Hidden gems: Scattered knowledge hampered freshwater jellyfish research over the past one‐and‐a‐half centuries

open access: yesEcology and Evolution, Volume 14, Issue 10, October 2024.
Approximately 150 years of research on freshwater jellyfish globally have resulted in a considerable amount of information. However, this is not comprehensively available to most researchers worldwide. Scattered information allows only for a fragmented view of the research field, which mediated by climate change received increasing importance.

High‐Resolution Longitudinal eDNA Metabarcoding and Morphological Tracking of Planktonic Threats to Salmon Aquaculture

open access: yesEnvironmental DNA, Volume 6, Issue 5, September–October 2024.
In the current study, we present and assess an exhaustive approach to identify the planktonic drivers of farmed Atlantic salmon complex gill disease (CGD) and fish mortality. We explored delayed or “lagged” effects of plankton abundances on gill health and undertook a comparison of environmental DNA (eDNA) metabarcoding and microscopy in their ability ...

Canyon effect and seasonal variability of deep-sea organisms in the NW Mediterranean: synchronous, year-long captures of "swimmers" from nearbottom sediment traps in a submarine canyon and its adjacent open slope [PDF]

open access: yes, 2017
Numerous organisms, including both passive sinkers and active migrators, are captured in sediment traps together with sediments. By capturing these “swimmers”, the traps become an extraordinarily tool to obtain relevant information on the biodiversity ...

The topological organization of the turtle cranium is constrained and conserved over long evolutionary timescales

open access: yesThe Anatomical Record, Volume 307, Issue 8, Page 2713-2748, August 2024.
Abstract The cranium of turtles (Testudines) is characterized by the secondary reduction of temporal fenestrae and loss of cranial joints (i.e., characteristics of anapsid, akinetic skulls). Evolution and ontogeny of the turtle cranium are associated with shape changes.
