title: Pollination biology and breeding system analysis of Ulmus wallichiana Planchon (Ulmaceae): a rare and threatened tree species of Central and Western Himalaya

description: Understanding the constraints on sexual reproduction of a plant species
 are important for predicting stability of the species in its natural
 habitat. In the absence of such data, any conservation efforts are
 arbitrary and remain ineffective. We investigated the reproductive ecology
 and breeding system of a rare and threatened tree species of central and
 western Himalaya, Ulmus wallichiana. The phenology, floral biology and
 pollination mechanism were observed in two populations for three
 consecutive years. In addition, breeding system and pollen limitation were
 examined using hand-pollination experiments. Flowering in U. wallichiana
 begins in early March during which trees are leafless and small,
 pinkish-white flowers cover the entire tree. Pollination is accomplished
 exclusively by wind with short average distances for pollen dispersal (~50
 m). Pollination manipulation experiments showed high fruit set on
 outcrossing indicating U. wallichiana is xenogamous. However, a small
 percent of fruit set in autogamous and geitonogamous treatments indicate
 partial self-incompatibility. Fruit set augmented when pollen was
 supplemented indicating that natural fruit set in U. wallichiana is
 limited due to unavailability of adequate pollen. Thus, it can be
 concluded that reproductive success of U. wallichiana is compromised due
 to scarcity of conspecifics and partial SI may partly ensure reproductive
 assurance in the low pollen exchange environment. Present study emphasizes
 on establishment of minimum population size with optimum distance between
 trees for effective conservation interventions.

title: Datasets for Comparison of methods for estimating omnidirectional landscape connectivity

description: This repository holds the raster data and the configuration files (.ini)
 files used to create the simulated resistance grids and omnidirectional
 connectivity methods in "Comparison of methods for estimating
 omnidirectional landscape connectivity". There are reisstance grids
 for each of the two sections (simulated resistance grids and
 omnidirectional connectivity methods) and .ini files for each run with
 each method (point, wall-to-wall, and omniscape. The .ini files can be run
 in Julia computing language. Ecological connectivity is an important
 component of wildlife conservation. Omnidirectional circuit theory
 algorithms model the flow of electric current across a resistance grid
 from all directions, making them particularly useful for modeling
 connectivity of multiple or widespread species, or when source and
 destination sites are not specified, such as in the case of continuously
 distributed species. Objectives. We compared three published
 omnidirectional connectivity methods – the point-based method, the
 wall-to-wall method, and the Omniscape method.  Methods. We
 compared the three omnidirectional connectivity methods using ten
 simulated resistance grids, representing commonly encountered landscape
 features. We then used three Canada lynx (Lynx canadensis) snow-track
 datasets from Ontario, Canada to validate the ability of each method to
 detect landscape use.  Results. Current density maps generated by
 all three methods were highly correlated for most simulated landscapes,
 with the exception of uniform resistance grids. In uniform grids, without
 landscape features to guide current, each method revealed unique
 node-placement biases. All three methods produced similar connectivity
 maps for lynx, showing higher current at lynx presence locations compared
 to absence locations. The main differences between methods were not in
 their output, but in their implementation and use of computational
 resources.  Conclusions. Our findings suggest that all of the
 three currently published omnidirectional connectivity models produce
 similar current density maps and can accurately map landscape
 connectivity. We provide guidelines for selecting a method based on
 factors such as computational resources, study area, and project
 goals.

title: The influence of instrumental parameters on the particle-surface interaction measurements using colloidal probe AFM in viscous liquids

description: Understanding surface adhesion in liquids is of great significance for
 both fundamental study of suspension rheology and industry such as
 suspension mixing. However, the key factors that influence adhesion
 between non-deformable particles and surfaces in highly viscous fluids
 have not been well understood. Here we used colloidal probe atomic force
 microscope (AFM) techniques to study the adhesion forces △F in viscous
 liquids by tuning the instrumental parameters such as contact force,
 contact time, approach and retraction velocities. The data are well
 described by a theoretical model that includes the adhesion and the
 hydrodynamic forces, acting on the colloidal probe. We thereby find that
 the retraction velocity is the most significant factor that influenced the
 adhesion measurements, particularly in viscous liquids, due to the
 hydrodynamic effects. In addition, a thinner lubrication film between the
 particle and the surface would lead a higher △F, which is due to a higher
 contact force with some contact time prior to retraction.

