A review of the Heteroclinus heptaeolus complex (Pisces: Blennioidei: Clinidae), with three new species and discussion of use of proportions in taxonomic studies.

The present paper reviews the Heteroclinus heptaeolus complex known only from temperate regions of Australia. Five species are recognised, with three of the species described as new, H. colemani, a deep bodied species often found around red algae, H.

From land to sea: Environmental DNA is correlated with long-term water quality indicators in an urbanized estuary.

Estuaries provide critical ecosystem services, and yet are increasingly under threat from urbanization. Non-invasive approaches to monitor biodiversity resident to or migrating through estuaries is critical to evaluate the holistic health of these ecosystems, often based entirely on water quality. In this study we compared tree of life metabarcoding (ToL-metabarcoding) biodiversity detections with measurements of physico-chemical variables (chlorophyll a, turbidity, total nitrogen, total phosphorous, dissolved oxygen) at eight sites of varying degrees of water quality in the Gold Coast Broadwater Estuary (Queensland, Australia).

Tree of life metabarcoding can serve as a biotic benchmark for shifting baselines in urbanized estuaries.

Urbanization of estuaries drastically changed existing shorelines and bathymetric contours, in turn modifying habitat for marine foundational species that host critical biodiversity. And yet we lack approaches to characterize a significant fraction of the biota that inhabit these ecosystems on time scales that align with rates of urbanization. Environmental DNA (or eDNA) metabarcoding that combines multiple assays targeting a broad range of taxonomic groups can provide a solution, but we need to determine whether the biological communities it detects ally with different habitats in these changing aquatic environments.

Successful Treatment of Refractory Chylous Ascites With Octreotide in a Patient With Decompensated Cirrhosis.

Chylous ascites is a rare manifestation of decompensated cirrhosis that is associated with increased short-term mortality. Exclusion of other etiologies must be performed to allow for appropriate management, which itself can be a challenge in the setting of decompensated cirrhosis. We report a case of chylous ascites in a patient with decompensated cirrhosis that was successfully managed with octreotide before liver transplantation.

The spotted parrotfish genome provides insights into the evolution of a coral reef dietary specialist (Teleostei: Labridae: Scarini: ).

With over 600 valid species, the wrasses (family Labridae) are among the largest and most successful families of the marine teleosts. They feature prominently on coral reefs where they are known not only for their impressive diversity in colouration and form but also for their functional specialisation and ability to occupy a wide variety of trophic guilds. Among the wrasses, the parrotfishes (tribe Scarini) display some of the most dramatic examples of trophic specialisation.
