Wildlife gardening: an urban nexus of social and ecological relationships
<p>Data and R script codes to conduct analysis for:</p> <p>Wildlife gardening: an urban nexus of social and ecological relationships</p> <p>Laura Mumaw and Luis Mata</p> <p>https://ecoevorxiv.org/9rkhm/</p> <p><strong>Abstract</strong></p> <p>Biodiversity in urban environments continues to decline, alongside diminution of human connections with nature and community. An integrated ethic and practice of caring for one’s human and ecological community could help address these issues. Here, we describe how wildlife gardening can be such a pathway. We snapshot related social dynamics and human wellbeing benefits, highlighting a case study that reveals an array of connections and wellbeing facets from wildlife gardening, and their relationship with number of activities and time spent in the garden. We outline how positive biodiversity outcomes can be attained through habitat improvement in gardens. We describe how integration of nature and human community stewardship can work across physical and political boundaries when government and communities work collaboratively. We argue that wildlife gardening carried out in this manner can involve urban residents in crafting and enacting an intertwined ethic and practice of caring for nature and humanity.</p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p> <p> </p>

Large positive ecological changes of small urban greening actions
<p><strong>Updated data and R codes associated with our article <em>Large positive ecological changes of small urban greening actions</em>:</strong></p> <p><strong>Ecological Solutions and Evidence</strong></p> <p><strong>Abstract</strong></p> <p>The detrimental effects of human-induced environmental change on people and other species are acutely manifested in urban environments. While urban greenspaces are known to mitigate these effects and support functionally diverse ecological communities, evidence of the ecological outcomes of urban greening remains scarce. We use a longitudinal observational design to provide empirical evidence of the ecological benefits of greening actions. We show how a small greening action quickly led to large positive changes in the richness, demographic dynamics, and network structure of a depauperate insect community. We demonstrate how large ecological benefits may be derived from investing in small greening actions and how these contribute to bring indigenous species back to greenspaces where they have become rare or locally extinct. Our findings provide crucial evidence that support best practice in greenspace design and contribute to re-invigorate policies aimed at mitigating the negative impacts of urbanisation on people and other species. </p>
EAP21-0576.R1 - Implementing Community-Engaged Ecological Research in Proctor Creek, an Urban Watershed in Atlanta, GA
The Southeast Region of the U.S. Fish and Wildlife Service (USFWS) implemented community-engaged research in Proctor Creek, an urban watershed in Northwest Atlanta, Georgia, to sample for aquatic species of concern in Atlanta, Georgia’s Proctor Creek Watershed as a part of the Urban Waters Federal Partnership program. This research shifted the focus of the agency from the endangered and pristine natural spaces to a major city watershed negatively impacted by urbanization and other human influences for more than a century. Team members from USFWS, Proctor Creek Watershed residents, local students, and other stakeholders in the UWFP spent three months conducting stream surveys and participating in community-led events to build relationships and learn community priorities. The team collected data at 11 sites throughout the Proctor Creek Watershed, visually assessed each site, and collected aquatic species using dip nets, seines, and traps. We observed approximately 28 aquatic species, including 13 unique fish species, and eight macroinvertebrate species, including two unique crayfish species. We also observed varying degrees of ecological health throughout the watershed. Native aquatic animal species were found at all stream sites, no matter the condition of the stream. Through creating training resources and disseminating data among team members for future sampling, the team established pathways to keep natural resource stewardship sustainable outside of direct federal involvement. Through engaging in community-engaged research to achieve the mission of the agency, the USFWS Proctor Creek watershed survey helped shift the paradigm of how government agencies can connect their mission statements to the ever-changing complex needs of the American public.
Ecohydrological monitoring of urban ecological infrastructure at the Arizona State University Tempe Campus (Tempe, Arizona)
Urban Ecological Infrastructure (UEI) are urban ecological structures whose ecological functions are increasingly being used to deliver key urban services and address urban sustainability challenges. The growing use of UEI to address urban sustainability challenges can bring together teams of urban researchers and practitioners to co-produce UEI design, monitoring and maintenance. However, this co-production process received little attention in the literature, and has not been studied in the Phoenix Metro Area. This study examined several components of a co-produced design process and related project outcomes associated with a small-scale UEI project – bioretention basins installed at the Arizona State University (ASU) Orange Mall and Student Pavilion in Tempe, AZ. We explored the design process associated with the collaborative development of an ecohydrological monitoring protocol for assessment of post-construction performance of this UEI system. This co-production process involved both CAP LTER researchers and practitioners, designers, and managers at ASU and associated third-party consultants involved in site design and management. Together, these researchers and practitioners co-produced a suite of ecohydrological metrics to monitor the performance of the bioretention basins at Orange Mall. Specifically, this protocol evaluated the performance of the UEI system with regards to two of it’s key design goals: storm water capture and storm water quality improvement. The ecohydrological data produced by the implementation of this monitoring protocol are presented here. Monitoring equipment were installed throughout the site in June and July 2018. Site monitoring and data collection began in August 2018, and continued through Feb 2019.
