Vascular plants of Mammoth Spring, Arkansas
Aquatic vegetation was surveyed at Mammoth Spring, AR, representing the first extensive survey of this resource since 1859. Thirty-eight angiosperm species were identified during this study, including 17 species of monocots and 21 species of eudicots. Seven species were nonnative, but they are not considered invasive. Eleven of the species reported from the spring in 1859 are still present, but some previously reported taxa were not found and other taxa are reported for the first time. Species no longer found at the spring may be due to misidentifications in the earlier study or extirpations due to climate change, anthropogenic disturbances, or unknown factors. The diversity of aquatic plants in Mammoth Spring is similar to that reported from other regional large springs and a few species are shared in common among these springs.

Introduced Japanese burrowing cricket (Orthoptera: Gryllidae: Velarifictorus (Velarifictorus) micado) range continues to expand in North America
Japanese burrowing cricket, Velarifictorus (Velarifictorus) micado (Saussure, 1877), was introduced into the eastern United States in 1959 and has since increased its distributional range to include the eastern Great Plains and the northern United States. Although generally thought of as an urban species associated with human habitation, some specimens are now being captured in more remote areas, which is attributed to this species sometimes being macropterous and dispersing through flight. Public data sources such as BugGuide and iNaturalist were found to be sound, passive tools for identifying the expanding range of this species in the Americas. Collection and observation in atypical habitats suggest that potential ecological impacts may be occurring.

Employee morale : driving performance in challenging times
\"Performance is the key outcome of high morale, and the reason why it should be taken so seriously: with research gathered from some of the world's largest employee opinion databases and best academic centres, the authors lay out the morale-performance connection. Now raised from just 'touchy-feely' to 'mission critical', employee morale is finally getting the attention which it deserves. As it does, organizations are changing everything from their structure to their processes to take account of this fact, and starting to manage themselves around the need to measure and improve morale on an ongoing basis. Starting with the hiring process, to every single promotion, and via ongoing methods which the authors examine in detail, morale is increasingly the focus, high morale the goal.

A genotyping array for the globally invasive vector mosquito, Aedes albopictus
Background
Although whole-genome sequencing (WGS) is the preferred genotyping method for most genomic analyses, limitations are often experienced when studying genomes characterized by a high percentage of repetitive elements, high linkage, and recombination deserts. The Asian tiger mosquito (
Aedes albopictus
), for example, has a genome comprising up to 72% repetitive elements, and therefore we set out to develop a single-nucleotide polymorphism (SNP) chip to be more cost-effective.
Aedes albopictus
is an invasive species originating from Southeast Asia that has recently spread around the world and is a vector for many human diseases. Developing an accessible genotyping platform is essential in advancing biological control methods and understanding the population dynamics of this pest species, with significant implications for public health.
Methods
We designed a SNP chip for
Ae. albopictus
(Aealbo chip) based on approximately 2.7 million SNPs identified using WGS data from 819 worldwide samples. We validated the chip using laboratory single-pair crosses, comparing technical replicates, and comparing genotypes of samples genotyped by WGS and the SNP chip. We then used the chip for a population genomic analysis of 237 samples from 28 sites in the native range to evaluate its usefulness in describing patterns of genomic variation and tracing the origins of invasions.
Results
Probes on the Aealbo chip targeted 175,396 SNPs in coding and non-coding regions across all three chromosomes, with a density of 102 SNPs per 1 Mb window, and at least one SNP in each of the 17,461 protein-coding genes. Overall, 70% of the probes captured the genetic variation. Segregation analysis found that 98% of the SNPs followed expectations of single-copy Mendelian genes. Comparisons with WGS indicated that sites with genotype disagreements were mostly heterozygotes at loci with WGS read depth < 20, while there was near complete agreement with WGS read depths > 20, indicating that the chip more accurately detects heterozygotes than low-coverage WGS. Sample sizes did not affect the accuracy of the SNP chip genotype calls. Ancestry analyses identified four to five genetic clusters in the native range with various levels of admixture.
Conclusions
The Aealbo chip is highly accurate, is concordant with genotypes from WGS with high sequence coverage, and may be more accurate than low-coverage WGS.
Graphical Abstract
Journal Article
The prince & the coyote
\"Fifteen-year old crown prince Acolmiztli wants nothing more than to see his city-state of Tetzcoco thrive. A singer, poet, and burgeoning philosophical mind, he has big plans about infrastructure projects and cultural initiatives that will bring honor to his family and help his people flourish. But the two sides of his family, the kingdoms of Mexico and Acolhuacan, have been at war his entire life - after his father risked the wrath of the Tepanec emperor to win his mother's love. When a power struggle leaves his father dead and his mother and siblings in exile, Acolmiztli must run for his life, seeking refuge in the wilderness. After a coyote helps him find his way in the wild, he takes on a new name - Nezahualcoyotl, or \"fasting coyote\" (\"Neza\" for short). Biding his time until he can form new alliances and reconnect with his family, Neza goes undercover, and falls in love with a commoner girl, Sekalli. Can Neza survive his plotting uncles' scheme to wipe out his line for good? Will the empire he dreams of in Tetzcoco ever come to life? And is he willing to risk the lives of those he loves in the process? This action-packed tale blends prose and poetry - including translations of surviving poems by Nezahualcoyotl himself, translated from classical Nahuatl by the author. And the book is packed with queer rep - queer love stories, and a thoughtful depiction of pre-Columbian understandings of gender that defy the contemporary Western gender binary.\"-- Provided by publisher.

Supporting process improvements with process mapping and system dynamics
Purpose
The purpose of this paper is to study the effectiveness of combining process mapping and system dynamics (SD) in an organization’s ongoing business process improvement projects.
Design/methodology/approach
Norfield Industries, designer and manufacturer of prehung door machinery, used process mapping and SD in a project targeting the improvement of its design document control process. The project team first used process mapping to document its current process and identify potential improvements. The team then developed an SD model to investigate the potential impacts of proposed process changes.
Findings
The case study supports the communication and transparency benefits of process mapping reported in earlier studies. Consistent with other case studies using simulation, SD provided useful insights into possible results of proposed process changes.
Research limitations/implications
The findings have limitations with respect to generalizability consistent with the use of a case study methodology.
Practical implications
Organizational managers desiring to include simulation modeling in process improvement efforts have a choice between discrete event simulation and SD. SD may prove able to consume less organizational resources than discrete-event simulation and provide similar benefits related to reducing the risks associated with process changes.
Originality/value
The current case study adds to the existing literature documenting the use of process mapping combined with simulation modeling in process improvement efforts. The case study supports existing literature regarding the value of process mapping in making system processes more transparent. The results also support previous findings regarding the value of SD for simulating the possible results associated with scenarios under consideration for process improvements.
