Reproductive Biology of the Smoothtail Spiny Lobster (Panulirus laevicauda) to Support Fisheries Management in Southeastern Brazil

Fisheries Management and Ecology, EarlyView.
ABSTRACT The smoothtail spiny lobster (Panulirus laevicauda) is one of the main target species for fisheries in Brazil. We aimed to estimate reproductive parameters of this species in support of a minimum legal size limit for the region. A sample of 508 individuals ranged 13.75–100 mm in cephalothorax length (CL) from the southern coast of Espírito ...

PI3Kγ in Tumour Inflammation: Bridging Immune Response and Cancer Progression—A Mini‐Review

Immunology, EarlyView.
Myeloid cell PI3Kγ can be activated by G Protein‐Coupled Receptors or Receptor Tyrosine Kinases. Once activated, PI3Kγ promotes integrin activation as well as Akt and mTOR activation, thereby promoting transcription of immune‐suppressive and pro‐angiogenic factors, such as Arginase, IL‐10, TGFβ and VEGF‐A.

Two's company: Monozygotic twinning in the small‐spotted catshark (Scyliorhinus canicula)

Journal of Fish Biology, EarlyView.
Abstract Developmental abnormalities in elasmobranchs (sharks and rays) are rarely documented, with reported cases primarily involving fin or cranial deformities. Monozygotic twinning, the formation of identical twins from a single zygote, is particularly rare in these species and has been observed overwhelmingly in viviparous elasmobranchs.

The effect of early life thermal environment on morphology and growth of yellow perch (Perca flavescens)

Journal of Fish Biology, EarlyView.
Abstract Early life development in fishes is a period of high phenotypic plasticity. Water temperatures during embryogenesis can lead to alterations in growth and metabolic and morphological phenotypic variations. This study aimed to characterize the effects of temperature on the growth and morphology of yellow perch throughout early development, a ...
