Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Tama-risk? Avian responses to the invasion of saltcedars (Tamarix ramosissima) in Sonora, Mexico

Revista Mexicana de Biodiversidad, 2013
Although exotic plant invasions are one of the most important components of global change, previous studies have found some of the alien species to provide resources and/or conditions to native biota.

Spatial variation in the climatic predictors of species compositional turnover and endemism [PDF]

Ecology and Evolution, 2014
AbstractPrevious research focusing on broad‐scale or geographically invariant species‐environment dependencies suggest that temperature‐related variables explain more of the variation in reptile distributions than precipitation. However, species–environment relationships may exhibit considerable spatial variation contingent upon the geographic nuances ...

A multi-site method to capture turnover in rare to common interactions in bipartite species networks

, 2022
Ecological network structure is maintained by a generalist core of common species. However, rare species contribute substantially to both the species and functional diversity of networks.

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

FEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Uncovering the effects of grazing exclusion duration on plant richness and biomass in alpine grasslands using the price equation

Frontiers in Plant Science
Grazing exclusion is a key strategy for restoring degraded alpine grasslands. However, the mechanisms underlying plant species richness and biomass responses to long-term enclosure, particularly species turnover and biomass redistribution, remain unclear.

Cross-species comparison of global protein turnover kinetics and the role of turnover in aging

, 2021
Thesis (Ph. D.)--University of Rochester. Department of Biology, 2021.Protein homeostasis (proteostasis) is a dynamic set of coordinated cellular processes including protein synthesis, folding, localization, modification, and degradation. These processes

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.

Multiscale patterns of sponge diversity on Western Atlantic coral reefs: insights from the Southern Gulf of Mexico and the Mexican Caribbean

Frontiers in Marine Science
IntroductionSponges are increasingly dominant components of coral reefs in the Tropical Western Atlantic, yet patterns of their diversity across spatial scales remain poorly quantified.MethodsWe applied a hierarchical sampling design across 13 reefs and ...

Do commonly used indices of β-diversity measure species turnover?

, 2001
Indices of β-diversity are of two major types, (1) those that measure among-plot variability in species composition independently of the position of individual plots on spatial or environmental gradients, and (2) those that measure the extent of change ...
