Sherbo et al. 2023 Data Package. Data associated with study assessing effects of dissolved organic matter on phytoplankton productivity in boreal lakes. The majority of data was collected in 2018 at the IISD Experimental Lakes Area in Northwestern Ontario
Allochthonous dissolved organic matter (DOM) structures many physical, chemical, and biological properties of lakes, including key variables that control productivity at the base of freshwater food webs. We examined phytoplankton biomass and productivity and their drivers, across eight pristine boreal lakes with DOM ranging from 3.5 to 9.5 mg DOC L-1. Increases in DOM were associated with significant increases in epilimnetic nitrogen, phosphorus and chlorophyll a (Chl a) concentrations suggesting that nutrients associated with DOM stimulate phytoplankton biomass and productivity. Such results were misleading; there was no significant relationship between Chl a and phytoplankton biomass measured via microscopy, and results did not incorporate the effects of DOM on thermocline and euphotic depth. Chl a:biomass and Chl a: carbon ratios indicated that increases in Chl a with DOM were driven by photo-acclimation to declining light availability. Increases. Further, increases in DOM led to large declines in thermocline (~50 %) and euphotic (~75 %) depths, and depth-integrated phytoplankton biomass and primary production (~70 %).

Effect of Long-Term Nitrogen Fertilization on Mycorrhizal Fungi Associated with a Dominant Grass in a Chihuahuan Desert Grassland at the Sevilleta National Wildlife Refuge, New Mexico (2005)
We studied the diversity of arbuscular mycorrhizal fungi (AMF) in a semiarid grassland and the effect of long-term nitrogen (N) fertilization on this fungal community. Root samples of Bouteloua gracilis were collected at the Sevilleta National Wildlife Refuge (New Mexico, USA) from control and N-amended plots that have been fertilized since 1995. Small subunit rDNA was amplified using AMF specific primers NS31 and AM1. The diversity of AMF was low in comparison with other ecosystems, only seven operational taxonomic units (OTU) were found in B. gracilis and all belong to the genus Glomus. The dominant OTU was closely related to the ubiquitous G. intraradices/G. fasciculatum group. N-amended plots showed a reduction in the abundance of the dominant OTU and an increase in AMF diversity. The greater AMF diversity in roots from N-amended plots may have been the result of displacement of the dominant OTU, which facilitated detection of uncommon AMF. The long-term implications of AMF responses to N enrichment for plant carbon allocation and plant community structure remain unclear.

Individual dietary specialization in a generalist bee varies across populations but has no effect on the richness of associated microbial communities
<p><span></span></p> <p>Despite the increasingly documented occurrence of individual specialization, the relationship between individual consumer interactions and diet-related microbial communities in wild populations is still unclear. Using data from nests of the bee <em>Ceratina australensis</em> from three different wild populations, we combine metabarcoding and network approaches to explore the existence of individual variation in resource use within and across populations, and whether dietary specialization affects the richness of pollen-associated microbes. We reveal the existence of marked dietary specialization. In the most specialized population, we also show that individuals' diet breadth was positively related to the richness of fungi, but not bacteria. Overall, individual specialization appeared to have a weak or negligible effect on the microbial richness of nests, suggesting that different mechanisms beyond environmental transmission may be at play regarding microbial acquisition in wild bees.</p>

Selpercatinib treatment of RET mutated thyroid cancers is associated with gastrointestinal adverse effects
<p><strong>Background:</strong></p> <p>Metastatic medullary thyroid carcinoma (MTC) and radioactive iodine refractory differentiated thyroid carcinoma (RAI-R DTC) have poor prognosis and limited treatment options. Selpercatinib (LOXO-292), a selective kinase inhibitor targeting the <em>RET</em> gene, has shown a 69-79% objective responses have been observed in this cohort (1) with benefits in other tumours harbouring the same oncogenic driver (2). Published reports describe only 17% of patients experiencing gastrointestinal Adverse effects (AE) which is in contrast to our local experience. Here we characterise the AE and correlate with radiological and histopathological findings. </p> <p><strong>Methods:</strong></p> <p>Sequential patients enrolled in LIBRETTO-001 at Royal North Shore Hospital, Sydney with available imaging (n=22) were recruited. Patients had regular visits with AE documented and CT scans 3 monthly. CT at screening, at time of gastrointestinal AE and at most recent follow up were reviewed and scored. Endoscopic examination was performed in five patients.</p> <p><strong>Results:</strong></p> <p>Of 22 patients in this cohort, the majority had somatic <em>RET </em>alterations (n=18), most commonly <em>p.Met918Thr</em> (n=14). Ten patients (50%) developed gastrointestinal adverse effects. Dose reduction was required in 8 of the 10 patients, but none discontinued therapy. The majority had stable disease (n=17). Gastric and small bowel oedema was evident in symptomatic patients after a median time of 67 weeks’ treatment. Histological correlation in five patients revealed mucosal oedema correlating with radiological evidence of congestion and oedema.</p> <p><strong>Discussion: </strong></p> <p>Gastrointestinal AEs with selpercatinib may be more common than previously described. Most are self-limiting but often require dose adjustments. Histological evidence of mucosal oedema observed in conjunction with the radiological findings of congestion and wall thickening suggest that bowel wall oedema is a predominant mechanism of abdominal pain in these patients.</p>
Data associated with: Emergence of the physiological effects of elevated CO2 on land-atmosphere exchange of carbon and water
<p>Elevated atmospheric CO<sub>2</sub> (eCO<sub>2</sub>) influences the carbon assimilation rate and stomatal conductance of plants and thereby can affect the global cycles of carbon and water. Yet, the detection of these physiological effects of eCO<sub>2</sub> in observational data remains challenging, because natural variations and confounding factors (e.g., warming) can overshadow the eCO<sub>2</sub> effects in observational data of real-world ecosystems. In this study, we aim at developing a method to detect the emergence of the physiological CO<sub>2</sub> effects on various variables related to carbon and water fluxes. We mimic the observational setting in ecosystems using a comprehensive process-based land surface model QUINCY to simulate the leaf-level effects of increasing atmospheric CO<sub>2</sub> concentrations and their century-long propagation through the terrestrial carbon and water cycles across different climate regimes and biomes. We then develop a statistical method based on the signal-to-noise ratio to detect the emergence of the eCO<sub>2</sub> effects. The signal in gross primary production (GPP) emerges at relatively low CO<sub>2</sub> increase (Δ[CO<span>2</span>] ~ 20 ppm) where the leaf area index is relatively high. Compared to GPP, the eCO<sub>2</sub> effect causing reduced transpiration water flux (normalized to leaf area) emerges only at relatively high CO<sub>2</sub> increase (Δ[CO<sub>2</sub>] >> 40 ppm), due to the high sensitivity to climate variability and thus lower signal-to-noise ratio. In general, the response to eCO<sub>2</sub> is detectable earlier for variables of the carbon cycle than the water cycle, when plant productivity is not limited by climatic constraints, and stronger in forest-dominated rather than in grass-dominated ecosystems. Our results provide a step toward when and where we expect to detect physiological CO<sub>2</sub> effects in in-situ flux measurements, how to detect them and encourage future efforts to improve the understanding and quantification of these effects in observations of terrestrial carbon and water dynamics.</p>

