Association between the BRCA2 N372H variant and male breast cancer risk: a population-based case-control study in Tuscany, Central Italy

open access: yesBMC Cancer, 2007
Background Male breast cancer (MBC) is a rare disease and little is known about its aetiology. Germ-line mutations of BRCA2 and, at lower frequency, of BRCA1 are implicated in a relatively small proportion of MBC cases.

Restoration age, distance from reference ecosystems, and host plant feeding guilds shape the diversity of frugivorous butterflies in ecological restoration areas in the Atlantic Forest

open access: yesRestoration Ecology, Volume 34, Issue 7, September 2026.
Abstract Introduction The fragmentation of the Atlantic Forest has caused severe biodiversity loss. In Paraná State, more than 96% of the original vegetation, predominantly semideciduous seasonal forest, has been degraded. Ecological restoration is a key strategy to reverse this scenario, aiming to recover environmental conditions equivalent to the ...

Breast cancer risk and 6q22.33: combined results from Breast Cancer Association Consortium and Consortium of Investigators on Modifiers of BRCA1/2.

open access: yesPLoS ONE, 2012
Recently, a locus on chromosome 6q22.33 (rs2180341) was reported to be associated with increased breast cancer risk in the Ashkenazi Jewish (AJ) population, and this association was also observed in populations of non-AJ European ancestry. In the present

Comparative study on nanostructured order-disorder in the wing eyespots of the giant owl butterfly, Caligo memnon. [PDF]

open access: yesIET Nanobiotechnol, 2018
International audienceA characteristic feature of the giant owl butterfly, i.e. Caligo memnon, is its big wing eyespot. This feature could serve as deceiving functionality for the butterfly against predators. As evidenced by scanning electron microscope (

Competition and habitat filtering shape Neotropical canopy butterfly communities across a rainfall seasonality gradient

open access: yesEcosphere, Volume 17, Issue 8, August 2026.
Abstract The stability hypothesis posits that stable environments provide species with predictable resources, where mechanisms that limit similarity, such as competition, are able to drive niche specialization and shape community composition. By contrast, variable and unpredictable environments are expected to allow only those species with appropriate ...

Fine-Scale Mapping at 9p22.2 Identifies Candidate Causal Variants That Modify Ovarian Cancer Risk in BRCA1 and BRCA2 Mutation Carriers.

open access: yesPLoS ONE, 2016
Population-based genome wide association studies have identified a locus at 9p22.2 associated with ovarian cancer risk, which also modifies ovarian cancer risk in BRCA1 and BRCA2 mutation carriers.

Behavioural responses to radio‐tag attachment in butterflies: Evidence for active tag removal

open access: yesEcological Entomology, Volume 51, Issue 4, Page 838-841, August 2026.
During controlled indoor flight experiments with 89 butterflies from eight tropical species, we monitored behavioural responses to dorsally attached radio tags using high‐speed video recordings. Four of 39 Morpho helenor exhibited coordinated abdominal flexion and hind leg movements directed toward the tag antenna during flight; in two individuals this

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

open access: yesAustral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.

The Coevolution of Colour Patterns and Hindwing Shapes on a Large Phylogenetic Scale Reveals Predation‐Driven Adaptive Syndromes in Swallowtail Butterflies

open access: yesEcology Letters, Volume 29, Issue 1, January 2026.
By combining computer vision and morphometrics on museum specimens, we show that hindwing tail shape and colour patterns evolved in concert across swallowtails. Long‐tailed species display contrasted stripes and marginal spots, suggesting coevolution of deflective traits promoted by natural selection by predators.

Outer bounds: Forest edges emulate vertical strata as a habitat filter for butterfly assemblages

open access: yesInsect Conservation and Diversity, Volume 18, Issue 6, Page 1013-1026, November 2025.
Species filtering converged between fragmentation and vertical strata based on functional traits and phylogenetic relatedness. The understory of continuous forests guarantees high taxonomic, phylogenetic, and functional diversity of butterfly assemblages.
