Riding the wetland wave: Can ducks locate macroinvertebrate resources across the breeding season?

open access: yesEcology and Evolution, Volume 14, Issue 6, June 2024.
Nektonic macroinvertebrate density varies across wetland types and over time during the waterfowl breeding season, with basin wetlands harboring the highest density and the most stable resources. Waterfowl pairs are able to track these densities and are found in the greatest numbers in the wetlands with the highest food density during the breeding ...

In search of the glow—Three‐dimensional reconstruction of Latia neritoides with specific focus on the mantel cavity (Mollusca; Gastropoda; Hygrophila)

open access: yesJournal of Zoology, Volume 323, Issue 2, Page 97-113, June 2024.
The unique defence system of Latia neritoides (Gastropoda) involves secretion of a luminescent mucus. More knowledge on this mucus system will be helpful to understand the basic principle of this luminescent biopolymer. The mucus has incredible underwater bonding abilities, opening up new possibilities for adhesives in moist environments. In this study,

Procambarus virginalis Lyko, 2017: A new threat to Iberian inland waters

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
We provide the first record of Procambarus virginalis in the Iberian Peninsula, based on morphological and genetic evidence (molecular barcoding of COI). We discuss its most plausible introduction pathways, update its global geographical distribution, highlight the potential impacts if it becomes invasive in Iberia and recommend some proposal ...

Embryonic Developmental Ecology of Freshwater Snail Lymnaea acuminata (Lymnaeidae: Gastropoda)

open access: yesPakistan Journal of Biological Sciences, 2006
The egg type of Lymnaea acuminata was determined as iso-lecithal and the cleavage is spirally holoblastic type. The development of L. acuminata was observed in details. Uncleaved zygote just after laying was found to contain a relatively yolk-free zone, the animal pole and the yolk-rich region, the vegetal pole.

Water quality shapes the community structure of zoobenthos in rivers but only has a minor effect on the fatty acid composition of zoobenthos and salmonids

open access: yesRiver Research and Applications, Volume 40, Issue 3, Page 436-451, March 2024.
Abstract Many river ecosystems in the boreal zone have faced remarkable changes due to intensive human activities, including land‐use changes in the catchments and channelization. Recently, restoration efforts have increased, hoping to restore a more natural hydromorphology.
