“…In the tropics, wind-dispersed plants are less numerous and diverse compared to temperate zones (Sakai 2001). Anemophilous pollination in angiosperms is a derived characteristic that has arisen, in an independent manner, 65 times during the evolutionary history of these plants and is present in 10% of the species in this plant group (Ackerman 2000).…”

-(Atmospheric pollen and spore content in the urban area of the city of Medellin, Colombia). The atmosphere of the urban area of the city of Medellin, Colombia was monitored with the objective of identifying airborne pollen and spores throughout a whole year. Sampling was performed between February 2010 and March 2011, coinciding with the La Niña climate phenomenon, which is characterized by a considerable increase in precipitation. Samples of airborne spores and pollen were obtained from a suction Hirst-type volumetric sampler. A total of 62 pollen and spores types were recorded during sampling, of which 30 were angiosperms, two were gymnosperms, 10 were monilophytes, and 20 were fungi. The families displaying the highest pollen counts were Oleaceae, Poaceae, Cyperaceae, Chenopodiaceae and Polypodiaceae. We recorded an inverse relationship among precipitation and the quantity and diversity of pollen grains and fern spores. The angiosperm and gymnosperm taxa showed the greatest recorded grains throughout the sampling year with respect to the species mentioned herewith, which have been reported as allergenic in various aerobiological studies.

Se realizó un monitoreo de la atmosfera del área urbana de Medellín, con el objetivo de identificar polen y esporas que se transportan por el aire a lo largo del año. El muestreo se realizó entre febrero de 2010 y marzo de 2011. Las muestras de polen y esporas aéreas se obtuvieron utilizando un captador volumétrico de succión tipo Hirst. En el trabajo se registraron 62 tipos polínicos y esporas, de las cuales 30 corresponden a angiospermas, dos a gimnospermas, 10 a pteridofitos y 20 a hongos. Las familias con mayor número de individuos por muestreo fueron: Oleaceae, Poaceae, Cyperaceae, Chenopodiaceae y Polypodiaceae. Se observó una relación inversamente proporcional entre la cantidad y diversidad de granos de polen y esporas de helechos encontrados, con respecto a la precipitación a lo largo del muestreo. Los taxones de angiospermas y gimnospermas que mayor cantidad de granos aportaron en los conteos durante el año de muestreo, corresponden a especies introducidas, con reportes de alergenicidad.

The mangrove killifish (Kryptolebias marmoratus) is the only vertebrate known to be capable of self-fertilization. Its gonad is typically an ovotestis that simultaneously produces eggs and sperm, and fertilization is internal. Although most populations of this species consist primarily or exclusively of hermaphroditic individuals, gonochoristic males occur at Ϸ20% frequency in a natural population at Twin Cays, Belize. Here we use a battery of 36 microsatellite loci to document a striking genetic pattern (high intraspecimen heterozygosities and low within-population linkage disequilibria) that differs qualitatively from the highly homozygous (or ''clonal'') genetic architecture characteristic of killifish populations previously studied in Florida, where males are much rarer. These findings document that outcrossing (probably between gonochoristic males and hermaphrodites) is common at the Belize site, and, more importantly, they demonstrate the dramatic impact that functional androdioecy can have on the population genetic architecture of this reproductively unique vertebrate species.A ndrodioecy is a rare reproductive system in which a natural population consists of functional males and hermaphrodites but no true female gonochorists. Previously known only in a few plants (1-10) and invertebrate animals (11-15), androdioecy has also evolved independently in a vertebrate species: the mangrove killifish, Kryptolebias (formerly Rivulus) marmoratus. Most surveyed populations of K. marmoratus consist primarily or exclusively of hermaphroditic individuals, but gonochoristic males are observed occasionally, and recent genetic evidence suggests that such individuals may mediate infrequent outcross events in this otherwise self-fertilizing species (16-18). The net result, documented most clearly for Florida locales (16), is a mixed-mating population genetic architecture consisting mostly of highly homozygous inbred strains (traditionally referred to as ''clones'') plus low percentages of highly heterozygous specimens stemming from recent outcross events. Thus, the genetic variety generated by outcrossing (16), and subsequently converted into new arrays of recombinant inbred lines upon resumptions of selfing, can significantly augment mutation and interlocality gene flow that formerly were thought to be the sole sources of ''clonal'' diversity in K. marmoratus (19)(20)(21).Gonochoristic males, which are phenotypically recognizable by coloration and histology, seem to be extremely rare in Florida (in our experience, Ͻ1% frequency among Ͼ1,000 individuals examined). However, in a collection from Twin Cays, Belize, made during 1988 and 1989, 53 males (18.8%) were present among 282 specimens surveyed (22). In laboratory-reared progeny from another collection (in 1991) of hermaphrodites from this Belize locale, segregating genetic variation was detected, a result interpreted to imply that natural outcrossing had occurred between males and hermaphrodites (17, 18).In this study, we use a battery of 36 microsatellite loci to exami...
