Agroecological effect and sexual shape dimorphism in medfly Ceratitis capitata (Diptera: Tephritidae) an example in Croatian populations
(2020)The Mediterranean fruit fly or medfly, Ceratitis capitata (Wiedemann, 1824) is one of the most economically important fruit flies globally. Geometric morphometric methods based on principal component analyses, multivariate ...

Assessing the influence of allometry on sexual and non-sexual traits: An example in Cicindelidia trifasciata (Coleoptera: Cicindelinae) using geometric morphometrics
(2020)Based on a quantitative mathematical revolution, the study of morphology has had an important emphasis by developing statistical shape analysis. This made possible the combination of multivariate statistical methods and ...

Breaking symmetry. Fluctuating asymmetry and geometric morphometrics as tools for evaluating developmental instability under diverse agroecosystems
(2020)Fluctuating asymmetry (FA), in contrast with other asymmetries, is the bilateral asymmetry that represents small, random developmental differences between right and left sides. After nearly a century of using traditional ...

Breaking the law: Is it correct to Use the converse Bergmann rule in Ceroglossus chilensis? An overview using geometric morphometrics
(2024)The converse Bergmann’s rule is a pattern of body size variation observed in many ectothermic organisms that contradicts the classic Bergmann’s rule and suggests that individuals inhabiting warmer climates tend to exhibit ...

Ecomorphological analyses reveal impact of land-based stressors on stock structure of two commercially important fish species (Lutjanus synagris and Haemulon plumierii) in the Caribbean
(2021)Many Caribbean nations lack information on the ecology and biology of marine species, which are essential for food security and livelihoods in the region. This study aimed to advance the knowledge of two commercially ...

Fluctuating asymmetry as a method of assessing environmental stress in two predatory carabid species within mediterranean agroecosystems
(2020)Fluctuating asymmetry (FA) is used in assessing the effect of environmental stress on the development stability of individuals by measuring small random deviations from perfect bilateral symmetry. Here, we checked for FA ...

Genetic and morphological approach for western corn rootworm resistance management
(2021)The western corn rootworm (WCR), is one of the most serious pests of maize in the United States. In this study, we aimed to find a reliable pattern of difference related to resistance type using population genetic and ...

Integrating morphological and genetic data at different spatial scales in a cosmopolitan marine turtle species: Challenges for management and conservation
(2021)Patterns of genetic structure in highly mobile marine vertebrates may be accompanied by phenotypic variation. Most studies in marine turtles focused on population genetic structure have been performed at rookeries. We ...

Measuring the inter and intraspecific sexual shape dimorphism and body shape variation in generalist ground beetles in Russia
(2020)Ground beetles in multiple species vary greatly in the expression of the shape on sexual traits, resulting in a sexual shape dimorphism as a consequence of sexual selection differences. The present research focuses on the ...

Wing shape variation between terrestrial and coastal populations of the invasive box tree moth, Cydalima perspectalis, in Croatia
(2023)The box tree moth (Cydalima perspectalis Walker, 1859; Lepidoptera: Crambidae) is an invasive species naturally distributed in Asia. The caterpillars in all developmental stages cause damage through defoliation of plants, ...
