title: Cascading effects of algal warming in a freshwater community

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;1. Much of our research on the effects of ongoing climate warming on ecological communities is focused on how temperature affects resource quantity. However, resource quality is also affected by warming, and changes in resource quality can have meaningful effects on the productivity of higher trophic levels.&lt;/p&gt; &lt;p&gt;2. Aquatic communities in particular are likely to affected by temperature-mediated shifts in resource quality because the nutritional value of algae is highly sensitive to temperature. For example, the production of healthful omega-3 polyunsaturated fatty acids (n-3 PUFA) by algae often decreases with warming.&lt;/p&gt; &lt;p&gt;3. Documented decreases in algal PUFAs with warming have led to the hypothesis that global warming should lead to an overall decrease in productivity in aquatic communities. However, this hypothesis: a) potentially oversimplifies the relationship between algal PUFAs and temperature, and b) assumes that the nutritional requirements of consumers are not affected by temperature warming. Here we test these assumptions using a freshwater community (Scenedesmus algae, Daphnia zooplankton, Chaoborus insects).&lt;/p&gt; &lt;p&gt;4. We found that total algal PUFAs per unit cell size increased, but cell size decreased with warming, resulting no net effect of warming on PUFA per algal cell. We also found a negative relationship between algal neutral lipids and temperature. Daphnia fed 12˚C-reared algae maintained higher population sizes than those fed 20˚C or 28˚C-reared algae, but the effect of algal food type diminished with increasing Daphnia rearing temperature. The indirect effects of cold-reared algae on the growth rate of Chaoborus predators were minor.&lt;/p&gt; &lt;p&gt;5. These data highlight the importance of investigating the effects of temperature on both resource quality and on the nutritional needs of consumers. Our results suggest that at warmer temperatures, consumer nutritional requirements may be reduced. We caution against broad claims that the negative relationship between some algal PUFAs and temperature should result in overall declines in aquatic productivity with ongoing climate warming.&lt;/p&gt;

title: Evaluating Landscape Metrics as Predictors of Area Burned by Wildfire and Monitoring Landscape Level Change in the Interior Douglas-Fir Zone in British Columbia

description: The Interior Douglas-fir zone of British Columbia’s Cariboo Region evolved alongside wildfire through millennia of repeat exposure. Resulting from these interactions were fire adapted species and landscape configurations that supported low to moderate severity wildfires. Removing the dominant disturbance agent of these dry forest ecosystems through systematic fire suppression has resulted in unforeseen repercussions. Presently, forests of the Interior Douglas-fir zone hold the potential for higher severity wildfire posing an increased threat to human life. This project was conducted to evaluate landscape metrics as predictors of area burned within the Interior Douglas-fir zone of the Cariboo Region. Six landscape metrics pertaining to the composition and configuration of landscape patches were calculated within 2500 hectare sampling cells. Additional work was conducted to quantify changing landscape metrics between 1985 and 2016. Key to this report are annual land cover maps generated following the Virtual Land Cover Engine framework applied to Landsat-5 TM and Landsat-7 ETM+ imagery. Results indicate that none of the landscape metrics involved in this project are effective predictors of area burned. Trend analysis from 1985 to 2016 concluded that several landscape metrics exhibited significant monotonic trends. The number of patches, landscape shape index, and Shannon’s diversity index were found to be increasing while mean patch area, and proportion of like adjacency were found to be decreasing. Additionally, no significant change in the area burned was observed. These results suggest that another agent, likely timber harvesting and climate change, are driving trends in landscape metrics. Overall, landscapes are becoming more heterogeneous. This does not necessarily translate to decreasing wildfire severity or size.

title: Changes in arthropod community but not plant quality benefit a specialist herbivore on plants under reduced water availability

