Water availability influences thermal safety margins for leaves
<p>One application of plant physiological heat tolerance measurements is the assessment of vulnerability to increasing environmental temperatures under climatic change. A thermal safety margin, the difference between physiological tolerance and environmental temperature, is a common metric for the assessment of plant thermal vulnerability. However, there are biological and methodological aspects to consider when evaluating thermal vulnerability that have the potential to substantially alter assessments. Two such aspects include the leaf to air temperature relationship and the scale at which air temperature data are collected.</p> <p>We grew plants of a desert species, Myoporum montanum, in situ under water- stressed and well-watered conditions, measured their leaf temperatures and photosynthetic heat tolerance (T<sub>50</sub> threshold) every third day over 12 days in summer. Thermal safety margins were calculated based on leaf temperatures and compared to those calculated with local and regional air temperatures.</p> <p>We found that heat tolerance and the thermal vulnerability assessment of a plant changed with water status. When water was readily available, plants maintained wide leaf temperature safety margins and displayed partial-homeothermy. When cooling via transpiration was limited, increasing leaf temperature corresponded with occurrences of leaf poikilo- and megathermy, higher heat tolerance, and narrower safety margins.</p> <p>Our study shows high physiological heat thresholds are not necessarily reflective of wide safety margins, but instead can indicate a greater vulnerability and increased risk of heat stress exposure. Calculating thermal safety margins using air temperatures can also substantially alter margin widths. Where possible, the use of leaf temperatures in assessments of thermal vulnerability will lead to more meaningful vulnerability assessments. We recommend considering the source and temporal pairing of temperature measurements as well as plant water status, when measuring and interpreting plant thermal safety margins.</p>
Warm range margin of boreal bryophytes and lichens not directly limited by temperatures
<p>1. Species at their warm range margin are potentially threatened by higher temperatures, but may persist in microrefugia. Whether such microsites occur due to more suitable microclimate or due to lower biotic pressure from e.g. competitive species, is still not fully resolved.</p> <p>2. We examined whether boreal bryophytes and lichens show signs of direct climate limitation, i.e. whether they perform better in cold and/or humid microclimates at their warm range margin. We transplanted a moss, a liverwort, and a lichen to 58 boreal forest sites with different microclimates at the species' southern range margin in central Sweden. Species were grown in garden soil patches to control effects of competitive exclusion and soil quality. We followed the transplanted species over three growing seasons (2016-2018) and modelled growth and vitality for each species as a function of sub-canopy temperature, soil moisture, air humidity, and forest type. In 2018, we also recorded cover of other plants having re-colonized the garden soil patches and modelled this potential future competition with the same environmental variables plus litter.</p> <p>3. Species performance increased with warmer temperatures, which was often conditional on high soil moisture, and at sites with more conifers. Soil moisture had a positive effect, especially on the moss in the last year 2018, when the growing season was exceptionally hot and dry. The lichen was mostly affected by gastropod grazing. Recolonization of other plants was also faster at warmer and moister sites. The results indicate that competition, herbivory, shading leaf litter, and water scarcity might be more important than direct temperature for performance at the species' warm range margin.</p> <p>4. Synthesis. In a transplant experiment with three boreal understory species we did not find signs of direct temperature limitation towards the south. Forest microrefugia, i.e. habitats where these species could persist regional warming, may instead be sites with fewer competitors and enemies, and with sufficient moisture and more conifers in the overstory.</p>

Compilation of Holocene alkenone SST records along the North Pacific margins (including a new core Oki02 in the Okinawa Trough)
<p>The sediment core Oki02 (26°04' N, 125°12' E, 1,612 m water depth), located in the Okinawa Trough, is used to analyze ~100-year-resolution alkenone-based sea surface temperature (SST) values during the Holocene. Together with previously published Holocene alkenone SST paleorecords on the pathways of a set of boundary currents flowing along the North Pacific margins, e.g., the Kuroshio Current, California Current, and Alaska Current, and available foraminiferal Globigerinoides ruber Mg/Ca-based SST records over the Western Pacific Warm Pool (WPWP), we are able to investigate the centennial- to multimillennial scale variations of the North Pacific Subtropical Gyre circulation throughout the Holocene.</p>

