“…However, traditional multivariate analysis methods, such as MANOVA, make stringent assumptions which are untenable for most ecological datasets (McArdle and Anderson 2001). More recently, permutational analysis of variance (PERMANOVA; Anderson 2001) has been used to compare urban forests composition across geographic and urbanization gradients (Blood et al 2016, Yang et al 2017, as well as to test for differences among neighborhood species compositions within an urban region (Avolio et al 2018). Thus, non-parametric methods are preferable.…”

“…Also, further information is needed on how the increasing use of available plot-level data in both rural and urban forests can be used to address questions regarding ecological disturbance, functionality, and homogenization (Staudhammer et al 2015, Speak et al 2018. Such studies of tree and plant diversity among and within forested ecosystems can help characterize differences and similarities in communities across different disturbance regimes and scales (Yang et al 2017).…”

“…Similarly, over the last decade, local-level data are being increasingly collected in urban forests across the world using standardized protocols, allowing researchers to address regional-, national-, and continental-level applied urban ecology questions, such as those comparing species diversity and distributions (Kendal et al 2014, Staudhammer et al 2015, Jenerette et al 2016, Yang et al 2017, Speak et al 2018).

“…But a study across climate and land use revealed that these targets are rarely met at the species level (Kendal et al 2014). Evidence of such urban homogenization has been reported across major cities in the United States and China, with hypothesized continental-scale consequences, including effects on carbon sequestration, microclimate, and other ecosystem properties (Groffman et al 2014, Yang et al 2017.

Assessing methods for comparing species diversity from disparate data sources: the case of urban and peri‐urban forests

Multi-scale forest inventory and monitoring data are increasingly being used in studies assessing forest diversity, structure, disturbance, and carbon dynamics. Also, local-level urban forest inventories are providing plot data and protocols to study tree diversity and ecosystem services in urban forests worldwide. But, differences in the sampling methods underlying these disparate protocols and data sources is a non-trivial concern in formulating comparative analyses. We assess commonly used methods for comparing tree diversity in peri-urban and urban forests when available data have different sample sizes, plot sizes, and sampling intensities. We present methods for appropriately evaluating species richness, as well as methods for comparing species distributions via community data matrices. Using permanent plot data from the southeastern United States, we present a case study comparing urban and peri-urban forests along a north-south gradient, and assessing species richness and the ecological homogenization hypothesis. Our findings indicate that comparisons of tree species richness among communities, or forest types, are often inconclusive since commonly used sample sizes do not provide precise estimates of the number of species present. While the ecological homogenization hypotheses can be tested under conditions of unequal sampling effort, we suggest robust methods such as PERMANOVA and the Raup-Crick dissimilarity index. A framework for selecting appropriate methods is also discussed. As forests are increasingly being altered by anthropogenic drivers, future studies using disparate data sources must account for differences in measurements and sampling protocols in order to produce results that are both statistically defensible and useful for science-based management.

Seed dispersal limitation causes negative legacy effect on restoration of grassland plant diversity on ski slopes

Past forest use often has a long‐term negative impact on the recovery of the original plant composition of semi‐natural grasslands, which is known as a legacy effect. This study investigates the impact of seed dispersal limitations on the restoration of grassland plant diversity on ski slopes with past forest use, highlighting the negative legacy effect on biodiversity recovery. Focusing on ski areas, our research contrasts the vegetation on ski slopes originally created on semi‐natural grasslands such as pasture (pasture slopes) and constructed by clearing secondary forests or conifer plantations (forest slopes). We examined species richness and diversity, considering seed dispersal modes, grassland management history, and seed source proximity. We reveal that the proximity to species‐rich grassland sources is pivotal for the restoration of native grassland vegetation. Particularly, wind‐dispersed species show significant recovery on slopes with sustained management for more than 70 years and those with neighboring species‐rich grasslands, suggesting that both the duration of management and the proximity to seed sources are critical for overcoming the legacy effects of past forest use. Meanwhile, gravity‐dispersed species failed to recover their richness and diversity regardless of both the duration of management and the proximity to seed source grasslands, which their diversity recovered where seed sources neighbored. Our findings emphasize the importance of considering seed dispersal limitation and management history in the restoration and conservation of grasslands and their biodiversity, particularly in landscapes experiencing past human intervention.

The Effect of Landscape History on the Urban Environment: Past Landscapes, Present Patterns

Urban environments around the world are the result of their evolutionary and geographic history, and more contemporary influences of the social, cultural, economic, political and technical systems that shaped their construction. In this chapter, we discuss urban filters as the overarching framework within which specific aspects pertaining to the history of the landscape will be discussed. Legacy effects are discussed under the subthemes of urban form and development history, biodiversity, biological invasions, soils, urban freshwater bodies, natural disasters, the effects of war on urban environments, and extinction debts. Lastly, the collective effects of changing urban environments over time manifests in citizens through desensitisation, termed generational amnesia or the extinction of experience, which has important consequences for residents' perceptions towards urban biodiversity. In trying to disseminate patterns and processes in urban areas of the Global South, this overview revealed that more urban ecology research is required to begin untangling the effects of urbanisation and bioclimatic regions from the drivers that are much more context specific. Growing the number of studies conducted in the Global South is critical to ensure that there is an evidence base that is representative of the full range of conditions for cities around the world.
