Differentially expressed morphological characters depend on sex and ontogenetic stage in the crab Goniopsis cruentata (Crustacea: Grapsidae)

open access: yesScientia Marina
The hypothesis of this study was that significant variations in the growth rates of Goniopsis cruentata are related to intersexual and age-related characteristics, particularly in areas identified as secondary sexual (pleon, carapace and chelipeds ...

Morphometric and External Injury Characterization of Rainbow Trout (O. mykiss) Used for Stocking in the Alpine River Inn (Bavaria, Germany)

open access: yesFisheries Management and Ecology, EarlyView.
ABSTRACT Stocking fish is a common practice in fisheries management, particularly for species of high conservation value or economic importance. Despite its widespread use, systematic evaluation of fish stockings remains scarce. This includes non‐native species such as rainbow trout (Oncorhynchus mykiss), which are intensively stocked into European ...

Time‐Dependent Debridement Quality of the SAF Infinitum System in Flat‐Shaped Root Canals

open access: yesInternational Endodontic Journal, EarlyView.
ABSTRACT Aim To evaluate the shaping ability, debris removal efficiency and morphological alterations induced by the SAF Infinitum system during progressive instrumentation of flat‐shaped root canals of mandibular incisors. Methodology Twelve extracted mandibular incisors with flat‐shaped canals were selected using micro‐CT and instrumented with 1.5‐mm

Ökomorphologie : Integration von Form, Funktion und Ökologie bei der Analyse morphologischer Strukturen [PDF]

open access: yes, 2008
Organisms are complex entities whose study has necessitated an increasingly reductionistic stance in modern biology (CAPLAN 1987). As a consequence, biology as a science has been split up into numerous sub-disciplines.

Scaling relationships between Haversian canal‐to‐secondary osteon and midshaft femur cortical‐to‐total area in a human autopsy sample

open access: yesJournal of Anatomy, EarlyView.
We report that femoral cortical thickness was strongly and negatively associated with secondary osteon porosity in an Australian autopsy sample, indicating that thicker cortices contained less porous secondary osteons. This allometric relationship held for the whole sample, males and sedentary well‐nourished individuals, but not for females or other ...

DNA barcoding and geometric morphometry of tabanid flies (Diptera: Tabanidae) in Thailand and a new record of a Thai horse fly

open access: yesMedical and Veterinary Entomology, EarlyView.
Tabanus tenens identified in this study is a newly recorded species in Thailand. DNA barcoding using the cox1 gene identified tabanid species in the present study. WGM data from different sites served as a reference for species identification. Abstract Tabanid flies are gaining high medical and veterinary importance due to their role as a vector of ...

Imaging and genetic toolbox to study Arabidopsis embryogenesis

open access: yesNew Phytologist, EarlyView.
Summary Embryogenesis in the model plant Arabidopsis thaliana provides a framework for understanding how cell polarity and patterning coordinate with hormonal signalling to establish the plant body plan. Following fertilisation, the zygote divides asymmetrically to generate apical and basal lineages, establishing the apical–basal axis that defines ...

Morphometry of the Pelvic Ring in Definition of Biomechanical Factors Influencing the Type of Pelvic Fracture [PDF]

open access: yes, 2009
The aim of the study was to supplement data on pelvic morphology and structural geometry. Using these data, a mathematical and biomechanical model was constructed. The research was divided into two parts. The first part comprised radiogrammetric analysis

Physiological cerebrospinal fluid interactions between brain and eye structures are altered after long‐duration spaceflight

open access: yesExperimental Physiology, EarlyView.
Abstract Long‐duration spaceflight represents an extreme challenge, triggering adaptive responses including spaceflight‐associated neuro‐ocular syndrome, characterized by diminished visual acuity and ocular changes, which is a significant health risk for Mars missions.
