Temperature-dependent effect of filamentous cyanobacteria on Daphnia magna life history traits

open access: yesJournal of Limnology, 2011
Filamentous cyanobacteria are unsuitable food for Daphnia due to their poor manageability, poor nutritional value and, in some cases, toxicity. As the strength of harmful effects of cyanobacteria on filter-feeding zooplankton is temperature dependent ...

Comparative Molecular Insights into Developmental and Behavioral Toxicity Induced by Octocrylene and Ethylhexyl Salicylate Exposure on Zebrafish

open access: yesIntegrative Zoology, EarlyView.
This study compared the ecological toxicity of organic ultraviolet filters, octocrylene (OC) and ethylhexyl salicylate (EHS), on zebrafish embryos and larvae. EHS exhibited higher acute toxicity, causing increased mortality, hypoactive behavior at 50 mg/L, and disruptions in lipid homeostasis, while OC primarily affected hypoxia response and ...

Pengaruh Suhu Dan Kepadatan Ephippia Yang Berbeda Terhadap Penetasan Ephippia Daphnia magna
[The Influence Of Defferent Temperature And Ephippia Density For Ephippia Hatch Of Daphnia magna.]

open access: yesJurnal Ilmiah Perikanan dan Kelautan, 2009
Daphnia magna has good nutrition to carry on egg produce and fry of fish cupang, maskoki, oscar, tetra, and also can used for food source of fry and seed. Daphnia magna not only supply from natural environment, cause their growth deppend on fertilizer as

Transcriptomics Unveil Dsx1 as a Critical Regulator in Sexual Dimorphism of Crustaceans

open access: yesIntegrative Zoology, EarlyView.
Sexually dimorphic traits are involved in reproductive competition and are shaped by sex‐biased gene expression. This study identifies Dsx1 as a key male‐biased gene in Morinoia aosen and demonstrates through RNA interference that its disruption feminizes male‐specific T3 leg structures.

Holocene shoreline displacement and the impact of the Storegga tsunami on Hinnøya, northern Norway

open access: yesBoreas, EarlyView.
The Holocene relative sea‐level (RSL) history of Norway's largest island, Hinnøya, has been investigated in detail, using sediment records from 25 isolation basins. The sediments were analysed for macrofossil and phytoplankton content, which served as the basis for identifying marine–lacustrine transitions, that is isolation contacts. Terrestrial plant

Daphnia body size and population dynamics under predation by invertebrate and fish predators in Lago Maggiore: an approach based on contribution analysis

open access: yesJournal of Limnology, 2008
Predation on Daphnia is size-specific: while zooplanktivorous fish select large, ovigerous females, carrying larger clutches, predation by invertebrates, particularly Cladocera, is generally regarded as acting mainly on young, small, non-ovigerous ...

Size‐selective predation accounts for intra‐ and inter‐specific variation of inducible morphological defense of Daphnia

open access: yesEcosphere, 2020
Inducible defense is adaptive when prey organisms cope with fluctuations of predation risk, and there exists ample variations of inducible defense both within a species and between species even in a single habitat. Daphnia, a freshwater zooplankton genus,

Fungicide Non‐Target Effects Cause Reduced Sawfly Herbivory in Treated and Neighbouring Strawberry Plants

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Application of the fungicide Switch 62.5 WG in garden strawberry (Fragaria × ananassa), targeting Botrytis cinerea, reduced sawfly (Cladius spp.) herbivory by up to 94% and improved fruit quality. This non‐target effect also spilled over to neighbouring untreated plants, lowering damage by 46%.

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus

open access: yesThe FEBS Journal, EarlyView.
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not
