Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

Why Homoscleromorph Sponges Have Ciliated Epithelia: Evidence for an Ancestral Role in Mucociliary Driven Particle Flux

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Epithelia are typically ciliated, except in sponges. Of all Porifera only Homoscleromorphs have motile cilia on their epithelia. Our data highlight the presence of cilia and mucociliary particle transport as a common feature of metazoa and a secondary loss in other sponge lineages.

Skeletogenic Expression of Integrin Alpha, Talin and Npnt Genes and Npnt Role in Sea Urchin Skeletogenesis

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Three integrin alpha genes and the cytoskeletal adaptor talin are enriched in sea urchin skeletogenic cells during early skeletogenesis. The extracellular matrix protein nephronectin (Npnt) is expressed in the skeletogenic cells throughout skeletogenesis and supports normal skeletal growth, highlighting a potential role for cell–matrix interactions in ...

A physiological investigation of the adaptive significance of juvenility in Pennantia corymbosa Forst : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Botany at Massey University [PDF]

open access: yes, 1978
The responses of the juvenile and adult growth forms of Pennantia corymbosa Forst. to a range of light intensities, leaf temperatures, shoot water potentials and wind velocities were investigated.

Dynamic benthic oxygen fluxes lessen hypoxia effects on open continental shelves

open access: yesLimnology and Oceanography, EarlyView.
Abstract Under the supposition that organisms inhabiting physically dynamic marine environments are better able to survive hypoxic conditions than those experiencing little turbulent or advective augmentation of oxygen fluxes, we evaluated summertime benthic macrofauna communities, in situ aquatic eddy covariance measurements, and ex situ sediment core

A framework linking silicon fertilisation, plant silicification and soil carbon cycling

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Soil organic carbon (SOC) is vital for soil health, food security, and climate change mitigation. We reviewed how silicon (Si) fertilisers, commonly used to improve plant health, may also influence SOC dynamics. We developed a framework linking Si and SOC and discussed the possibility of Si‐mediated plant changes contributing to SOC sequestration.

Y-organectomy in the crab, Scylla serrata [PDF]

open access: yes, 1982
Gabe (1953, 1956) first described the Y-organ in 58 species of Malacostraca. The Y-organ is a glandular structure of epidermal origin. It is located in the antennary/maxillary segments. The Y-organ varies in gross morphology and location in different

Proliferative and neoplastic aural pinna masses in a collection of African giant pouched rats (Cricetomys ansorgei)

open access: yesVeterinary Record Case Reports, EarlyView.
Abstract This case series describes aural lesions occurring in five African giant pouched rats (Cricetomys ansorgei) residing at a single zoological institution in southern California. Age of onset ranged from 3 to 7 years. Lesions occurred as single or multiple masses on one or both ears. A single case also developed a nasal mass.
