Unravelling the identity of Pandora species (Bivalvia: Pandoridae) from Southern South America [PDF]

open access: yes, 2016
Four species of Pandora have been reported from southern South America: P. cistula Gould, 1850, P. braziliensis G. B. Sowerby II, 1874, P. diffissa Mabille & Rochebrune, 1889 and P. patagonica (Dall, 1915).

More Is Not Always Better: Selective Trait Filtering Governs Assembly Under Emerging Flow Intermittency

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
The study examined how increasing flow intermittency affects macroinvertebrate community organisation in newly drying headwater streams. Results showed that drying selectively filters species and trait states, with resistance‐ and resilience‐related survival strategies responding differently to increasing intermittency.

Gonad variation and development of freshwater mussel Chambardia rubens Lamarck, 1819 (Bivalvia: Mutelidae) from the River Nile in Egypt [PDF]

open access: yesJournal of Bioscience and Applied Research, 2018
The gametogenesis, reproductive cycle, and larval morphology of Chambardia rubens (Bivalvia: Mutelidae) are studied for the first time in Egypt. A total of 46 mussels were collected seasonally from winter to autumn 2017 from Benha (Qaluobiya Governorate)

Marine trophic architecture and hidden ecological connections in the Strait of Magellan: keystone species and ecosystem resilience

open access: yesOikos, Volume 2026, Issue 4, April 2026.
Understanding the ecological implications of species coexistence is central to biodiversity studies and to identify environmental and anthropogenic drivers of ecosystem dynamics, where ecological network analysis offers valuable insights. This study examines the complexity, structure, and potential responses to disturbances of the Strait of Magellan's ...

Multi‐barcoding‐based species identification using a hierarchical attention network with staged curriculum learning

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.
Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that
