          Abstract

          A new dwarf species of the centipede genus Ityphilus Cook, 1899, named I. donatellae sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae) is hereby proposed on the basis of specimens from the vicinity of Manaus, Central Amazonia (Brazil), previously identified as Ityphilus calinus Chamberlin, 1957 (hereby designated holotype female, paratype male and paratype female). Supplementary morphological data and new illustrations are provided after this type material. The new species, characterized by having the internal edge of the forcipular tarsungulum serrate, is herein included in a key that will enable the identification of the 10 other Neotropical members of the genus Ityphilus sharing the same trait. New distribution records and supplementary descriptive notes for Ityphilus crabilli Pereira, Minelli & Barbieri, 1994, and Ityphilus demoraisi Pereira, Minelli & Barbieri, 1995 (including the first description of the male of the latter), are also given. Undiluted 2-Phenoxyethanol (CAS No. 122-99-6) has been used as an effective clearing agent/mounting medium for the preparation of temporary mounts of all body parts of the examined specimens.

          Una nueva especie enana del género de ciempiés Ityphilus Cook, 1899, denominada I. donatellae sp. nov. (Chilopoda: Geophilomorpha: Ballophilidae), es aquí propuesta sobre la base de ejemplares provenientes de las cercanías de Manaus, Amazonia Central (Brasil), previamente identificados como Ityphilus calinus Chamberlin, 1957 (aquí designados holotipo hembra, paratipo macho y paratipo hembra). Datos morfológicos suplementarios y nuevas ilustraciones son provistos sobre la base de este material tipo. La nueva especie, caracterizada por tener el borde interno de la tarsungula forcipular serrado, es aquí incluida en una clave que permitirá la identificación de todos los miembros neotropicales del género Ityphilus que comparten el mismo carácter. Nuevos registros de distribución y notas descriptivas suplementarias para Ityphilus crabilli Pereira, Minelli & Barbieri, 1994, e Ityphilus demoraisi Pereira, Minelli & Barbieri, 1995 (incluyendo la primera descripción del macho de esta última) son también brindados. Se ha utilizado 2-Phenoxyethanol (CAS No. 122-99-6) no diluido, como un efectivo agente de diafanización (y a la vez medio de montaje), para la realización de preparaciones microscópicas transitorias de todas las partes del cuerpo de los especímenes examinados.

          Annual fluxes of carbon from deforestation and regrowth in the Brazilian Amazon.

          The distribution of sources and sinks of carbon among the world's ecosystems is uncertain. Some analyses show northern mid-latitude lands to be a large sink, whereas the tropics are a net source; other analyses show the tropics to be nearly neutral, whereas northern mid-latitudes are a small sink. Here we show that the annual flux of carbon from deforestation and abandonment of agricultural lands in the Brazilian Amazon was a source of about 0.2 Pg Cyr(-1) over the period 1989-1998 (1 Pg is 10(15) g). This estimate is based on annual rates of deforestation and spatially detailed estimates of deforestation, regrowing forests and biomass. Logging may add another 5-10% to this estimate, and fires may double the magnitude of the source in years following a drought. The annual source of carbon from land-use change and fire approximately offsets the sink calculated for natural ecosystems in the region. Thus this large area of tropical forest is nearly balanced with respect to carbon, but has an interannual variability of +/- 0.2 PgC yr(-1).
