| マニュアスプレッダで散布された堆肥の乾物質量と窒素投入量の圃場内分布を評価するために，３つの 圃場で散布試験を実施した。供試堆肥の含水率は平均で５３～８１％と圃場ごとに大きな差異が見られ，その 変動係数はB とC 圃場が４．６％以内であったのに対し，A 圃場は９．４％以上とばらつきが大きかった。バー ク堆肥の窒素含有量は牛ふん堆肥に比べると少なく，その平均はA 圃場で１４．７g／kg, C 圃場で１６．８g／kg であった。圃場全体の堆肥の散布量と窒素投入量の変動係数はいずれの圃場でも４９％以上とばらつきが大 きかった。しかし，堆肥の含水率の変動が少ない圃場では，堆肥の現物質量と窒素投入量の分布形状がほ ぼ一致することから，圃場内の窒素投入量を均一にするためには，堆肥水分のばらつきを少なくし，かつ 堆肥散布精度を向上させることが必要であると考える。 In order to evaluate distribution variability of the dry weight and the amount of nitrogen input of the compost applied with manure spreaders, the experiments of compost application were carried out in three fields. The mean values of compost moisture content at three experimental fields range from 53 to 81%, and their differences between three fields were significant. The... |

| Fifty-six villages along the coast of the State of Paraíba, Brazil, were visited to determine and map the occurrence of Amazona amazonica (Linnaeus, 1766). Search was conducted with binoculars and the residents of each locality were interviewed using a questionnaire to obtain information about the occurrence and species´s biological data. Reports of recent and old occurrences, absence and feeding areas were registered. The food items mentioned were fruits, such as cashew, cashew nuts, palm oil, and agricultural products, such as corn. The reproductive period occurred between November and December. Breeding sites were mangrove areas and coconut trees, with nests being made in tree hollows. Questionnaires helped to elaborate a distribution map of the... |

| This paper presents a review of the geographical distribution of Chiasmocleis albopunctata (Boettger, 1885), based on data from literature, scientific collections, and field notes. Our reviewing significantly enlarges the distribution of the species within the Brazilian territory, with new records for the states of Bahia, Maranhão, and Tocantins. Among all species of the genus, C. albopunctata can be considered the one with the widest latitudinal and altitudinal ranges, as well as greater environmental plasticity. |