title: Sex- and trait-specific silver-spoon effects of developmental environments, on ageing

description: AbstractThe environment organisms experience during development can have
 effects which carry over into their adult lives. These developmental
 environments may not only affect adult traits at a given point in time,
 but also how these traits change with age. Generally, stressful
 developmental environments can lead to sub-optimal adult fitness traits
 and a faster deterioration of these traits with age. But whether these
 environments affect how performance traits change with age or whether they
 affect males and females differently lacks evidence. Here, we test the
 sex-specific effects of crowding during development on life history traits
 such as lifespan, fecundity, age-dependent survival, and reproductive
 senescence, as well as flight performance traits, in the seed
 beetle-Callosobruchus maculatus. We show that although developmental
 crowding has no effect on flight performance of either sex, on male adult
 lifespan, or on female age-dependant survival, it is detrimental to female
 lifespan and fecundity, as well as female age-dependent reproduction.
 Additionally, we show that flight traits can change with age and differ
 between males and females, which may be reflective of sex-specific
 life-histories and behaviour. Our study has implications for understanding
 how developmental environments affect life history and behavioural
 strategies of both males and females.

title: Diet-induced changes in titer support a discrete response of Wolbachia-associated plastic recombination in Drosophila melanogaster

description: Plastic recombination in Drosophila melanogaster has been associated with
 a variety of extrinsic and intrinsic factors such as temperature,
 starvation, and parasite infection. The bacterial endosymbiont Wolbachia
 pipientis has also been associated with plastic recombination in D.
 melanogaster. Wolbachia infection is pervasive in arthropods and this
 infection induces a variety of phenotypes in its hosts, the strength of
 which can depend on bacterial titer. Here, we test the hypothesis that the
 magnitude of Wolbachia-associated plastic recombination in D. melanogaster
 depends on titer. To manipulate titer, we raised Wolbachia-infected and
 uninfected flies on diets that have previously been shown to increase or
 decrease Wolbachia titer relative to controls. We measured recombination
 in treated and control individuals using a standard backcrossing scheme
 with two X-linked visible markers. Our results recapitulate previous
 findings that Wolbachia infection is associated with increased
 recombination rate across the yellow-vermillion interval of the X
 chromosome. Our data show no significant effect of diet or diet by
 Wolbachia interactions on recombination, suggesting that diet-induced
 changes in Wolbachia titer have no effect on the magnitude of plastic
 recombination. These findings represent one of the first steps toward
 investigating Wolbachia-associated plastic recombination and demonstrate
 that the phenotype is a discrete response rather than a continuous one.

title: Analytical and optimization data for determination of azelastine hydrochloride and fluticasone propionate by quantitative proton NMR

description: A facile, rapid, accurate, and selective quantitative proton nuclear
 magnetic resonance (1H-qNMR) method was developed for the simultaneous
 determination of fluticasone propionate and azelastine hydrochloride in
 pharmaceutical nasal spray for the first time. The 1H-qNMR analysis of the
 studied analytes was performed using inositol as the internal standard and
 dimethyl sulfoxide-d6 (DMSO-d6) as the solvent. The quantitative selective
 proton signal of fluticasone propionate was doublet of doublet at 6.290,
 6.294, 6.316, and 6.319 ppm, while that of azelastine hydrochloride was
 doublet at 8.292 and 8.310 ppm. The internal standard (inositol) produced
 a doublet signal at 3.70 and 3.71 ppm. The method was rectilinear over the
 concentration ranges of 0.25–20.0 mg mL-1 and 0.2–15.0 mg mL-1 for
 fluticasone propionate and azelastine hydrochloride, respectively. No
 labeling or pretreatment steps were required for NMR analysis of the
 studied analytes. The proposed 1H-qNMR method was validated efficiently
 according to the International Council on Harmonisation (ICH) guidelines
 in terms of linearity, limit of detection, limit of quantification,
 accuracy, precision, specificity, and stability. Moreover, the method was
 applied to assay the analytes in their combined nasal spray formulation.
 The results ensured the linearity (r2 &gt; 0.999), precision (% RSD
 &lt; 1.5), stability, specificity, and selectivity of the developed
 method.

