What we thought would be a short, wrap-up visit to pick up our papers turned into two long days of bureaucratic back and forth. But frustration quickly turned into a sense of good fortune. While impatiently waiting for the per- mits, heavy rains had turned the roads into an impassible quagmire of clay. If we had left when first planned, we would have ended up worming our vehicle through a seemingly giant bowl of chocolate pud- ding. By the time we hit the roads they were dry enough so we negotiated easily around large trucks still deeply buried up to their axles—although, admittedly, we drove with the four-wheel drive engaged for most of the 300 kilometers to the Reserve’s overnight accommodations.

  • Breeding Biology of the White-Winged Nightjar (Eleothreptus Candicans) in Eastern Paraguay
    Revista Brasileira de Ornitologia, 22(2), 219-233 ARTICLE June 2014 Breeding biology of the White-winged Nightjar (Eleothreptus candicans) in eastern Paraguay Robert G. Pople Department of Zoology, University of Cambridge, Downing Street, Cambridge, CB2 3EJ, UK. Email: [email protected] Current address: BirdLife International, Wellbrook Court, Girton Road, Cambridge, CB3 0NA, UK. Received on 03 September 2013. Accepted on 02 October 2013. ABSTRACT: Breeding biology of the White-winged Nightjar (Eleothreptus candicans) in eastern Paraguay. I present the first detailed description of the breeding biology of the White-winged Nightjar (Eleothreptus candicans), based on data collected over three breeding seasons during 1998-2001 at Aguará Ñu, Canindeyú, eastern Paraguay. Male nightjars defended small territories situated on the upper slopes of ridgelines. Each territory contained one or more “display arenas” at which the male performed nuptial display flights. Aggregation indices confirmed that the primary display arenas of males were significantly clustered within the survey area. Within their territories, males apparently selected display arenas on the basis of their structural characteristics: mounds used as arenas were significantly lower and broader than random mounds. Males engaged in display activity from late August to early January. On average, males performed 0.54 ± 0.04 display flights per minute during nocturnal focal watches, but there was considerable intra-male variation in display rate. Following a burst of activity immediately after their arrival at display arenas at dusk, male display rate was best explained by ambient levels of moonlight. Males produced a previously undescribed insect-like “tik tik” call when inactive on their territories.

Aceito em 03.V.2010 RESUMO – As Arecaceae ou “palmeiras”, como são popularmente conhecidas, compreendem 207 gêneros e 2.675 espécies. Pouco é conhecido sobre sua história paleoecológica no extremo sul do Brasil, principalmente devido à difi culdade de separação das espécies no registro polínico. Para o Estado, é citada a ocorrência de 11 espécies, sendo que 9 são apresentadas neste trabalho contribuindo assim com dados inéditos desta família para o Rio Grande do Sul. A preparação dos grãos de pólen para posterior análise foi realizada através de acetólise. Fez-se descrição polínica dos grãos de pólen de Arecaceae baseado em seus atributos quanti e qualitativos. A análise morfológica das espécies mostrou grãos de pólen estenopolínicos, porém apresentando diferenças em relação ao tamanho e ornamentação, possibilitando o estabelecimento de quatro tipos polínicos. Através dos dados de distribuição e hábitat das espécies foi possível estabelecer correlação entre os tipos polínicos e o ambiente onde as plantas se desenvolvem. Palavras-chave: grãos de pólen, Palmae, morfologia polínica, Arecales. ABSTRACT – Pollen Difference in Butia, Euterpe, Geonoma, Syagrus and Thritrinax and paleoecological implications of Arecaceae for Rio Grande do Sul.

Fujii4 Department of International Biobusiness Studies, Graduate School of Agriculture, Tokyo University of Agriculture, 1-1-1 Sakuragaoka, Setagaya, Tokyo 156-8502, Japan. E, Mail: [email protected] (Received in revised form: May 25, 2018 ) ABSTRACT We evaluated the allelopathic potential of 239 Paraguayan plants using the sandwich method. The samples were collected from 3-different regions of Paraguay. A total of 130 species, 47 families were collected from (i). Botanical Garden and Zoo of Asunción and its surroundings, (ii). 71 species (40 families) from Mbaracayú Natural Reserve and (iii). 38 species (25 families) from the Chaco region. We found the species with high inhibitory potential, such as Cleome aculeata (Cleomaceae), which completely inhibited the germination of lettuce. Others spp. strongly inhibited the growth of lettuce seedlings viz., Strychnos brasiliensis (Loganiaceae), Pterogyne nitens (Fabaceae), Sorocea bonplandii (Moraceae), Rollinia emarginata (Annonaceae), Microstachys hispida (Euphorbiaceae), Prosopis ruscifolia (Fabaceae) and Senna sp. (Fabaceae). These results demonstrated high allelopathic potential of Paraguayan plant species. Key words: Allelopathy, Cleome aculeata, germination, lettuce, Paraguayan plants, Pterogyne nitens, sandwich method, seedling growth, Sorocea bonplandii, Strychnos brasiliensis. INTRODUCTION South America has rich biodiversity and is the centre of origin of several cultivated plants (19,47). Paraguay, also called “the heart of South America” due to its geographical location, also has rich flora and fauna (24,44).
