  • ALLELOPATHIC EFFECT of INVASIVE SPECIES GIANT GOLDENROD (SOLIDAGO GIGANTEA AIT.) on CROPS and WEEDS* Renata Baličević, Marija
    Herbologia, Vol. 15, No. 1, 2015 DOI 10.5644/Herb.15.1.03 ALLELOPATHIC EFFECT OF INVASIVE SPECIES GIANT GOLDENROD (SOLIDAGO GIGANTEA AIT.) ON CROPS AND WEEDS* Renata Baličević, Marija Ravlić, Tea Živković* Faculty of Agriculture, Josip Juraj Strossmayer University of Osijek, Kralja Petra Svačića 1d, 31000 Osijek, Croatia, corresponding author: [email protected] *Student, Graduate study Abstract The aim of the study was to determine allelopathic potential of inva- sive species giant goldenrod (Solidago gigantea Ait.) on germination and initial growth crops (carrot, barley, coriander) and weed species velvetleaf (Abutilon theophrasti Med.) and redroot pigweed (Amaranthus retroflexus L.). Experiments were conducted under laboratory conditions to determine effect of water extracts in petri dish bioassay and in pots with soil. Water extracts from dry aboveground biomass of S. gigantea in concentrations of 1, 5 and 10% were investigated. In petri dish bioassay, all extract con- centrations showed allelopathic effect on germination and seedling growth of crops with reduction over 25 and 60%, respectively. Both weed species germination and growth were greatly suppressed with extract application. In pot experiment, allelopathic effect was less pronounced. Reduction in emergence percent, shoot length and fresh weight of carrot were observed. Barley root length and fresh weight were reduced with the highest extract concentration. No significant effect on seedling emergence and growth of A. theophrasti was recorded, while emergence of A. retroflexuswas inhib- ited for 14.4%. Germination and growth of test species decreased propor- tionately as concentration of weed biomass in water extracts increased. Differences in sensitivity among species were recorded, with A. retroflexus being the most susceptible to extracts.

We explore the influence of each gene region on the support given to each node of the most parsimonious tree derived from a combined analysis of all three genes using Partitioned Bremer Support. We also explore the influence of assuming equal weights for all characters in the combined analysis by investigating the stability of clades to different transition/transversion weighting schemes. We find many strongly supported and stable clades in the Nymphalinae. We are also able to identify ‘rogue’

  • Descriptions of Two New Chlosyne (Nymphalid~) from Mexico, with a Discussion of Related Forms
    148 Vo1.14: no.Z DESCRIPTIONS OF TWO NEW CHLOSYNE (NYMPHALID~) FROM MEXICO, WITH A DISCUSSION OF RELATED FORMS by DAVID L. BAUER Some years ago while examining the series of C hlosyne lacinia Geyer in the collection of F. M. BROWN, I noticed five specimens without marginal or submarginal spots on the wings. These specimens were all from northeastern Mexico and this along with their other peculiarities interested me, so I set them aside and continued to examine the series. Later among the specimens of C hlosyne lacinia quehtala Reakirt, I found five more specimens which also did not have a trace of the marginal or submarginal spots on their wings. These last specimens were from southwestern Mexico. As soon as possible I examined the genitalia of these two insects to see if they were just another variation of the protean C. lacinia, of which I had already checked many forms, or something new. I was both surprised and delighted to find the genitalia w ere definitely not like those of true lacinia. Comparison with the genitalia of other species of Chlosyne showed them to be most like those of C. janais Drury. The next summer, 1954, a trip was taken to Mexico and several colonies of the first insect were found, its habits were observed, and a good series was collected, but only one specimen of the second insect was c3.ptured. However, that same year, and also two years later, KENT H. WILSON was collecting Papilio in Mexico, and knowing of my interest in the Chlosyne he collected as many as he could and sent them to me for study.

