This publication was originally developed to help answer requests from participants of the Florida Yards & Neighbor­hoods program in Miami-Dade County, now Friendly LandscapingTM (FFL), for a list landscape plants suitable south and has become critical reference county. The resulting includes over 330 species low-maintenance plants. For each species, we provided common scientific names, family, size, light preference, salt tolerance, establishment status, invasive status potential, other...

Abstract Recently developed phylogeographic analyses that incorporate genealogical relationships of alleles offer the exciting prospect disentangling historical from contemporary events. However, relative advantages and shortfalls this approach remain to be studied. We compared nested cladistic method more traditional analysis variance in a study intraspecific genetic variation freshwater mussel, Lampsilis hydiana. surveyed 257 specimens for nucleotide sequence level fragment mitochondrial...

Life history and population dynamic patterns of Gambusia affinis in southeastern Louisiana varied spatially temporally 1990 1991, but were consistent with previous reports this species the southern regions its natural range. Several differences exist among populations different geographic within United States, as reported literature, which do not follow a‘ native v . introduced’ dichotomy: (1) brood size decreases offspring increases from north to south; (2) large overwintered females...

Summary During the 1999–2000 and 2000–2001 seasons, 19 commercial squash fields in vicinity of Homestead, Florida (USA) were examined for diseases caused by Phytophthora capsici . In each six which two or more isolates P. recovered, both Al A2 mating types present, recovered from same plant five times. Insensitivity to mefenoxam was common among isolates, with EC50s ranging 5 μg ml −1 than 60 Of 15 weed species that as possible alternative hosts pathogen, only purslane, Portulaca oleracea ,...

Synopsis In rows 81/2 feet apart, highest ear corn yields occurred at closer within‐row spacings than those which usually give maximum between‐row spacings. Differences in from 1 to 4 inches had little effect on total plant weight per acre, but the within this range increased stover: ratio. Root pattern of individual plants changed circular oblong below 8 inches.

Abstract Evidence from a 39‐year record of corn yield trop rotation experiments on Wooster silt loam soil fails to show long‐term cumulative trend effects commonly‐used belt rotations productivity. Yield levels characteristic given were quickly reached with no pronounced trends thereafter. In general, level was associated nitrogen level. Long‐term downward in apparent productivity observed under conditions continuous cropping and severe erosion.

This paper describes the significance of arborescent cycad “tiusinte” to Honduran culture. Dioon mejiae is a wild food that supplements maize-bean diets for an estimated 33,000 indigenous and mestizo Hondurans. Female cones are harvested their seeds, which processed made into tamales, tortillas, other products. Leaves used variety Catholic celebrations; minor uses leaves female cone parts also persist. Tiusintes, common-property resource, being destroyed by adverse effects timber extraction,...

Ceratozamia aurantiaca, a new cycad species from Oaxaca, Mexico, is described. The endemic to lowland karst tropical rainforests of the northern mountains (Sierra Norte region). This related C. subroseophylla and robusta, together considered part robusta complex due their shared characteristics: robust, upright trunk; large long leaves with densely armed petioles linear subfalcate leaflets; megastrobili. as epithet suggests, easily distinguished other by orange color its emerging leaves,...

White alder (Alnus rhombifolia) is a fast-growing tree native to the western United States and planted frequently in landscapes. In September 2010, mature leaves of white with small, orange-yellow pustules were collected commercial nursery Santa Cruz County, CA. Approximately 25 trees affected. Collected sent California Department Food Agriculture Plant Pest Diagnostics Laboratory. Young uredinial bullate, urediniospores emerging from single pore pustule. Spiny cells lined ostiole. With age,...
