Growth And Reproduction

Ants are one of the most influential elements in Australian ecosystems, having a major impact on plant growth and reproduction, and soil structure. They act as predators and competitors of other arthropods, and are an important food source for other animals. The book provides details on separating genera from those which are superficially similar and those which are commonly confused. The distribution, habitat preferences and general biologies of each genus are discussed, and there is an introduction to the more important research papers investigating each group.

Garcinia gardneriana (Clusiaceae) is a small to medium-sized tree that usually occurs on the floodplains of the Paraná River and it is an important food source for the local inhabitants. The fruit itself is consumed in natura, and juices and sweets are made from it. The purpose of this study was to describe morphological and structural aspects of fruits and seeds of this species in order to classify the fruit type and the pulpy layer which involves the seeds. The material analyzed consisted of ovary and fruits in different stages of development, collected from five plants from Aurélio Island, Baía River (MS, BR) and the description was done according to standard procedures in anatomy. The fruit is a yellowish-orange spherical berry ("bacóide" type). The smooth, coriaceous skin consists of the lignified exocarp. The endocarp cell layers are derived from the activity of an adaxial meristem that undergoes radial elongation. The edible sweet white pulp is formed by the endocarp, as well as the spongy mesocarp, in which the secretory ducts lose their function. The unitegmic anatropous ovules develop into anatropous exalbuminous seeds with a collapsed and undifferentiated testa. The embryo is hypocotylar. The features here described generally occur in Clusioideae-Garcinieae and Symphonieae.

The diet and feeding habits of the sharpsnout seabream, Diplodus puntazzo, from the Gulf of Gabès were investigated using stomach contents of 490 specimens ranging from 12.6 cm to 26.1 cm total length in size and from 29.95 g to 230.83 g in weight collected from commercial catches between April 2008 and March 2009. Of the total number of examined stomachs, 279 were empty (%VI = 56.94). This percentage varied significantly with months, attaining a maximum in spring (74.88%) and a minimum in autumn (37.38%). Eight major taxa were identified (Plantae, Spongia, Tunicata, Echinodermata, Crustacea, Annelida, Mollusca and Teleostei) in stomach contents of D. puntazzo. Plants were the most important food source, constituting 89.88% of the total Index of relative importance. The other groups, such as teleosts, molluscs, crustaceans and annelids represented accessory food. Significant differences in diet were observed in relation to season. Plants were the most important food source item in all seasons, especially during the autumn. The estimation of trophic level gave an average of 2.57 ± 0.2 for the whole population of D. puntazzo in the Gulf of Gabès. Based on the composition of its diet, this species may be considered as an omnivorous fish with a preference for vegetable material, and showing specialist feeding strategy.

Abstract Fish represents an important food source for people worldwide. Moreover, although considered a very old occupation, fishing continues to provide jobs, especially for the people living in the coastal countries. The quality of surface waters affects the quality of fish as a food source. For this reason, the present study aims to assess the quality of the ichthyofauna in the Oituz River and some of its tributaries using several parameters that have been computed based on the biometric data of the biological material gathered during 2004-2008, in correlation with the water pH and water temperature. The present paper also highlights some observations regarding the changes of the analyzed ecosystems, as well as some recommendations regarding the fish consumption in the studied basin, considered as a food source for humans.

Abstract Background: Allium sativum (garlic) is an economically important food source and medicinal plant rich in sulfides and other protective substances such as alliin, the precursor of allicin biosynthesis. Cysteine, serine and sulfur is the precursor of alliin biosynthesis. However, little is known about the alliin content under abiotic stress or the mechanism by which its synthesized. Results: The findings revealed that the content of alliin was lowest in the garlic roots, and highest in the buds. Furthermore, alliin levels decreased in mature leaves following wounding. Transcriptome data generated over time after wounding further revealed significant up-regulation of genes integral to the biosynthetic pathways of cysteine and serine in mature garlic leaves. Conclusions: The findings suggest that differential expression of cysteine, serine and sulfide-related genes underlies the accumulation of alliin and its precursors in garlic, providing a basis for further analyses of alliin biosynthesis.
