Enhanced rates of particulate organic matter remineralization by microzooplankton are diminished by added ballast minerals [PDF]

, 2013
To examine the potentially competing influences of microzooplankton and calcite mineral ballast on organic matter remineralization, we incubated diatoms in darkness in rolling tanks with and without added calcite minerals (coccoliths) and ...

Diversity of Rotifers in Small Rivers Affected by Human Activity [PDF]

, 2022
The rivers flowing through Upper Silesia and the adjacent areas (Southern Poland) are affected by various anthropogenic pressures including urbanisation, agriculture and animal husbandry, as well as industry (e.g., mining), which are reflected in the ...

Embryonic and larval development of the endangered Chiapas killifish Tlaloc hildebrandi (Cyprinodontiformes: Profundulidae)

Journal of Fish Biology, EarlyView.
Abstract The early ontogeny of endemic freshwater fishes provides essential baseline biological information for conservation and management, particularly in species with restricted distributions and high vulnerability to habitat degradation, environmental change and population decline. This study presents the first detailed description of embryonic and

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Water loss and morphological changes during desiccation in Macrotrachela quadricornifera (Rotifera, Bdelloidea)

, 2006
Bdelloid rotifers are aquatic microinvertebrates able to cope with the loss of environmental water and can, thus, live in temporal habitats. When water is evaporating, bdelloids contract into ‘tuns’, silence metabolism and lose water from the body.

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

Restoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Enriching Rotifers with “Premium” Microalgae. Nannochloropsis gaditana [PDF]

, 2009
The nutritive quality of Nannochloropsis gaditana cultured semicontinuously with different daily renewal rates was tested as a diet for short-term enrichment of the rotifer Brachionus plicatilis.

Mesophotic octocoral larval settlement preferences and behaviors

Restoration Ecology, EarlyView.
Abstract Introduction Lab‐based coral reproduction is advancing restoration efforts to support coral populations injured by the 2010 Deepwater Horizon oil spill. Objectives This study aimed to answer foundational questions concerning coral spawning and larval settlement that need to be resolved for these mesophotic and deep‐sea coral species before ...

La controverse Doyère-Pouchet sur la reviviscence animale et ses échos dans L’Homme à l’oreille casséed’Edmond About

Studia Romanica Posnaniensia, 2020
Rotifers and tardigrades, microscopic animals discovered in the 18th century, have exceptional abilities to survive in hostile conditions. Exposing them to desiccation, extreme temperatures, and vacuum, scientists wanted to determine whether ...
