In contrast to the system of caste determination in most social insects, reproductive caste determination in some populations of Pogonomyrmex barbatus has a genetic basis. Populations that exhibit genetic caste determination are segregated into two distinct, genetic lineages. Same-lineage matings result in female reproductives, while inter-lineage matings result in workers. To investigate wheth...
Five novel herpesviruses were identified in suid species from Africa (common warthog, Phacochoerus africanus) and South-East Asia (bearded pig, Sus barbatus; babirusa, Babyrousa babyrussa) by detection and analysis of their DNA polymerase genes. Three of the novel species, P. africanus cytomegalovirus 1, P. africanus lymphotropic herpesvirus 1 (PafrLHV-1) and S. barbatus lymphotropic herpesviru...
The influence of environmental variables (oceanographic and climatic) on the catch rates striped red mullet (Mullus surmuletus) by artisanal fishery was investigated using different time series models (Dynamic Factorial Analyses; Min-Max Analyses Generalized Least Square models). Climatic oceanographic survey data were collected at areas Portuguese coast (Northwestern, Southwestern South-Algarv...
The concentration of diterpenes barbatusin (1) and 3β-hydroxy-3-deoxybarbatusin (2) in the extracts from leaves of Plectranthus grandis, P. barbatus, P. ornatus, and P. amboinicus was evaluated by HPLC-DAD analysis on a Luna C-18 column, using isocratic mixtures of water and acetonitrile as eluents. The regression equations were obtained with good linearity (r2 > 0.99) and limit of quantificati...
In many animal species, the propensity for aggression is linked to social context. In social insects, aggressive interactions between colonies are related to the assessment of cuticular hydrocarbon profiles. We investigated how, in the red harvester ant, Pogonomyrmex barbatus, an individual ant's task environment contributes to its hydrocarbon profile, and how task-specific differences in profi...
The present study deals with three species of Alpheus, including two new species, living symbiotically in burrows of innkeeper worms (Echiura: Thalassematidae) on the tropical coasts of the western Atlantic and eastern Pacific Oceans. Alpheus christojferseni n. sp. is described on the basis of four specimens from Atol das Rocas, northwestern Brazil, and one specimen from Bocas del Toro, Caribbe...
