Nematodes are among the most economically damaging parasites of bananas (Musa AAA) and plantains AAB). The restriction on use nematicides has encouraged development alternative strategies. This work aimed to study effects plantain banana lixiviate Pratylenchus coffeae Radopholus similis in vitro essay. P. R. were exposed four concentrations (5%, 15%, 25% 35%) each for 48 hrs. These compared wit...

Comolia ovalifolia DC Triana (Melastomataceae) and Chamaecrista ramosa (Vog.) H.S. Irwin and Barneby var. ramosa (Leguminosae-Caesalpinioideae) are tropical plant species found in restinga (herbaceous-shrubby, sandy costal ecosystems). They have flowers with poricidal anthers and are pollinated by bees. The study sought to analyse potential pollinators of both plants during visits to their flow...

The posterior light organ and eyestalk of the midwater shrimp, Sergestes similis Hansen, are capable of 140° of angular movement within the body during pitch body tilt, maintaining the organs at near horizontal orientations. Counter-rotations compensate for 74-80% of body inclination. These responses are statocyst mediated. Unilateral statolith ablation reduces compensation by 50%. There is no ...

Trichomonads are obligate anaerobes generally found in the digestive and genitourinary tract of domestic animals. In this study, four trichomonad isolates were obtained from carabao, dog, and pig hosts using rectal swab. Genomic DNA was extracted using Chelex method and the 18S rRNA gene was successfully amplified through novel sets of primers and undergone DNA sequencing. Aligned isolate seque...

An evaluation was made of the quality of samples of water and sediment collected from a series of reservoirs in the Tietê River (SP), based on limnological and ecotoxicological analyses. The samples were collected during two periods (Feb and Jul 2000) from 15 sampling stations. Acute toxicity bioassays were performed using the test organism Daphnia similis, while chronic bioassays were carried ...

Bu çalışmada, Konya Kapalı Havzası'nın en büyük sulak alanlarından birisi olan Akgöl-Ereğli Sazlıkları’nda ilk bilimsel kayıtların verildiği l925’ten günümüze kadar balık faunasındaki değişim irdelenmiştir. 1980’1i yılların başında yaklaşık 10 m derinlikte Akgöl, 1984’de İvriz Barajı'nın yapımından sonraki 5-6 yıl içinde hızla sığlaşmış; günümüzde tamamen kurumasının önüne geçmek için yapay bir...