In-depth study of the formation processes of single atmospheric particles in the southeastern margin of Tibetan Plateau
<p>The Tibetan Plateau (TP) is the most sensitive and obvious indicator of climate change in the entire Asian continent, however, real-time observations on the characteristics of full aerosol compositions are still limited within the plateau, which hinders our comprehensively understanding of the distribution characteristics and formation mechanism of aerosols in high-altitude regions. In this study, a single particle aerosol mass spectrometer was deployed to investigate the highly time resolved chemical components and atmospheric processing on the size distribution and mixing state of individual particles in the southeastern margin of the TP during the pre-monsoon season.</p>
Data from: Hedging at the rear edge: Intraspecific trait variability drives the trajectory of marginal populations in a widespread boreal tree species
<p>Rear-edge populations at the warm margin of species distribution are small, isolated and face environmental conditions at the limit of species bioclimatic envelope. Intraspecific phenotypic variation contributing to the persistence of peripheral populations is expected to become increasingly important under future climate conditions in order to avoid local extirpation where range shifts lag behind climate change velocity.</p> <p>We investigated the putative role of intraspecific phenotypic variation for the maintenance of rear-edge populations of fire-prone jack pine (<em>Pinus banksiana</em>), an obligate pyriscent boreal species. We assessed whether variation in cone serotiny is associated with the population trajectory of marginal stands located south of the boreal biome, in the temperate forest where natural wildfires are infrequent and unpredictable. To this end, we estimated stand-scale serotiny, minimal age and tree size structure in 26 jack pine stands from the rear edge (n = 17 sites) and the core (n = 9 sites) of the species' range in eastern Canada.</p> <p>On average, rear-edge jack pine populations are less serotinous albeit more variably compared to range-core populations where serotiny is more uniformly high. Rear-edge stands are generally older and display reverse J-shape tree size structure indicative of a multi-aged demographic equilibrium, whereas range-core stands are younger and show a unimodal stand structure depicting a single aging cohort generally lacking interfire recruitment. Eco-evolutionary dynamics shifts from a dependency on wildfires in range-core populations to stands that can regenerate and persist without recurrent fires at the rear edge, where stand-scale serotiny reaches values below 85%.</p> <p>Synthesis: Unlike range-core populations, rear-edge jack pine populations can locally rely on a dual life-history strategy to ensure both steady recruitment during fire-free intervals and successful postfire regeneration. This capacity to cope with infrequent and unpredictable fire regime should increase the resilience and resistance of jack pine populations as global changes alter fire dynamics of the boreal forest. More generally, unique intraspecific phenotypic variation in rear-edge populations contributes to long-term species persistence in marginal environmental conditions that might scale up with global changes. The conservation of rear-edge populations and their genetic legacy appears crucial for the resilience of species.</p>

Agricultural margins could enhance landscape connectivity for pollinating insects across the Central Valley of California, U.S.A.
<p>One of the defining features of the Anthropocene is eroding ecosystem services as a function of decreases in biodiversity and overall reductions in the abundance of once-common organisms, including many insects that play innumerable roles in natural communities and agricultural systems that support human society. It is now clear that the preservation of insects cannot rely solely on the legal protection of natural areas far removed from the densest areas of human habitation. Instead, a critical challenge moving forward is to intelligently manage areas that include intensively farmed landscapes, such as the Central Valley of California. Here we attempt to meet this challenge with a tool for modeling landscape connectivity for insects (with pollinators in particular in mind) that builds on available information including lethality of pesticides and expert opinion on insect movement. Despite the massive fragmentation of the Central Valley, we find that connectivity is possible, especially utilizing the restoration or improvement of agricultural margins which (in their summed-area) exceed natural areas. Finally, we highlight steps moving forward and the great many knowledge gaps that could be addressed in the field to improve future iterations of our modeling approach.</p>
Discrepancies between the drivers of alpha and beta plant diversity in arable field margins
<p><span>Field margins are major habitats for biodiversity conservation and ecosystem functioning in agricultural landscapes, but biotic homogenization of plant communities threatens their ecological and agronomic functions. Our objective is to assess the effects of field margin structure and long-term management of herbaceous layer over 20 years (1995–2015) on the taxonomic and functional α- and β-diversity, and the functional composition of herbaceous plant communities. In 2015, we surveyed 302 field margins in bocage landscapes of Brittany (France). Results were very similar between taxonomic and functional diversity but revealed discrepancies between α- and β-diversity. Deep ditches, mowing, and grazing increased α-diversity but did not affect β-diversity. Denser hedgerows had lower α-diversity than other field margins but contributed to β-diversity by harboring more unique sets of species or life strategies. Long-term herbicide spraying in field margins and cropping intensity in adjacent habitats did not affect α-diversity, but had more complex effects on β-diversity and selected for common weeds. Preservation of dense hedgerows and abandonment of herbicide spraying are key measures to prevent the establishment of common weeds and biotic homogenization in field margins. Above all, our study shows how important it is to go beyond α-diversity to make robust conservation and restoration decisions.</span></p>
