title: A field boundary dataset for the Canadian Prairies derived from Sentinel-2 imagery using the Segment Anything Model

description: Content:
 This dataset contains delineated agricultural field boundary polygons for the Canadian Prairies covering Alberta, Saskatchewan, and Manitoba. The field boundaries were derived from automated image segmentation applied to satellite imagery and represent individual crop field extents across agricultural regions. Each polygon includes geometric properties and identifiers that link to spatial regions (RMs). The dataset comprises 457 shapefiles encompassing 656,082 field polygons across the three provinces, providing a comprehensive geospatial representation of agricultural land parcels suitable for agricultural monitoring, land management, and regional analysis applications.

Location:
 The data were collected across the Canadian Prairies, including Alberta, Saskatchewan, and Manitoba, covering major agricultural regions between approximately 49°–55° N latitude and 96°–114° W longitude. The processed dataset is stored and maintained at the authors’ institutional affiliation. 

Structure :
 The dataset is organized as a structured repository containing vector data representing agricultural field boundaries across the Canadian Prairies. The repository consists of the following hierarchy:
 /Field Boundaries/
 ├── /Alberta_Shapefiles/ (zipped field boundary shapefiles for Alberta)
 ├── /Saskatchewan_Shapefiles/ (zipped field boundary shapefiles for Saskatchewan)
 ├── /Manitoba_Shapefiles/ (zipped field boundary shapefiles for Manitoba)
 ├── /geoparquet_AB/ (Geoparquet maps for Alberta)
 ├── /geoparquet_SK/ (Geoparquet maps for Saskatchewan)
 └── /geoparquet_MB/ (Geoparquet maps for Manitoba)
 /Metadata/ (metadata files describing the dataset)
 
 Each field boundary shapefile is packaged as a zip file containing polygon geometries in ESRI Shapefile format with standard geometry files (.shp, .shx, .dbf, .prj) and is projected in a consistent coordinate reference system suitable for regional-scale analysis. Additionally, the dataset includes Geoparquet format files for each province, providing a modern, efficient alternative format for the same field boundaries. The boundary data represent delineated field boundaries derived from automated image segmentation.

Format:
 Field boundary polygons are provided in two formats: 
 1. ESRI Shapefile format (as zip archives) with associated geometry files and projection information
 2. Geoparquet format for efficient storage and processing

title: Data from: Resource-driven changes to host population stability alter the evolution of virulence and transmission

description: What drives the evolution of parasite life history traits? Recent studies
 suggest that feedbacks between within-host and between-host processes can
 provide key insight into both disease dynamics and parasite evolution.
 Still, it remains difficult to understand how to mechanistically connect
 these cross-scale feedbacks, particularly under non-equilibrium
 conditions; many natural host populations inherently fluctuate and
 parasites themselves can strongly alter the stability of host populations.
 Here, we develop a general model framework that mechanistically links
 resources to parasite evolution across a gradient of stable and unstable
 conditions. First, we dynamically link resources and between-host (host
 density, stability, transmission) processes to virulence evolution. Then,
 we consider a ‘nested’ model where population-level processes
 (transmission and virulence) depend on resource-driven changes to
 individual-level (within-host) processes (energetics, immune function,
 parasite production). Contrary to ‘non-nested’ model predictions, the
 nested model reveals complex effects of host population dynamics on
 parasite evolution, including regions of evolutionary bistability, where
 evolution can push parasites toward strongly or weakly stabilizing
 strategies. This bistability results from tension between resource-driven
 changes to host density, host immune function, and parasite production.
 Together, these results highlight how cross-scale feedbacks can provide
 key insights into the structuring role of parasites and parasite
 evolution.

title: Data from: Limited pollen dispersal, small genetic neighborhoods, and biparental inbreeding in Vallisneria americana Michx. (Hydrocharitaceae)

description: Premise of the study: Pollen dispersal is a key process that influences
 ecological and evolutionary dynamics of plant populations by facilitating
 sexual reproduction and gene flow. Habitat loss and fragmentation have the
 potential to reduce pollen dispersal within and among habitat patches. We
 assessed aquatic pollen dispersal and mating system characteristics in
 Vallisneria americana -- a water-pollinated plant with a distribution that
 has been reduced from historic levels. Methods: We examined pollen
 neighborhood size, biparental inbreeding, and pollen dispersal, based on
 seed paternity using the indirect paternity method KinDist, from samples
 of 18 - 39 mothers and 14 - 20 progeny per mother from 3 sites across 2
 years. Key Results: On average, fruits contained seeds sired by 7 fathers.
 We found significant biparental inbreeding and limited pollen dispersal
 distances (0.8 - 4.34 m). However, in a number of cases correlated
 paternity did not decline with distance and dispersal could not be
 reliably estimated. Conclusions: Frequent pollen dispersal is not expected
 among patches, and even within patches gene flow via pollen will be
 limited. Limited pollen dispersal establishes genetic neighborhoods which,
 unless overcome by seed and propagule dispersal, will lead to genetic
 differentiation even in a continuous population. Unless loss and
 fragmentation drive populations to extreme sex bias, local pollen
 dispersal is likely to be unaffected by habitat loss and fragmentation per
 se because the spatial scale of patch isolation already exceeds pollen
 dispersal distances. Therefore, managing specifically for pollen
 connectivity is only relevant over very short distances.

