Pinguicula brendae (Lentibulariaceae) sp. nov., a carnivorous plant from a tropical montane cloud forest in Hidalgo, Mexico

open access: yesNordic Journal of Botany, EarlyView.
A new species of Lentibulariaceae, Pinguicula brendae Rodríguez‐Ramírez, H.Shimai & A.R. Andrés‐Hernández, is described based on its unique morphological characteristics. This species is restricted to limestone rock walls in the San Bartolo Tutotepec municipality, central‐eastern Hidalgo, Mexico, where it inhabits a single locality on vertical, north ...

Genetic analysis of the rare forest bryophyte Dicranum viride in the boreo‐nemoral zone near the northern distribution range limit

open access: yesNordic Journal of Botany, EarlyView.
Bryophytes are important forest ecosystem elements, being an integral part of biodiversity. Genetic studies contribute to bryophyte population ecology by helping to understand species historical distribution patterns and genetic diversity at different scales.

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

open access: yesNear 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.

Floral resource‐mediated multilayer networks: structure and pollinators' roles

open access: yesOikos, EarlyView.
Resource availability shapes interactions among free‐living species, particularly in plant–pollinator mutualisms, where the composition of floral resource types influences pollinator foraging. Bees, known for utilizing a broad array of floral resources, play a crucial role in these dynamics. However, how the structure of interaction networks vary among
