Invasive plant species in the forest parks of Yekaterinburg

Invasive species-introduced species, spontaneously settled outside their natural range, and successfully adapted to the new growing conditions. The problem of invasive species penetration, both herbaceous and woody, has long been a concern of scientists, their views on this issue being contradictory. In the forest parks of Yekaterinburg there is a significant number of introduced species-invasive species. The occurrence of invasive species was considered in three forest parks of the city. The article shows invasive species high occurrence, wide amplitude of ecological plasticity, lack of response to shade density conditions in forest parks and urban plantations. They easily adapt to the conditions of different shade density and increased recreational load, both in urban areas plantations and in the conditions of a forest park. The studied species can be recommended for use in urban parks and forest parks. Cotoneaster lucidus Schlecht. and Amelanchier spicata (Lam.) K. Koch. are quite decorative and can be used both in the formation of edges, landscape groups and as undergrowth species. © 2019 IOP Publishing Ltd. All rights reserved

New Host Records and Developmental Notes on the Pear Slug \u3ci\u3eCaliroa Cerasi\u3c/i\u3e (Hymenoptera: Tenthredinidae), Feeding on \u3ci\u3eCotoneaster\u3c/i\u3e and \u3ci\u3eChaenomeles\u3c/i\u3e Species.

The pear slug. Caliroa cerasi was collected and reared to adulthood on flowering quince and three species of Cotoneaster. This is the first record of C. cerasi attacking any member of the genus Chaenomeles and the first confirmation of feeding on Cotoneaster in North America. Adult emergence, oviposition, and larval development were evaluated under both laboratory and field conditions. Females lay an average of 48 eggs, with about two-thirds of the oviposition occurring during their first 24 hours. A method for monitoring adult emergence in the field was developed

Hawthorn Lace Bug (Hemiptera: Tingidae), First Record of Injury to Roses, with a Review of Host Plants

Hawthorn lace bug, Coryrhucha cydoniae (Fitch), is reported for the first time as damag- ing roses. Injury to climbing and hybrid Tea roses is described, and a list of known host plants is provided based on observations in Pennsylvania and review of literature. Preferred hosts are native and cultivated species of Amelanchier and Craraegus and ornamental Cotoneasrer and Pyracanrha. Damage to crabapple. fruit trees, mountain ash. and other rosaceous plants may occur when they are grown near more favored hosts

No hay diferencias en la diversidad genética entre arbustos de Cotoneaster franchetii (Rosaceae) de rangos nativos y no nativos

La diversidad genética de los arbustos de Cotoneaster franchetii es similar entre los rangos de distribución nativo y no nativo. Debido al efecto fundador comúnmente se asume que las plantas tienen mayor diversidad genética en su rango nativo que en las áreas donde fueron introducidos. Sin embargo, pocos estudios han probado este supuesto incluyendo la comparación entre los rangos nativos y no nativos. Nosotros analizamos marcadores de AFLP en 149 individuos de Cotoneaster franchetii pertenecientes a cinco poblaciones nativas (China) y cinco no nativas (Argentina) donde este arbusto invade exitosamente diferentes ambientes, y forma rodales extensos y monoespecíficos. Además comparamos los estimadores de diversidad genética y evaluamos la diferenciación genética entre las poblaciones examinando los valores de Fst y realizando un ACoP, un AMOVA y una prueba de Mantel. No se encontró evidencia de diversidad genética reducida en las poblaciones no nativas, mientras que el ACoP reveló dos grupos distintos, reflejando sus orígenes argentinos y chinos. Diez individuos de dos de las poblaciones chinas fueron la excepción, debido a que se agruparon dentro de las poblaciones argentinas, apoyando la idea de introducciones múltiples desde China hacia Argentina.It is commonly assumed that plants have more genetic diversity in their native range than in areas where they have been introduced due to founder effects. However, few studies have proven this assumption and included the comparison between non-native and native ranges. We analyzed AFLP fingerprint patterns of 149 individuals from five native (China) and five non-native (Argentina) populations of Cotoneaster franchetii, a shrub which successfully invades different habitats and forms extensive monospecific stands. We compared genetic diversity estimates and assessed genetic differentiation among populations by inspecting FST values and conducting a PCoA, an AMOVA and a Mantel test. No evidence was found for reduced genetic diversity in non-native populations while the PCoA revealed two distinct groups, reflecting their Chinese and Argentine origin. The exceptions were ten individuals from two Chinese populations that clustered within the Argentine populations, supporting the idea of multiple introductions from China to Argentina.Fil: Lett, Irene.

