Biogeography of intertidal invertebrates is influenced by latitude along the west coast of Australia
Ecography, EarlyView.Along the west coast of Australia, intertidal rock platforms support high invertebrate diversities that provide vital ecosystem services, yet patterns in diversity are not well understood. Here, we document and examine the invertebrate assemblages on intertidal rock platforms in Western Australia and delineate ecoregions according to assemblage ...

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Phenotypic flexibility and the evolution of organismal design [PDF]
, 2003 Evolutionary biologists often use phenotypic differences between species and between individuals to gain an understanding of organismal design. The focus of much recent attention has been on developmental plasticity – the environmentally induced ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning
Journal 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

MICROPAPILLAE IN SEA URCHIN EGGS* [PDF]
Development, Growth and Differentiation, 1976 Sea urchin eggs fixed in a glutaraldehyde-calcium chloride mixture have "micropapillae" with a dense content. If these structures are real, they are likely to be sites where a fusion with the spermatozoon can take place. It is possible however that they represent some kind of preparation artefact without a structural counterpart in the living state.

Reconstructing Early Human Subsistence in Near Oceania: New Insights From Matenkupkum and Matenbek
International Journal of Osteoarchaeology, EarlyView.ABSTRACT The colonization of New Ireland ~44–40,000 years ago represents the earliest evidence of human occupation in Near Oceania. Yet, the precise impacts of climatic changes on subsistence strategies during the Late Pleistocene, Last Glacial Maximum, and Holocene remain poorly understood.
