ABNORMAL SPERMATHECAE NUMBERS IN PERUVIAN SANDFLIES (DIPTERA: PSYSCHODIDAE)

We report and illustrate two abnormal spermatheca numbers found in Peruvian sandflies, a supernumerary spermatheca in Lutzomyia cernerai and the absence of one spermatheca in L. amazonensis.

Wood specific gravity of trees and forest types in the southern Peruvian Amazon

Estimates of terrestrial biomass depend critically on reliable information about the specific gravity of the wood of forest trees. The study reported on here was carried out in the southern Peruvian Amazon and involved collection of wood samples from trees (70 spp.) in intact forest stands. Results demonstrate the high degree of variability in specific gravity (ovendry weight/green volume) in trees at single locations. Three forest types (swamp, high terrace forest with alluvial soil, and sandy-soil forest) had values close to the average reported for tropical forest woods (.69). Two early successional forest types, which make up as much as 12% of the total vegetated area in this part of the Amazon, had values significantly lower (.40). An increase in specific gravity with increasing age of the tree, which has been reported in some spe cies of tropical-forest woods, is seen in a positive relationship between specific gravity and di ameter for a species prevalent in one plot. Increases in specific gravity with tree and forest age may be significant in estimating changes in carbon stores over time.

Dispersal of seeds of Hymenaea courbaril (Fabaceae) in a logged rain forest in the Peruvian Amazonian

Seed dispersal of Hymenaea courbaril was studied by following the fate of 585 seeds embedded with small magnets and set in displays in and near a logged strip in rain forest in the Peruvian Amazonian. Mammals took fruits from all displays, which were located in the forest, edge, and cleared strip. Overall removal rates were low - a median of 8.1 fruits / month from displays maintained with 8-10 fruits - but were higher in August than in earlier months. Most fruits were dropped near the display or had their seeds eaten, but > 13% were successfully dispersed. Most of the dispersed seeds were buried, which increases probability of germination. Maximum dispersal distance of live seeds was 12.1 m (median 3.1 m), but other magnets were transported up to 34 m, indicating seeds were dispersed further, but then eaten. Acouchies (most likely Myoprocta pratti) and agoutis (Dasyprocta fuliginosa) were apparently the main dispersal agents. Dispersal of seeds from the forest into the logged strip was rare, suggesting that although rodents disperse H. courbaril, they cannot be relied on for the reseeding this and similar species in recent clearings.

The parasitism of Ixodes luciae (Acari: Ixodidae) on marsupials and rodents in Peruvian Amazon

In this work the infestation with I. luciae on Didelphimorphia and Rodentia in different environments of Peruvian Amazon was studied. Didelphimorphia was represented by the family Didelphidae. Specimens belonging to Caluromys lanatus, Didelphis marsupialis, Marmosops sp.2, Metachirus nudicaudatus, Philander andersoni and Philander opossum were infested with adults I. luciae and one Micoureus sp. was infested with larvae. In Rodentia, the infestation with I. luciae nymphs was restricted to Hylaeamys perenensis, Hylaeamys yunganus and Oligoryzomys microtis, while one Oecomys bicolor (all Cricetidae) was infested with larvae of this species. The few larvae were found on rodents captured in primary forest. The only significant difference (P < 0.05) in prevalence of adult ticks on Didelphimorphia was between P. andersoni and M. nudicaudatus (chi-square distribution). Adult tick distribution was significant different in P. andersoni in comparison with M. nudicaudatus, P. opossum and D. marsupialis (Kruskal-Wallis test). No significant effect of month or environment was detected in relation to adult tick infestation on Didelphimorphia. The prevalence of nymphal infestation as well as tick distribution showed that H. perenensis and H. yunganus were significantly more prone to be infested with nymphs of I. luciae than O. microtis. Prevalence of nymph infestation was higher in primary and secondary forest than rural areas while abundance was higher in secondary forest when compared with rural areas (P < 0.05). Kruskal-Wallis test showed differences (P < 0.05) for nymphal infestation during December in relation to January, March, April and June. The natural cycle of I. luciae appeared to be continuous, bound to adult tick infestation on Philander and nymphal infestation on Hylaeamys in forested environs.

Direito, indústria e sociedade: os diferentes olhares sobre a comunicação autoral no cinema

O artigo que nos propomos apresentar tem como objetivo expor duas das temáticas principais que se Inserem na investigação a ser realizada no âmbito do Doutoramento em Ciências da Comunicação, denominada “Autoria Coletiva e a Comunicação da sua Arte: A Disparidade entre a Visão Legal e Social do Cinema e da sua Indústria”. Os temas selecionados foram a noção de originalidade e de autoria no cinema, do ponto de vista legal, social e industrial, sendo levantadas algumas questões e conclusões que continuarão a ser investigadas. Como metodologia de investigação, foi feita uma análise do Código do Direito de Autor e dos Direitos Conexos e de investigações feitas dentro deste domínio. Iremos focar-nos maioritariamente no sistema jurídico nacional, sendo utilizado como sistema de comparação o caso americano que se regem pelo Copyright. Serão mencionadas várias obras fílmicas, não só obras finalizadas mas também o processo da sua execução (making-off), de forma a dar a conhecer que tipo de intervenção cada elemento de uma produção tem nu m filme, a partir da própria obra.

A paisagem (urbana) no cinema. Um último plano de leitura

(Excerto) «O jardim familiar (primeira fase do abandono): montões informes de silvedo, buxo descabelado, urtigas, flores selvagens. As palmeiras de pouco porte incharam tanto que fazem pensar em anões velhos, doentes, com as suas cabeleiras, as suas folhas emaranhadas, caindo em arco até ao chão». Assim se abre o convite de Carlos de Oliveira a uma deambulação por entre o interior-exterior de uma paisagem que a todo o instante se inventa. Sobre as memórias, os lugares, erguem-se dunas, vozes, intensidades de luz e passos que negrejam. São infinitos os modos de descrever uma paisagem... mas o que é, antes de mais, a paisagem? Admite-se que os seres humanos, confrontados coma natureza, tenham desde logo encetado uma íntima relação com o mundo do visível. Porém, uma tal «visão», motivada pelo reconhecimento do carácter vital da natureza, não implica necessariamente uma «experiência estética», resultante dos efeitos do universo exterior sobre o olhar. Na verdade, impõe-se uma certa distância como condição de possibilidade e de transformação subjectiva do território em paisagem. Nascida da percepção individual, a construção da «paisagem» funda-se num impulso fusional com um lugar que se torna estrangeiro e, desse modo, objecto de reflexão.
