South American Great Basin: Limnogeological analysis of the Salina del Bebedero Basin, Argentina (Late Pleistocene‐recent)

open access: yesThe Depositional Record, EarlyView.
. The Bebedero tectonic depression in San Luis province, Argentina, is a closed drainage basin that has formed as a result of block‐faulting and rifting processes. The Bebedero lake exhibits notable similarities to the endorheic watersheds of the western United States, particularly those of Death Valley, the Saline Valley and, to a lesser extent, the ...

Effects of life history strategies and habitats on limb regeneration in plethodontid salamanders

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Salamanders are the only tetrapods that exhibit the ability to fully regenerate limbs. The axolotl, a neotenic salamander, has become the model organism for regeneration research. Great advances have been made providing a detailed understanding of the morphological and molecular processes involved in limb regeneration.

When phylogenetics met biogeography: Willi Hennig, Lars Brundin and the roots of phylogenetic and cladistic biogeography

open access: yesCladistics, Volume 39, Issue 1, Page 58-69, February 2023., 2023
Abstract Willi Hennig's (Beitr. Ent. 1960, 10, 15) Die Dipteren‐Fauna von Neuseeland als systematisches und tiergeographisches Problem applied a phylogenetic approach to examine the distributional patterns exhibited by the Diptera of New Zealand. Hennig showed how phylogenetic trees may be used to infer dispersal, based on the progression and deviation

A zoogeographic model for the evolution of diversity and endemism in Madagascar

open access: yesEcography, EarlyView.
The delineation of zoogeographic regions is essential for understanding the evolution of biodiversity. Madagascar, characterized by high levels of endemism and habitat diversity, presents unique challenges and opportunities for such studies. Traditional global zoogeographic classifications, largely based on vertebrates, may overlook finer‐scale ...

A two‐dimensional morphospace for cyanobacteria and microalgae: Morphological diversity, evolutionary relatedness, and size constraints

open access: yesFreshwater Biology, Volume 68, Issue 1, Page 115-126, January 2023., 2023
Abstract Body metrics are considered as master traits that regulate physiological, behavioural and life history features of planktic cyanobacteria and microalgae. Although the distribution of their morphological traits reflects the various trade‐offs and strategies needed for survival in pelagic habitats, previous methods for quantifying phytoplankton ...

Mesoproterozoic surface oxygenation accompanied major sedimentary manganese deposition at 1.4 and 1.1 Ga

open access: yesGeobiology, Volume 21, Issue 1, Page 28-43, January 2023., 2023
Abstract Manganese (Mn) oxidation in marine environments requires oxygen (O2) or other reactive oxygen species in the water column, and widespread Mn oxide deposition in ancient sedimentary rocks has long been used as a proxy for oxidation. The oxygenation of Earth's atmosphere and oceans across the Archean‐Proterozoic boundary are associated with ...

Production of diverse brGDGTs by Acidobacterium Solibacter usitatus in response to temperature, pH, and O2 provides a culturing perspective on brGDGT proxies and biosynthesis

open access: yesGeobiology, Volume 21, Issue 1, Page 102-118, January 2023., 2023
Abstract Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are bacterial membrane lipids that are frequently employed as paleoenvironmental proxies because of the strong empirical correlations between their relative abundances and environmental temperature and pH.

Land use, hydroclimate and damming influence organic carbon sedimentation in a flood pulse wetland, Malaysia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Water bodies located in floodplains and tropical forests are known to be important carbon stores, but many are subjected to intensive pressures from damming, land use and climate changes. Sedimentary records preserve long‐term archives for understanding how such changes affect the quantity and quality of carbon stores.