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p style="margin-bottom:13px;"&gt;Plants growing under reduced water availability can affect insect herbivores differently, in some instances benefitting them. However, the forces mediating these positive impacts remain mostly unclear. To identify how water availability impacts plant quality and multitrophic interactions, we conducted manipulative field studies with two populations of the specialist herbivore &lt;i&gt;Pieris rapae&lt;/i&gt;, and its host plant, &lt;i&gt;Rorippa indica&lt;/i&gt;. We found that &lt;i&gt;P. rapae &lt;/i&gt;larvae experienced higher survival on &lt;i&gt;R. indica&lt;/i&gt; growing under low water availability compared with plants grown under high water availability. Higher survival of eggs and larvae was related to the reduced abundance of other herbivores and natural enemies. Water availability had differential impacts on other members of the herbivore community by altering plant quality. Low water availability decreased the quality of &lt;i&gt;R. indica&lt;/i&gt; to most herbivores, as indicated by reduced abundance in the field and decreased relative growth rate in laboratory feeding assays. In contrast, &lt;i&gt;P. rapae &lt;/i&gt;larval performance was not affected by sympatric &lt;i&gt;R. indica &lt;/i&gt;grown under different water availability. These results indicate that local &lt;i&gt;P. rapae&lt;/i&gt; populations possess physiological adaptations to overcome fluctuations in host quality. Our findings illustrate that reduced water availability is beneficial to a specialist herbivore but detrimental to most other herbivores. Our work highlights the complex effects of the arthropod communities associated with plants in determining the impacts of water availability on insect herbivores.&lt;/p&gt;

title: SpiCE: Speech in Cantonese and English

description: This is the Speech in Cantonese and English (SpiCE) corpus. SpiCE is an audio corpus of conversational Cantonese-English bilingual speech recorded in Vancouver, Canada during 2018-2020. The corpus includes high-quality recordings of 34 early bilinguals in both English and Cantonese. Participants completed a sentence reading task, storyboard narration, and conversational interview in each language. These different speech tasks are available in a single audio file for each language for each talker. A Praat textgrid file accompanies each audio file. The textgrids provide hand-corrected orthographic transcription and phoneme-level forced-alignment in Cantonese and English. As an open-access language resource, SpiCE will promote bilingualism research for a typologically distinct pair of languages, of which Cantonese remains understudied despite there being millions of speakers around the world. The SpiCE corpus is especially well-suited for phonetic research on conversational speech, and enables researchers to study cross-language within-speaker phenomena for a diverse group of early Cantonese-English bilinguals. These are areas with few existing high-quality resources. Corpus documentation is available at: &lt;a href="https://spice-corpus.readthedocs.io/"&gt;https://spice-corpus.readthedocs.io/&lt;/a&gt;.

title: Data from: Thermal tolerances and species interactions determine the elevational distributions of insects

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;&lt;b&gt;Aim:&lt;/b&gt; While physiological limits to thermal extremes are often thought to determine the abundance and geographic distribution of species, more recent evidence suggests that species interactions may be equally important. Moreover, the relative importance of these constraints may shift with changing abiotic conditions, such as climate change. Here, we explore the relative importance of physiological tolerances to heat and species interactions in determining the distribution of insects along two elevational gradients. The gradients contrast in precipitation but not temperature, allowing us to separate these two climatic factors.&lt;/p&gt; &lt;p&gt;&lt;b&gt;Location:&lt;/b&gt; Montane rainforest in Costa Rica.&lt;/p&gt; &lt;p&gt;&lt;b&gt;Time period:&lt;/b&gt; 2015-2016.&lt;/p&gt; &lt;p&gt;&lt;b&gt;Major taxa studied:&lt;/b&gt; Bromeliad-dwelling aquatic insect larvae.&lt;/p&gt; &lt;p&gt;&lt;b&gt;Methods:&lt;/b&gt; We estimated the elevation preferences of five insect taxa by surveying 170 bromeliads along the moist Atlantic and the dry Pacific slopes of Monteverde, and experimentally determined their critical thermal maxima (CT&lt;sub&gt;max&lt;/sub&gt;). We determined if species-specific heat tolerances predict their elevation preferences, using Deming regressions, and tested if potential predators mediated elevation effects on species distributions, using structural equation models.&lt;/p&gt; &lt;p&gt;&lt;b&gt;Results:&lt;/b&gt; On the moist Atlantic slope, heat tolerances of insects explained their elevational distributions: taxa with high heat tolerances preferred low elevations where conditions are warmest, while taxa with low heat tolerances preferred high elevations where it is coldest. By contrast, on the drier Pacific slope, the elevational abundance pattern of many insects reflected negative interactions from cranefly larvae. These larvae are known to become predatory under drought conditions and were disproportionally abundant at low elevations on the Pacific slope.&lt;/p&gt; &lt;p&gt;&lt;b&gt;Main conclusions: &lt;/b&gt;We show that under drought, indirect effects mediated by species interactions can override any direct physiological effects of environmental conditions on insect distributions. The relative importance of limits to physiological tolerance and species interactions thus depends on environmental context, an important insight given that environmental conditions are expected to shift with climate change.&lt;/p&gt;

