Climate constrains the evolutionary history and biodiversity of crocodylians [PDF]

open access: yes, 2015
The fossil record of crocodylians and their relatives (pseudosuchians) reveals a rich evolutionary history, prompting questions about causes of long-term decline to their present-day low biodiversity.

Biodiversity As An Ecological Safety Condition. The European Dimension [PDF]

open access: yes, 2015
The main purpose of the paper is to indicate the theoretical bases of biodiversity protection from the perspective of the natural and economic sciences, and to describe the diversity of biodiversity protection levels in the EU states.

Conservation-Status Gaps for Marine Top-Fished Commercial Species

open access: yesFishes, 2021
Biodiversity loss is a global problem, accelerated by human-induced pressures. In the marine realm, one of the major threats to species conservation, together with climate change, is overfishing.

Automated pre-processing strategies for species occurrence data used in biodiversity modelling [PDF]

open access: yes, 2010
To construct Biodiversity richness maps from Environmental Niche Models (ENMs) of thousands of species is time consuming. A separate species occurrence data pre-processing phase enables the experimenter to control test AUC score variance due to species ...

A situational ethics and harmonization challenges in the case of EU biodiversity data governance

open access: yesInternational Journal of Digital Earth
The article discusses challenges in harmonizing biodiversity data by considering situational ethics in the valuation of data practices. Data harmonization involves technical processes for managing and governing data by linking, aligning, and binding ...

Enriched biodiversity data as a resource and service [PDF]

open access: yes, 2014
Background: Recent years have seen a surge in projects that produce large volumes of structured, machine-readable biodiversity data. To make these data amenable to processing by generic, open source “data enrichment” workflows, they are increasingly ...

Overcoming the Data Crisis in Biodiversity Conservation [PDF]

open access: yesTrends in Ecology & Evolution, 2018
How can we track population trends when monitoring data are sparse? Population declines can go undetected, despite ongoing threats. For example, only one of every 200 harvested species are monitored. This gap leads to uncertainty about the seriousness of declines and hampers effective conservation.

Leaftronics: Bio‐Fractal Scaffolds From Leaf Venation for Low‐Waste Electronics

open access: yesAdvanced Materials, EarlyView.
“Leaftronics” transforms naturally evolved leaf venation into quasi‐fractal scaffolds for sustainable electronics. Polymer‐infiltrated leaf skeletons can be used to fabricate ultra‐smooth, reflow‐ and thin‐film‐compatible decomposable substrates, while making the same lignocellulose networks conducting results in flexible transparent electrodes.
