A Severity‐Agnostic Atrophy Pattern in Spinocerebellar Ataxia Type 3: Volumetrics from ENIGMA‐Ataxia

open access: yesMovement Disorders, EarlyView.
Background Spinocerebellar ataxia type 3 (SCA3) is a rare, inherited neurodegenerative disease characterized by progressive loss of motor coordination. Objectives We undertook a multisite magnetic resonance imaging study to profile the spatial spread of atrophy across the brain, determine whether atrophy preferentially maps onto specific functional ...

Effect of population reinforcement method, site, and plant characteristics on early establishment of the rare endemic plant species Minuartia smejkalii

open access: yesNordic Journal of Botany, EarlyView.
Many habitat‐specialist plant species have been endangered by fragmentation or destruction of their habitats. Minuartia smejkalii is a serpentinophyte endemic to the Czech Republic. It is highly threatened by recent habitat destruction and fragmentation, calling for effective conservation measures.

Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores

open access: yesOikos, EarlyView.
Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.

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 ...

Ecological significance of fruit displays in Myrtaceae: relationship between fruit colour, maturation stage, attractiveness and seed germination

open access: yesOikos, EarlyView.
Fruit colour has long fascinated scientists and is widely considered an evolutionary adaptation to attract both avian and mammalian frugivores. While fleshy fruits play a key role in plant–animal interactions by promoting seed dispersal, the functional significance of colour variation, particularly multicoloured displays during ripening, remains poorly
