Training and validation of an automated algorithm to differentiate no and minimal diabetic retinopathy from more severe stages in wide‐field images

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Diabetic retinopathy (DR) is a leading cause of blindness in the working‐age population. Screening is essential to identify and treat sight‐threatening stages prior to irreversible visual loss. This study aimed to train and validate an automated algorithm to identify no or minimal DR, potentially saving resources for specialist ...

Identifying the exposure of taxonomic, functional, and phylogenetic diversity of steppe birds to renewable energy development

open access: yesConservation Biology, EarlyView.
Abstract Biodiversity is globally threatened by human impacts, including land‐use transformation and climate change, which has prompted a rapid transition from fossil fuels to cleaner energy sources, such as photovoltaic (PV) energy. However, utility‐scale PV plants require vast areas and can lead to conflicts with biodiversity conservation, making ...

Ergebnisse aus den Mais Streifenversuchen 2017 [PDF]

open access: yes, 2017
Mais wird züchterisch stark bearbeitet. Das Sortenspektrum im Biolandbau unterscheidet sich bisher nur wenig vom konventionellen. Die Hochleistungshybriden (Doppelhybriden) sind speziell für intensive Ackerbaustandorte gezüchtet und sind heute Standard ...

Geographical distribution of the Pinnated Bittern (Botaurus pinnatus): Update and seasonal movement pattern

open access: yesIbis, EarlyView.
The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...
