Review of the southern African slender stonebashers, genus Heteromormyrus Steindachner 1866 (Teleostei: Mormyridae), with description of six new species

open access: yesJournal of Fish Biology, EarlyView.
Abstract Recent molecular studies have advanced our knowledge of the taxonomic diversity and generic placement of the slender stonebashers, previously placed in the genus Hippopotamyrus, in southern Africa. These fishes were recently transferred to the genus Heteromormyrus whose range encompasses the Kwanza, Kunene, Okavango, Zambezi, Pungwe and Buzi ...

New insights into Ituglanis (Siluriformes: Trichomycteridae) diversity in Bahia State, eastern Brazil: Description of a new species and conservation status reappraisal

open access: yesJournal of Fish Biology, EarlyView.
Abstract The northeastern Atlantic Forest of Brazil harbours a remarkable diversity of species of Trichomycteridae, many of which remain poorly understood. This study describes a new species of Ituglanis, endemic to the Ribeirão São Roque, a stream tributary of Rio Piabanha, an affluent of Rio Colônia basin, Bahia State, Brazil.

Morphological and molecular evidence reveals a new species of Characidium from the Ucayali‐Urubamba Piedmont, Peru, and novel molecular clades are proposed within the genus

open access: yesJournal of Fish Biology, EarlyView.
Abstract A new species of Characidium is described from the Urubamba River basin, within the Ucayali‐Urubamba Piedmont ecoregion, Peru. The new species can be readily distinguished from all congeners, except Characidium cacah, Characidium chicoi, Characidium helmeri, Characidium mirim, Characidium nana, Characidium nupelia, Characidium sterbai ...

On the conflict between science and ethics: the case of the moggel, Labeo umbratus (Teleostei: Cyprinidae) from South Africa

open access: yesJournal of Fish Biology, EarlyView.
Abstract Recent molecular evidence showed that Labeo umbratus comprises two allopatrically distributed genetic lineages, a northern lineage confined to the Orange‐Vaal River system where this species was originally described and a southern lineage with three geographically separated haplogroups (western, central and eastern) distributed across multiple

Lentipes ptasan, a new species of sicydiine goby (Teleostei: Gobioidei) from the Western Pacific, with a redescription of L. mindanaoensis

open access: yesJournal of Fish Biology, EarlyView.
Abstract Lentipes ptasan sp. nov. is described based on specimens collected from Taiwan and Mindanao Island. It is a large‐sized Lentipes species distinguished by several male‐specific characteristics, including an upper lip protruding beyond snout obviously, fewer premaxillary tricuspid teeth, two black lines running from the front of the eye through ...

Metastatic Spine Disease Alters Vertebral Load-To-Strength Ratios in Cancer Patients Compared to Healthy Individuals. [PDF]

open access: yesJOR Spine
This study investigated the effect of spinal bone metastasis (BM) on the biomechanical environment of the spine through estimates of load, strength, and the load‐to‐strength ratio (LSR). Our study suggests that task‐specific differences related to cancer, lesion type, and vertebral location differentially affect the biomechanical environment of the ...
