Captivating Colors, Crucial Roles: Astaxanthin’s Antioxidant Impact on Fish Oxidative Stress and Reproductive Performance

Animals, Journal Year: 2023, Volume and Issue: 13(21), P. 3357 - 3357

Published: Oct. 29, 2023

Fish, constantly exposed to environmental stressors due their aquatic habitat and high metabolic rates, are susceptible oxidative stress. This review examines the interplay between stress fish reproduction, emphasizing potent antioxidant properties of astaxanthin. Our primary objective is highlight astaxanthin's role in mitigating during critical reproductive stages, leading improved gamete quality, ovary development, hormone levels. We also explore its practical applications aquaculture, including enhanced pigmentation overall health. conducted a comprehensive literature review, analyzing studies on impact reproduction. Astaxanthin, carotenoid pigment, effectively combats reactive oxygen species, inhibiting lipid peroxidation maintaining membrane integrity. It significantly enhances success improves health aquaculture settings. reveals multifaceted benefits offering economic advantages aquaculture. Future research should delve into species-specific responses, optimal dosages, long-term effects astaxanthin supplementation inform sustainable strategies.

Improving the assessment of ecosystem and wildlife health: microbiome as an early indicator

Current Opinion in Biotechnology, Journal Year: 2023, Volume and Issue: 81, P. 102923 - 102923

Published: March 28, 2023

Human activities are causing dramatic declines in ecosystem health, compromising the functioning of life-support system, economic activity, and animal human health. In this context, monitoring health ecosystems wildlife populations is crucial for determining ecological dynamics assessing management interventions. A growing body evidence indicates that microbiome provides a meaningful early indicator Microbiome ubiquitous both environmental host-associated microbiomes rapidly reflect anthropogenic disturbances. However, we still need to overcome current limitations such as nucleic acid degradation, sequencing depth, establishment baseline data maximize potential studies.

Conserving Evolutionary Potential: Combining Landscape Genomics with Established Methods to Inform Plant Conservation

Annual Review of Plant Biology, Journal Year: 2024, Volume and Issue: 75(1), P. 707 - 736

Published: April 10, 2024

Biodiversity conservation requires conserving evolutionary potential-the capacity for wild populations to adapt. Understanding genetic diversity and dynamics is critical informing decisions that enhance adaptability persistence under environmental change. We review how emerging landscape genomic methods provide plant programs with insights into dynamics, including local adaptation its drivers. Landscape approaches explore relationships between variation environments complement rather than replace established population common garden assessing adaptive phenotypic variation, structure, gene flow, demography. Collectively, these inform actions, rescue, maladaptation prediction, assisted flow. The greatest on-the-ground impacts from such studies will be realized when practitioners are actively engaged in research monitoring. the shaping of species an uncertain future.

With super SDMs (machine learning, open access big data, and the cloud) towards more holistic global squirrel hotspots and coldspots

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: March 3, 2024

Abstract Species-habitat associations are correlative, can be quantified, and used for powerful inference. Nowadays, Species Distribution Models (SDMs) play a big role, e.g. using Machine Learning AI algorithms, but their best-available technical opportunities remain still not potential in the policy sector. Here we present Super SDMs that invoke ML, OA Big Data, Cloud with workflow best-possible inference 300 + global squirrel species. Such Data models especially important many marginalized species high number of endangered data-deficient world, specifically tropical regions. While our work shows common issues maxent algorithm (‘Shallow Learning'), here multi-species SDM template subsequent ensemble generic progress to tackle hotspot coldspot assessments more inclusive holistic

A Genomic‐Based Workflow for eDNA Assay Development for a Critically Endangered Turtle, Myuchelys georgesi

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(1)

Published: Jan. 1, 2025

ABSTRACT Environmental DNA (eDNA) analysis has become a popular conservation tool for detecting rare and elusive species. eDNA assays typically target mitochondrial (mtDNA) due to its high copy number per cell ability persist in the environment longer than nuclear DNA. Consequently, development of relied on reference sequences available online databases, or cases where such data are unavailable, de novo extraction sequencing mtDNA. In this study, we designed primers critically endangered Bellinger River turtle ( Myuchelys georgesi ) using bioinformatically assembled genome (mitogenome) derived from genome. We confirmed accuracy mitogenome by comparing it Sanger‐sequenced same species, no base pair mismatches were detected. Using extracted mitogenome, two 20 bp that 152‐base‐pair‐long fragment cytochrome oxidase 1 (CO1) gene 186‐base‐pair‐long B (CytB) gene. Both successfully validated silico , vitro situ .

Island biogeography and competition drive rapid venom complexity evolution across rattlesnakes

Evolution, Journal Year: 2025, Volume and Issue: unknown

Published: April 23, 2025

Abstract Understanding how human-mediated environmental change affects biodiversity is key for conserving evolvability. Because the most severe impacts are ongoing, such an understanding proving exceptionally difficult to attain. Islands natural, replicated experiments that serve as proxies habitat fragmentation and, therefore, allow us use historical changes in under Island Biogeography Theory (IBT) predict consequences of immediate anthropogenic on functional trait evolution. Rattlesnake venoms molecular phenotypes mediate interactions with prey, and diet venom complexity positively correlated. Consequently, rattlesnake investigate traits co-vary according IBT. We collected from 83 rattlesnakes across multiple species 11 islands Gulf California estimated using Shannon Diversity Index. Using a mixed effects modeling approach, we found number congenerics, island isolation, area best predicted variability. All variables exhibited negative relationship complexity, contrary predictions Larger more congenerics reduced perhaps reflecting niche partitioning specialization. Ultimately, used synthetic eco-evolutionary framework evolution fragmented landscapes.
