Continental accumulation of fads2 copy numbers allows sticklebacks to thrive across a diversity of nutritional landscapes

open access: yesOikos, EarlyView.
Nutrients, including vital organic compounds, vary in availability across ecosystems, with the potential to act as a source of selection for traits that increase nutrient acquisition and biosynthesis. Compared to freshwaters, marine ecosystems are richer in the omega‐3 long‐chain polyunsaturated fatty acid (n‐3 LC‐PUFA) docosahexaenoic acid (DHA ...

Evidence for dispersal personality in the guppy across ecological conditions, with a minor effect of relative brain size

open access: yesOikos, EarlyView.
Individuals that disperse typically exhibit specific phenotypical traits that facilitate dispersal and settlement success, known as ‘dispersal syndromes'. Consequentially, characterizing dispersers is crucial to understand other processes such as metapopulation dynamics and biological invasions.

Ecological Aspects of Sexual Dimorphism

open access: yes, 2017
Sexual dimorphism represents a striking source of diversity in nature. This thesis focuses on empirically testing and conceptually unifying some of the non-exclusive adaptive causes of sexual dimorphism.

Sexual dimorphism of the incidence of significant relationships between selected parameters of feet and characteristics of trunk in adolescents aged 14 – 18 years

open access: yesJournal of Education, Health and Sport, 2018
Summary Introduction. Symmetry, asymmetry, mutual relationships and concomitance have become a subject of interest of numerous researchers. The analysis of the findings obtained in the own study conducted among adolescents aged 14-18 years revealed an ...

Matching habitat choice could be brightness‐based instead of hue‐based in green‐brown polymorphic grasshoppers

open access: yesOikos, EarlyView.
Some prey species have evolved background matching, that is they resemble their surrounding environment in terms of colour and/or brightness. When prey populations inhabit patchy environments, they may even have evolved specialised phenotypes: each phenotype matching a specific subset of patches.

Dress for success: climate pressures predict fur insulation and body size in natural and reintroduced populations of a threatened marsupial

open access: yesOikos, EarlyView.
Phenotypic variation in functional traits underpins responses to environmental gradients, influencing thermoregulation, energy balance, and long‐term persistence under climate extremes. Climate change is altering these gradients globally, yet in species that have already disappeared from much of their range, adaptive phenotypes may have also been lost,

Do morphometric measurements allow sex discrimination in Mockingbirds (Mimus sp)?

open access: yesAll Results Journals: Biol, 2016
Sexual dimorphism in birds may be expressed as differences in body size, plumage, color and/or behavior. Many species are monomorphic in color, making sex determination difficult in the field.

Prenatal Magnetic Resonance Imaging Assessment of Fetal Airway Dimensions: Establishing an Anthropometric Database

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective Fetal airway anomalies can severely impair breathing at birth, potentially causing brain injury or death. Thus, early prenatal diagnosis is essential. While MRI is the most effective imaging modality for evaluating fetal airways, normative MRI data remain scarce.

Ultrasound‐based renal growth curves in Chinese children aged 0–14 years

open access: yesPediatric Investigation, EarlyView.
Between June 2016 and July 2023, 6033 Chinese children aged 0–14 were recruited from our hospital using renal ultrasound examinations. This study provides comprehensive reference data for renal development in Chinese children aged 0–14 years, highlighting age‐related patterns and strong positive associations with height.
