Abstract: Insects have diversified through more than 450 million y of Earth’s changeable climate, yet rapidly shifting patterns of temperature and precipitation now pose novel challenges as they combine with decades of other anthropogenic stressors including the conversion and degradation of land. Here, we consider how insects are responding to recent climate change while summarizing the literature on long-term monitoring of insect populations in the context of climatic fluctuations. Results to date suggest that climate… Show more

“…Our findings seem to contradict the common finding of declining insect richness with time (e.g., Hallmann et al, 2021;Homburg et al, 2019;Powney et al, 2019). For both overall diversity patterns (Hallmann et al, 2017;Seibold et al, 2019) and for different insect taxa, declining patterns are common, also during the 8 years we covered (Habel et al, 2019;Halsch et al, 2021;Janousek et al, 2023).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…That role involved a lag, in that elevated summer temperatures 1 year were associated with reduced insect abundance the following year (Figures 1 and 2). Other than the lag, this finding is consistent with another reporting rising temperature minima as a driver of declines in montane butterflies (Halsch et al, 2021). Future studies would benefit from classification of the insects to at least the order or family level to better understand any taxonomic concentrations of these declines.…”

“…Our findings reveal a complex interplay between climate variables and moth population dynamics across southeastern Sweden. The consistently positive relationship between temperature and population growth rates across all study sites aligns with previous observations in the region (Betzholtz et al, 2023a) and underscores temperature's pivotal role in driving moth population dynamics (Halsch et al, 2021; Harvey et al, 2023). This temperature sensitivity likely reflects moths' ectothermic nature and ability to capitalize on warmer conditions for increased metabolic activity, reproductive output and survival (Hahn & Denlinger, 2011).…”
