Tooth eruption in the Early Cretaceous British mammal Triconodon and description of a new species
(
- Papers in Palaeontology
, 2020)
Triconodon mordax, from the lowest Cretaceous (Berriasian) part of the Purbeck Group, Dorset, is known by an ontogenetic series of specimens that document aspects of tooth eruption and replacement. Based on micro-computed ...
Sinking of Gelatinous Zooplankton Biomass Increases Deep Carbon Transfer Efficiency Globally
(
- Global Biogeochemical Cycles
, 2019)
Gelatinous zooplankton (Cnidaria, Ctenophora, and Urochordata, namely, Thaliacea) are ubiquitous members of plankton communities linking primary production to higher trophic levels and the deep ocean by serving as food and ...
Bacterial and archaeal lipids trace chemo(auto)trophy along the redoxcline in Vancouver Island fjords

Abstract
Marine oxygen minimum zones play a crucial role in the global oceanic carbon, nitrogen, and sulfur cycles as they harbor microbial communities that are adapted to the water column chemistry and redox zonation, and ...
Comment on ‘Kidron, G. J. (2018). Biocrust research: A critical view on eight common hydrological-related paradigms and dubious theses. Ecohydrology, e2061’
(
- Ecohydrology
, 2020)
According this discussion the eight putative paradigms advanced by Kidron (2018) cannot be upheld nor are they commonly held among hydrologists, ecologists, or microbiologists that
investigate biocrusts.
The Influence of Plankton Community Structure on Sinking Velocity and Remineralization Rate of Marine Aggregates
(
- Global Biogeochemical Cycles
, 2019)
Gravitational sinking of photosynthetically fixed particulate organic carbon (POC) constitutes a key component of the biological carbon pump. The fraction of POC leaving the surface ocean depends on POC sinking velocity ...
Desert breath—How fog promotes a novel type of soil biocenosis, forming the coastal Atacama Desert’s living skin
(
- Geobiology
, 2019)
The Atacama Desert is the driest non-polar desert on Earth, presenting precarious conditions for biological activity. In the arid coastal belt, life is restricted to areas with fog events that cause almost daily wet–dry ...
Infection of filamentous phytoplankton by fungal parasites enhances herbivory in pelagic food webs
(
- Limnology and Oceanography
, 2020)
Chytrid fungal parasites are ubiquitous in aquatic ecosystems and infect a wide array of aquatic organisms, including all phytoplankton groups. In addition to their role as parasites, chytrids serve as food to zooplankton, ...
Evaluating the role of coastal hypoxia on the transient expansion of microencruster intervals during the early Aptian
(
- Lethaia
, 2020-11-26)
Worldwide, a growing number of modern coastal marine ecosystems are increasingly exposed to suboxic‐ or even anoxic conditions. Low seawater oxygen levels trigger significant ecosystem changes and may result in mass mortality ...
Sporopollenin chemistry and its durability in the geological record: an integration of extant and fossil chemical data across the seed plants
(
- Palaeontology
, 2021-01-31)
Sporopollenin is a highly resistant biopolymer that forms the outer wall of pollen and spores (sporomorphs). Recent research into sporopollenin chemistry has opened up a range of new avenues for palynological research, ...
The Serbian Lake System: a stepping stone for freshwater molluscs in the middle Miocene
(
- Papers in Palaeontology
, 2020)
The first in-depth revision of a lacustrine freshwater mollusc fauna of the Serbian Lake System (SLS) is carried out. We describe and discuss well-preserved faunas from two localities in central and southern Serbia (Mađere ...