Data for: Tolerance of high temperature and associated effects on reproduction in euedaphic Collembola
<p>Tropical and mid-latitude terrestrial ectotherms are more vulnerable to global warming than species from high latitudes. However, thermal tolerance studies from these regions still lack soil invertebrates. We chose six euedaphic species of Collembola (of the genera <em>Onychiurus</em> and <em>Protaphorura</em>) sampled across latitudes ranging from 31°N to 64°N and first determined their upper thermal limit (UTL) by static assays. Based on their upper thermal limit, we exposed them to temperatures 32 ℃ to 36 ℃ depending on the species for 1-2 hours, which was expected to result in heat-induced injuries equivalent to 5% to 30% mortality within each species. Survivors from this series of increasing heat injuries were used to determine the time to first oviposition, and the number of eggs produced following heat exposure.</p> <p class="content">We found the upper thermal limit positively correlates to the soil temperature of the sampling site. Species have different UTL<sub>60</sub> indicating they have different tolerance to high temperatures. The species order from most heat tolerance to least was <em>O. yodai</em> > <em>P. fimata</em> > <em>P. armata</em> ≈ <em>P. tricampata</em> > <em>P. macfadyeni </em>> <em>P. pseudovanderdrifti</em>. Heat stress inflicted on survivors can prolong the time to regain reproduction in all species, and two species showed reduced egg production. The most heat-tolerant species did not have advantages over the least heat-tolerant species under a sublethal heat exposure scheme (where predicted survival was less than 30%) in terms of their recovery of reproduction. We provided evidence for a potential long-term effect of high temperature on euedaphic species of Collembola and highlighted the need for further studies on the effects of global warming on soil living organisms.</p>
Data for: The interactive effects of soil fertility and tree mycorrhizal association explain spatial variation of diversity-biomass relationships in a subtropical forest
<p><span>Observed biodiversity-ecosystem function (BEF) relationships are highly variable, particularly in natural forests. However, our understanding of the factors that generate these often contradictory patterns, especially the role of different mycorrhizal associations, is still limited. By relating tree species richness and aboveground biomass (AGB) in a fully-mapped 24-ha subtropical forest dynamics plot, we evaluated the impacts of soil fertility and tree mycorrhizal type in mediating BEF relationships at multiple spatial scales. Our results demonstrate a highly positive total richness effect on AGB for arbuscular mycorrhizal (AM) trees but a negative effect on AGB for ectomycorrhizal (EcM) trees, and their relationships were highly spatial scale dependent. However, the observed BEF relationships turned into positive at small spatial scales (i.e., 10 m and 20 m) after controlling for other confounding factors (i.e., topography, soil fertility, and AM proportion). In addition, we found significant interactions between soil fertility and species richness on AGB. Specifically, the positive effect of total species richness on AGB for major mycorrhizal types gradually weakened with increasing soil fertility, while the positive effect of EcM species richness on AM AGB gradually enhanced at small spatial scales, suggesting the observed diversity effects can be largely attributed to resource niche complementarity and the role of EcM fungi.</span></p> <p><span>Synthesis. We conclude that the variable BEF relationships among forest communities could be explained by spatial variation in abiotic environments and community mycorrhizal composition because different types of symbionts perform different nutrient uptake strategies and ability in protection from antagonists. Our findings provide novel insights into the understanding of the variation in the shape of BEF relationships in natural forests, which is critical for forest management, conservation, and restoration in a changing world.</span></p>
