Taxonomic and functional patterns of arthropod succession after glacier retreat in the Dolomite Alps

Insect Conservation and Diversity, EarlyView.
Arthropod succession after glacier retreat varied among species and forelands in the Dolomites Alps, with community composition shaped by glacier identity, time since deglaciation and local environmental conditions. Functional composition shifted from small, highly dispersive pioneer species to larger, less dispersive taxa, reflecting increasing ...

Homogenization of two fluid flow in porous media

, 2015
The macroscopic behavior of air and water in porous media is often approximated using Richards’ equation for the fluid saturation and pressure. This equation is parametrized by the hydraulic conductivity and water release curve.

Mapping wild bee diversity and flower use for an effective conservation of the Doñana biodiversity hotspot

Insect Conservation and Diversity, EarlyView.
We compiled the first checklist of wild bees in Doñana Protected Area, documenting 385 species, including three vulnerable and one endangered species listed in the Red List. Bee species exhibit diverse floral preferences, highlighting the need to incorporate plant–pollinator interactions and the role of plants in conservation and management strategies ...

Manipulate Vibration Propagation by Anisotropic Honeycomb Structure

MATEC Web of Conferences, 2018
As a new type of acoustic metamaterial, the pentamode material has extensive application prospect in controlling acoustic wave propagation because of its fluid properties.

Protection status and environmental gradients shape butterfly assemblages in an East African tropical ecosystem

Insect Conservation and Diversity, EarlyView.
Observed butterfly richness was highest in moderately protected areas. During the dry season, vegetation productivity increased butterfly richness while human population density reduced it. Moderately protected areas supported high butterfly abundance and a high proportion of host‐specialist species.

Insights into diet and niche separation in the context of prey availability between two sympatric whiprays in a tropical intertidal estuary

Journal of Fish Biology, EarlyView.
Abstract Increasing evidence supports associations between various elasmobranch species and estuarine habitats, particularly during early life stages. However, with substantial knowledge gaps surrounding spatial habitat use and trophic ecology of estuary‐associated species in Australia, we cannot reliably assess the functional importance of these areas

Siliceous sponges or seawater as a silicon source? Tracing silicon burial pathways of the Upper Cretaceous opal‐CT deposits using δ30Si and δ7Li

Sedimentology, EarlyView.
ABSTRACT Classical models of formation of sedimentary siliceous rocks (flint, chert, opoka) commonly assume that the Cretaceous marine silicon (Si) cycle was primarily biologically controlled, broadly analogous to the modern ocean. In this framework, siliceous sponges are regarded as the principal source of dissolved silica (dSi) to sediment porewaters,

Asymptotic study of a nonlinear elliptic boundary Steklov problem on a nanostructure

Demonstratio Mathematica
The present study is related to the existence and the asymptotic behavior of the solution of a nonlinear elliptic Steklov problem imposed on a nanostructure depending on the thickness parameter ε\varepsilon (nano-scale), distributed on the boundary of ...
