Métodos químico e físico de indução í triploidia em Crassostrea gigas(Thunberg, 1793)
Boletim do Instituto de Pesca, 2018 Três métodos de indução í triploidia (3N) foram testados em ostras diploides (2N) (Crassostrea gigas): dois métodos químicos, citocalasina-B (CB) e 6-dimetilaminopurina (6-DMAP), e um método físico, com choque de temperatura.

The Anatomical Record, EarlyView.Abstract The tongue‐bite apparatus (TBA) is a secondary jaw system found in Osteoglossomorpha and, convergently, Salmonidae. It is thought to have similar prey‐processing functions as the pharyngeal jaws, possibly allowing the oral jaws to evolve separately for more efficient prey capture.

The evolution of mollusc shells [PDF]
WIREs Developmental Biology, 2018 Molluscan shells are externally fabricated by specialized epithelial cells on the dorsal mantle. Although a conserved set of regulatory genes appears to underlie specification of mantle progenitor cells, the genes that contribute to the formation of the mature shell are incredibly diverse.

The Anatomical Record, EarlyView.Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...

Comparative immunogenomics of molluscs [PDF]
Developmental & Comparative Immunology, 2017 Comparative immunology, studying both vertebrates and invertebrates, provided the earliest descriptions of phagocytosis as a general immune mechanism. However, the large scale of animal diversity challenges all-inclusive investigations and the field of immunology has developed by mostly emphasizing study of a few vertebrate species.

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species
Animal Research and One Health, EarlyView.A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome
