Mammalian Tolerance to Amino Acid Heterochirality

ChemBioChem, Accepted Article.
Organisms use amino acids predominantly in l‐configuration. On the other hand, a series of studies show that a variety of d‐amino acids also occur in mammals and amino acid homochirality is not complete. Mammals de novo synthesize most amino acids with l‐configuration, but serine and aspartate are converted from l‐ to d‐configuration by endogenous ...

Biodiversity in drinking water distribution systems:a brief review [PDF]

, 1997
In drinking water distribution systems, three groups of living organisms are usually found in the biofilm and circulating water: heterotrophic bacteria, free-living protozoa, and macro-invertebrates.

Lacustrine and fan‐delta sediments in syn‐rift lake basins

The Depositional Record, EarlyView.
A consistent model for the sequence framework and depositional pattern of asymmetric half‐grabens in syn‐rift lake basins bounded by active faults has been established, complementing existing models for marine rift successions. Syn‐rift lake basins are characterised by relatively small dimensions, steep slopes, poorly developed shoreline strata ...

Exposure of benthic invertebrates to sediment vibration: From laboratory experiments to outdoor simulated pile-driving [PDF]

Activities directly interacting with the seabed, such as pile-driving, can produce vibrations that have the potential to impact benthic invertebrates within their vicinity.

AquaMonitor: A multimodal multi-view image sequence dataset for real-life aquatic invertebrate biodiversity monitoring [PDF]

arXiv
This paper presents the AquaMonitor dataset, the first large computer vision dataset of aquatic invertebrates collected during routine environmental monitoring. While several large species identification datasets exist, they are rarely collected using standardized collection protocols, and none focus on aquatic invertebrates, which are particularly ...

An analysis of contractile and protrusive cell behaviors at the superficial surface of the zebrafish neural plate

Developmental Dynamics, EarlyView.
Abstract Background The forces underlying convergence and internalization of the teleost neural plate remain unknown. To help understand this morphogenesis, we analyzed collective and individual cell behaviors at the superficial surface of the neural plate as internalization begins to form the neural keel in the hindbrain region of the zebrafish embryo.

The role of serine hydroxymethyltransferase 1 (CHSHMT1) in the regulation of the key osmolyte glycine in the estuarine Hong Kong oyster Crassostrea hongkongensis under osmotic stress

Aquaculture Reports
The estuarine Crassostrea hongkongensis is the major cultured oyster species in the South China, and mass mortality induced by hyper-salinity has heavily damaged the oyster farming, especially during dry season.

Interspecific comparisons of anuran embryonic epidermal landscapes and energetic trade‐offs in response to changes in salinity

Developmental Dynamics, EarlyView.
Abstract Background Freshwater salinization is an emerging stressor in amphibian populations, and embryonic stages are most vulnerable. To better understand the variation in embryonic osmoregulation, we challenged embryos of two phylogenetically diverse anuran species, Xenopus laevis and Lithobates (Rana) sylvaticus, along a gradient of non‐lethal ...

The effects of intense fire on headwater streams of the Colville National Forest, WA [PDF]

, 2006
Thesis (M.S.) University of Alaska Fairbanks, 2006Forest fires play an important role in shaping ecosystems, and there has been growing concern on the effects of high intensity fires on forest and aquatic ecosystems.
