Surfing along concentration filaments: sperm chemotaxis in physiological shear flows [PDF]
PLoS Comput Biol 17(4) e1008826 (2021), 2019 Many motile biological cells navigate along concentration gradients of signaling molecules: This chemotaxis guides for instance sperm cells from marine invertebrates, which have to find egg cells in the ocean. While chemotaxis has been intensively studied for idealized conditions of rotationally symmetric gradients in still water, natural gradients are

Earth-like and Tardigrade survey of exoplanets [PDF]
Life Sciences in Space Rsearch 2018, 2018 Finding life on other worlds is a fascinating area of astrobiology and planetary sciences. Presently, over 3500 exoplanets, representing a very wide range of physical and chemical environments, are known. Tardigrades (water bears) are microscopic invertebrates that inhabit almost all terrestrial, freshwater and marine habitats, from the highest ...

Global Change Biology, 2019 Although cross generation (CGP) and multigenerational (MGP) plasticity have been identified as mechanisms of acclimation to global change, the weight of evidence indicates that parental conditioning over generations is not a panacea to rescue stress ...

Neurons and Glia Cells in Marine Invertebrates: An Update
Frontiers in Neuroscience, 2020 The nervous system (NS) of invertebrates and vertebrates is composed of two main types of cells: neurons and glia. In both types of organisms, nerve cells have similarities in biochemistry and functionality.

Southern California fisheries monitoring summary for 1993 and 1994 [PDF]
, 1997 The southern California Monitoring and Management Units collectively gathered 803 discrete samples of 7,329 marine finfishes and invertebrates from local commercial fish markets or authorized fish transporters in 1993.

Preliminary estimates of mass-loss rates, changes in stable isotope composition, and invertebrate colonisation of evergreen and deciduous leaves in a Waikato, New Zealand, stream. [PDF]
, 1999 Rates of mass loss are important in the choice of tree species used in riparian rehabilitation because leaves that break down fast should contribute to stream food-webs more rapidly than leaves that break down more slowly.

Marine Invertebrates: Underexplored Sources of Bacteria Producing Biologically Active Molecules
Diversity, 2018 The marine bioprospecting could be considered as a new phenomenon, and already potentially more promising than terrestrial one in terms of possible discovery of new compounds. The secondary metabolites produced by associated-bacteria are actually studied

Optical magnetic detection of single-neuron action potentials using quantum defects in diamond [PDF]
PNAS 2016 113 (49) 14133-14138; November 22, 2016, 2016 A key challenge for neuroscience is noninvasive, label-free sensing of action potential (AP) dynamics in whole organisms with single-neuron resolution. Here, we present a new approach to this problem: using nitrogen-vacancy (NV) quantum defects in diamond to measure the time-dependent magnetic fields produced by single-neuron APs.

A cost-effective method to quantify biological surface sediment reworking [PDF]
, 2013 We propose a simple and inexpensive method to determine the rate and pattern of surface sediment reworking by benthic organisms. Unlike many existing methods commonly used in bioturbation studies, which usually require sediment sampling, our approach is ...

Role of self-propulsion of marine larvae on their probability of contact with a protruding collector located in a sea current [PDF]
, 2011 Settlement of marine larvae on a substrate is a fundamental problem of marine life. The probability of settlement is one of the quantitative characteristic of the settlement process. The probability of larval contact with a substrate is the upper bound of the probability of settlement.
