Understanding marine biodiversity patterns and drivers: The fall of Icarus

open access: yesMarine Ecology, EarlyView.
Abstract Biodiversity patterns are fundamental in our understanding of the distribution of life, ecosystem function, and conservation. In this concept analysis, A survey of the existing knowledge on marine biodiversity patterns and drivers across latitudes, longitudes, and depths indicates that none of the postulated patterns represent a rule.

Tardigrade indexing approach on exoplanets [PDF]

open access: yesLife Sciences in Space Research, 2018
Finding life on other worlds is a fascinating area of astrobiology and planetary sciences. Presently, over 3800 exoplanets, representing a very wide range of physical and chemical environments, are known. Scientists are not only looking for traces of life outside Earth, but they are also trying to find out which of Earth's known organisms (ex ...

The genus Milnesium (Eutardigrada, Apochela, Milnesiidae) in Argentina: description of three new species and key to the species of South America

open access: yesEuropean Journal of Taxonomy, 2022
A revision of microscope slides deposited between 2014 and 2017 in the collection of Rocha and Doma (National University of La Pampa, Argentina) revealed three new species of the genus Milnesium Doyère, 1840: M. pelufforum sp. nov., M. irenae sp.

Restoration ecology in conflict along the Colorado front range

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Cheatgrass (Bromus tectorum) is a challenge to restoration in western North America. It attracts the attention of academic and government research scientists, weed managers, and chemical companies. Attempts to control it cause conflicts among these groups.

Tardigrades and Microscopes [PDF]

open access: yesMicroscopy Today, 2003
Abstract Commonly known as 'water bears', tardigrades are a phylum of microscopic animals that can be found living on mosses and lichens all over the world. The name Tardigrada means 'slow walker' which describes their sluggish, deliberate movements. Between these slow movements and their 'teddy bear' like appearance, tardigrades are the

Chasing (macro)elements in microinvertebrates: A new methodological approach for quantitative and qualitative analyses of phosphorus by PIXE (Particle‐Induced X‐Ray Emission) applied to glacier tardigrades

open access: yesMethods in Ecology and Evolution
Microinvertebrates in harsh environments often occupy the highest trophic levels and directly influence the turnover of macroelements. However, the investigation of their body elemental composition is complicated due to their low dry weight or sample ...

Comparative transcriptomics suggest unique molecular adaptations within tardigrade lineages

open access: yesBMC Genomics, 2019
Background Tardigrades are renowned for their ability to enter cryptobiosis (latent life) and endure extreme stress, including desiccation and freezing. Increased focus is on revealing molecular mechanisms underlying this tolerance.

New insights into the limited thermotolerance of anhydrobiotic tardigrades

open access: yesCommunicative & Integrative Biology, 2020
The recent discovery of an upper limit in the tolerance of an extremotolerant tardigrade to high temperatures is astounding. Although these microinvertebrates are able to endure severe environmental conditions, including desiccation, freezing and high ...

Deciphering the Biological Enigma—Genomic Evolution Underlying Anhydrobiosis in the Phylum Tardigrada and the Chironomid Polypedilum vanderplanki

open access: yesInsects, 2022
Anhydrobiosis, an ametabolic dehydrated state triggered by water loss, is observed in several invertebrate lineages. Anhydrobiotes revive when rehydrated, and seem not to suffer the ultimately lethal cell damage that results from severe loss of water in ...

How long can tardigrades survive in the anhydrobiotic state? A search for tardigrade anhydrobiosis patterns

open access: yesPLOS ONE, 2023
Anhydrobiosis is a desiccation tolerance that denotes the ability to survive almost complete dehydration without sustaining damage. The knowledge on the survival capacity of various tardigrade species in anhydrobiosis is still very limited. Our research compares anhydrobiotic capacities of four tardigrade species from different genera, i.e.
