Abstract Ecological succession – how biological communities re‐assemble and change over time following natural or anthropogenic disturbance has been studied since the birth of ecology, resulting theoretical framework underpins many aspects discipline. Recently, mechanistic basis classic theory advanced by studies plant microbial interactions, functional traits, retrogressive stages ecosystem development. This special issue brings together a series papers that highlight these contemporary...
Abstract Studies of succession have a long history in ecology, but rigorous tests general, unifying principles are rare. One barrier to these theory is the paucity longitudinal studies that span broad gradients disturbance severity characterize large, infrequent disturbances. The cataclysmic eruption Mount St. Helens (Washington, USA) 1980 produced heterogeneous landscape conditions, including primary secondary successional habitats, affording unique opportunity explore how rates and...
Succession and community assembly research overlap in many respects, such as through their focus on how ecological processes like dispersal, environmental filters, biotic interactions influence structure. Indeed, recent advances have been made by successional studies that draw modern analytical techniques introduced contemporary studies. However, generally lack a temporal perspective, both the forces structuring communities might change over time historical contingency (e.g. priority effects...
1. Annual above-ground net primary productivity (ANPP) in mesic grasslands is known to be highly temporally variable. While yearly precipitation or average temperature can explain some of this temporal variability, much the variation ANPP remains unexplained. 2. Here we address heretofore unexplained 25 years data from a grassland at Konza Prairie (north-eastern Kansas) by examining effects and during periods relevant phenology growth cycle dominant C4 grasses flowering stalk production...
Essential workers in agriculture and food production have been severely affected by the ongoing COVID-19 pandemic.To identify risk factors associated with SARS-CoV-2 infection among farmworkers California.This cross-sectional study invited California's Salinas Valley (Monterey County) receiving transcription-mediated amplification (TMA) tests for at federally qualified community clinics sites to participate. Individuals were eligible if they not pregnant, 18 years or older, had conducted...
To investigate the exposure-response (E-R) relationship, including exposure-efficacy and exposure-safety, of ropeginterferon alfa-2b treatment in patients with polycythaemia vera (PV).
Genotypic diversity of dominant species has been shown to have important consequences for community and ecosystem processes at a fine spatial scale. We examined the fine-scale (i.e., plant neighborhood scale, <1 m2) genotypic structure Andropogon gerardii, in tallgrass prairie, which is productive endangered grassland ecosystem, employing commonly used amplified fragment length polymorphism (AFLP) technique. In this paper we two methods assess genetic perennial grass, (1) determined how many...
• To better understand invasion dynamics, it is essential to determine the influence of genetics and ecology in species persistence both native nonnative habitats. One approach assess patterns selection on floral growth traits individuals Mimulus guttatus (Phrymaceae) has a mixed mating system grows under variable water conditions across its range North America. Field investigations plant size were conducted two populations. Field-collected seed was grown crossed glasshouse using paternal...
Summary Global change is increasing the frequency and magnitude of resource fluctuations (pulses) at multiple time‐scales. According to fluctuating availability hypothesis ( FRAH ), susceptibility an ecosystem invasion (i.e. invasibility) expected increase whenever supply exceeds that which utilized by native communities. Thus, global has potential invasibility around world. Here, we test adding seeds a target invader grass species long‐term climate experiment manipulating precipitation...
Summary The well‐described pattern of a few common and many rare species in plant communities (dominance‐diversity curves) also has been documented within populations dominant species. Understanding how these genotypes coexist implications for genotype richness may impact community ecosystem processes. Some studies have shown that increased leads to an increase above‐ground productivity, suggesting niche complementarity between genotypes. However, mechanistic understanding complement one...
Abstract Background Provision of critical care in rural areas is challenging due to geographic distance, smaller facilities, generalist skill mix and population characteristics. Internationally, the amalgamation telemedicine retrieval medicine services are developing overcome these challenges.

We aim describe patient encounters with vCare from call initiation at referring site definitive...
The use of trait-based approaches to understand ecological communities has increased in the past two decades because their promise preserve more information about community structure than taxonomic methods and potential connect responses subsequent effects ecosystem functioning. Though are a powerful tool for describing communities, many important properties commonly-used trait metrics remain unexamined. Previous work with simulated distributions shows sensitivity functional diversity...
Background: The genetic diversity within populations has been shown to affect ecosystem functions, including productivity and invasion resistance. To date most experiments have focused on manipulation of genotypic richness ignored other measures diversity.Aims: In the present study we aimed establish whether manipulated genomic dissimilarity Andropogon gerardii resistance.Methods: We created experimental mesocosms with three levels richness: one-, three-, nine-genotypes. three-genotype...
Abstract Question Both genetic diversity within a dominant species and have been shown to affect productivity. However, these two levels of the potential productivity in similar or opposing ways. Our study assessed direct indirect relationships between grass plant community on mesic grassland with naturally co‐occurring genotypes species. Location Konza Prairie Biological Station, Kansas, USA (39°05′35″ N, 96°33′31″ W). Methods We conducted at sites (~65 plots per site) intact tallgrass...
Diversity-disturbance research has focused on community diversity, but disturbance frequency could impact diversity within species as well, with important consequences for and ecosystem function. We examined patterns of genetic a dominant grass species, Andropogon gerardii, in native North American tallgrass prairie sites located eastern Kansas that have been subjected to gradient fire treatments (burned every 1, 2, 4 or 20 years) since the 1970s. In addition, we were able assess...
Abstract Plant morphology is inherently mathematical in that describes plant form and architecture with geometrical topological descriptors. The geometries topologies of leaves, flowers, roots, shoots their spatial arrangements have fascinated biologists mathematicians alike. Beyond providing aesthetic inspiration, quantifying has become pressing an era climate change a growing human population. Modifying morphology, through molecular biology breeding, aided by perspective, critical to...
