The aim was to study the recovery of degraded pasture with the introduction of Stylosanthes macrocephala e capitata cv. Campo Grande on Brachiaria decumbens cv. Basilisk evaluating the levels N-total in roots, biomass, area, and length, diameter and root levels of macro and micronutrients in the soil. The experiment was conducted in the municipality of Andradina, Sao Paulo State, Brazil. The experimental design was a randomized block design in a split-plot (with and without phosphorus), with four replicates, forming the following treatments: control Brachiaria decumbens (CB), partial desiccation with 1.5 L ha(-1) of glyphosate (DP), total desiccation with 3.0 L ha(-1) of glyphosate (TD); tillage (T), soil scarification (S); harrowing rome (H) and plowing + disking (PD). Treatments H and PD were sown by broadcasting and the other in the form of direct seeding. Recovery strategies of grazing signal grass showed significant differences between treatments only for the content of N-total, there were no differences in geometric characteristics of roots and root biomass. The contents of macro and micronutrients in the soil showed no significant differences between the strategies of recovery. Fertilization had a significant effect for P. The introduction of estilosantes Campo Grande accompanied by techniques such as drying and plowing + disking contributed to increases in the N-total levels in the root system. Forms of introduction of legumes did not change the soil chemical properties.

The use of gastropod shells by hermit crabs is determined by the availability of shells in the environment or through selection for size and volume. This study analyzed patterns in the use of shells by Dardanus insignis (Saussure, 1858). From January 1998 to December 1999, 386 individuals were collected from two islands at Ubatuba, Sao Paulo. The crabs were measured for cephalothoracic shield length (CSL) and wet weight (CWW). The gastropod shells occupied by hermit crabs were identified, and the shell aperture width (SAW), dry weight (SDW) and internal volume (STY) were measured. The relationships between the dimensions of the gastropod shell and the hermit crabs were evaluated by linear regression analysis. Among the 11 species of gastropod shells used by D. insignis, the most often used was Olivancillaria urceus (31%), followed by Strombus pugilis (22%) and Siratus tenuivaricosus (18%). The shell of O. urceus was used most probably due to its high availability on Couves and Mar Virado islands. The most significant biometric parameter was shell aperture width (F=18.231; p<0.0001), highlighting the importance of this variable for the shell choice by D. insignis at both sites.

The production of a dictionary always generates controversy about decisions to be taken by the lexicographer. They are based – a priori – in previous theoretical and methodological choices. What we mean by dictionary? Why making certain choices rather than others? How to reconcile (if there is a reconciliation) the different approaches to describe the lexicon? The objective here is to contribute with theoretical and methodological reflections related to the Juruna Lexicography (Yudjá), as well as for lexicographical studies camp. This text addresses critical points of dictionaries production processes – if we may so call it – the history of the act of making a dictionary, so we can discuss choices to be taken to the entries of verbs in the Juruna-Portuguese bilingual dictionary assembly provided as a long term project result, in which some collaborators are working, including community’s indigenous. The work contains sections that will raise historical and linguistic discussions about the compilation of a dictionary and how this act binds to the applicability for the subjects that use this instrument firming / mobilizer of the lexicon visions. The focus here will be to discuss the verbs entries in the Juruna dictionary (stemming), taking lexicographical history as a contributor to certain choices of dictionaries production nowadays, whether for mother tongue, for foreign language, specialized lexicons, semantic groups, and systematizations for languages that are starting/beginning a first publication of dictionaries

Fossil fuels are the main energy sources of the modern industrial age. Very sophisticated processes have been developed to extract these resources, due to increased demand on a global scale, as the extraction of oil. However, the complexity of these processes can cause accidents such as the release of oil to seas and oceans. In this context, this study proposes to carry out the implementation of a system of information to charts of environmental sensitivity to oil and prepare maps of vulnerability to oil for the city of Caraguatatuba-SP. The implementation of the database with geographical information of coastal environments was appropriate to be provided by the Internet, allowing wide access of data. The maps of vulnerability are important tool developed for the Individual Emergency Plans, because they were developed in operational scale, appropriate to actions to combat oil.
