Effects of oligotrophication on fish growth: Insights from a mesocosm experiment

open access: yesLimnology and Oceanography, EarlyView.
Abstract Human activities can frequently affect aquatic ecosystems in irreversible ways, with flow regulation and water quality being major concerns. Dams can promote the retention of sediments and nutrients, increase water transparency, and reduce primary productivity, all of which characterize the oligotrophication process.

On the Embryology of a Mysid Crustacean, Hemimysis Lamornae

open access: yes
The study of the embryology of Hemimysis Lamornae , of which the following pages contain an account, was first undertaken with a view of tracing the later development of the mesoderm, and the formation of the heart and segmental excretory organs.

Fish predation cues induce drifting and emergence in an experimental stream mesocosm system

open access: yesLimnology and Oceanography, EarlyView.
Abstract Predator–prey interactions are important drivers of adaptation in aquatic communities, shaping the behavior of invertebrates with cascading effects on community dynamics. Behavioral responses, such as moving with the downstream current (drift) or altering the timing of emergence, are strategies that reduce the risk of predator encounters ...

Recent Advancements in the Characterization of D‐Amino Acid and Isoaspartate Post‐Translational Modifications

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT One of the great triumphs of mass spectrometry‐based peptide and protein characterization is the characterization of their modifications as most modifications have a characteristic mass shift. What happens when the modification does not change the mass of the peptide?

Expressions of Immune Prophenoloxidase (proPO) System-Related Genes Under Oxidative Stress in the Gonads and Stomach of the Mud Crab (Macrophthalmus japonicus) Exposed to Endocrine-Disrupting Chemicals

open access: yesAntioxidants
Endocrine-disrupting chemicals (EDCs) significantly damage biological systems related to reproductive, neurological, and metabolic functions. Approximately 1000 chemicals are known to possess endocrine-acting properties, including bisphenol A (BPA) and ...

Environmental Risk Assessment and Anti‐Corrosion Efficacy of Safe‐by‐Design Nitrite‐Based Nanomaterials for Maritime Applications

open access: yesNano Select, EarlyView.
The environmental behavior and impact of anti‐corrosion nanoadditives, ZnAl‐NO2 and MgAl‐NO2 layered double hydroxides (LDH), are assessed under marine conditions. These nanomaterials show instability in water but exhibit no or low toxicity to most tested marine species.

Could the library be dismantled/role of unique holdings in modern times [PDF]

open access: yes, 2011
I have been asked by administration, how much of our collection could go into storage. They optimistically hoping for a room or two for faculty/staff offices, as some buildings need renovation or need to be closed due to safety issues. Clearly, much of

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

open access: yesOikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.

A comparative analysis of crustacean exoskeletons: structural, microstructural, morphological, and UV absorption studies

open access: yesMaterials Research Express
This study aims to investigate the structural, thermal, and spectral characteristics, along with the ultra-violet (UV) absorption of various marine benthos exoskeletons, such as various species of crabs ( Portunus sanguinolentus, Portunus pelagicus ...
