13. Técnicas de amostragem e a detecção de mamíferos terrestres na Floresta Amazônica.
Though used extensively the diurnal line-transect census method does not provide high quality information on the occurrence and abundance of many mammal species in the Amazonian forest, especially for larger and less abundant species. This study evaluated the effectiveness of diurnal line-transects with nocturnal line-transects and camera traps to detect ter

14. Manutenção de uma faixa de eucaliptos para proteção da borda de um fragmento florestal / Eucalyptus zone maintenance to protect a border of forestal fragment.
Eucalyptus zone maintenance to protect a border of forestal fragment. Nowadays, one of the biggest challenge found is the balance between the non tropical actions and the environment, this is called "sustentability". This work had as an objective values the influence of maintenance, during the forestal exploration of three lines of eucalyptus around one fore

15. Status conservacionista da mastofauna em fragmentos de Mata AtlÃntica Nordestina / Conservationist status of mammalls on atlantic forest fragments of brazilian northeastern
The aim of this study was to sample the medium and large sized mammalian fauna of the RPPN Frei Caneca and the surrounding area, comparing its abundance and diversity amongst four fragments of different sizes. The sample followed the Line Transect Method, when trails measuring between 1,3 and 2 km were established (depending on the size and shape of the frag

17. Spatial and temporal evaluation of water balance processes in a soil with citrus / Avaliação espaço-temporal de processos do balanço de água em um solo com citros
The objective of the present work was to quantify and characterize spatial and temporal variability of water storage, matric potential, water flux density and actual evapotranspiration in an oxisol cropped to citrus. The experimental plot consisted of two transects with 20 observation points in a spacing of four meters. Each observation point was located in

18. Razão de Poisson da crosta superior da região de Porangatu, Goiás, Província Tocantins: um estudo por refração sísmica
This work presents a refined seismic model of compressional waves (Vp) showing the distribution of Poisson ratio along the upper crust of central Tocantins Province, central Brazil, based on two dimensional modelling of the Porangatu seismic refraction data. The Porangatu seismic line begins in the Araguaia Belt (FXA) and continues through the western portio

19. Aerial line transect survey to estimate abundance of marsh deer (Blastocerus dichotomus) (Illiger, 1815)
A população de cervo-do-pantanal (Blastocerus dichotomus) está drasticamente reduzida no Brasil. O nosso objetivo foi o de estimar a abundância do cervo-do-pantanal na bacia do Rio Paraná e discutir a metodologia aplicada. Os resultados darão suporte para uma análise do impacto do enchimento da represa de Porto Primavera sobre essa população. Sessen

20. Diagnostic of game birds and mammals populations of Serra do Mar State Park, SP, Brazil. / Diagnóstico das populações de aves e mamíferos cinegéticos do Parque Estadual da Serra do Mar, SP, Brasil.
The aim of this work was to estimate the abundance, diversity and population size of game birds and mammals from the rain forest at Serra do Mar State Park (Parque Estadual da Serra do Mar - PESM), and to identify the variables which influence the ocurrence and distribution of those species. The PESM has 3.150 km2 and is the major continuous remaining of Atl

21. Anthonomus grandis Boheman (Coleoptera: Curculionidae) en la zona central y sur oeste de misiones, Argentina: polen como fuente alimenticia y su relación con el estado fisiológico en insectos adultos
Host feeding plants of adult boll weevils (Anthonomus grandis Boheman) were determined within the period: January 1997 - December 1999. This took place through the identification of pollen grains, isolated from the digestive tracts of boll weevils captured in pheromone traps placed in a transect line which passes through the localities of Montecarlo, San Ign

22. Distribuição espacial de aves em um fragmento florestal do campus da Universidade Estadual de Londrina, Norte do Paraná, Brasil
Spatial distribution of birds was studied in 10 ha forest fragment at Londrina State University, southem Brazil (23º15'S, 51º10'W). Five habitats were categorized in the forest fragment: four related to the edges and one related to the forest interior. A line transect, crossing ali these habitats, was used to identify the bird species one day each two week
