Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

Oikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Cotton facilitates long‐distance seed dispersal by functioning as nest material for birds

Oikos, EarlyView.
Cotton (Cossypium) fibres, which grow naturally in bolls around the seeds of cotton plants, have been used for centuries to produce fabric. The presumed natural function of cotton is that these lightweight and fluffy fibres may support wind dispersal of the seeds inside.
