Abstract:

Lauraceae is a large family of woody plants with high ecological and economic value. The tribal and generic division and phylogenetic relationship of Lauraceae have long been controversial. Based on morphological and molecular evidence, phylogenetic relationships within the Cinnamomeae, Laureae and Perseeae tribes, also called ‘the Core Lauraceae’, have arisen particular attention. In this review, we comprehensively collated the literatures on the phylogeny of Lauraceae published in recent years and summarized progress made in molecular systematic researches employing gene fragments, chloroplast genomes and DNA barcodings analyses. We clarified the phylogenetic relationships and main controversies of ‘the Core Lauraceae’, the systemic position of fuzzy genera (Neocinnamomum, Caryodaphnopsis and Cassytha) and the development of chloroplast genome and DNA barcodes. We further suggested and proposed the whole genome analysis and different inflorescence types would be possible to provide more information for further research on phylogenetic relationships and taxonomy of Lauraceae.

Abstract:

The diversity of secondary metabolites of individual plants results from multiple enzymatic processes in planta and various environmental factors, such as temperature, moisture, and soil conditions. Chemical composition analysis of plants can lead to a new method to understand relationship among comparable plants along with biological classification such as genetic and anatomical method. In this study, the chemical diversity of nine different Lauraceae species was investigated, and the plant samples were chemically analyzed and classified. Multivariate analysis methods, such as PLS-DA, were used to select important metabolites distinguishing the nine Lauraceae species. The selected metabolites were identified through preparative LC-MS or MS/MS fragment pattern analysis. In addition, the chemical dendrogram for the nine Lauraceae species was interpreted through molecular network analysis and compared with the genetic dendrogram. This approach enabled us to compare the complete chemical compositions of multiple plant samples to identify relationships among plants.

Abstract:

Abstract Ocotea is one of the largest genera in the Lauraceae (c. 400 spp.), and it has been known to be paraphyletic with respect to most other genera of the New World Lauraceae for almost 20 years. In the traditional circumscription, Ocotea contains not only Neotropical species, but also about 45 species from the African region, including Macaronesia, Madagascar, and the Comoro and Mascarene Islands. Only a few of the species have been included in previous molecular systematic analyses. Here we present a phylogenetic analysis, based on ITS and psbA-trnH sequences of 168 Lauraceae species, including 151 taxa from the Ocotea complex, among them 26 of the 45 Palaeotropical species currently placed in Ocotea. Our results show that the Old World species belong to two well-supported and morphologically distinguishable clades, one of which is placed unresolved among the Neotropical clades of the Ocotea complex, whereas the other is sister to Cinnamomum section Cinnamomum. The two clades can also be differentiated based morphologically. As a step towards a phylogenetic classification, we recognize the second group as the new genus Kuloa.

Abstract:

The goal of this work was to test if the macro and micro morphological analysis of the leaf surface could provide vegetative diagnostic characters for some of the most common Lauraceae species in Southern Brazilian Seasonal Forests. The leaf printing technique with universal instantaneous adhesive was used for the epidermical microscopical analysis and external macroscospical analyses of leave were made. Microscopic evaluation revealed the visibility and contours of anticlinal walls of epidermical cell and stomata and shape of guard-cells. Macroscopic evaluation showed the absence or presence of characters such as hairiness, domatia and scents. The results showed that analyzed characters, together with other diagnostic characteristics, could contribute in taxonomic delimitation of some common Lauraceae species in the Southern Brazil.

Abstract:

Lauraceae family has one of the highest values of importance in the Mixed Ombrophilous Forest (MOF). The commercial value of some of its species was a reason for intense forest exploitation in the southern region of Brazil. Considering the hypothesis that it provides an essential subsidy for the constitution of this forest type, the aim of this study was to identify and quantify the influence of Lauraceae family in the dynamics of a 15.2 ha MOF remnant. Census data were collected every three years, since 2007, in which all trees with a circumference at 1.3 m height equal to or greater than 30 cm were identified and measured. Dynamics were analyzed by periodic increment in diameter, recruitment, and mortality through the measurement periods, while cluster multivariate analysis and canonical correlation were applied for grouping species and assessing their importance on the forest remnant dynamics. Diameter distribution prognosis of Lauraceae and its species was obtained through a transition matrix. Eleven tree species of Lauraceae family were identified, which showed decreasing diameter distribution and value of importance equals to 9.51%. Using cluster analysis, five groups were obtained, while the canonical correlation of 0.551 was considered moderate and statistically significant by Wilks’ Lambda test. By the projection of diameter distribution, it was verified that the study community is stable and self-regenerative. Although it is considered moderate, the influence of family on the forest remnant tends to increase with the advance of ecological succession.

Abstract:

A Floresta Ombrófila Mista desempenha importante função social e ecológica na região Sul do Brasil. Embora tenha sofrido um profundo processo exploratório, resultando em sua fragmentação, apresenta elevado potencial para o manejo que, devidamente aplicado, favorece a conservação e recuperação de seus remanescentes. Com o objetivo de avaliar o incremento diamétrico e a dinâmica sucessional dessa fitofisionomia, foram empregados dados oriundos do estrato arbóreo (DAP ≥9,5 cm) de 10 parcelas permanentes de 1 ha cada, remedidas anualmente entre o período de 2000 a 2009, na Floresta Nacional de São Francisco de Paula, RS. As observações e projeções indicaram gradual redução da densidade da floresta, com destaque para a espécie Araucaria angustifolia (Bertol.) Kuntz., entretanto, observou-se tendência de aumento na densidade da família Lauraceae. O período de meia vida estimado para a floresta foi de 97 anos e, para Araucaria angustifolia, 332 anos. As estimativas ainda sugerem que, em 71 anos, as espécies de Lauraceae devem duplicar sua densidade. O crescimento da floresta foi inferior ao da família Lauraceae (= 0,175 cm/ano e = 0,179 cm/ano, respectivamente) e a Araucaria angustifolia manteve o menor crescimento (= 0,159 cm/ano). As análises indicaram um avanço sucessional, com a gradual substituição da Araucaria angustifolia por espécies com maior adaptação às condições de equilíbrio.Palavras-chave: Família Lauraceae; Floresta com Araucária; sucessão florestal. AbstractEcology and diametric projection of three arboreal groups in a Mixed Ombrophilous Forest fragment in São Francisco de RS, Brazil. The Mixed Ombrophylous Forest performs an important social and ecological function in southern Brazil. Although it has suffered a profound exploratory process, resulting in their fragmentation, it has a high potential for management that, properly applied, promotes conservation and recovery of their remains. In order to assess the increment in diameter and dynamics of phytophisiognomy, this research used data from the tree strata (DBH≥9.5 cm) of 10 permanent plots of 1 ha each remeasured annually between the period 2000 to 2009 in São Francisco de Paula National Forest, RS, Brazil. The observations and projections indicate a gradual reduction in the forest density, showing up Araucaria angustifolia (Bertol.) Kuntze species, however, for the Lauraceae species, there was a tendency of increase. The period of half-life estimated for the forest was 97 years and for Araucaria angustifolia, 332 years. The estimates also suggested that in 71 years, the Lauraceae should double its density. The forest growth was lower than that observed in the Lauraceae (=0.175 cm/year and =0.179 cm/year, respectively) and Araucaria angustifolia maintained the lowest growth (=0.159 cm/year). The analysis indicated a positive advance, with the gradual replacement of Araucaria angustifolia by other species with greater adaptation to the successional conditions. Keywords: Araucaria Forest; Lauraceae family; forest succession.
