6. Movement patterns and home range in Diplomystes camposensis (Siluriformes: Diplomystidae), an endemic and threatened species from Chile
ABSTRACT We document movement patterns and home range of Diplomystes camposensis, an endemic and threatened freshwater catfish from Chile. We tracked the movements of seven individuals of different body size (13.5 to 19 cm SL) using portable radio telemetry equipment to investigate movement patterns in relation to day/night activity and habitat use in the Sa

7. Pyriproxyfen and the microcephaly epidemic in Brazil - an ecological approach to explore the hypothesis of their association
The microcephaly epidemic in Brazil generated intense debate regarding its causality, and one hypothesised cause of this epidemic, now recognised as congenital Zika virus syndrome, was the treatment of drinking water tanks with pyriproxyfen to control Aedes aegypti larvae. We present the results of a geographical analysis of the association between the preva

8. The spatiotemporal trajectory of a dengue epidemic in a medium-sized city
Understanding the transmission dynamics of infectious diseases is important to allow for improvements of control measures. To investigate the spatiotemporal pattern of an epidemic dengue occurred at a medium-sized city in the Northeast Region of Brazil in 2009, we conducted an ecological study of the notified dengue cases georeferenced according to epidemiol

9. Habitat use and movements of Glossophaga soricina and Lonchophylla dekeyseri (Chiroptera: Phyllostomidae) in a Neotropical savannah
The greatest current threat to terrestrial fauna is continuous and severe landscape modification that destroys and degrades animal habitats. This rapid and severe modification has threatened species, local biological communities, and the ecological services that they provide, such as seed dispersal, insect predation, and pollination. Bats are important polli

10. Use of space by the Neotropical caviomorph rodent Thrichomys apereoides (Rodentia: Echimyidae)
The objective of this study was to investigate some parameters of the space use by individuals in a population of the hystricognath rodent Thrichomys apereoides (Lund, 1839), using the spool-and-line tracking technique. This technique is useful for investigating characteristics of habitat use by individuals since it allows the mapping of the places where the

11. Área de uso e seleção de habitats por veado-catingueiro (Mazama gouazoubira; Fisher, 1814) no Pantanal de Nhecolândia-MS / Area of use and habitat selection by brown brocket deer (Mazama gouazoubira, Fisher, 1814) in the Nhecolândias Pantanal-MS
The physique space is a major dimensions of the niche of a species as the way is used for determining a series of interactions with the ecological environment. In the present study we estimated the size of the home range and habitat selection considering two scales of selection (second and third order) by brown brocket deer (Mazama gouazoubira) in the sub-re

12. Padrões de distribuição de mamíferos de médio e grande porte em paisagens fragmentadas / Distribuition patterns of medium and large size mammals in fragmented landscapes
Habitat fragmentation is defined as the breaking of a continuous habitat in patches or fragments. This process leads to environmental changes capable of affecting communities in different ways, causing species composition changes. Beta diversity measures can show the variation between the composition of different communities, where two ecological patterns ca
