1. Phenology and dispersal syndromes of woody species in deciduous forest fragments of the Pantanal in Mato Grosso do Sul State, Brazil
ABSTRACT We analyzed the phenological responses of shrub-tree species of lowland deciduous (LDF) and submontane deciduous (SFD) forests in the Pantanal, and assessed their relationships with climatic factors at the community level and with strategies for seed dispersal. Vegetative and reproductive phenophases of 50 tree-shrub species were monitored monthly (

3. Glyphosate Applied at the Early Reproductive Stage Impairs Seed Production of Glyphosate-Resistant Hairy Fleabane
RESUMO: A buva [Conyza bonariensis (L.) Cronq.] resistente ao glyphosate é uma das principais plantas daninhas do mundo. Um dos fatores que fazem com que esta planta esteja amplamente distribuída nos mais diversos ambientes é sua alta capacidade de produção e dispersão de sementes. Plantas de buva não controladas pela aplicação de herbicidas rebrota

4. Liaisons dangereuses: cross-border gene flow and dispersal of insecticide resistance-associated genes in the mosquito Aedes aegypti from Brazil and French Guiana
BACKGROUND In recent years, South America has suffered the burden of continuous high impact outbreaks of dengue, chikungunya and Zika. Aedes aegypti is the main mosquito vector of these arboviruses and its control is the only solution to reduce transmission. OBJECTIVES In order to improve vector control it is essential to study mosquito population geneti

5. Consumption of Euterpe edulis fruit by wildlife: implications for conservation and management of the Southern Brazilian Atlantic Forest
Abstract: This study aimed to measure the wildlife consumption of Euterpe edulis fruit and use this data to discuss management possibilities. To estimate infructescence fruit volume consumed, collectors were installed in fruit-bearing palms. To characterize consumption from the ground, samples were placed next to fruiting palms. To identify wildlife and thei

6. Uncovering the spatial pattern of invasion of the honeybee pest small hive beetle, Aethina tumida, in Italy
ABSTRACT The fast tracking of invasion spatial patterns of alien species is crucial for the implementation of preventive and management strategies of those species. Recently, a honeybee pest, the small hive beetle Aethina tumida (hereafter SHB), has been reported in Italy, where it colonized more than 50 apiaries in an area of about 300 km2. SHB is a nest pa

7. Dispersal capacity of fruit fly parasitoid Diachasmimorpha longicaudata (Hymenoptera: Braconidae) in irrigated coffee plantations
ABSTRACT Diachasmimorpha longicaudata is an Old World parasitoid of tephritid fruit flies that was widely introduced in the Americas to control pest species such as the Mediterranean fruit fly Ceratitis capitata. Augmentative releases in irrigated coffee plantations in semiarid regions of Brazil are under consideration and dispersal capacity of D. longicauda

8. Evolution of seed dispersal in the Cerrado biome: ecological and phylogenetic considerations
ABSTRACT The investigation of the phylogeny of a group of organisms has the potential to identify ecological and evolutionary processes that have been occurring within a community. Seed dispersal is a key process in the life cycle of vegetation and reflects different reproductive strategies of plants to a set of ecological and evolutionary factors. Knowing t

9. Introducing the term 'Biocontrol Plants' for integrated pest management
Studies of interactions between crops, additional plants, pests and beneficial organisms already exist as well as studies of natural enemy preference, dispersal, and abundance. However, these studies focus on tri-trophic interactions from an "arthropod" point of view. We think that in order to optimize crop protection methods we need to understand the effect

10. A new look into the small-scale dispersal of free-living marine nematodes
We tested experimentally the hypothesis that prevailing locomotion/feeding strategies and body morphology may lead to more active dispersal of free-living marine nematodes, besides passive transport. Neutral Red was applied to the sediment inside cores and the red plume formed during the flood tide was divided into near, middle, and distant zones. At 0.5 m a

11. Estrutura e estratégias de dispersão do componente arbóreo em uma floresta estacional de encosta no Parque Estadual de Itapuã,sul do Brasil / Structure and dispersal strategies of the arboreal component in an hillside seasonal forest in Parque Estadual de Itapuã, southern of Brazil
Os objetivos do presente trabalho foram realizar uma análise exploratória da estrutura do componente arbóreo de uma floresta estacional de encosta, relacionando-a a variáveis ambientais, e avaliar os padrões bióticos nas síndromes de dispersão e estratégias de estabelecimento. O estudo foi conduzido no Parque Estadual de Itapuã, Viamão (RS), nas e

12. GENÉTICA, DISTRIBUIÇÃO E CONSERVAÇÃO DO GAVIÃO-REAL (Harpia harpyja) NO BRASIL
The harpy eagle occurs in the forests of the Neotropical region; it is widely distributed in Brazil where its occurrence has been principally registered in the Amazonian and Atlantic rainforests. Between these two biomes exists a corridor of open vegetation with forest connections where this species has also been registered. Brazilian forests have been drast
