Macroecological and Biogeographic Patterns of Kinorhyncha in the Iberian Peninsula

open access: yesJournal of Biogeography, Volume 52, Issue 11, November 2025.
ABSTRACT Aim Biogeography and macroecology aim to understand the processes that determine patterns in nature. In the marine environment, most of what we know has been documented for fish and macrobenthic organisms. As a result, this knowledge is negatively biased towards smaller benthic organisms, including meiofauna.

p‐Type β‐Ga2O3 Homoepitaxial Films with Superior Electrical Transport Properties

open access: yesAdvanced Electronic Materials, Volume 11, Issue 16, October 6, 2025.
High‐quality p‐type β‐Ga2O3 thin films are simultaneously grown by MOCVD on (010) and (–201) single crystal substrates. While the (–201) film shows typical semiconductor behavior, the (010) sample exhibits superior electrical properties. The study reveals orientation‐driven difference in electrical transport, supported by structural and microscopic ...
