Analyse et modélisation des évolutions à long terme de la biodiversité phytoplanctonique dans les zones côtières sous l’effet des pressions environnementales et anthropiques ArchiMer
Hernandez Farinas, Tania.
Coastal areas are highly-dynamic systems exposed to the effect of climate variations and human impacts, influencing the community diversity. In these ecosystems, the phytoplankton constitutes the base of food webs and integrates the effects of global changes and quality variations of coastal waters. In this context, the general objective of this study was to assess the long-term changes in the diversity of phytoplankton communities in coastal waters at different dcales and levels of organisation. Firstly, the data collected by the Phytoplankton and Phycotoxin Monitoring Network from the IFREMER was examined to study the temporal variations of the assemblages within the last two decades along the French coast and to assess the relationship with the...

Estrutura sinusial dos componentes herbáceo e arbustivo de uma floresta costeira subtropical Rev. Bras. Bot.
MÜLLER,SANDRA CRISTINA; WAECHTER,JORGE LUIZ.
As sinúsias herbáceas e arbustivas são componentes de comunidades florestais pouco pesquisados nas regiões tropicais e subtropicais. Neste trabalho foram estudadas a composição florística e a estrutura fitossociológica destas sinúsias em uma floresta arenosa (restinga) da Planície Costeira do Rio Grande do Sul, Brasil. Os dados fitossociológicos foram obtidos em 30 parcelas de 2 x 2 m. Em cada parcela anotou-se a presença e a altura máxima das espécies herbáceas e arbutivas, e a cobertura foi estimada pela escala de Causton. A composição florística total da área compreende 61 espécies, 52 gêneros e 33 famílias. As famílias que apresentaram mais de duas espécies foram: Poaceae, Commelinaceae, Orchidaceae, Piperaceae, Rubiaceae e Asteraceae. As formas de...

Floristic diversity of two crystalline rocky outcrops in the Brazilian northeast semi-arid region Rev. Bras. Bot.
Gomes,Polyhanna; Alves,Marccus.
Floristic composition and structure of vegetation were studied in two rocky outcrop areas in the semi-arid region of northeastern Brazil. From April 2007 to September 2008, 18 monthly field trips were carried out. Vascular plants were randomly collected throughout the outcrop areas. For structural analysis, 30 plots of 1 × 1 m were set in the vegetation islands. The checklist presented combines 211 species (69 families and 168 genera), although only 56 species were collected in the plots. Fabaceae (18 spp.; 8.5%), Asteraceae (17 spp.; 8%), Orchidaceae (13 spp.; 6.1%), Euphorbiaceae (13 spp.; 6.1%), Bromeliaceae (10 spp.; 4.7%), and Poaceae (eight spp.; 3.8%) are the richest families. Overall, 1,792 shrub and herbaceous specimens were counted in the plots....

Root fungal associations in some non-orchidaceous vascular lithophytes Acta Botanica
Muthukumar,Thangavelu; Chinnathambi,Marimuthu; Priyadharsini,Perumalsamy.
ABSTRACT Plant roots in natural ecosystems are colonized by a diverse group of fungi among which the most common and widespread are arbuscular mycorrhizal (AM) and dark septate endophyte (DSE) fungi. Though AM and DSE fungal associations are well reported for terricolous plant species, they are rather poorly known for lithophytic plant species. In this study, we examined AM and DSE fungal association in 72 non-orchidaceous vascular plant species growing as lithophytes in Siruvani Hills, Western Ghats of Tamilnadu, India. Sixty-nine plant species had AM and 58 species had DSE fungal associations. To our knowledge, we report AM fungal association in 42 and DSE fungal association in 53 plant species for the first time. There were significant differences in...