title: Sequence alignments of Corallicolids, apicomplexan symbionts of coral

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p class="BodyA" style="border:none;"&gt;Corals (Metazoa; Cnidaria; Anthozoa) have recently been shown to play host to a widespread and diverse group of intracellular symbionts of the phylum Apicomplexa. These symbionts, colloquially called ‘corallicolids’, are mostly known through molecular analyses, and no formal taxonomy has been proposed. Another apicomplexan, &lt;i&gt;Gemmocystis cylindrus&lt;/i&gt; (described from the coral &lt;i&gt;Dendrogyra cylindrus&lt;/i&gt;), may be related to corallicolids, but lacks molecular data. Here, we isolate and describe motile trophozoite (feeding) corallicolids cells using microscopic (light, SEM, and TEM) and molecular phylogenetic analysis to provide the basis for a formal description. Phylogenetic analyses using nuclear and plastid rRNA operons, and three mitochondrial protein sequences derived from single-cell transcriptomes, all confirm that these organisms fall into a discrete deep-branching clade within the Apicomplexa not closely related to any known species or major subgroup. As a result, we assign this clade to a new order, Corallicolida ord. nov., and family, Corallicolidae fam. nov. We describe a type species, &lt;i&gt;Corallicola aquarius&lt;/i&gt; gen. nov. sp. nov. from its &lt;i&gt;Rhodactis &lt;/i&gt;sp.&lt;i&gt; &lt;/i&gt;host, and also describe a second species, &lt;i&gt;Anthozoaphila gnarlus&lt;/i&gt; gen. nov. sp. nov., from the coral host &lt;i&gt;Madracis mirabilis&lt;/i&gt;. Finally, we propose reassigning the incertae sedis taxon &lt;i&gt;G. cylindrus&lt;/i&gt; from the order Agamococcidiorida to the Corallicolida, based on similarities in morphology and host localization to that of the corallicolids.&lt;/p&gt;

title: Data from: Estimating encounter location distributions from animal tracking data

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;1. Ecologists have long been interested in linking individual behavior with higher-level processes. For motile species, this 'upscaling' is governed by how well any given movement strategy maximizes encounters with positive factors, and minimizes encounters with negative factors. Despite the importance of encounter events for a broad range of ecological processes, encounter theory has not kept pace with developments in animal tracking or movement modeling. Furthermore, existing work has focused primarily on the relationship between animal movement and encounter &lt;em&gt;rates&lt;/em&gt; while the relationship between individual movement and the spatial &lt;em&gt;locations&lt;/em&gt; of encounter events in the environment has remained conspicuously understudied.&lt;/p&gt; &lt;p&gt;2. Here, we bridge this gap by introducing a method for describing the long-term encounter location probabilities for movement within home ranges, termed the conditional distribution of encounters (CDE). We then derive this distribution, as well as confidence intervals, implement its statistical estimator into open source software, and demonstrate the broad ecological relevance of this distribution.&lt;/p&gt; &lt;p&gt;3. We first use simulated data to show how our estimator provides asymptotically consistent estimates. We then demonstrate the general utility of this method for three simulation-based scenarios that occur routinely in biological systems: i) a population of individuals with home ranges that overlap with neighbors; ii) a pair of individuals with a hard territorial border between their home ranges; and iii) a predator with a large home range that encompassed the home ranges of multiple prey individuals. Using GPS data from white-faced capuchins (&lt;em&gt;Cebus capucinus&lt;/em&gt;) tracked on Barro Colorado Island, Panama, and sleepy lizards (&lt;em&gt;Tiliqua rugosa&lt;/em&gt;) tracked in Bundey, South Australia, we then show how the CDE can be used to estimate the locations of territorial borders, identify key resources, quantify the potential for competitive or predatory interactions, and/or identify any changes in behaviour that directly result from location-specific encounter probability.&lt;/p&gt; &lt;p&gt;4. The CDE enables researchers to better understand the dynamics of populations of interacting individuals. Notably, the general estimation framework developed in this work builds straightforwardly off of home range estimation and requires no specialised data collection protocols. This method is now openly available via the ctmm R package.&lt;/p&gt;

