Data and Models for Salt Transport in Desert, Urban, and Irrigated Landscapes

Folders contain data and models (SWAT, SWAT-MODFLOW) for analysis and modeling of salt fate and transport in urban, desert, and irrigated landscapes. Study regions include the Arkansas River Basin and the South Platte River Basin (Colorado, USA). The Education folder contains documentation of a STEM kit created at Colorado State University for guiding middle school and high school students through a 2-hour lab on salt pollution, transport, and mitigation in a mixed irrigation-desert watershed landscape.

Complex urban environments provide Apis mellifera with a richer plant forage than suburban and more rural landscapes

Growth in the global development of cities, and increasing public interest in beekeeping, has led to rises in the numbers of urban apiaries. Towns and cities can provide an excellent diet for managed bees, with a diverse range of nectar and pollen available throughout a long flowering season and are often more ecologically diverse than the surrounding rural environments. Accessible urban honeybee hives are a valuable research resource to gain insights into the diet and ecology of wild pollinators in urban settings. We used DNA metabarcoding of the rbcL and ITS2 gene regions to characterise the pollen community in Apis mellifera honey, inferring the floral diet, from 14 hives across an urban gradient around Greater Manchester, UK. We found that the proportion of urban land around a hive is significantly associated with an increase in the diversity of plants foraged, and that invasive and non-native plants appear to play a critical role in the sustenance of urban bees, alongside native plant species. The proportion of improved grassland, typical of suburban lawns and livestock farms, is significantly associated with decreases in the diversity of plant pollen found in honey samples. These findings are relevant to urban landscape developers motivated to encourage biodiversity and bee persistence, in line with global bio-food security agendas.

Multiple ecosystem service synergies and landscape-mediation of biodiversity within urban agroecosystems

Ecosystem services are essential for human well-being, especially in urban areas where 60% of the global population will live by 2030. While urban habitats have the potential to support biodiversity and ecosystem services, few studies have quantified the impact of local and landscape management across a diverse suite of services. We leverage five years of data (>5,000 observations) across a network of urban gardens to determine the drivers of biodiversity and ecosystem service trade-offs and synergies. We found multiple synergies and few trade-offs, contrasting previous assumptions that food production is at odds with biodiversity. Furthermore, we show that landscape-level natural habitat cover interacts with local management to mediate services provided by mobile animals, specifically pest control and pollination. By quantifying the factors that support a diverse suite of ecosystem services, we highlight the critical role of garden management and urban planning for optimizing biodiversity and human benefit.

Datasets and analysis for: Microclimatic buffering in forest, agricultural and urban landscapes through the lens of a grass-feeding insect

Using this dataset, we aimed to identify the microclimatic offsets that accurately represent the environment in which a small arthropod spends most of its life. As a case study, we selected grassy sites that corresponded to the microhabitat of grass-feeding insects in general, and larvae of the butterfly Pararge aegeria in particular, as this insect recently expanded its habitat use from forest (edges) to agricultural and urban environments. We tested to what extent local microclimates and microclimatic buffering capacity differed between tufts of grass in forest and in two anthropogenic (i.e. agricultural and urban) landscape settings by measuring microclimatic variables with sensors at the level of the grasses. We compared temperature, relative humidity and vapour pressure deficit (VPD) during an exceptionally warm and dry summer period with parallel data from weather stations and tested for differences between microclimatic profiles among the three landscape settings. Using this approach, our findings stress the functional implications of landscape-specific microclimatic profiles at the appropriate organism-centred scale.

Data from: Novel microsatellite markers for epiphytic bromeliad Tillandsia recurvata L., in an urban landscape in South-eastern Brazil

The authors present seven novel microsatellite markers for Tillandsia recurvata L. The genome assemble sequences of T. recurvata were obtained from NCBI (7.2Gb) (Sayers et al. 2022). The BioProject Accession and accession numbers are PRJNA701548 and SRX10089449, respectively. The microsatellite identification software Krait (0.5.2) (Du et al. 2018) was used to detect suitable microsatellites, both genome-wide and in the noncoding regions of T. recurvata. The single sequence repeats (SSRs) were refined to a minimum number of seven repeats of di-, tri-, or tetra-nucleotide repeat motifs. These sequences were further limited to SSRs of more than 100bp in length and low GC content (<50%). Krait (0.5.2) (Du et al. 2018) was also used to design the primers for the selected SSR sequences, in conjunction with the integrated Primer3 software. The criteria for primer selection included: a primer length of 18-26bp, an optimal melting temperature (Tm) of 54-59°C and GC content of <50%. These designed primers were single-plexed and amplified using the following PCR cycle: initial denaturation (95°C for 3 min), 34 cycles of 95°C for 30s, annealing for 30s (JP01-JP12: 54°C, 4873TD + 35251TD: 56°C, 19286TD: 53°C, 5044TD + 186664TD + 214633TD: 58°C), 72°C for 1 min and a final extension of 72°C for 5 mins. The authors make this information available to other researchers, to continue the investigation of epiphyte genetics.
