A Bryophyte genus Lazarenkoa Ignatov & Ignatova (2019:227), family Leskeaceae Schimp.(1856:109) was described by Ignatov et al. (2019) on the basis of recent morphological and molecular results obtained by the plant species collected from region Primorsky Territory of Russia. Currently, genus Lazarenkoa Ignatov & Ignatova is monotypic having single species Lazarenkoa microphylla Ignatov & Ignatova (2019:227) and endemic to Russia. Unfortunately, this newly described Bryophyte genus Lazarenkoa Ignatov & Ignatova is a later homonym of Ukrainian Ascomycetes fungi genus Lazarenkoa Zerova (1938:170). Genus Lazarenkoa Zerova, is a monotypic with single species Lazarenkoa selaginellae Zerova (1938:170) belonging to the class Dothideomycetes Erikss. & Winka. (1997:5) described from shoot apices of Selaginella sibirica [Milde(1867:262)] Hieron(1900:290).

Essential Point

Phyllotaxis studies published in German in the 1930s have reported intriguing regularity in the arrangement of incipient leaves on shoot apices of a wide variety of plant species. However, these studies have received little attention today, even though they provide a crucial evidence base for understanding this mathematical phenomena. Here I recapitulate the essential point by means of illustrative examples. It is emphasized that accurate control of apical divergence angle is at the heart of the numerical riddle of spiral phyllotaxis. The accurate patterning at the shoot apex has an unexpected evolutionary benefit of being optimally adaptive in the subsequent events of phyllotactic change to occur on an elongating shoot.

P Flux

Effective landscape management practices in urban landscapes must include an awareness of nutrient removal from soil caused by leaching, and these practices should be those least damaging to freshwaters. Annual mean dissolved organic carbon (DOC), dissolved organic nitrogen (DON), nitrate-N, ammonium-N, soluble phosphate, and bicarbonate concentrations and fluxes were quantified in leachate from landscapes planted with different urban horticultural types. Plot vegetation consisted of either a single species or mixed species. The experiment was conducted at two sites in Texas with significantly different irrigation water chemistry. At the two sites, plant species had a significant effect on PO43--P flux, and irrigation chemistry had a significant effect on all nutrient fluxes. There was an interaction between plant species and irrigation chemistry for PO43--P flux (P < 0.05) only. The relationship between bicarbonate and DOC flux at sites was stronger and significant (0.92; P < 0.05) at the site irrigated with Na-HCO3 municipal tap water than at the site irrigated with Ca-HCO3 municipal tap water (R2 = 0.76, P = 0.05). Type of irrigation water chemistry may result in lower plant water uptake resulting in increased nutrients lost to leachate.

The Impact

Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the cover, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2011, 2015, and 2019, Heartland Network staff and contractors identified a cumulative total of 45 potentially problematic plant taxa in Lincoln Boyhood National Memorial. Of the 34 species found in 2019, we characterized 4 as very low frequency, 14 as low frequency, 9 as medium frequency, and 7 as high frequency. A single species exceeded a 10-acre threshold based on a mid-point estimate. Because of the number of problematic plant taxa, as well as the extent and cover of problematic plants in the park and the small park size, control efforts should focus on treating high priority species across the entire park. High priority species may include plant species capable of rapid spread, species at low population levels, and species which can effectively be controlled.

Abstract In a preliminary study, consumer perceptions of native plants in traditional and naturalistic settings was investigated. In Montana, 361 participants in an internet study reported their familiarity with both woody and herbaceous native plant species. Additional data were collected to determine their perceptions of native plants used in naturalistic designs through a conjoint study. Nearly half of the study participants recognized or had purchased most of the native plants shown in photographs. Results of the conjoint study showed that participants placed the greatest relative importance (62%) on landscape style as the most important factor in landscape design. They also preferred a naturalistic style over a more traditional style and mixed plant species to single species. Across all comparisons, the high relative importance of landscape style remained constant and was consistent with prior studies. Plant material (21.9%) and species diversity (16.2%) were half the relative importance of design style and remained relatively consistent through most comparisons. Even among those participants not familiar with native plants and those who had not purchased native plants, native plants were preferred in the landscapes. The demand for native plants may be reaching a critical stage for both commercial growers and the landscape profession. Although this study was limited to one state, results show that consumer interest is present and further investigation is warranted.

AbstractThe species of the aromatic plant family Apiaceae are mainly used as spices and foods, but the family also includes medicinal and some poisonous plant species. Due to the similar chemical compounds or aroma and morphology, the poisonous species are often mistaken for the edible aromatic species. It is therefore imperative to correctly identify the species present at the initial raw stage samples to ensure product safety and efficacy. At the molecular level, plant species can be identified using DNA loci either from nuclear or plastid genome with easily available universal oligonucleotides, a technique called DNA barcoding. However, this is possible when single-species plant material is present but may not work on a mixture of plants species. Another disadvantage is that using universal oligonucleotides is of limited help, especially if the adulterating material is present in low quantities. On the other hand, if using the species-specific oligonucleotides, only single specific adulterating plant material could be detected and, consequently, the unexpected adulterants may go undetected. Therefore, in the current work, four degenerated oligonucleotides from ITS1 and ITS2 regions of the nuclear genome were designed that can bind to a variety of Apiaceae genera only and not to other genera belonging to different plant families. These family-specific oligonucleotides were able to amplify a diagnostic PCR product from 16 Apiaceae species that, upon sequencing, revealed the identity of the plant it was derived from. The size of these products is around 140 bp for ITS1 and approximately 80 bp for the ITS2 region. The size range of the amplified products falls in the category of a desired mini-barcode size to be used for damaged/fragmented DNA and next generation sequencing.

