Abstract Environmental DNA (eDNA) data make it possible to measure and monitor biodiversity at unprecedented resolution scale. As use‐cases multiply scientific consensus grows regarding the value of eDNA analysis, public agencies have an opportunity decide how where fit into their mandates. Within United States, many federal state are individually using in various applications developing relevant expertise. A national strategy for implementation would capitalize on recent developments,...
Ecosystems globally are under threat from ongoing anthropogenic environmental change. Effective conservation management requires more thorough biodiversity surveys that can reveal system-level patterns and be applied rapidly across space time. Using modern ecological models community science, we integrate DNA Earth observations to produce a time snapshot of regional provide multi-scalar community-level characterization. We collected 278 samples in spring 2017 coastal, shrub, lowland forest...
Abstract Ecological monitoring of streams has frequently focused on measures describing the taxonomic, and sometimes functional, α diversity benthic macroinvertebrates ( BMI s) within a single sampled community. However, as many ecological processes effectively link stream communities there is need to describe groups using regional diversity. Here we demonstrate role for incorporating both traditional pairwise measure community turnover, β diversity, in assessing health well ζ more...
With national interest in seaweed-based biofuels as a sustainable alternative to fossil fuels, there is need for tools that produce high-yield seaweed cultivars and increase the efficiency of offshore farms. Several agricultural studies have demonstrated application microbial inoculants at an early life stage can improve crop yield, opportunity use similar techniques aquaculture. However, critical knowledge gap regarding host-microbiome associations macroalgae gametophytes germplasm...
Abstract Exposure to artificial light at night (ALAN) is a significant factor in ecological and epidemiological research. Although levels of exposure are frequently estimated from satellite-based measurements upward radiance, the correlation between radiance zenith sky brightness established, biologically relevant experienced all directions on ground has not been investigated. Because ground-based ALAN can depend local glare sources atmospheric scattering, studies using have relied an...
Summary The composition of digestive microbiomes is known to be a significant factor in the health variety hosts, including animal livestock. Therefore, it important ascertain how readily microbiome can significantly altered. To this end, role changing diet on Pacific oyster ( Crassostrea gigas) was assessed via weekly faecal sampling. Over course 12 weeks, isolated individual oysters were fed either control Tetraselmis algae Tet ) or treatment which shifted every 4 weeks. Weekly samples...
Camera image sensors can be used to detect ionizing radiation in addition optical photons. In particular, cosmic-ray muons are detected as long, straight tracks passing through multiple pixels. The distribution of track lengths related the thickness active (depleted) region camera sensor known angular at sea level. We use a sample muon recorded by Distributed Electronic Cosmic-ray Observatory measure depletion commercial smart phone, HTC Wildfire S. length prefers over an isotropic...
Microbial inoculants can increase the yield of cultivated crops and are successful in independent trials; however, efficacy drops large-scale applications due to insufficient consideration microbial community dynamics. The structure microbiomes, addition impact individual taxa, is an important factor consider when designing growth-promoting inoculants. Here, we investigate network assembly patterns Macrocystis pyrifera gametophyte germplasm cultures (collectively referred as a “seedbank”)...

Abstract Unique ecosystems globally are under threat from ongoing anthropogenic environmental change. Effective conservation management requires more thorough biodiversity surveys that can reveal system-level patterns and be applied rapidly across space time. We offer a way to use DNA, community science remote sensing together as methods reduce the discrepancy between magnitude of change historical approaches measure it. Taking advantages modern ecological models, we integrate DNA Earth...
Assessments of the ecological health algal assemblages in streams typically focus on measures their local diversity and classify individuals by morphotaxonomy. Such are often connected through various processes, such as dispersal, may be more accurately assessed components regional-, rather than local-scale assemblages. With recent declines costs sequencing computation, it has also become increasingly feasible to use metabarcoding species perform regional-scale bioassessments. Recently, zeta...
