerca de un 9% de los insectos terrestres por cada década que pasa. Curiosamente, los insectos de agua dulce están aumentando, pero son una porción muy pequeña del total (metaanálisis, 166 estudios) https://t.co/90qQu5irEB (blog, abajo) https://t.co/uSjxTRS5KT
however, what REALLY offends me is the alarming population decline of terrestrial arthropods that seems to be driven by human land use and lack of environmental protections

@DavidCormand 2ème problème : la forte hétérogénéité des conclusions due aux difficultés méthodologiques permet de faire jouer le cherry picking du plus anxiogène au plus rassurant.
Par exemple la plus grosse (et récente) meta-analyse est bien moins alarmiste. 3/3
https://t.co/AzgwuEuU0r
@GeWoessner Dans Science on a une meta-analyse plus récente qui estime à 9% par décennies le déclin des insectes terrestres. Par contre en milieu aquatique les populations augmenteraient de 11%.
Mais là aussi des biais méthodologiques ont été mis en évidence.
https://t.co/AzgwuEumaT
@GeWoessner Ou cette méta-analyse qui constate bien un déclin des insectes terrestres, mais une hausse des espèces aquatiques. Une correction arrive aussi à la conclusion que les preuves du déclin sont faibles en Europe.

@gerardgovers Dat ga ik niet in twijfel trekken, maar uit Europa liggen een serie (veelal lokalere) studies voor die drastische achteruitgang van o.a. loopkevers, zweefvliegen, vlinders en spinnen aantonen. Misschien ook deze metastudie ernaast leggen: https://t.co/E3g7Gjh08y

@no_username_yet @MaxCRoser (a) I'm not angry.
(b) I pointed out the increased life expectancy, which is observable data. You have asserted negative effects but shown nothing specific.

@MrNeilerua @emma_ducros L'abandon des néonicotinoïdes n'a montré nulle part une inversion de tendance.
D'autre part personne n'est en mesure de chiffrer le déclin des insectes ni ses causes.
Même la plus grosse meta analyse sur le sujet ne fait pas consensus ⤵️

@BrianRoemmele 1/ Now that you mention it, I can't recall any offered evidence that total insect population is substantially decreasing. When I google for papers, I find stuff like this, suggesting lower loss rates and local drivers.
https://t.co/xE0odgFGYv
Difficile d'avoir un portrait global de la situation des insectes. Certaines études semblent indiquer de forte baisse alors que d'autres non. Même si la situation semble parfois inquiétante, le mot hécatombe n’est pas approprié.

2. We're sure
Meta-analysis by @PunksInScience confirmed global declines, albeit not same rates and not for freshwater insects.
BUT: Major data gaps for subtropical and tropical regions where a) most insects resides and b) rapid land-use change occur.

Just this year van Klink etal (DOI: 10.1126/science.aax9931) found global declines in terrestrial insect populations.
Apart from their indirect services, insects are still inspiring biomimetic technology for humans, underscoring their importance. #ironclad

The widely reported “insect apocalypse” is more nuanced than work suggests, according to new @idiv study, which reports findings of meta-analysis using data from 166 surveys across 1,676 sites worldwide. Global insect trends reflect both decline + growth. https://t.co/zGLJuzB5Re https://t.co/eJ6hO82zOs
