Associação entre abelhas-sem-ferrão (Hymenoptera: Apidae: Meliponina) e Aetalion reticulatum (L.) (Hemiptera: Aethalionidae) em plantio de açaí-de-touceira. Repositório Alice
SANTOS, R. S.; PERUQUETTI, R. C.; MELO, G. A. R. de; SILVA, W. da; VASCONCELOS, A. da S.; AZEVEDO, T. da S..
Aetalion reticulatum (L.) (Hemiptera: Aethalionidae), conhecida popularmente por cigarrinha-das-frutíferas, cigarrinha-dos-pomares ou cigarrinha-dopedúnculo, é um inseto fitófago, cujas ninfas e adultos atacam diferentes espécies vegetais. Em março de 2014, no Campo Experimental da Embrapa Acre, foi observada a associação entre abelhas-sem-ferrão e colônias de A. reticulatum em cachos de açaí-de-touceira (Euterpe oleracea Martius).

Coastal phytoplankton community dynamics and coexistence driven by intragroup density-dependence, light and hydrodynamics ArchiMer
Barraquand, F.; Picoche, C.; Maurer, Daniele; Carassou, L.; Auby, Isabelle.
Phytoplanktonic communities maintain a high diversity in a seemingly homogeneous environment, competing for the same set of resources. Many theories have been proposed to explain this coexistence despite likely competition, such as contrasted responses to temporal environmental variation. However, theory has developed at a faster pace than empirical evaluation using field data, which requires inferring drivers of community dynamics from observational time series. Here, we combine autoregressive models with a data set spanning more than 20 years of phytoplankton counts every two weeks, together with nutrients and physical variables. By comparing models dominated by nutrients or physical variables (hydrodynamics and climate), we first explore which abiotic...

Interaction of Acidithiobacillus ferrooxidans, Rhizobium phaseoli and Rhodotorula sp. in bioleaching process based on Lotka-Volterra model Electron. J. Biotechnol.
Zheng,Xuecheng; Li,Dongwei.
Background: Nowadays, leaching-ore bacteria, especially Acidithiobacillus ferrooxidans is widely used to retrieve heavy metals, many researches reflected that extra adding microorganism could promote bioleaching efficiency by different mechanisms, but few of them discussed the interaction between microorganisms and based on growth model. This study aimed to provide theoretical support for the collaborative bioleaching of multiple microorganisms by using the Lotka-Volterra (L-V) model. Results: This study investigated the interaction of Acidithiobacillus ferrooxidans, Rhizobium phaseoli,and Rhodotorula sp. Results showed that the individual growth of the three microorganisms fit the logistic curves. The environmental capacities of A. ferrooxidans, R....

Introduced herbivores and the Allee effect in animal-pollinated plants Ecología austral
Vázquez,Diego P.
Interspecific interactions can be modulated by the community context in which they occur. In this paper I focus on plant-pollinator interactions and their modulation by introduced herbivores through changes in plant population density. I first develop a mathematical model that relates the population density of an animal-pollinated plant species with pollinator visitation frequency, pollination, reproduction and per capita growth rate. This model allows me to investigate how several pollination-related parameters -including relative abundance of the focal plant species, pollinator specialization, pollination quantity and quality and pollen limitation of reproduction- influence the relationship between per capita growth rate and population density. I then...

New observations on scleractinian corals from Indonesia: 2. Sipunculan-associated species belonging to the genera Heterocyathus and Heteropsammia Naturalis
Hoeksema, B.W.; Best, M.B..
Three Indonesian species of Heterocyathus and two of Heteropsammia are briefly diagnosed. Remarks are given on their synonymy, phenotypic variation, and ecology. All five species are found on soft substrata in the proximity of coral reefs and live in association with a sipunculan worm. This interspecific assocation is discussed with regard to whether it is mutualistic or parasitic.

Pollination and other biotic interactions in figs of Ficus eximia Schott (Moraceae) Rev. Bras. Bot.
PEREIRA,RODRIGO AUGUSTO SANTINELO; SEMIR,JOÃO; MENEZES JR.,AYRES DE OLIVEIRA.
During the period from 1992 to 1997, interactions of several organisms and Ficus eximia figs, a monoecious species, were studied in plants located in Campinas/SP and Londrina/PR (Brazil). Ficus eximia is pollinated by a single fig wasp species, Pegoscapus sp. (Hymenoptera: Agaonidae, Agaoninae), but also visited by other 14 non-pollinating wasps (Agaonidae, Eurytomidae, Torymidae). Mites (Tarsonemidae), nematodes (Diplogasteridae) and fungi which use the body of the pollinating fig wasp to disperse themselves were also observed.

Pollination and seed dispersal by lizards: a review RChHN
GODÍNEZ-ALVAREZ,HÉCTOR.
This paper reviews the ecological literature published during the last 15 years on pollination and seed dispersal by lizards, in order to determine the possible effects of these animals on plant reproduction. This review is only limited to these years because articles on plant-lizard interactions during this period have used more rigorous experimental approaches than those made previously. All compiled data were analyzed considering the conceptual framework provided by the quantity and quality components of pollination and seed dispersal (i.e., effectiveness), since this information is essential to have an idea of the relative contribution of animals to plant fitness. Results showed that 34 species of lizards feed on nectar and fruits of plants. While...

Uma espécie nova de Schwarzula da Amazônia (Hymenoptera, Apidae, Meliponini) Iheringia, Sér. Zool.
Camargo,João M. F.; Pedro,Silvia R. M..
Schwarzula coccidophila sp. nov., a tiny Amazonian stingless bee, that attends scale insects (Cryptostigma Ferris, 1922, Coccidae) in its nest, is described. It is distinguished from Schwarzula timida (Silvestri, 1902), the only other species of the genus, mainly by the malar area longer than diameter of 3rd flagellomere, and the denser plumose pilosity. Additional records of S. timida is presented.