title: Data from: Phenological responses to multiple environmental drivers under climate change: insights from a long-term observational study and a manipulative field experiment

description: • Climate change has induced pronounced shifts in the reproductive
 phenology of plants, yet we know little about which environmental factors
 contribute to interspecific variation in responses and their effects on
 fitness. • We integrate data from a 43-year record of first flowering for
 six species in subalpine Colorado meadows with a 3-year snow manipulation
 experiment on the perennial forb Boechera stricta (Brassicaceae) from the
 same site. We analyze shifts in the onset of flowering in relation to
 environmental drivers known to influence phenology: the timing of
 snowmelt, the accumulation of growing degree days, and photoperiod.•
 Variation in responses to climate change depended on the sequence in which
 species flowered, with early-flowering species reproducing faster, at a
 lower heat sum, and under increasingly disparate photoperiods relative to
 later-flowering species. Early snow removal treatments confirm that the
 timing of snowmelt governs observed trends in flowering phenology of B.
 stricta and that climate change can reduce the probability of flowering,
 thereby depressing fitness. • Our findings suggest that climate change is
 decoupling historical combinations of photoperiod and temperature and
 outpacing phenological changes for our focal species. Accurate predictions
 of biological responses to climate change require a thorough understanding
 of the factors driving shifts in phenology.

title: Data from: Evolution and reciprocal origins in Mediterranean ferns: the Asplenium obovatum and A. adiantum-nigrum complexes

description: Asplenium is estimated to be the largest fern genus, and is very prone to
 polyploidy and hybridization. We investigated the phylogenetic
 relationships of two geographically-restricted complexes in the
 Mediterranean Basin, and searched for evidence of multiple and/or
 reciprocal origins of the allopolyploids. The Asplenium obovatum and A.
 adiantum-nigrum complexes include a total of five diploid and four
 polyploid taxa, and are linked by the tetraploid A. balearicum. We
 collected 36 new samples representing all nine taxa, from which we
 amplified 5 chloroplast regions. We also included sequences from GenBank
 and performed ML and BI analyses to identify multiple and reciprocal
 origins. We conducted a larger molecular dating analysis to assess
 relationships with the rest of Asplenium and estimate divergence times.
 This matrix included 137 species of Asplenium and three outgroups,
 including sequences previously published. All sequences of allotetraploids
 A. adiantum-nigrum and A. balearicum grouped with A. onopteris, with no
 sign of reciprocal parentage, but possible evidence of multiple origins.
 The tetraploids A. foreziense and A. billotii grouped with both respective
 parents, indicating probable multiple and reciprocal origins. The best
 supported case of reciprocal parentage is A. foreziense. In the larger
 analysis, the species studied resolve in two different clades that
 correspond to the two complexes, and the groups are not closely related,
 with a conservative estimate of 45.43 Mya for their divergence. There is
 evidence of multiple origins of all four allopolyploids, though only with
 strong support for one, and of reciprocal origins for two of the four
 allopolyploids, though again only one is well supported. A. balearicum
 represents a hybridization event between members of clades whose ancestors
 diverged roughly 45 million years ago, making this divergence one of the
 oldest to have descendants later produce hybrid offspring.

title: Data from: Hydrogen sensing enhancement of zinc oxide nanorods via voltage biasing

description: The capability of zinc oxide (ZnO) as hydrogen sensing elements has been
 pushed to its limits. Different methods have been explored to extend its
 sensing capability. In this paper, we report a novel approach which
 significantly improves the hydrogen sensing capability of zinc oxide by
 applying a bias voltage to ZnO nanorods as the sensing elements. Zinc
 oxide in the form of aligned nanorods were first synthesized on an
 Au-coated Si(111) substrate using a facile method via the
 galvanic-assisted hydrothermal process. The sensing performance of the
 zinc oxide nanorods was investigated in respond to the applied biasing
 voltage. It was found that the sensitivity, response time as well as
 detection limit of the ZnO sensing elements were dramatically improved
 with increasing bias voltage. A 100% increment in sensing response was
 achieved for detection of 2000 ppm hydrogen gas when the bias voltage was
 increased from -2 V to -6 V with 70% reduction in response and recovery
 times. This remarkable sensing performance is attributed to the reaction
 of hydrogen with chemisorbed oxygen ions on the surface of the ZnO
 nanorods that served as the electron donors to increase the sensor
 conductance. Higher reverse bias voltages sweeps the electrons faster
 across the electrodes. This shortened the response time and, at the same
 time, depleted the electrons in the sensor elements and weaken oxygen
 adsorption. The oxygen ions could then be readily removed by hydrogen,
 leading to higher sensitivity of the sensors. This, therefore, envisage a
 way for high-speed hydrogen gas sensing with high detection sensitivities.

title: Data from: Isotopic and dietary niches as indicators for resource partitioning in the gleaner bats M. bechsteinii, M. nattereri, and P. auritus

description: The n-dimensional ecological niche summarizes all living requirements of a
 species. According to the competition and niche theory, co-occurring
 species have to differ in at least one dimension to live in stable
 coexistence. Measuring the overall ecological niche within natural
 ecosystems is probably impossible but methods that describe several
 dimensions at once like the isotopic niche are good approximations.
 However, the impact of each factor contributing to the isotopic niche
 might be difficult to estimate. The dietary niche, as one part of the
 isotopic niche, can be examined with high resolution using molecular
 techniques. In this study we aimed to improve our understanding of species
 coexistence. We outlined the importance of the isotopic and dietary niches
 in the context of resource partitioning using the bat species M.
 bechsteinii, M. nattereri, and P. auritus of the gleaner guild as
 examples. The dietary and isotopic niches were estimated with stable
 isotope analysis and molecular fecal analysis. We tested (i) how distinct
 the occupied dietary niches of members of the same guild are and (ii) how
 similar the dietary and isotopic niches are to each other. While the
 inter-specific overlap was high for the dietary niche, no overlap could be
 observed for the isotopic niche. In general, the isotopic niche can
 describe a more complete picture of the ecological niche, while the
 dietary niche provides highly detailed information. The combination of
 both niches might advance our understanding of stable species
 coexistences.
