Insights into the unique torpor of Botrylloides leachi, a colonial urochordate [PDF]
Developmental Biology, 2017 Rough environmental conditions make the survival of many multi-cellular organisms almost impossible, enforcing behavioral, morphological, physiological and reproductive rejoinders that can cope with harsh times and hostile environments, frequently through down-regulation of metabolism into basal states of dormancy, or torpor. This study examines one of

Transcriptome landscapes that signify Botrylloides leachi (Ascidiacea) torpor states
Developmental Biology, 2022 Harsh environments enforce the expression of behavioural, morphological, physiological, and reproductive rejoinders, including torpor. Here we study the morphological, cellular, and molecular alterations in torpor architype in the colonial urochordate Botrylloides aff. leachii by employing whole organism Transmission electron (TEM) and light microscope

Frontiers in Ecology and Evolution, 2023 Allorecognition, the ability of an organism to distinguish kin from non-kin, or self from non-self, has been studied extensively in a group of invertebrate chordates, the colonial ascidians called botryllids (Subphylum Tunicata, Class Ascidiacea, Family ...

Continued persistence of non-native ascidians in Southern California harbors and marinas [PDF]
Aquatic Invasions, 2023 Non-native ascidians have long dominated the artificial structures in southern California’s (United States) marinas and harbors. To determine the change in ascidian abundance and community composition over the last several decades, in 2019–2020 we ...

Checklist of ascidians (Chordata, Tunicata) from the southern Gulf of Mexico [PDF]
ZooKeys, 2019 This study is the first inventory of ascidians from shallow waters (0–25 m) of coastal and reef habitats in the southern Gulf of Mexico where ascidian diversity is poorly known.

The Developmental Cycle of Botrylloides [PDF]
Journal of Cell Science, 1947 ABSTRACT Of the many studies made on ascidians in the past, few have included the organism in its entirety. The present account is of the whole developmental cycle of an organism exhibiting exquisite timing in its four-dimensional relationships, with an interpretation of a colonial organism as the result of a few interacting processes. A

“Keep on rolling”: circulating cells in a botryllid ascidian torpor
Frontiers in Ecology and Evolution, 2023 Hemocytes of the colonial tunicate Botrylloides leachii play important roles throughout the animal’s life span, including transport and storage of nutrients, respiration, regeneration, budding, sexual reproduction, defense responses, and tunic generation.

Environment and shipping drive environmental DNA beta‐diversity among commercial ports
Molecular Ecology, Volume 32, Issue 23, Page 6696-6709, December 2023., 2023 Abstract The spread of nonindigenous species by shipping is a large and growing global problem that harms coastal ecosystems and economies and may blur coastal biogeographical patterns. This study coupled eukaryotic environmental DNA (eDNA) metabarcoding with dissimilarity regression to test the hypothesis that ship‐borne species spread homogenizes ...
