Clinically Diagnosed Decompensated Chronic Liver Disease With Suspected Portal Hypertension in a One-Year-Old Infant: Diagnostic Challenges in a Resource-Limited Setting. [PDF]

open access: yesClin Case Rep
ABSTRACT Chronic liver disease in infancy is uncommon, diagnostically demanding, and rarely reported from sub‐Saharan Africa, where advanced hepatologic evaluation is seldom accessible. We describe a one‐year‐old boy from rural Somaliland who presented with a two‐week history of progressive abdominal distension, followed by jaundice, hematemesis and ...

Symbiotic microalgae do not increase susceptibility of zooxanthellate medusae (Cassiopea xamachana) to herbicides

open access: yes, 2021
Herbicides are among the most detected pesticides in coastal environments. Herbicides may impact non-target organisms, but invertebrates that have a symbiotic relationship with microalgae (zooxanthellae) may be particularly susceptible. How zooxanthellae

Ecological and acoustic investigations of jellyfish (Scyphozoa and Hydrozoa) [PDF]

open access: yes, 2008
As the biomass of jellyfish (medusae of the Scyphozoa and Hydrozoa) has risen in numerous locations worldwide, awareness of their potential to exert a controlling influence on marine ecosystems and hinder the recruitment of fish stocks has increased ...

Claims That Anthropogenic Stressors Facilitate Jellyfish Blooms Have Been Amplified Beyond the Available Evidence: A Systematic Review

open access: yesFrontiers in Marine Science, 2018
The perception that anthropogenic stressors cause jellyfish blooms is widespread within the scientific literature and media but robust evidence in support of these claims appears scarce.

Fluctuation and diversity of Hydromedusae (Hydrozoa, Cnidaria) in a highly productive region of the Gulf of Mexico inferred from high frequency plankton sampling [PDF]

open access: yesPeerJ, 2019
Hydrozoa medusae undergo blooms and seasonal fluctuations; however the drivers of such fluctuations are unknown. To understand how medusa populations fluctuate in response to seasonal factors such as temperature, salinity, dissolved oxygen, and ...

Proterodiplostome Parasites (Digenea, Proterodiplostomidae) of the Caiman, Caiman crocodilus yacare (Reptilia, Crocodylia) in the Pantanal mato-Grossense, Brazil, with the description of two new species

open access: yesMemorias do Instituto Oswaldo Cruz, 1994
Two new species are described from the caiman. Caiman crocodilus yacare. Proterodiplostomum breve n. sp. differs from all other species in the genus by the following chacacteristics: (1) the paraprostate gland is shorter and club-shaped; (2) the genital ...

Behavioural and oceanographic isolation of an island-based jellyfish (Copula sivickisi, Class Cubozoa) population

open access: yesScientific Reports, 2021
Cubozoan jellyfish are classified as plankton despite the strong swimming and orientation abilities of cubomedusae. How these capabilities could affect cubozoan population structures is poorly understood.

Life Cycle Reversal in Aurelia sp.1 (Cnidaria, Scyphozoa).

open access: yesPLoS ONE, 2015
The genus Aurelia is one of the major contributors to jellyfish blooms in coastal waters, possibly due in part to hydroclimatic and anthropogenic causes, as well as their highly adaptive reproductive traits.

Extreme changes in salinity drive population dynamics of Catostylus mosaicus medusae in a modified estuary

open access: yes, 2021
Modifications to estuaries through the construction of barrages alter the natural dynamics of inhabitant species by controlling freshwater inputs into those systems. To understand the effects of modified freshwater flows on a native scyphozoan jellyfish,
