We studied the anatomy of a rare narrow endemic species belonging to the Slovenian fl ora – Hladnikia pastinacifolia Rchb. Hladnikia is a monotypic genus with distinct taxonomic position within the Apiaceae family. The anatomical characteristics revealed by light and fl uorescence microscopy provided new insights regarding the pollen, leaf and root characteristics of H. pastinacifolia, improvin...

In this paper we consider a diffeomorphism f of a compact manifold M which contracts an invariant foliation W with smooth leaves. If the differential of f on TW has narrow band spectrum, there exist coordinates Hx : Wx → TxW in which f |W has polynomial form. We present a modified approach that allows us to construct mapsHx that depend smoothly on x along the leaves of W . Moreover, we show tha...

The Cellulose Synthase-Like D (CslD) genes have important, although still poorly defined, roles in cell wall formation. Here, we show an unexpected involvement of CslD1 from maize (Zea mays) in cell division. Both division and expansion were altered in the narrow-organ and warty phenotypes of the csld1 mutants. Leaf width was reduced by 35%, due mainly to a 47% drop in the number of cell files ...

Received 10th December, 2012 Received in revised form 20, December, 2012 Accepted 5th January, 2013 Published online 31th January, 2013 Objective: To determine the mosquito larvicidal activity of leaf essential oil and their chemical constituents from Clausena anisata (Willd.) Hook. f. ex Benth. against Anopheles subpictus and Aedes albopictus. In addition, the chemical composition of the leaf ...

There is a need to develop indicators of mangrove condition using remotely sensed data. However, remote estimation of leaf and canopy biochemical properties and vegetation condition remains challenging. In this paper, we (i) tested the performance of selected hyperspectral and broad band indices to predict chlorophyll concentration (CC) on mangrove leaves and (ii) showed the potential of Landsa...

Peronospora belbahrii is a biotrophic oomycete attacking sweet basil. It propagates asexually by producing spores on dichotomously branched sporophores emerging from leaf stomata. Sporulation occurs when infected plants are incubated for at least 7.5h in the dark in moisture-saturated atmosphere at 10-27°C. Exposure to light suppresses spore formation but allows sporophores to emerge from stoma...

A linear relationship (r2=0.79, p<0.001) between the photochemical re ectance index (PRI) and photosynthetic light use eYciency (LUE) was found for eight plant species that exhibit a signiŽ cant range in foliage physical properties and nitrogen content. Experiments were conducted under artiŽ cial sunlight in a climate laboratory, using narrow-band (3.2 nm) canopy-level re ectance data to calc...

 The family Zoropsidae is currently represented by 15 genera and 87 species (World Spider Catalog 2015). Zoropsids are medium to large size spiders, with a narrow, bipartite cribellum and calamistrum; eight eyes in two rows, anterior eye row nearly straight, posterior row strongly recurved; median furrow longitudinal; toothed chelicerae; tibiae and metatarsi I, II equipped with several pairs of...

Lophiodes infrabrunneus Smith and Radcliffe, 1912 is redescribed on the basis of all known specimens. The species is redefined as: a species of Lophiodes with three dorsal spines, postcephalic spines absent; illicium relatively short, 13.3– 24.2% of SL; second and third dorsal spine relatively short, 12.2–21.2% and 9.1–20.6% of SL respectively, a narrow leaf–like flap, and tendrils present on s...

Raveniopsis microphyllus K.Wurdack, sp. nov., a new species known only from a single peak in the Pakaraima Mtns. of Guyana, is described and illustrated. This white-flowered shrub adds to the many narrow-endemic Guiana Shield species in the genus, and is unique in bearing small, trifoliate, sclerophyllous leaves. Leaf anatomy and surface micromorphology of the new species were examined to docum...
