Long-Term Changes in the Bird Community of Palenque, Chiapas, in Response to Rainforest Loss
Biodivers Conserv (2010) 19:21–36 DOI 10.1007/s10531-009-9698-z ORIGINAL PAPER Long-term changes in the bird community of Palenque, Chiapas, in response to rainforest loss Michael A. Patten Æ He´ctor Go´mez de Silva Æ Brenda D. Smith-Patten Received: 18 March 2008 / Accepted: 22 July 2009 / Published online: 6 August 2009 Ó Springer Science+Business Media B.V. 2009 Abstract With increased human populations and subsequent pressure to develop or farm land, the rate of fragmentation of tropical rainforests has accelerated in the past several decades. How native organisms respond to such fragmentation has been the subject of intense study in temperate ecosystems and at several tropical sites in Central and South America, but there has been little study of this phenomenon in Mexico, the country bridging the Neotropics and temperate North America. A reason for this neglect is an apparent lack of long-term data; however, such data can be obtained from ‘‘non-tradi- tional’’ sources, such as birders and tour leaders. We make innovative use of such data, combining them with more traditional data (e.g., museum specimens) to create a record of occurrence for Palenque, Mexico, from 1900 to 2009, including a near-continuous pres- ence–absence record since 1970. We analyzed these data using logistic regression and, importantly, recent statistical advances expressly for sighting records. As recently as the 1960s Palenque’s forest was contiguous with that of Selva Lacandona to the east, but the protected area surrounding the famous ruins is now a forested island. As a result, various species formerly known from the site have disappeared, including species both large (Crax rubra, Penelope purpurascens, and Ara macao) and small (Notharchus hyperrhynchos, Malacoptila panamensis, Microrhopias quixensis, and Pachyramphus cinnamomeus). -
Philephedra Tuberculosa a Soft Scale
March 2018 Philephedra tuberculosa a soft scale BACKGROUND A new soft scale pest was identified from papaya on Oahu. An infestation of Philephedra tuberculosa Nakahara & Gill was discovered on two papaya trees at the University of Hawaii, College of Tropical Agriculture and Human Resources (UH‐CTAHR) Poamoho Experiment Station in Waialua, Oahu. Specimens were first submitted to UH‐CTAHR in January 2018 and subsequently forwarded to Hawaii Department of Agriculture (HDOA), where a final identification was provided by the United States Department of Agriculture, Agricultural Research Service, Systematic Entomology Laboratory (USDA‐SEL) in February 2018. This is a new state record for Hawaii. According to Poamoho farm staff, a similar scale infestation was detected on the papaya around June 2017, but appeared under control with chemical application. DESCRIPTION P. tuberculosa is an oval‐shaped soft scale insect which ranges in color from yellow to bright green (Fig. 3) when alive and turns dark brown when dead. Females can be found associated with long, white egg sacs (Fig. 2a), where they will be covered by thick cottony wax (Fig. 4). Immature males are yellowish brown and can be found surrounded by wax filaments resembling white fungus (Figs. 6b, 7). Figure 1. Papaya fruits covered with Philephedra tuberculosa. DAMAGE These scales can cover fruit, petioles, leaves, trunk, and stems of hosts. Soft scale insects produce honeydew, promoting the growth of sooty mold. In high infestations, feeding along with thick sooty mold, can lead to the weakening of the plant, apical point distortion (seedling stage), flower and leaf drop, and possibly dieback. a HOSTS P. -
Lesser Antilles in Search of Amazonas 28Th February to 7Th March 2023 (8 Days)
Lesser Antilles In Search of Amazonas 28th February to 7th March 2023 (8 days) St. Vincent Amazon by Keith Clarkson The adventurous tour sees us travel to three of the most spectacular islands in the Lesser Antillean chain in search of several endemics (including each island's critically endangered species of Amazona parrot), and a host of indigenous regional Caribbean species - ranging from wonderfully vibrant orioles and enigmatic thrashers to delicate warblers and dazzling hummingbirds. The timing of the tour ensures that dotted amongst the myriad local species will be a host of North American migrants overwintering on the islands.

