Characterization of the Mycobiome of the Seagrass, Zostera marina, Reveals Putative Associations With Marine Chytrids.
Seagrasses are globally distributed marine flowering plants that are foundation species in coastal ecosystems. Seagrass beds play essential roles as habitats and hatcheries, in nutrient cycling, and in protecting the coastline from erosion. Although many studies have focused on seagrass ecology, only a limited number have investigated their associated fungi. In terrestrial systems, fungi can have beneficial and detrimental effects on plant fitness. However, not much is known about marine fungi and even less is known about seagrass associated fungi. Here we used culture-independent sequencing of the ribosomal internal transcribed spacer (ITS) region to characterize the taxonomic diversity of fungi associated with the seagrass, Zostera marina. We sampled from two Z. marina beds in Bodega Bay over three time points to investigate fungal diversity within and between plants. Our results indicate that there are many fungal taxa for which a taxonomic assignment cannot be made living on and inside Z. marina leaves, roots and rhizomes and that these plant tissues harbor distinct fungal communities. We also identified differences in the abundances of the orders, Glomerellales, Agaricales and Malasseziales, between seagrass tissues. The most prevalent ITS amplicon sequence variants (ASVs) associated with Z. marina tissues could not initially be confidently assigned to a fungal phylum, but shared significant sequence similarity with Chytridiomycota and Aphelidomycota. To obtain a more definitive taxonomic classification of the most abundant ASV associated with Z. marina leaves, we used PCR with one primer targeting a unique region of this ASV's ITS2 and a second primer targeting fungal 28S rRNA genes to amplify part of the 28S rRNA gene region corresponding to this ASV. Sequencing and phylogenetic analysis of the resulting partial 28S rRNA gene revealed that the organism that this ASV comes from is a member of Novel Clade SW-I in the order Lobulomycetales in the phylum Chytridiomycota. This clade includes known parasites of freshwater diatoms and algae and it is possible this chytrid is directly infecting Z. marina leaf tissues. This work highlights a need for further studies focusing on marine fungi and the potential importance of these understudied communities to the larger seagrass ecosystem
WIC Improves Child Health and School Readiness
New research by Children's HealthWatch demonstrates that young children who participate in the Special Supplemental Nutrition program for Women, Infants, and Children (WIC) are more likely to be in excellent or good health and have a reduced risk of developmental delay. Investing in WIC supports the nutritional and health needs of young children during a critical window of brain and body growth.Progam improvements that decrease access barriers, provide the full amount of fruits and vegetables recommended by the Institute of Medicine, and accommodate working parents' schedules will help young children reach their full potential
Energy Insecurity is a Major Threat to Child Health
With the recession and this winter's harsh weather, many families are facing a choice between eating and heating. Research by Children's HealthWatch shows that young children whose families struggle to pay their utility bills ('energy insecure' families) are more likely to suffer a host of problems including food insecurity, poor health, hospitalizations and developmental delays.The Low Income Home Energy Assistance Program (LIHEAP), which provides low-income households with assistance in paying their utility bills, is effective at shielding young children from the harmful effects of energy insecurity.According to research by Children's HealthWatch, young children whose families received LIHEAP were less likely to be at risk for growth problems and had healthier weights for their age.By appropriating the maximum authorized funding for LIHEAP and ensuring that climate change legislation buffers vulnerable families and children from the harmful effects of higher energy prices, Congress will be taking important steps to protect children's health
Child Care Feeding Programs Support Young Children's Healthy Development
New research by Children's HealthWatch shows that toddlers from low-income families who receive meals from their child care provider - those likely to be receiving CACFP - are in better health, have decreased risk for hospitalization, and are at healthier heights and weights for their age than those whose have to bring meals from home. As the nation's only nutrition program for young children in child care, CACFP is a critical component of a comprehensive approach to child nutrition.Changes to CACFP that expand access, reduce barriers and ensure that child care providers have the resources they need to provide healthy meals are beneficial for young children's health, growth and development
Management of incidentally detected heart murmurs in dogs and cats
A dog or a cat has an incidentally detected heart murmur if the murmur is an unexpected discovery during a veterinary consultation that was not initially focused on the cardiovascular system. This document presents approaches for managing dogs and cats that have incidentally-detected heart murmurs, with an emphasis on murmur characteristics, signalment profiling, and multifactorial decision-making to choose an optimal course for a given patient
LIHEAP Stabilizes Family Housing and Protects Children's Health
The heating and cooling season presents special challenges for our nation's low-income families. With limited resources, many are challenged to manage the seasonal spike in utility expenses, facing decisions about whether to pay the rent, keep the lights and heat on, or buy enough groceries to get through the end of the month. We know that each of these decisions will have significant implications for the health of their youngest children. Unfortunately, these tough choices are all too common this winter as the nation experiences increases in energy prices, unusually cold weather, and continued high unemployment
Boost to SNAP Benefits Protected Young Children's Health
The Great Recession has taken a significant toll on America's children. In 2010, 25 percent of children under age six were living in poverty, up from 21 percent in 2007
Overcrowding and Frequent Moves Undermine Children's Health
Children need stability in their lives -- whether it is in their daily routines, the adults that care for them, or their housing. Recent economic conditions are putting families at risk, not just of outright homelessness but of being housing insecure (frequent moves, overcrowding, or doubling up with another family for economic reasons)
