AN IMPROVED ENRICHMENT PROCEDURE FOR THE ISOLATION OF YERSINIA-ENTEROCOLITICA AND RELATED SPECIES FROM MILK
(Int Associação Milk Food Environmental Sanitarians, Inc, 1993-05-01)
A new enrichment procedure is proposed to improve the isolation of Yersinia enterocolitica and related species from milk. This procedure uses tryptic soy broth plus Polymyxin (5 IU/ml) and Novobiocin (10 mug/ml) - TSPN ...
Comparison of cheliped weight and growth in two species of crabs of the genus Callinectes (Brachyura, Portunidae)
(Inst Tecnologia Parana, 1998-01-01)
A comparison of the cheliped's weight in two species of the genus Callinectes was accomplished. The species C. danae e C. ornatus were collected by two otter trawl in Ubatuba bay (23 degrees 26' S and 45 degrees 02' W). ...
Leaf traits combinations may explain the occurrence of savanna herbaceous species along a gradient of tree encroachment
(2017-09-01)
In savanna environments, plants have specific leaf traits to deal with high irradiance. These traits allow plants to show high carbon assimilation capacity. However, under encroachment, reduced light availability may act ...
Testing the hypothesis of greater eurythermality in invasive than in native ladybird species: from physiological performance to life-history strategies
(WILEY-BLACKWELL, 2016)
Global warming and biological invasions are important threats to biodiversity. Nonetheless, there is little information on how these factors influence performance or life-history traits of invasive and native species. 2. ...
Thermal Tolerances of Three Tramp Ant Species (Hymenoptera: Formicidae)
(California State University, 2012-01-01)
Tramp ant species present a set of adaptations to their urban habitats, and there is a paucity of knowledge about how they interact with abiotic factors, like temperature. Temperature is well known to interfere with insect ...

Preliminary study of a methodology based on the degree-days concept for predicting the phenological phases of crops
(Fundacion Romulo Raggio, 1997-01-01)
This work develops a methodology (using the degree-days concept and linear regression), to forecast the duration of phenological phases in crops. An experiment was conducted in the greenhouse with three cultivars of cowpea ...