title: Responding to the biodiversity impacts of a megafire: a case study from south-eastern Australia’s Black Summer

description: Aim: Megafires are increasing in intensity and frequency globally. The
 impacts of megafires on biodiversity can be severe, so conservation
 managers must be able to respond rapidly to quantify their impacts,
 initiate recovery efforts and consider conservation options within and
 beyond the burned extent. We outline a framework that can be used to guide
 conservation responses to megafires, using the 1.5 million hectare
 2019/2020 megafires in Victoria, Australia, as a case study. Location:
 Victoria, Australia. Methods: Our framework uses a suite of
 decision-support tools, including species attribute databases, ~4,200
 species distribution models and a spatially-explicit conservation action
 planning tool to quantify the potential effects of megafires on
 biodiversity, and identify species-specific and landscape-scale
 conservation actions that can assist recovery. Results: Our approach
 identified 346 species in Victoria that had &gt;40% of their modelled
 habitat affected, including 45 threatened species, and 102 species with
 &gt;40% of their modelled habitat affected by high severity fire. We
 then identified 21 candidate recovery actions that are expected to assist
 the recovery of biodiversity. For relevant landscape-scale actions, we
 identified locations within and adjacent to the megafire extent that are
 expected to deliver cost-effective conservation gains. Main conclusion:
 The 2019/2020 megafires in south-eastern Australia affected the habitat of
 many species and plant communities. Our framework identified a range of
 single-species (e.g. supplementary feeding, translocation) and
 landscape-scale actions (e.g. protection of refuges, invasive species
 management) that can help biodiversity recover from megafires.
 Conservation managers will be increasingly required to rapidly identify
 conservation actions that can help species recovery from megafires,
 especially under a changing climate. Our approach brings together commonly
 used datasets (e.g. species distribution maps, trait databases, fire
 severity mapping) to help guide conservation responses and can therefore
 be used to help biodiversity recover from future megafires across the
 world.

title: Data in support of: Biomineralization of plastic waste to improve the strength of plastic-reinforced cement mortar

description: The development of methods to reuse large volumes of plastic waste is
 essential to curb the environmental impact of plastic pollution.
 Plastic-reinforced cementitious materials (PRCs), such as
 plastic-reinforced mortar (PRM), may be potential avenues to productively
 use large quantities of low-value plastic waste. However, poor bonding
 between the plastic and cement matrix reduces the strength of PRCs,
 limiting its viable applications. In this study, calcium carbonate
 biomineralization techniques were applied to coat plastic waste and
 improved the compressive strength of PRM. Two biomineralization treatments
 were examined: enzymatically induced calcium carbonate precipitation
 (EICP) and microbially induced calcium carbonate precipitation (MICP).
 MICP treatment of polyethylene terephthalate (PET) resulted in PRMs with
 compressive strengths similar to that of plastic-free mortar and higher
 than the compressive strengths of PRMs with untreated or EICP-treated PET.
 Based on the results of this study, MICP was used to treat hard-to-recycle
 types 3–7 plastic waste. No plastics investigated in this study inhibited
 the MICP process. PRM samples with 5% MICP-treated polyvinyl chloride
 (PVC) and mixed type 3–7 plastic had compressive strengths similar to
 plastic-free mortar. These results indicate that MICP treatment can
 improve PRM strength and that MICP-treated PRM shows promise as a method
 to reuse plastic waste.

title: Data from: Forecasting the cumulative effects of multiple stressors on breeding habitat for a steeply declining aerial insectivorous songbird, the olive-sided flycatcher (Contopus cooperi)

