Design/methodology/approach: In airtight biodigesters with 200 mL of culture medium, 20 g of the following treatments were incubated by triplicate: T1: 100% Hr, T2: 80% Hr 20% Ll, T3: 60% Hr 40% Ll, T4: 40% Hr 60% Ll; these were inoculated with 20 mL of fresh rumen fluid and incubated at 380.5 °C for 24, 48, 72 and 96 h. The total gas and CH4 production were assessed; the data were analyzed in a completely randomized design. Results: The addition of 20%, 40% and 60% Ll in mixture with Hr decreased the neutral detergent fiber (NDF), acid detergent fiber (ADF), total gas and CH4 production, while the crude protein content increased. Study limitations/implications: In vivo studies are required / by including amounts higher than 20% Ll may improve energy utilization efficiency.

  • Fungal Pathogens of Hyparrhenia Rufa (Nees)
    Fungal pathogens of Hyparrhenia rufa (Nees) Stapf., an invasive weed in Puerto Rico, and their potential as biological control agents12 Verónica Rivera-Andújar3, Lydia I. Rivera-Vargas4 and Abner Rodríguez-Carias5 J. Agrie. Univ. P.R. 100(2):237-247 (2016) ABSTRACT Hyparrhenia rufa (Nees) Stapf., commonly known as jaragüa, faragüa or yaragüa grass, is an aggressive weed that has invaded cropland in Puerto Rico. To reduce the application of herbicides, the use of phytopathogenic fungi has been proposed for its control. Four fungal isolates associated with foliage lesions of H. rufa were identified as Curvularia sp., Fusarium sp., Phoma sorghina and Sphaeropsis sp. Their pathogenicity was tested under laboratory, greenhouse and field conditions. All fungal species were pathogenic in wounded tissues under laboratory conditions, whereas P. sorghina and Sphaeropsis sp. were the most virulent species under greenhouse conditions. Fusarium sp. was the most virulent in a field assay. All fungal isolates showed low levels of infection (level 1) in the field. Disease severity was estimated at 25% of the experimental plot area. To comply with Koch's postulates, all inoculated fungi were re-isolated on potato dextrose agar after pathogenicity tests conducted under laboratory, greenhouse and field conditions. This is the first report of Curvularia sp., Fusarium sp., P. sorghina and Sphaeropsis sp. as foliar pathogens of H. rufa. Key words: invasive weed, Hyparrhenia rufa, jaragüa grass, Curvularia sp., Fusarium sp., Phoma sorghina, Sphaeropsis sp., biocontrol RESUMEN Hongos patógenos de Hyparrhenia rufa, una maleza invasiva en Puerto Rico, y su potencial como agentes de control biológico Hyparrhenia rufa (Nees) Stapf., conocida comúnmente como pasto jaragüa, faragüa o yaragüa, es una maleza agresiva que ha invadido terrenos cultivables en Puerto Rico.

  • Species Convergence Into Life-Forms in a Hyperseasonal Cerrado in Central Brazil Silva, IA.* and Batalha, MA
    Species convergence into life-forms in a hyperseasonal cerrado in central Brazil Silva, IA.* and Batalha, MA. Laboratório de Ecologia Vegetal, Departamento de Botânica, Universidade Federal de São Carlos – UFSCar, CP 676, CEP 13565-905, São Carlos, SP, Brazil *e-mail: [email protected] Received September 21, 2006 – Accepted November 30, 2006 – Distributed May 31, 2008 (With 3 figures) Abstract Whether the functional structure of ecological communities is deterministic or historically contingent is still quite con- troversial. However, recent experimental tests did not find effects of species composition variation on trait convergence and therefore the environmental constraints should play the major role on community convergence into functional groups. Seasonal cerrados are characterized by a sharp seasonality, in which the water shortage defines the community functioning. Hyperseasonal cerrados experience additionally waterlogging in the rainy season. Here, we asked whether waterlogging modifies species convergences into life-forms in a hyperseasonal cerrado. We studied a hyperseasonal cerrado, comparing it with a nearby seasonal cerrado, never waterlogged, in Emas National Park, central Brazil. In each area, we sampled all vascular plants by placing 40 plots of 1 m2 plots in four surveys. We analyzed the species convergences into life-forms in both cerrados using the Raunkiaer’s life-form spectrum and the index of divergence from species to life-form diversity (IDD). The overall life-form spectra and IDDs were not different, indicating that waterlogging did not affect the composition of functional groups in the hyperseasonal cerrado. However, there was a seasonal variation in IDD values only in the hyperseasonal cerrado. As long as we did not find a seasonal variation in life-form diversity, the seasonal variation of convergence into life-forms in the hyperseasonal cerrado was a conse- quence of the seasonal variation of species diversity.

ABSTRACT Feed value is the potential of the feed to supply the nutrients required by an animal both quantitatively and qualitatively in order to support a desired type of production. Where chemical composition and digestibility of a given feed is known it is possible to calculate its energy content by using appropriate regression equations. Eleven tropical grass species and mixed grass hay, seven legumes and browse trees, and six concentrates were evaluated in terms of chemical composition (CP, EE, OM, CHO and NDF), digestibility (in vitro organic matter digestibility -IVOMD and enzyme solubility of organic matter- EZOM) and calculated energy values. The grass species were: Andropogon timorensis (Kunth), Rev. Gram., Brachiaria brizantha, (A.Rich) Stapf, Bothriochloa radicans (Lehm) A. camus, Chloris guyana Kunth, Cynodon dactylon (L.) Pers, Hyparrhenia rufa (Nees) Stapf, Panicum maximum (Jacq.), Pannisetum purpureum (Schumacher), Setaria sphacelata Stapf & C.

H. rufa es una hierba perenne de altura ampliamente naturalizada en regiones tropicales y subtropicales del mundo donde se ha introducido intencionadamente principalmente para mejorar la producción ganadera. Se utiliza para el pastoreo y para heno y ensilado. La especie se ha escapado de cultivo y se ha convertido en invasora en los Estados Unidos, Australia, México, Brasil, América Central y las Indias Occidentales. Es una hierba agresiva altamente tolerante a la sequía, el pastoreo y el fuego, que crece formando gradas altas y densas que desplazan a la vegetación nativa (CABI, 2016).

Therefore, it is important database. We review the competitive traits of TSGs and to be able to predict their likelihood of naturalisation and collate risk assessments conducted on TSGs. Of the c. impact. We explore whether plant height is of particular 11,000 grass species globally, 929 qualify (c. 8.6%) as importance in determining naturalisation success and TSGs. 80.6% of TSGs are woody bamboos, with the impact in Poaceae by comparing naturalisation of tall- remaining species scattered among 21 tribes in seven subfamilies. When all grass species were analysed, TSGs and non-TSGs did not differ significantly in the Electronic supplementary material The online version of probability of naturalisation.
