Revista Mexicana de Biodiversidad, 2012 The barnacle, Chelonibia testudinaria, is an obligate commensal of sea turtles that may show population variability according to the physical characteristics of the environment and properties of turtle hosts; therefore, we characterized the ...

DiversityBilateral symmetry is quite common in animals, but in some cases, asymmetry can be altered by hereditary or developmental processes. Symmetry may be preserved, or asymmetry may increase as the developmental stages progress.

Extreme Silk Toughness in Caerostris Spiders Is Limited to Adult Females
Integrative Zoology, EarlyView.We ask whether species with exceptionally tough silk, like Caerostris bark spiders, show different developmental patterns in silk toughness between ontogenetic stages and sexes. We found that only large females produce exceptionally tough silk with higher initial stiffness, while juvenile females as well as adult and juvenile males produce inferior ...

Sexual dimorphism in Aegla marginata (Decapoda: Anomura)
NaupliusA study on sexual dimorphism in Aegla marginata was conducted using geometric morphometric methods. The carapace of 47 females and 75 males and the left and right cheliped propodus of 29 females and 40 males were analyzed.

It's Complicated: How Sex, Family, and Season Affect Growth of a Sexually Size Dimorphic Spider
Integrative Zoology, EarlyView.Extreme female‐biased sexual size dimorphism (SSD) in Nephilingis cruentata emerges when male and female growth trajectories diverge mid‐development. Seasonal effects influence both sexes similarly, but family effects are strongly sex‐specific. These patterns identify a critical developmental window for mechanistic studies of SSD.

Offspring Defensive Investment Covaries With Brood Value in a Female Cobweb Spider
Integrative Zoology, EarlyView.We performed a thorough field investigation on the web architectures of Campanicola campanulata to research its cobweb architecture variation under the condition of whether it carried egg sacs, in order to test the theory of its brood value. Our results demonstrate that retreat construction in female cobweb spiders is modulated by brood value.

, 2017 "Carapace" è il risultato di una ricerca sulla sparizione, è legata ad una storia e ai luoghi che nel tempo sono ad essa riconducibili. In questo caso si tratta della scultura digitale del guscio di una tartaruga gigante, la "Cylindraspis vosmaeri" una

Integrative Zoology, EarlyView.We report the first ontogenetic information for the compression‐preserved Cambrian ecdysozoan worm Cricocosmia jinningensis. Its mosaic growth strategy unifies panarthropod and priapulid developmental patterns. Sclerite allometry reverses at the juvenile‐to‐adult transition, providing the earliest evidence of developmental resource allocation ...

Hydrodynamic performance of Ordovician archaeostracan carapaces
PLOS ONEThe diversification of macroscopic pelagic arthropods such as caryocaridid archaeostracans was a crucial aspect of the Great Ordovician Biodiversification Event, and the plankton revolution. A pelagic mode of life has been inferred for caryocaridids from their common presence in black graptolitic shales alongside carapace morphologies that appear ...
