Mapping the species richness and composition of tropical forests from remotely sensed data with neural networks [PDF]

open access: yes, 2006
The understanding and management of biodiversity is often limited by a lack of data. Remote sensing has considerable potential as a source of data on biodiversity at spatial and temporal scales appropriate for biodiversity management.

occumb: An R package for site occupancy modeling of eDNA metabarcoding data

open access: yesPopulation Ecology, EarlyView.
This study introduces a new R package, occumb, for the convenient application of site occupancy modeling using environmental DNA (eDNA) metabarcoding data. We outline a data analysis workflow, including data setup, model fitting, model assessment, and comparison of potential study settings based on model predictions, all of which can be performed using

The value of biodiversity [PDF]

open access: yesBrazilian Journal of Biology, 2008
In addition to its intrinsic value (nature working as it is; species are the product of a long history of continuing evolution by means of ecological processes, and so they have the right to continued existence), biodiversity also plays a fundamental role as ecosystem services in the maintenance of natural ecological processes.

Prototype Biodiversity Digital Twin: grassland biodiversity dynamics [PDF]

open access: yesResearch Ideas and Outcomes
European grassland management has often favoured high production through frequent mowing and heavy fertilisation over biodiversity conservation, which is typically supported by less intensive management.

Functional Biodiversity [PDF]

open access: yes, 2001
Modern conventional agriculture is characterized by monocultures. These are less productive in terms of biomass than natural plant communities, which are usually complex mixtures of species and varieties, and they also require more inputs.

Biodiversity, community structure and function of biofilms in stream ecosystems [PDF]

open access: yes, 2015
Multi-species, surface-attached biofilms often dominate microbial life in streams and rivers, where they contribute substantially to biogeochemical processes.

Multi‐Scaled Cellulosic Nanonetworks from Tunicates

open access: yesAdvanced Functional Materials, EarlyView.
Microbial and plant nanonetworks of cellulose have enabled a wide range of high‐performance yet sustainable materials. Herein, a third class of cellulosic nanonetworks is showcased by exploiting the only animal tissue‐producing cellulose nanofibers, i.e., ascidians. An ultrastructure including spherical cells and a microvasculature with diameters of 50–

Reforming society via biodiversity, biodiversity as a public policy Reforming society via biodiversity, biodiversity as a public policy [PDF]

open access: yesSciences, Eaux & Territoires, 2011
The French Ecology ministry looks back over several years of public policies for biodiversity conservation. The glass is only half full with mixed results in the field, but significant progress in public debates and some encouraging developments.

Covalent Organic Frameworks for Photocatalysis

open access: yesAdvanced Materials, EarlyView.
This review provides an overview of recent advances in covalent organic frameworks (COFs) for photocatalysis, focusing on sustainable energy applications like water splitting, hydrogen peroxide generation, and CO2 and N2 reduction. It discusses design principles, structure‐function relationships, challenges in COF photocatalysis, and strategies to ...