title: Forest management impacts on greenhouse gas fluxes from riparian soils along headwater streams

description: This data supports the 2021 publication "Forest management impacts on greenhouse gas fluxes from riparian soils along headwater streams" in Ecosystems. Abstract: Increasing concentrations of atmospheric greenhouse gases (GHGs; CO2, CH4, N2O) causes climate change. Depending on the conditions, soils have the potential to store carbon or to be a source of GHGs to the atmosphere. Riparian soils in particular have high potential to store carbon, but also to be sources of CH4 and N2O. Headwater streams make up a large proportion of stream length in a drainage network, and their riparian zones have valuable ecosystem functions. In parallel, the riparian zones of headwater streams are particularly vulnerable to forest harvest. Studies of GHG fluxes from these unique ecosystems remain limited. Our objective was to quantify the effects of forestry practices and groundwater discharge (DIS) areas on GHG emissions from riparian forest soils in coastal British Columbia. We compared nine sites with three different forest management protocols: 1) harvesting with a riparian buffer, 2) no buffer, and 3) reference sites without harvesting. We measured gas fluxes, soil temperature, soil moisture and depth to the groundwater table alongside headwater streams monthly over one growing season. We found that CH4 uptake rates were 65% lower at the no buffer sites, and N2O emission rates were 52% lower at the no buffer sites, when compared to the reference sites. Additionally, CH4 uptake was 54% lower at DIS areas than in non-DIS areas. The results of our research help inform forest management by demonstrating that maintaining riparian buffers can be effective in protecting the ecosystem functions contributing to soil GHG fluxes.

title: Data from: Evidence for ephemeral ring species formation during the diversification history of Western Fence Lizards (Sceloporus occidentalis)

description: &lt;b&gt;Abstract&lt;/b&gt;&lt;br/&gt;&lt;p&gt;Divergence is often ephemeral, and populations that diverge in response to regional topographic and climatic factors may not remain reproductively isolated when they come into secondary contact. We investigated the geographic structure and evolutionary history of population divergence within Sceloporus occidentalis (Western Fence Lizards), a habitat generalist with a broad distribution that spans the major biogeographic regions of Western North America. We used double digest RAD sequencing to infer population structure, phylogeny, and demography. Population genetic structure is hierarchical and geographically structured with evidence for gene flow between biogeographic regions. Consistent with the isolation-expansion model of divergence during Quaternary glacial-interglacial cycles, gene flow and secondary contact are supported as important processes explaining the demographic histories of populations. Although populations may have diverged as they spread northward in a ring-like manner around the Sierra Nevada and southern Cascade Ranges, there is strong evidence for gene flow among populations at the northern terminus of the ring. We propose the concept of an “ephemeral ring species” and contrast S. occidentalis with the classic North American ring species, Ensatina eschscholtzii. Contrary to expectations of lower genetic diversity at northern latitudes following post-Quaternary-glaciation expansion, the ephemeral nature of divergence in S. occidentalis has produced centers of high genetic diversity for different reasons in the south (long-term stability) versus the north (secondary contact).&lt;/p&gt;
