Consumer biodiversity increases organic nutrient availability across aquatic and terrestrial ecosystems
<p>Human land-use intensification threatens arthropod (e.g., insect and spider) biodiversity across aquatic and terrestrial ecosystems. Insects and spiders play critical roles in ecosystems by accumulating and synthesizing organic nutrients like polyunsaturated fatty acids (PUFA). However, links between biodiversity and nutrient content of insect and spider communities have yet to be quantified. We relate insect and spider richness to biomass and PUFA-mass from stream and terrestrial communities encompassing nine land-uses. PUFA-mass and biomass relate positively to biodiversity cross ecosystems. In terrestrial systems, human-dominated areas have lower biomass and PUFA-mass than more natural areas, even at equivalent levels of richness. Aquatic ecosystems have consistently higher PUFA mass than terrestrial ecosystems. Our findings reinforce the importance of conserving biodiversity and highlight unique benefits of aquatic biodiversity.<br><br>This is all of the data and code required to reproduce the analyses.

Latitudinal gradient in the intensity of biotic interactions in terrestrial ecosystems: Sources of variation and differences from the diversity gradient revealed by meta-analysis
<p>The Latitudinal Biotic Interaction Hypothesis (LBIH) states that the intensity of biotic interactions increases from high to low latitudes. This hypothesis, which may partly explain latitudinal gradients in biodiversity, remains hotly debated, largely due to variable outcomes of published studies. We used meta-analysis to identify the scope of the LBIH in terrestrial ecosystems. For this purpose, we explored the sources of variation in the strength of latitudinal changes in herbivory, carnivory, and parasitism (119 publications) and compared these gradients with gradients in the diversity of the respective groups of animals (102 publications). Overall, both herbivory and carnivory decreased towards the poles, while parasitism increased. The latitudinal gradient in herbivory and carnivory was threefold stronger above 50–60º than at lower latitudes and was significant due to interactions involving ectothermic consumers, studies using standardized prey (i.e. prey lacking local anti-predator adaptations) and studies aimed at testing LBIH. The poleward decrease in biodiversity did not differ between ectothermic and endothermic animals or among climate zones and was four-fold stronger than decrease in herbivory and carnivory. The discovered differences between the gradients in biotic interactions and biodiversity suggest that these two global macroecological patterns are likely shaped by different factors.</p>
Data and code for: Terrestrial eDNA survey outperforms conventional approach for detecting an invasive pest insect within an agricultural ecosystem
<p>Recent methodological advances permit surveys for terrestrial insects from the direct collection of environmental DNA (eDNA) deposited on vegetation or other surfaces. However, in contrast to well-studied aquatic applications, little is known about how detection rates for such terrestrial eDNA-based surveys compare with conventional survey methods. <i>Lycorma delicatula</i>, the spotted lanternfly, is an emerging invasive insect in eastern North America, and a significant ecological and economic pest of forested and agricultural systems, especially grapes. During fall 2019 we conducted two rounds of paired eDNA and visual surveys for spotted lanternflies within 48 plots at 12 vineyards in New Jersey, USA. We compared detection probabilities within a multimethod occupancy modeling framework and used the results to extrapolate and inform survey design. The probability of detecting spotted lanternflies given presence in a plot was over two times higher for eDNA (84%) versus visual surveys (36%). In mid-September, lanternfly eDNA was detected at five plots in three vineyards while visual surveys revealed only a single individual in one plot. In early October, after dispersal of lanternflies into vineyards, lanternfly eDNA was detected in 12 plots within six vineyards compared with visual detections in six plots in two vineyards. Extrapolations based on detection and local-scale occupancy rates indicate that only five and 12 plots would have been needed to positively detect lanternfly presence with 95% confidence using eDNA in contrast to 14 and 29 plots with visual surveys alone, respective to survey rounds. Log-linear models revealed that visual counts of lanternflies were positively related to eDNA concentrations (R<sup>2</sup> = 71%). We provide some of the first quantitative evidence to support the enhanced sensitivity of terrestrial eDNA approaches compared with conventional methods. Such methods can augment efforts to combat invasive species through improved ability to delimit invasion fronts, identify satellite populations, and confirm local eradications.</p>
Data from: Predator-driven behavioral shifts in a common lizard shape resource-flow from marine to terrestrial ecosystems
<p>We conducted a field experiment to assess foraging niche dynamics of semiarboreal brown anole lizards in the presence/absence of predatory ground-dwelling curly tailed lizards in a replicated set of island ecosystems. Data used in this study includes ecological infomration for the replicated islands of study (i.e. relative arthropod and seaweedabundances) together with phenotypic data of the lizards studied (body mass, size, body condition, as well as behavioral traits describing risk-taking behavior) as well as habitat use data and marine component of diet as a surrogate of the diet of these lizards. One year after experimental translocation, brown anoles exposed to these predators increased perch height and reduced consumption of marine-derived food resources. We also use this dataset to investigate if this foraging niche shift altered marine-to-terrestrial resource-flow dynamics and persisted in the diets of the first-generation offspring. Finally, we also assessed if lizards that displayed more risk-taking behaviors consumed more marine prey on islands with predators present.</p>

Global Terrestrial Ecosystem Carbon Flux Inferred from TanSat XCO2 Retrievals
<p>TanSat is China’s first greenhouse gases observing satellite. In recent years, substantial progresses have been achieved on retrieving column-averaged CO<sub>2</sub> dry air mole fraction (XCO<sub>2</sub>). However, relatively few attempts have been made to estimate terrestrial net ecosystem exchange (NEE) using TanSat XCO<sub>2</sub> retrievals. In this study, based on the GEOS-Chem 4D-Var data assimilation system, we infer the global NEE from April 2017 to March 2018 using TanSat XCO<sub>2</sub>. Evaluations against independent CO<sub>2</sub> observations and comparison with previous estimates indicate that the inverted land sinks in the northern middle latitudes and southern temperate regions are improved to a certain extent, however, they are obviously overestimated in northern high latitudes and underestimated in tropical lands (mainly northern Africa), respectively. </p> <p>There are 4 monthly mean variables in this dataset, including prior NEE, posterior NEE, prior ocean flux, and posterior ocean flux, which are all in a spatial resolution of 5 deg by 4 deg. </p>
