VASCULAR BUDDING IN BOTRYLLOIDES

The Biological Bulletin, 1959
1. Generally Botrylloides violaceum Oka propagates by palleal budding alone. Only when a small piece of a colony devoid of zooids is isolated, new buds are formed from the walls of the test vessels, i.e., vascular budding appears.2. As in Botryllus, these new buds are formed from aggregations of lymphocytes under the wall of the test vessels.3.

Non-Indigenous Species on Artificial Coastal Environments: Experimental Comparison between Aquaculture Farms and Recreational Marinas

Journal of Marine Science and Engineering, 2021
Globally, there is growing concern regarding the effects of the increasing anthropogenic pressures in marine communities. Artificial structures such as marinas and aquaculture facilities serve as invasion hotspots; hence, monitoring fouling communities ...

Immunohistochemical analysis of the adhesive papillae of Botrylloides leachi (Chordata, Tunicata, Ascidiacea): Implications for their sensory function [PDF]

, 2007
Most ascidian larvae settle and begin adhesion by means of three mucus secreting and sensory organs, the adhesive papillae or palps. However, the adhesive papillae of Botrylloides genus larvae, despite their name, have only a sensory function.

Colony specificity in Botrylloides leachi. II. Cellular aspects of the non-fusion reaction [PDF]

Invertebrate Survival Journal, 2007
We continued our study on fusion and non-fusion reactions in the compound ascidian Botrylloides leachi with particular attention to the role of hemocytes in the induction of the strong cytotoxic reaction observed when genetically incompatible colonies ...

Botrylloides leachii

, 2018
(25) Botrylloides leachii (Savigny, 1816) Status in U.K. – cryptogenic. Botrylloides leachii has been recorded at several monitoring programme sites, each year since 2014, from rapid assessment and scrape samples. It is considered cryptogenic in Europe (López-Legentil and Legentil 2015).

Effect of colonial tunicate presence on Ciona intestinalis recruitment within a mussel farming environment [PDF]

Management of Biological Invasions, 2012
Aquatic invasive species decrease yields and increase costs in aquaculture operations worldwide. Anecdotal evidence from Prince Edward Island (PEI, Canada) estuaries suggested that recruitment of the non-indigenous solitary tunicate Ciona intestinalis ...

Monitoring Non-indigenous Species in Port Habitats: First Application of a Standardized North American Protocol in the Mediterranean Sea

Frontiers in Marine Science, 2021
Baseline port monitoring for fouling communities is an essential tool to assess non-indigenous species (NIS) introduction and spread, but a standardized and coordinated method among Mediterranean and European countries has not yet been adopted.

The Miseno Lake (Central-Western Mediterranean Sea): An Overlooked Reservoir of Non-Indigenous and Cryptogenic Ascidians in a Marine Reserve

Frontiers in Marine Science, 2022
Ascidians are the largest and most diverse class of the subphylum Tunicata, and are important components of marine benthic communities. They are also renowned worldwide invaders, of growing concern due to ease of spread and impacts on native biota.
