Population Structures and Levels of Connectivity for Scyphozoan and Cubozoan Jellyfish

open access: yesDiversity, 2021
Understanding the hierarchy of populations from the scale of metapopulations to mesopopulations and member local populations is fundamental to understanding the population dynamics of any species.

Major impact from a minor merger - The extraordinary hot molecular gas flow in the Eye of the NGC 4194 Medusa galaxy [PDF]

open access: yes, 2018
Minor mergers are important processes contributing significantly to how galaxies evolve across the age of the Universe. Their impact on supermassive black hole growth and star formation is profound.

Flow Structure and Transport Characteristics of Feeding and Exchange Currents Generated by Upside-Down Cassiopea Jellyfish [PDF]

open access: yes, 2012
Quantifying the flows generated by the pulsations of jellyfish bells is crucial for understanding the mechanics and efficiency of their swimming and feeding. Recent experimental and theoretical work has focused on the dynamics of vortices in the wakes of

Personal submersibles offer novel ecological research access to Antarctic waters: an example, with observations of the rarely encountered scyphozoan Stygiomedusa gigantea

open access: yesPolar Research, 2023
Underwater biological surveys have been conducted around the Antarctic continent for several decades, and our knowledge of the species present in the shallow waters (

Pattern regulation in a regenerating jellyfish

open access: yeseLife, 2020
Jellyfish, with their tetraradial symmetry, offer a novel paradigm for addressing patterning mechanisms during regeneration. Here we show that an interplay between mechanical forces, cell migration and proliferation allows jellyfish fragments to regain ...

Detecting patterns of species diversification in the presence of both rate shifts and mass extinctions [PDF]

open access: yes, 2015
Recent methodological advances are enabling better examination of speciation and extinction processes and patterns. A major open question is the origin of large discrepancies in species number between groups of the same age.

Medusa, a multithread 4-body decay fitting and simulation software [PDF]

open access: yesEPJ Web of Conferences
We present a new C++14 compliant application to perform physics data analyses of generic 4-body decays in massively parallel platforms. Medusa is highly based on Hydra, a header-only library which hides most of the complexities of writing parallel code ...

Evidence of Cnidarians sensitivity to sound after exposure to low frequency underwater sources [PDF]

open access: yes, 2016
Jellyfishes represent a group of species that play an important role in oceans, particularly as a food source for different taxa and as a predator of fish larvae and planktonic prey.

Atmospheric histories and growth trends of C4F10, C5F12, C6F14, C7F16 and C8F18 [PDF]

open access: yes, 2012
Atmospheric observations and trends are presented for the high molecular weight perfluorocarbons (PFCs): decafluorobutane (C4F10), dodecafluoropentane (C5F12), tetradecafluorohexane (C6F14), hexadecafluoroheptane (C7F16) and octadecafluorooctane (C8F18).

DISC BROOCHES WITH ANTHROPOMORPHIC DEPICTION GLASS INTAGLIOS IN THE SARMATIAN ENVIRONMENT OF THE GREAT HUNGARIAN PLAIN

open access: yesJournal of Ancient History and Archaeology, 2015
A special category of brooches present in the Sarmatian graves of the Carpathian Basin is represented by disc brooches made of silver or bronze plate with central anthropomorphic depiction glass intaglios.
