Functional Responses of Coccinella undecimpunctata and Chrysoperla carnea to their Aphid Prey under Semi-Field Conditions [PDF]

open access: yesJournal of Plant Protection and Pathology, 2020
Understanding the interactions between predator and prey is the basis for creating a strategy for the biocontrol of aphids. One of the most informative methods to understand these interactions is the functional response. In this study, the predation efficiency, of the second-instars of Coccinella undecimpunctata L.

Geographic variation in the habitat preference of a scarce predatory insect: evolutionary and conservation perspectives

open access: yesEcological Entomology, Volume 45, Issue 3, Page 386-395, June 2020., 2020
The 5‐spot ladybird is specialised in pioneer habitats close to water, but broadens its range to include non‐riverine pioneer habitats in north‐west continental Europe. (Micro)climatic factors (in this case humidity) appear to be important in forming the habitat preferences of this and probably other predators that are not constrained by where their ...

Thinking like a naturalist: Enhancing computer vision of citizen science images by harnessing contextual data

open access: yesMethods in Ecology and Evolution, Volume 11, Issue 2, Page 303-315, February 2020., 2020
Abstract The accurate identification of species in images submitted by citizen scientists is currently a bottleneck for many data uses. Machine learning tools offer the potential to provide rapid, objective and scalable species identification for the benefit of many aspects of ecological science.