The Geranium Family, Geraniaceae, and the Mallow Family, Malvaceae
THE GERANIUM FAMILY, GERANIACEAE, AND THE MALLOW FAMILY, MALVACEAE TWO SOMETIMES CONFUSED FAMILIES PROMINENT IN SOME MEDITERRANEAN CLIMATE AREAS The Geraniaceae is a family of herbaceous plants or small shrubs, sometimes with succulent stems • The family is noted for its often palmately veined and lobed leaves, although some also have pinnately divided leaves • The leaves all have pairs of stipules at their base • The flowers may be regular and symmetrical or somewhat irregular • The floral plan is 5 separate sepals and petals, 5 or 10 stamens, and a superior ovary • The most distinctive feature is the beak of fused styles on top of the ovary Here you see a typical geranium flower This nonnative weedy geranium shows the styles forming a beak The geranium family is also noted for its seed dispersal • The styles either actively eject the seeds from each compartment of the ovary or… • They twist and embed themselves in clothing and fur to hitch a ride • The Geraniaceae is prominent in the Mediterranean Basin and the Cape Province of South Africa • It is also found in California but few species here are drought tolerant • California does have several introduced weedy members Here you see a geranium flinging the seeds from sections of the ovary when the styles curl up Three genera typify the Geraniaceae: Erodium, Geranium, and Pelargonium • Erodiums (common name filaree or clocks) typically have pinnately veined, sometimes dissected leaves; many species are weeds in California • Geraniums (that is, the true geraniums) typically have palmately veined leaves and perfectly symmetrical flowers. Most are herbaceous annuals or perennials • Pelargoniums (the so-called garden geraniums or storksbills) have asymmetrical flowers and range from perennials to succulents to shrubs The weedy filaree, Erodium cicutarium, produces small pink-purple flowers in California’s spring grasslands Here are the beaked unripe fruits of filaree Many of the perennial erodiums from the Mediterranean make well-behaved ground covers for California gardens Here are the flowers of the charming E. -

This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited. Abstract Over the last few decades, health evidence has been building for hibiscus tea (Hibiscus sabdariffa L. Malvaceae). Previous reviews show promise in relation to reducing cardiovascular risk factors, hypertension and hyperlipidaemia, but broader health perspectives have not been widely considered. Therefore, a scoping review was undertaken to examine the overall health effects of hibiscus tea. A PubMed search was undertaken for meta- analysis (MA) and systematic review papers, human randomised controlled trials (RCT) and laboratory publications investigating inter-relationships between hibiscus tea and health. Twenty-two publications were identified (four systematic/MA papers, nine human RCT controlled trials and nine laboratory publications).Strongest evidence exists in relation to cardiovascular disease, suggesting that drinking 2-3 cups daily (each ≈ 240-250 mL) may improve blood pressure and potentially serve as a preventative or adjunctive therapy against such conditions. -

Rashid2 1Department of Pharmacy, State University of Bangladesh, Dhaka-1207, Bangladesh 2Department of Pharmaceutical Chemistry, Faculty of Pharmacy, University of Dhaka, Dhaka-1000, Bangladesh 3Department of Microbiology, University of Dhaka, Dhaka-1000, Bangladesh Received: April 16, 2014; Accepted: August 11, 2014; Published (web): October 13, 2014 ABSTRACT: The study was designed to evaluate the bioactivities of crude methanol extracts of leaves of Malvaviscus arboreus and Phyllanthus reticulatus along with their pet-ether, carbon tetrachloride, chloroform and aqueous soluble partitionates. The antioxidant potential was evaluated by DPPH and Folin-Ciocalteau reagents using butylated hydroxytolune (BHT) and ascorbic acid as standards. In the DPPH free radical scavenging assay, the crude methanol extract of M. arboreus revealed the highest free radical scavenging activity with IC50 values 6.47 ± 0.78 µg/ml. In brine shrimp lethality bioassay, the chloroform soluble materials of M. arboreus displayed the highest cytotoxic potential having LC50 values 2.73 ± 0.36 µg/ml, whereas the standard vincristine sulphate exhibited an LC50 value of 0.45 µg/ml. In the thrombolytic activity assay, the pet-ether soluble fractions of M. arboreus and P. reticulatus revealed 55.60 ± 0.48 % and 18.99 ± 0.84% clot lysis, respectively. In the membrane stabilizing activity assay, the chloroform soluble fraction of M. arboreus inhibited heat- and hypotonic solution- induced haemolysis of RBCs by 54.60 ± 0.81 % and 66.96 ± 0.84 % as compared to 57.06 % and 72.79 % inhibition by acetyl salicylic acid (0.10 mg/ml), respectively. -

ABSTRACT: Members of the genera Corchorus L. and Hibiscus L. are excellent sources of natural fibers and becoming much important in recent times due to an increasing concern to make the world greener. The aim of this study has been to describe the molecular phylogenetic relationships among the important members of these two genera as well as to know their relative dispersal throughout the world. Monophyly of Corchorus L. is evident from our study, whereas paraphyletic occurrences have been identified in case of Hibiscus L.