In response to a clear gap in knowledge on the biodiversity of sessile Gnesiotrocha rotifers at both global as well as regional Southeast Asian scales, we performed a study of free-living colonial and epiphytic rotifers attached to fifteen aquatic plant species in Thale Noi Lake, the first Ramsar site in Thailand. We identified 44 different taxa of sessile rotifers, including thirty-nine fixosessile species and three planktonic colonial species. This corresponds with about 40 % of the global sessile rotifer diversity, and is the highest alpha-diversity of the group ever recorded from a single lake. The record further includes a new genus, Lacinularoides n. gen., containing a single species L. coloniensis (Colledge, 1918) n. comb., which is redescribed, and several possibly new species, one of which, Ptygura thalenoiensis n. spec. is formally described here. Ptygura noodti (Koste, 1972) n. comb. is relocated from Floscularia, based on observations of living specimens of this species, formerly known only from preserved, contracted specimens from the Amazon region. In addition, ten of the species recorded are added to the fauna of the Oriental region, twenty-seven are new to Thailand.

Nesting of Brachyodynerus magnificus magnificus was studied in the Crimea on saline land. The nests were horizontal or inclined burrows excavated by females in lateral walls of soil cracks developed on clay ground substrate. Structure of three nests was examined; they were located in cracks 6–7 cm in depth and 0.5–1.5 cm in width; nest entrances were opened at depths of 2.5–4 cm; they were simple round openings without entrance turrets or any other structures. Two nests were abandoned by females and both had burrows 19 mm long; the third one was complete and had a burrow 33 mm long divided by transverse mud partitions onto three cells 8–10 mm long and a vestibular cell 2 mm long stopped by a final mud plug. The cells were not different from other parts of the nest burrow. Females used a liquid sucked out from succulent leaves of two halophitic plant species of the family Chenopodiaceae during nest building and did not visit any open water sources. Females hunted for caterpillars of a single species of coleophorid moth, Aporiptura ochroflava; 22–27 caterpillars were stored in each cell. Adult feeding was recorded on flowers of eight plant species, but the main nectar source was flowers of Limonium scoparium. Males spent their time feeding on flowers and searching for females at nesting and hunting sites. The species probably has two generations per year and we observed the nesting of the second generation. The distribution of the species is summarized; its presence in East Europe is confirmed. The lectotype of Odynerus magnificus Morawitz, 1867 is designated.

Abstract Background: Documenting local ecological knowledge (LEK) has recently became a topic of considerable interest. LEK can contribute to various areas of ecology, including habitat management and conservation biology. It has been recently revealed that recreational fishers’ ecological knowledge (FEK) can also provide valuable information about different organisms and habitats, while recreational fishers’ ecological knowledge is understudied in many aspects and regions of the world. Methods: We aimed to record Hungarian recreational FEK on plant species related to freshwater habitats. Our research was conducted in three regularly fished water bodies in Hungary, namely Lake Velence, Keleti Main Canal, and Lake Látóképi, where a total of 72 interviews were conducted with recreational anglers. During interviews, 24 plant species occurring at freshwater habitats with common or sporadic distribution were shown to anglers as single species or in congeneric pairs. Miscellaneous plant related knowledge of anglers was also collected. Results: Anglers identified a total of 16 plant species. They used 45 botanical or folk names. An angler knew the name of 4.6 plants on average, and recognized 7.4 other species without naming it. According to our detailed analysis, anglers were able to name or at least recognise those plant species which are somehow related to fishing activities, are salient and/or common. Moreover, anglers at Lake Velence recognized less plant species, however, they also had less years of fishing experience compared to anglers of the other two locations. Conclusion: We found that recreational FEK exist even in the case of freshwater plants which are not the main focus of anglers. It is highly presumable that recreational fishers would be able to provide reliable ecologically related data for scientific research establishing future citizen science projects of nature conservation.

I sought to evolve plant species richness patterns on 22 Galápagos Islands, Ecuador, as an exploration of the utility of evolutionary computation and an agent-based approach in biogeography research. The simulation was spatially explicit, where agents were plant monocultures defined by three niche dimensions, lava (yes or no), elevation, and slope. Niches were represented as standard normal curves subjected to selection pressure, where neighboring plants bred if their niches overlapped sufficiently, and were considered the same species, otherwise they were different species. Plants that bred produced seeds with mutated niches. Seeds dispersed locally and longer distances, and established if the habitat was appropriate given the seed's niche. From a single species colonizing a random location, hundreds of species evolved to fill the islands. Evolved plant species richness agreed very well with observed plant species richness. I review potential uses of an agent-based representation of evolving niches in biogeography research.
