RNA-Seq reveals that mitochondrial genes and long non-coding RNAs may play important roles in the bivoltine generations of the non-social Neotropical bee Tetrapedia diversipes [PDF]

open access: yesApidologie, 2017
In animals, voltinism is a result of evolutionary adaptations to environmental conditions. These evolutionary adaptations may profoundly affect the population structure and social organization level. To study the bivoltinism of the solitary bee Tetrapedia diversipes, we performed comparative transcriptomics analyses of foundresses and larvae from the ...

Effects of Macrobrachium nipponense on Phytoplankton Communities and Water Environmental Factors in Macrobrachium rosenbergii Culture

open access: yesAquaculture Research, Volume 2024, Issue 1, 2024.
Excessive feed input led to eutrophication and Cyanobacterial blooms in the culture of giant freshwater prawn (GFP, Macrobrachium rosenbergii). In order to improve the water quality and control the Cyanobacterial blooms, we tried the mixed culture of oriental river prawn (ORP, Macrobrachium nipponense), which can feed on plant and organic debris.
