Extraordinary morphological changes in valve morphology during the ontogeny of several species of the Australian ostracod genus Bennelongia (Crustacea, Ostracoda)

open access: yesEuropean Journal of Taxonomy, 2013
Ostracods belonging to the genus Bennelongia differ much in valve morphology between adults and juveniles. Adult valves are asymmetrical, characterised by a beak-like feature in the antero-ventral region of the left valve, and, with some notable ...

On the Eggs and Instars of Scutigerella sp.*

open access: yesJournal of Cell Science, 1909
ABSTRACT This species is common in Amboina, very abundant in Ceram, and probably also in all the Moluccas, and perhaps other islands of Netherlands India. It lives chiefly, and in great numbers, in the black mould between the bark and the wood of rotten logs, in the rotten wood itself, under dead leaves, and under stones and pieces of ...

Determination of female-biased sexual size dimorphism in moths with a variable instar number: The role of additional instars [PDF]

open access: yesEuropean Journal of Entomology, 2006
While the ultimate causes and adaptive significance of sexual size dimorphism (SSD) have been extensively studied, the developmental mechanisms behind this phenomenon have received little attention. Going through an additional larval instar may form a specific way of achieving SSD in arthropods. In the present study, the mechanisms of SSD determination

TEMPERATURE CHARACTERISTICS FOR DURATION OF AN INSTAR IN CLADOCERANS [PDF]

open access: yesJournal of General Physiology, 1926
1. The temperature characteristics for the rate of development during a well defined instar were determined for three species of Cladocera, and found to be of the same general magnitudes as those obtained for rates of development and of O2 consumption in other arthropods. 2.

Multifunctional Framework Nucleic Acid Vehicle for Antibiotic Sensitization and Treatment of Methicillin‐Resistant Staphylococcus aureus

open access: yesAggregate, EarlyView.
A self‐assembling, aggregation‐enhanced tetrahedral DNA nanostructure (tFNA), termed TACs, enables localized accumulation and sustained release of ceftriaxone while co‐delivering antisense oligonucleotides that silence mecA, reduce PBP2a expression, and restore β‐lactam susceptibility in MRSA.
