The phenology of environmental DNA detection for coastal aquatic invasive species

Frontiers in Marine Science
Environmental DNA (eDNA) has transformed aquatic invasive species (AIS) surveillance, yet the temporal ecology of eDNA signals remains poorly understood.

Horizon scanning of potential threats to high‐Arctic biodiversity, human health and the economy from marine invasive alien species: A Svalbard case study

Global Change Biology, Volume 30, Issue 1, January 2024.
The high Arctic is becoming increasingly vulnerable to invasion by invasive alien species (IAS), as climate change leads to rapid loss of sea ice, changes in ocean temperature and salinity, and enhanced human activities. A group of experts in taxonomy, invasion biology and Arctic ecology carried out a horizon scanning exercise using the Svalbard ...

Oogenesis and oocyte envelope differentiation in the viviparous ascidianBotrylloides violaceus

Invertebrate Reproduction & Development, 1995
Summary Oogenesis and oocyte envelope differentiation were examined in the viviparous Botrylloides violaceus, a compound ascidian producing small alecithal eggs about 80 μm in diameter. Oogenesis was divided into five stages, defined according to ultrastructural changes in envelopes and oocyte growth.

The power of combined molecular and morphological analyses for the genus Botrylloides: identification of a potentially global invasive ascidian and description of a new species

, 2019
Botryllids are colonial styelid ascidians for which morphological characters distinguishing genera and species are often difficult to identify and frequently ambiguous.

Data_Sheet_1_Cryptic Diversity and Database Errors Challenge Non-indigenous Species Surveys: An Illustration With Botrylloides spp. in the English Channel and Mediterranean Sea.PDF

, 2019
Molecular tools have been extensively used in recent decades to examine biological invasion processes, and are increasingly being adopted as efficient tools to support non-indigenous species surveys, notably through barcoding approaches, i.e., the use of
