Abstract Aim For epiphytic plants trees are habitat units, and tree size determines epiphyte species richness. While growing, generate vertical microhabitats that exploited by epiphytes. One would expect to find four different types of relationship between richness: positive linear (young trees), neutral (old negative decaying trees) asymptotic (trees mixed class in a mature forest). We tested these relationships plots colonizing sweetgum pastureland, isolated remnant pastureland oaks) oaks...

New state and host records are provided for 28 species of Buprestidae collected in Morelos, Mexico the following genera: Acmaeodera Eschscholtz 1829, Actenodes Dejean 1833, Agrilus Curtis 1825, Brachys Chrysobothris Leiopleura Deyrolle 1864, Lius Pachyschelus Solier Tetragonoschema Thomson 1857.

Abstract: It has been suggested that vascular epiphyte composition and abundance may be influenced by forest host composition. We studied the species distribution among of a tropical dry in Mexico. All stands supported woody plants (dbh > 3 cm) ten plots (0.1 ha each) were counted. measured dbh all hosts, noted their bark characteristics (texture peeling behaviour), thickness most abundant species. Epiphyte was biased toward high concentration epiphytes three lower on five This consistent...

A survey of the camerobiid mites living on epiphytic bromeliads and forest floor a Mexican tropical dry was carried out. We found three new species genus Neophyllobius, which are described in this paper; first two, namely N. cibyci sp. nov. tepoztlanensis nov., were both inhabiting (Tillandsia spp.) two tree (Quercus obtusata Sapium macrocarpum); third, tescalicola soil litter under Q. obtusata. These can be differentiated from other by combination morphological characters adult females,...

The diversity, abundance and frequency of vascular epiphytes on the lower trunk were compared between two host groups a Mexican cloud forest: angiosperm trees (n = 72) tree ferns 28). bark five most frequent root mantle analysed for their thickness, water content, retention capacity pH. A total 55 epiphyte species 910 individuals found 27 species. On hosts with dbh range 5–10 cm, significantly more diverse (4.3±0.9 per host) abundant (12.5±2.2 than (1.9±0.2 3.9±0.6 host). However, these...

Abstract: In central Veracruz, Mexico, coffee plantations have replaced large areas of lower montane cloud forest. Shade‐coffee with high levels structural diversity provide refuge for forest‐dependent biota (e.g., birds and insects). Orchids typical natural forest may also be found in the canopy shade‐coffee agroecosystems. It is not known, however, whether these are relicts from original vegetation or if themselves necessary conditions to support a self‐sustained orchid population. We...

Abstract: Seed dispersal into fragmented tropical landscapes limits the rate and character of ecological succession between forest remnants. In a novel experiment in recovery remnants, 120 1-m 2 seed traps were placed fenced plots active pasture 90–250 m from forest, nearby primary secondary forests. Total rain December 2006 to January 2008 included 69 135 seeds 57 woody species. High richness early-successional trees occurred all habitats, but late-successional plants was much lower...

Abstract: Tree species are potential hosts for epiphytes; however in some forests epiphytes have a biased distribution among hosts. In tropical dry forest of Mexico, previous research showed that there trees with few epiphytes. It is possible the bark these contain allelochemicals influence epiphyte seed germination. The aims this study were (1) to determine whether low abundance ( Ipomoea murucoides , I. pauciflora and Lysiloma acapulcense ) would inhibit germination Tillandsia recurvata...

Plant species abundance is partly determined by reproductive success and the factors that limit this success. We studied flowering phenology, breeding systems florivory in a community of seven epiphytic Tillandsia spp. tropical dry forest central Mexico. Flowering periods were distributed throughout year, corolla sizes suggested most share pollinators. The common system was self-incompatibility (Tillandsia achyrostachys, T. caput-medusae hubertiana), lydiae infertile, circinnatioides...

In several montane forests around the world, epiphytes coexist in mats, sharing rhizosphere and forming histosol-type soils rich nutrients. The role of these formation canopy soil fitness costs that face when cohabiting mats are unknown. a lower cloud forest central Veracruz, Mexico, 2-year factorial experiment was carried out with presence/absence ramets Phlebodium areolatum (Polypodiaceae), Tillandsia kirchhoffiana, T. multicaulis punctulata (Bromeliaceae). We examined (i) which epiphyte...

Abstract It is assumed that commensalistic and amensalistic relationships describe the interactions between epiphytes their phorophytes. However, several correlational studies suggest these can be antagonistic (structural parasitism) or mutualistic. The few field experiments showed contradictory outcomes did not control for branch age (being older branches with epiphytes). To test effect of epiphytic bromeliad Tillandsia recurvata on growth phorophytes, we performed a 1‐year greenhouse...

Background and aims -In low-precipitation environments, vascular epiphytes are expected to present low abundance species richness, could be restricted inhabit a small number of phorophyte species.At the northern limit tropical region, in southern Chihuahuan Desert, we determined epiphyte richness biomass, tested whether Tillandsia recurvata exhibits preference vertical was exhibited within Prosopis laevigata.Material methods thirteen study sites covering San Luis Potosi high plateau, area...

The high diversity of vascular epiphytes in neotropical montane forest has been explained as the result vertical stratification and specific relationships between their hosts trees at local scales. In a lower cloud forest, we studied host preferences 0.0625 ha plot where 41 > or = 10 cm DBH were sampled during 12 months 2001 2002. We found 43 epiphyte species growing on 15 tree genera. tested for strata using 19 taxa. strong evidence that divided canopy, but those dispersed by animals...

Seed dispersal permits the colonization of favorable habitats and generation new populations, facilitating escape from that are in decline. There is little experimental evidence factors limit epiphyte dispersion towards their hosts. In a tropical dry forest central Mexico, we monitored phenology species genus Tillandsia; tested experimentally whether precipitation could cause failures seed capture differs among vertical strata between host with high (Bursera copallifera) low (Conzattia...

Canopy soil (CS) volume reflect epiphyte community maturity, but little is known about the factors that retain CS or species succession within it. Humus fern (e.g. Phlebodium areolatum) appear capable of retaining CS. In ten Quercus spp. we sampled 987 mats to examine role common and crown traits determining volume, in order infer successional stages identify pioneer late species. Branch (height, diameter slope), cover were determined for each mat. Nutrient content was random samples 12...

Abstract The studies about the negative effect of epiphytes on their phorophytes show contradictory results and are based limited variables (e.g., shoot survival). On branches Bursera copallifera, we experimented with transplantation/removal Tillandsia recurvata artificial tussocks, measuring survival, growth, generation new shoots, production inflorescences fruits. Most single traits did not differ between treatments. shoots was lower in treatments where T. present increased it removed....
