Temporal community change in stream ecosystems varies by assemblage across US climates
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Ecosystem properties are temporally dynamic. Temporal variability has been shown to decrease with increasing levels of biological organization (i.e. from population to community and ecosystem levels).

Driver-pressure-impact and response-recovery chains in European rivers: observed and predicted effects on BQEs [PDF]
, 2011 The report presented in the following is part of the outcome of WISER’s river Workpackage WP5.1 and as such part of the module on aquatic ecosystem management and restoration. The ultimate goal of WP5.1 is to provide guidance on best practice restoration

Extracting Additional Information From Biotic Index Samples [PDF]
, 2017 Macroinvertebrates were collected from a small midwestern stream over a 3-year period as part of a non-point source pollution study. Temporal and spatial variability in standard biotic index values (BIs) were computed and compared with variability ...

Effects of temperature and browning on the functional response of a freshwater top predator
Journal of Animal Ecology, EarlyView.This study explores for the first time how temperature and browning affect the functional response of a freshwater piscivore, the northern pike. The authors find surprisingly weak effects of browning, challenging visual foraging theory. Pike displayed a rare dome‐shaped functional response in cold clear water, potentially driven by seasonal changes in ...

Agricultural and Forest Entomology, EarlyView.We assessed the effect of the type of soil texture (loamy sand and sandy loam) and its physical properties on dung beetle species assemblages in a pastureland region of the Brazilian Cerrado. We found a reduction in the total and paracoprid beetle abundances in loamy sand soil. Furthermore, the increase of soil compaction negatively affected the entire

Entomologia Experimentalis et Applicata, EarlyView.Gut content analysis using DNA metabarcoding has improved understanding of predator–prey interactions involving spiders. We tested how starvation before feeding, time since feeding, spider size, and the presence of egg sacs or spiderlings affect prey DNA detection in Lycosidae.