  • Arthropods of Elm Fork Preserve
    Arthropods of Elm Fork Preserve Arthropods are characterized by having jointed limbs and exoskeletons. They include a diverse assortment of creatures: Insects, spiders, crustaceans (crayfish, crabs, pill bugs), centipedes and millipedes among others. Column Headings Scientific Name: The phenomenal diversity of arthropods, creates numerous difficulties in the determination of species. Positive identification is often achieved only by specialists using obscure monographs to ‘key out’ a species by examining microscopic differences in anatomy. For our purposes in this survey of the fauna, classification at a lower level of resolution still yields valuable information. For instance, knowing that ant lions belong to the Family, Myrmeleontidae, allows us to quickly look them up on the Internet and be confident we are not being fooled by a common name that may also apply to some other, unrelated something. With the Family name firmly in hand, we may explore the natural history of ant lions without needing to know exactly which species we are viewing. In some instances identification is only readily available at an even higher ranking such as Class. Millipedes are in the Class Diplopoda. There are many Orders (O) of millipedes and they are not easily differentiated so this entry is best left at the rank of Class. A great deal of taxonomic reorganization has been occurring lately with advances in DNA analysis pointing out underlying connections and differences that were previously unrealized. For this reason, all other rankings aside from Family, Genus and Species have been omitted from the interior of the tables since many of these ranks are in a state of flux.

  • Allelopathic Effect of Invasive Species Giant Goldenrod (Solidago Gigantea Ait.) on Wheat and Scentless Mayweed
    8th international scientific/professional conference SECTION II Izvorni znanstveni rad / original scientific paper Allelopathic effect of invasive species giant goldenrod (Solidago gigantea Ait.) on wheat and scentless mayweed Marija Ravlić1, Renata Baličević1, Ana Peharda2 1Faculty of Agriculture, Josip Juraj Strossmayer University of Osijek, Kralja Petra Svačića 1d, Osijek, Croatia, e-mail: [email protected] 2Student, Faculty of Agriculture, Osijek, Croatia Abstract The aim of the research was to determine allelopathic potential of invasive species giant gol- denrod (Solidago giganetea Ait.) on germination and initial growth of wheat and weed species scentless mayweed (Tripleurospermum inodorum (L.) C.H. Schultz). Experiments were conducted under laboratory conditions to determine effect of water extracts in petri dish bioassay and in pots with soil. Water extracts from dry aboveground biomass of S. gigantea in concentrations of 1, 5 and 10 % (10, 50 and 100 g/l) were investigated. In petri dish bioassay, germination of wheat was slightly reduced, while all extract concentration inhibited wheat growth. T. inodorum germination and seedling growth was affected with higher extract concentration. Application of extract to pots had no effect on wheat emergence and growth, with the exception of 10 % extract which reduced root length. Emergence of T. inodorum was significantly decreased with 5 and 10 % extract for 38.5 and 49.0 %, respectively. Key words: allelopathy, Solidago gigantea Ait., crops, scentless mayweed, water extracts Introduction Excessive use of herbicides in most weed management systems is a major concern since it causes serious threats to the environment, public health and increases costs of crop production. The degree of weed seed germination inhibition and growth suppression which can be attributed to crop allelopathy is highly important and can be considered as a possible alternative weed management strategy (Asghari and Tewari, 2007., Macias, 1995.).

Triplinerviae in western North America: The Solidago lepida complex (Asteraceae: Astereae). Phytoneuron 2017-47: 1–43. Published 18 July 2017. ISSN 2153 733X A MULTIVARIATE STUDY OF SOLIDAGO SUBSECT. TRIPLINERVIVAE IN WESTERN NORTH AMERICA: THE SOLIDAGO LEPIDA COMPLEX (ASTERACEAE: ASTEREAE) JOHN C. SEMPLE , HARIS FAHEEMUDDIN , MARIAN K. SOROUR , AND Y. ALEX CHONG Department of Biology University of Waterloo Waterloo, Ontario Canada N2L 3G1 [email protected] ABSTRACT Solidago subsect. Triplinerviae includes four species native to western North America: S. altissima, S. elongata , S. gigantea, and S. lepida . All of these except S. gigantea have been included at one time or another within S. canadensis . While rather similar among themselves, each species is distinguished by different sets of indument, leaf, and inflorescence traits. A series of multivariate morphometric analyses were performed on 244 specimens to discover additional technical traits useful in separating the species and to elucidate problems with identification in a group of species complicated by multiple ploidy levels and considerable infraspecific variation. Statistical support for recognizing S. gigantea var. shinnersii and S. lepida var. salebrosa was generated in comparisons of the varieties with the typical variety in each species. Solidago subsect. Triplinerviae (Torrey & A. Gray) Nesom (Asteraceae: Astereae) includes 17 species native North and South America (Semple 2017 frequently updated). Semple and Cook (2006) recognized 11 species with infraspecific taxa in several species occurring in Canada and the USA: S. altiplanities Taylor & Taylor, S. altissima L., S. canadensis L., S. elongata Nutt., S.
