Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

open access: yesIntegrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

Nocturnal Behavior of Wintering Common Cranes (Grus grus) Under Varying Environmental Conditions

open access: yesIntegrative Zoology, EarlyView.
For diurnal species, nighttime represents a critical ecological boundary. Understanding the ecological determinants of nocturnal activity in taxa traditionally regarded as inactive after dusk is essential for elucidating the adaptive significance of nighttime behavior. We examined how night phase, nocturnal brightness (moon illumination and cloud cover)

Architecture on the Moon: Expanding the boundaries of Space

open access: yesПроект Байкал
The article examines the peculiarities of Soviet modernism of the 1960s – 1980s aimed at the spatial development of the country. The history of space exploration and attempts to conquer the Moon are also included in these processes. The article presents

Topology‐based Visual Analysis of Hydrothermal Plumes

open access: yesComputer Graphics Forum, EarlyView.
Abstract Hydrothermal plumes are turbulent structures of intense heat and mineral smoke that rise and disperse into the deep ocean. Existing models generally characterize these systems as a single axisymmetric plume originating from a point source. However, this assumption breaks down in weakly venting, spatially distributed systems, where low‐flux ...

Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Lunar base sustainability

open access: yes, 2005
A lunar base designed to operate over an extended period of time would be more practical if it were self-sustaining. The technology exists today to provide shelter, energy and oxygen to a fledging lunar base of six to ten astronauts.
