Collaborative Research: LTREB Renewal - River ecosystem responses to floodplain restoration (open access)

Collaborative Research: LTREB Renewal - River ecosystem responses to floodplain restoration

Data management plan for the grant, "Collaborative Research: LTREB Renewal - River ecosystem responses to floodplain restoration." This project centers on researching the metabolic transformations of the metal-contaminated Upper Clark Fork River in western Montana, USA, that are shifting with environmental restoration efforts. Specifically, the work conducted at UNT includes dissolved organic matter (DOM) chemical characterization of river samples along a 200 km transect from the Upper Clark Fork River, metal concentration analysis, and short-term incubation experiments on the river water (30 days of microbial processes) using multiple analytical chemistry techniques such as absorbance and fluorescence spectroscopy and atomic absorption spectroscopy or inductively coupled plasma mass spectrometry. Data will be analyzed to identify chemical and biological signals of restoration and assess ecosystem health.

Metabolic reprogramming underlies cavefish muscular endurance despite loss of muscle mass and contractility (open access)

Metabolic reprogramming underlies cavefish muscular endurance despite loss of muscle mass and contractility

Article discusses the Mexican cavefish Astyanax mexicanus, has lost moderate-to-vigorous activity following cave colonization, reaching basal swim speeds ~3.7-fold slower than their river-dwelling counterpart. Collectively, the authors reveal broad skeletal muscle changes following cave colonization, displaying an adaptive skeletal muscle phenotype reminiscent to mammalian disuse and high-fat models while simultaneously maintaining a unique capacity for sustained muscle contraction via enhanced glycogen metabolism.

Using CRISPR/Cas to enhance gene expression for crop trait improvement by editing miRNA targets (open access)

Using CRISPR/Cas to enhance gene expression for crop trait improvement by editing miRNA targets

Article states that gene editing tools such as CRISPR/Cas9 are often thought of as a means to prevent gene expression; however, a more subtle and yet powerful approach is the enhancement of gene expression by precise deletion of repressor sites within a gene of interest. Authors argue that gene editing of miRNA target sites is preferable over deletion of the miRNA genes themselves, given that it avoids the pitfalls of unspecific derepression of miRNA target(s) beyond the gene of interest.

The metabolic cost of turning right side up in the Mediterranean spur-thighed tortoise (Testudo graeca)

Article examining the the metabolic cost of self-righting in the terrestrial Mediterranean spur-thighed tortoise using respirometry and kinematic video analysis and comparing this to the metabolic cost of locomotion at a moderate, easily sustainable speed. The results found that self-righting is, relatively, metabolically expensive and costs around two times the mass-specific power required to walk.

The impact of multifactorial stress combination on plant growth and survival

Article studying seedlings of wild-type and different mutants of Arabidopsis thaliana plants subjected to a multifactorial stress combination of six different stresses, each applied at a low level, and their survival, physiological and molecular responses. Findings reveal that further polluting our environment could result in higher complexities of multifactorial stress combinations that in turn could drive a critical decline in plant growth and survival.

NSFDEB-NERC: Collaborative Research: Wildlife corridors: do they work and who benefits?

Data management plan for the grant, "NSFDEB-NERC: Collaborative Research: Wildlife corridors: do they work and who benefits?" Research on the impact of wildlife corridors using genetics as the measure of effectiveness. The study will use 20 independent landscapes to quantify how corridor traits affect gene flow, and will use non-flying mammals as focal species because they are strongly affected by fragmentation. The research team hypothesizes (1) a strong non-linear decline in success (gene flow) with corridor length, reflecting the skewed distribution of dispersal distances within species; (2) success will drop steeply as corridor width falls below a threshold, with the threshold determined by species traits; and (3) species that are bigger, are habitat specialists, or have greater dispersal abilities (relative to brain size or reproductive rate) will benefit more from corridors. Testing these hypotheses will allow generalization to a wide range of mammal species not included in this project. It will use highly flexible Random Forest models to answer the overarching question: What landscape traits (e.g., corridor width, degree of human disturbance) and species traits (mobility, affinity to particular land cover types) are associated with effective corridors?
