Raw data of eDNA quantities from an experimental study testing temperature, water masses, and fish species
<p>Environmental DNA (eDNA) is a very promising approach to facilitate and improve the aquatic species monitoring, which is crucial for their management and conservation. In comparison with the plethora of monitoring studies in the fields, relatively few studies have focused on experimentally investigating the "ecology" of eDNA, in particular pertaining to processes influencing the detection of eDNA. The paucity of knowledge about its ecology hampers the use of eDNA analysis to its full potential. In this study, we experimentally evaluated the impact of several biotic and abiotic factors on the rate of production and degradation of eDNA. Individuals of three freshwater fish species (brown bullhead, tench, and yellow perch) with distinct ecology were placed in two types of water from the St. Lawrence River (Québec, Canada) with very distinct physicochemical characteristics and at three different temperatures. Water samples were then filtered at predetermined time intervals, and quantitative PCR was used to quantify the eDNA in each sample. We found that temperature, species, water types, and some interactions between these factors had a strong effect on the production and degradation of eDNA. The results of this study enhance our knowledge about the ecology of eDNA, thus improving eDNA data interpretation.</p>
Data for: Testing an invasion mechanism for Eucalyptus globulus: is there evidence of allelopathy?
<p><span><span><span><span><span><span><span><span><span><span><span><i>Premise of study</i>- Sparse understory communities, in association with non-native tree species, are often attributed to allelopathy, the chemical inhibition of one plant by another. However, allelopathy is a difficult ecological phenomenon to demonstrate with many studies showing conflicting results. <i>Eucalyptus globulus</i>, a native tree to Australia, is one of the most widely planted trees around the world. Sparse understories are common beneath <i>E. globulus</i>plantations and are often attributed to allelopathy, but the ecological impacts of <i>E. globulus</i>on native plant communities are poorly understood. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><i>Methods -</i>To assess allelopathy as a mechanism of understory inhibition, we tested volatile- and water-soluble leaf extracts on seed germination of California native plants. We also quantified germination rates and early seedling growth of native plants grown in soil from <i>E. globulus</i>plantations versus soil from an adjacent native plant community. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><i>Key results</i>- Volatile compounds from <i>E. globulus</i>did not significantly reduce germination for any species. Inhibition from water-soluble <i>E. globulus</i>compounds was comparable to that of a native tree, <i>Quercus agrifolia </i>(10%)<i>.</i><i>Eucalyptus globulus</i>soil supported germination and early seedling growth of native species equal to or better than coastal scrub soil, although species responses were variable. </span></span></span></span></span></span></span></span></span></span></span></p> <p><span><span><span><span><span><span><span><span><span><span><span><i>Conclusions</i>- In contrast to previous studies, our results fail to support the hypothesis that <i>E. globulus</i>chemically inhibits germination of native species. California native plants germinate and grow well in soils from <i>E. globulus</i>plantations, which may have significant implications for management and restoration of land historically occupied by <i>E. globulus</i>plantations. </span></span></span></span></span></span></span></span></span></span></span></p>

Netflow data with sampling 1000 for test (D6)
<p>NetFlow traffic generated using DOROTHEA (DOcker-based fRamework fOr gaTHering nEtflow trAffic) NetFlow is a network protocol developed by Cisco for the collection and monitoring of network traffic flow data generated. A flow is defined as a unidirectional sequence of packets with some common properties that pass through a network device.</p> <p>NetFlow flows have been captured with sampling 1000 at the packet level. A sampling means that 1 out of every X packets is selected to be flow while the rest of the packets are not valued.</p> <p>The version of NetFlow used to build the datasets is 5.</p>
Data from: Corn stover removal responses on soil test P and K levels in Coastal Plain Ultisols
<p>This is digital research data corresponding to a published manuscript,<em> </em><em><span>Corn stover removal responses on soil test P and K levels in Coastal Plain Ultisols</span></em><em>, </em>in<em> </em><em><span>Sustainability. </span></em><span>2021. 13:4401</span><span>.</span></p> <p><span>Corn (Zea mays L.) stover is used as a biofuel feedstock in the U.S. Selection of stover harvest rates for soils is problematic, however, because excessive stover removal may have consequences on plant available phosphorus (P) and potassium (K) concentrations. Our objective was to quantify stover harvest impact on soil P and K concentrations in the southeastern U.S. Coastal Plain. Five stover harvest rates (0, 25, 50, 75 and 100 percent by weight) were removed for five years (2008 to 2012) from replicated plots on highly weathered, toposequential Coastal Plain Ultisols. Grain and stover mass with P and K concentration data were used to calculate nutrient removal. Mehlich 1 (M1) extractable P and K concentrations and bulk density were used to monitor changes within the soil.</span></p>

<p class="MsoNormal"><strong><span>Background</span></strong></p> <p class="MsoNormal"><span>Aging population is rapidly expanding worldwide, and age-related cognitive impairments proves detrimental for achieving a better productive and quality of life. Lack of effective therapies for age-related cognitive impairment focuses attention on developing preventive strategies, such as nutritional interventions, cell therapies and environmental manipulations. The objective of present study was to explore the comparative benefits of potential memory-enhancing strategies like supplementation of choline and docosahexaenoic acid (DHA) or administration of conditioned media derived from human embryonic kidney stem cells (HEK-CM) or exposure to environmental enrichment (EE), that attenuates cognitive impairments in aging mice. </span></p> <p class="MsoNormal"><strong><span>Results</span></strong></p> <p class="MsoNormal"><span>Spatial memory and cognition were decreased in normal aging mice. Aged mice exposed to dietary Ch-DHA or HEK-CM showed significant enhancement in spatial learning tasks, memory and cognition compared to the same in age-matched NAC mice.

Figure 3 - Hind foot bones of Mazama rufina (A) and Pudu puda (B) sensu Hershkovitz (1982). According to Hershkovitz (1982; see also Brooke 1874, 1878), the union of the cuboideonavicular and external and middle cuneiform tarsal bones into a single bone in Pudu is the only osteological characteristic shared by P. puda and P. mephistophiles that consistently separates them from all other living deer, with exception of the genera Elaphodus and Muntiacus.