Growing in the city: urban evolutionary ecology of avian growth rates.
<p>Rapid environmental change driven by urbanisation offers a unique insight into the adaptive potential of wildlife as it can induce distinct selective pressures on urban dwelling organisms. Despite mounting evidence for urban-driven phenotypic differentiation across taxa, knowledge of the impact of urbanisation on vertebrate developmental rates and subsequent survival is very limited. Importantly, the role of selection on urban-driven body mass divergence in juvenile organisms remains poorly understood. We studied nestling development in a gradient of urbanisation set in Warsaw, Poland, in two nestbox breeding passerine species: great tits (<i>Parus major</i>) and blue tits (<i>Cyanistes caeruleus</i>). Each nestbox in the study system was assessed for surrounding percentage of Impervious Surface Area (ISA). Within these nestboxes, weight measurements of individual nestlings were collected during three breeding seasons and at regular intervals after hatching. Although asymptotic mass and growth rate were not directly affected by ISA in a subset of frequently measured nestlings, the age of fastest growth (inflection point) was delayed in blue tit nests surrounded by greater ISA. Across the entire dataset, nestling body mass was negatively affected by increasing ISA at days 5 and 10 after hatching for great tits, and at days 10 and 15 for blue tits, respectively. Concomitantly, offspring survival at days 5 and 10 decreased with increasing ISA for both species. An analysis of selection differentials performed for two contrasting levels of imperviousness (low and high ISA) revealed a significant positive association between mass at day 2 and survival at fledging. Importantly, the strength of selection for heavier nestlings at hatching was greater for great tits in the more transformed, high ISA environment. This study confirms the considerable impact of imperviousness -a proxy for urbanisation level- on offspring development, body mass and survival, and highlights increased selection on avian birth weight in a high ISA environment.</p>
Reassessing the climate mitigation potential of Chinese ecological restoration: the undiscovered potential of urban areas
<p>The dataset includes urban climate mitigation benefit data for all 371 cities and 1,721 clusters in China, as well as aggregate data of different ecological restoration projects and climate backgrounds. Combining multi-source high-resolution remote sensing data sets and the reanalysis dataset, the absolute value standard deviation method of multiple linear regression is used to extract the largest dominant factor (pixel-by-pixel calculation) of daytime surface temperature in each city except NDVI (as a greening indicator). Then, the time trends of surface temperature, NDVI, and dominant factors were calculated based on the Theil-Sen Median slope estimation method. Finally, based on the linear statistical relationship of the three indicators, the surface temperature trend under the no-greening scenario was constructed, and the difference between the simulated and observed surface temperature trends was used to characterize the urban climate mitigation benefits of the ecological restoration project.

Nest-boxes alter the reproductive ecology of urban cavity-nesters in a species-dependent way
<p><span>Human-provided nesting shelters such as nest-boxes mitigate the shortage of natural breeding sites. Since artificial nests are not where animals evolved and optimised their reproductive performance, it remains inconclusive if these are adequate substitutes, ensuring equivalent fitness returns while breeding. In particular, most knowledge on the ecology of cavity-nesting birds comes from nest-box populations, but no study has directly compared fitness consequences of breeding inside nest-boxes in relation to natural cavities in cities. We directly compare the reproductive performance, life-history trait variation and fitness consequences for two small passerines, blue and great tits, breeding in nest-boxes as opposed to natural cavities in an urban deciduous forest. We use a quasi-experimental setting to comprehend the conservation potential of these artificial cavities and to support/question generalisations stemming from nest-box studies. We show that the effects of cavity type vary between species: in blue tits, fitness proxies were negatively affected by nest-boxes (lower fledging success and fledgling numbers, longer time spent in the nest and later fledging date relative to natural cavities), while in great tits, the fitness proxies were unaffected by cavity type. Importantly, we detected accelerated incubation in both species breeding in nest-boxes. No differences in pre-hatching traits (lay date, clutch size, hatching rates) between cavity types suggest that the fitness deterioration occurred because of post-hatching effects. We highlight the ecological importance of old-growth tree stands, providing natural cavities for city-breeding animals and the need for quantifying alterations of reproductive ecology in other taxa using human-provided nests. Due to the detected cavity type-dependent variation in reproductive performance, we support the criticism regarding the unconditional extrapolation of evolutionary and ecological interpretations of nest-box studies to general populations.</span></p>
