Genome Architecture and Speciation in Plants and Animals
Molecular Ecology, Volume 34, Issue 22, November 2025.ABSTRACT There have been numerous treatments of specific topics in speciation, but surprisingly few papers have compared patterns and processes of speciation across different organismal groups. In this review, we partially address this gap by asking how variation in genome architecture impacts speciation across the plant and animal kingdoms.

Interspecific hybridization of sturgeon species affects differently their gonadal development
Czech Journal of Animal Science, 2018 Gonad development in fish is generally assumed to be negatively influenced by interspecific hybridization, resulting in sterility or sub-sterility. However, this is not the case in sturgeons (Acipenseridae), in which fertile hybrids are common.

Global Patterns and Drivers of Freshwater Fish Extinctions: Can We Learn From Our Losses?
Global Change Biology, Volume 31, Issue 5, May 2025.Nearly one‐third of freshwater fish species are currently at risk of extinction, with 100 species already lost. This study examines extinction patterns over the past 165 years, identifying habitat modification and loss, pollution, and invasive species as key drivers.

Unlocking the Secrets of Sturgeon Ecology: Lessons From Conservation Efforts in Northern Italy
Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 2, February 2025.ABSTRACT This study aimed to investigate the ecology of the Adriatic sturgeon (Acipenser naccarii) and Beluga sturgeon (Huso huso) in the Po basin in northern Italy, where both species have faced significant population declines. Using data collected from three LIFE projects, we investigated movement behaviour and habitat selection of the species ...