Naturalised species of the genus Cotoneaster in Halle (Saale) and its surrounding

Zu verwilderten Vorkommen von Taxa der Gattung Cotoneaster in Deutschland gibt es nur wenige Untersuchungen. Oft basieren diese aufgrund taxonomischer und nomenklatorischer Unsicherheiten und wegen Problemen bei der Einschätzung des floristischen Status bisher nur auf sporadischen Beobachtungen. In der Dölauer Heide, einem Stadtwald von Halle (Saale), wurden subspontane Vorkommen von Cotoneaster bullatus BOIS, C. cornifolius (REHDER et H. E. WILSON) FLINCK et B. HYLMÖ, C. dielsianus E. PRITZ. ex DIELS, C. divaricatus REHDER et H. E. WILSON, C. lucidus SCHLTDL., C. aff. multiflorus, C. villosulus (REHDER et H. E. WILSON) FLINCK et B. HYLMÖ und C. zabelii C. K. SCHNEID. festgestellt. In der weiteren Umgebung von Halle wurde auch subspontanes Auftreten von C. horizontalis DECNE. und C. nitens REHDER et H. E. WILSON ermittelt. Insbesondere C. villosulus und C. divaricatus werden als invasive Arten eingeschätzt. Cotoneaster cornifolius und C. lucidus sind fest eingebürgert und haben das Potenzial, invasiv werden zu können. Die synanthropen Vorkommen mehrerer Cotoneaster- Arten haben überwiegend auffallend höheren Wuchs sowie größere Blätter und Früchte als in den Originalbeschreibungen angegeben.Recent studies in an urban forest of the city Halle (Germany) attest the occurrence of wild growing Cotoneaster bullatus BOIS, C. cornifolius (REHDER et H. E. WILSON) FLINCK et B. HYLMÖ, C. dielsianus E. PRITZ. ex DIELS, C. divaricatus REHDER et H. E. WILSON, C. lucidus SCHLTDL., C. aff. multiflorus, C. villosulus (REHDER et H. E. WILSON) FLINCK et B. HYLMÖ and C. zabelii C. K. SCHNEID. Cotoneaster horizontalis DECNE. and C. nitens REHDER et H. E. WILSON are found near Halle. Particularly Cotoneaster villosulus and C. divaricatus are considered to be invasive. Cotoneaster cornifolius and C. lucidus are permanently naturalised and are able to become invasive. Invasive populations show increased plant size and leaf area relative to original description of the species

Cotoneaster: A safe and easy way to reduce neonatal jaundice

Introduction: Consumption of cotoneaster may reduce neonatal jaundice. Aim: Hence this study was undertaken to determine the effect of mothers’ cotoneaster consumption on treatment of their neonates’ jaundice. Materials and Methods: In this randomized clinical trial study, 120 neonates with jaundice referred to a hospital in southwest Iran were enrolled by nonprobability sampling and divided randomly into four groups. In the first group both mothers and neonates received cotoneaster; in the second group only mothers; in the third group only neonates; and in the fourth group the neonates received distilled water as placebo. Phototherapy was done under the same condition for all neonates. Results: The reduction of bilirubin was significantly higher in treatment groups compared to control group (p<0.05). Bilirubin in the group of neonates whose mothers consumed cotoneaster was less compared to control group at 24 and 36 hours (p<0.05) and the highest reduction in bilirubin was observed in the first group. The mean duration of hospitalization was longer for the control group (p<0.05). Conclusion: Consumption of cotoneaster by both mothers and neonates caused a decrease in neonatal jaundice more rapidly compared to other groups and decreased the duration of hospitalization. Cotoneaster consumption by mothers, neonates, or both may be useful in treatment of neonatal jaundice. © 2016, Journal of Clinical and Diagnostic Research. All rights reserved