description: To halt ongoing loss in biodiversity, there is a need for landscape-level
 management recommendations that address cumulative impacts of
 anthropogenic and natural disturbances on wildlife habitat. We examined
 the cumulative effects of logging, roads, land-use change, fire, and bark
 beetle outbreaks on future habitat for olive-sided flycatcher (Contopus
 cooperi), a steeply declining aerial insectivorous songbird, in
 Canada's western boreal forest. To predict the occurrence of
 olive-sided flycatcher we developed a suite of habitat suitability models
 using point count surveys (1997–2011) spatially- and temporally-matched
 with forest inventory data. Flycatcher occurrence was positively
 associated with small (~10 ha) 10–20-year-old clearcuts, and with 10–100%
 tree mortality due to mountain pine beetle (Dendroctonus ponderosae)
 outbreaks, but we found no association with roads or distance to water. We
 used the parameter estimates from the best-fit habitat suitability models
 to inform spatially explicit state-and-transition simulation models to
 project change in habitat availability from 2020 to 2050 under six
 alternative scenarios (three management × two fire alternatives). The
 simulation models projected that the cumulative effects of land use
 conversion, forest harvesting, and fire will reduce the area of
 olive-sided flycatcher habitat by 16–18% under Business As Usual
 management scenarios and by 11–13% under scenarios that include protection
 of 30% of the land base. Scenarios limiting the size of all clearcuts to ≤
 10 ha resulted in a median habitat loss of 4–6%, but projections were
 highly variable. Under all three management alternatives, a 50% increase
 in fire frequency (expected due to climate change) exacerbated habitat
 loss. The projected losses of habitat in western boreal forest, even with
 an increase in protected areas, imply that reversing the ongoing
 population declines of olive-sided flycatcher and other migratory birds
 will require attention to forest management beyond protected
 areas. Further work should examine the effects of multiple
 stressors on the demographic mechanisms driving change in aerial
 insectivore populations, including stressors on the wintering grounds in
 South America, and should aim to adapt the design of protected areas and
 forest management policies to projected climate-driven increases in the
 size and frequency of wildfires.

title: Rapid multi-generational acclimation of coralline algal reproductive structures to ocean acidification

description: The future of coral reef ecosystems is under threat because vital
 reef-accreting species such as coralline algae are highly susceptible to
 ocean acidification. Although ocean acidification is known to reduce
 coralline algal growth rates, its direct effects on the development of
 coralline algal reproductive structures (conceptacles) is largely unknown.
 Furthermore, the long-term, multi-generational response of coralline algae
 to ocean acidification is extremely understudied. Here, we investigate how
 mean pH, pH variability and the pH regime experienced in their natural
 habitat affect coralline algal conceptacle abundance and
 size, across six generations of exposure. We show that second
 generation coralline algae exposed to ocean acidifcation treatments had
 conceptacle abundances 60% lower than those kept in present day
 conditions, suggesting that conceptacle development is initially highly
 sensitive to ocean acidification. However, this negative effect of ocean
 acidification on conceptacle abundance disappears after three generations
 of exposure. Moreover, we show that this transgenerational acclimation of
 conceptacle development is not facilitated by a trade-off with reduced
 investment in growth, as higher conceptacle abundances are associated with
 crusts with faster growth rates. These results indicate that the potential
 reproductive output of coralline algae may be sustained under future ocean
 acidification.
description: Data is from a long-term multi-generational study, in which
 coralline algae were exposed to various ocean acidification and control
 treatments for seven generations. Conceptacle abundance and size
 measurements were collected via image analysis of microscopic
 images.

title: Ecological opportunity from innnovation, not islands, drove the Anole lizard adaptive radiation

description: Islands are thought to facilitate adaptive radiation by providing release
 from competition and predation. Anole lizards are considered a classic
 example of this phenomenon: different ecological specialists (‘ecomorphs’)
 evolved in the Caribbean Greater Antilles (Cuba, Hispaniola, Jamaica, and
 Puerto Rico), resulting in convergent assemblages that are not observed in
 mainland Latin America. Yet, the role of islands in facilitating adaptive
 radiation is more often implied than directly tested, leaving uncertain
 the role of biogeography in stimulating diversification. Here, we assess
 the proposed “island effect” on anole diversification using Bayesian
 phylogenetic comparative methods that explicitly incorporate rate
 heterogeneity across the tree and demonstrate two cases of would-be false
 positives. We discovered that rates of speciation and morphological
 evolution of island and mainland anoles are equivalent, implying that
 islands provide no special context for exceptionally rapid
 diversification. Likewise, rates of evolution were equivalent between
 island anoles that arose via in situ versus dispersal-based mechanisms,
 and we found no evidence for island-specific rates of speciation or
 morphological evolution. Nonetheless, the origin of Anolis is
 characterized by a speciation pulse that slowed over time – a classic
 signature of waning ecological opportunity. Our findings cast doubt on the
 notion that islands catalyzed the anole adaptive radiation and instead
 point to a key innovation, adhesive toe pads, which facilitated the
 exploitation of many arboreal niches sparsely utilized by other iguanian
 lizards. The selective pressures responsible for arboreal niche
 diversification differ between islands and the mainland, but the tempo of
 diversification driven by these discordant processes is indistinguishable.
