Abstract Floristic surveys are the main source of information about species composition of different vegetation types and a fundamental input of information for biogeographical studies. Within the Caatinga Domain, there are many vegetation types, of which the most conspicuous is the deciduous caatinga s.s. vegetation. However, along the watercourses of this region, one can find a type of riparian forest called Carnaubais, characterized by a larger presence of evergreen species with access to underground water and a conspicuous occurrence of the endemic “carnauba” palm (Copernicia prunifera). The present study aimed at making a floristic survey on a Carnaubal riverine habitat and a nearby caatinga s.s. site in Ceará, and perform a biogeographical comparison with other sites within the Caatinga Domain. In our study site, we identified 186 species, distributed in 135 genera and 52 families. Of the 186 species recorded, we found 123 species uniquely in the caatinga s.s. phytophysiognomy, 40 uniquely in Carnaubal and 23 in both phytophysiognomies. The most representative families were Fabaceae (31 spp.), Poaceae (15 spp.), and Euphorbiaceae (13 spp.). The UPGMA and NMDS analyses supported the idea that the Carnaubal is a habitat with distinct flora within the Caatinga Domain.

Resumo O presente estudo teve como objetivo identificar a flora e a vegetação dos afloramentos rochosos isolados e de baixa altitude (lajedos), na vegetação de Caatinga Arbustiva Aberta, que se encontram nos municípios de Sobral, Groaíras e Santa Quitéria, no estado do Ceará, Brasil e propor uma classificação fitossociológica para estas comunidades xerófilas. Foram definidas cinco áreas de coleta de dados com elevada proporção de rochas expostas (> 80%) onde as excursões de campo decorreram em março de 2014 e 2015 (3º56’S e 40º23’W, 4º01’S e 40º05’W, 4º07’S e 40º08’W, 4º09’S e 40º09’W e 4º03’S e 40º00’W). No estudo da vegetação aplicou-se os métodos TWINSPAN (two-way indicator species analysis) e o clássico sigmatista de Braun-Blanquet. As áreas mínimas dos inventários fitossociológicos variaram de 8 a 16 m2. Foram coletadas as espécies vegetais que crescem em fissuras, fendas e ilhas de vegetação que se encontram em afloramentos rochosos. Foram registradas 88 espécies, distribuídas em 59 gêneros e 30 famílias botânicas. Fabaceae foi a família que se destacou em riqueza específica (20 spp.), seguida por Poaceae (dez spp.), Euphorbiaceae (sete spp.) e Convolvulaceae (seis spp.). Quanto ao endemismo foram registradas, em vegetação rupestre, 19 espécies endêmicas para o Brasil. Na análise fitossociológica da vegetação propôs-se estudar a comunidade de Pilosocereus gounellei (FA.C.Weber) Byles & Rowley e Encholirium spectabile Mart. ex Schult. & Schult.f. e a de Crateva tapia L. e Combretum leprosum Mart.

Abstract The present study was carried out to evaluate the chemical and pharmacological properties of the essential oil of Lavandula stoechas subsp. luisieri, which is a spontaneous shrub widespread in Alentejo (Portugal). Oxygenated monoterpenes, such as 1,8-cineole, lavandulol, and necrodane derivatives, are the main components of essential oil. It revealed important antioxidant activity with a high ability to inhibit lipid peroxidation and showed an outstanding effect against a wide spectrum of microorganisms, such as gram-positive and gram-negative bacteria and pathogenic yeasts. The analgesic effect studied in rats was dose dependent, reaching a maximum of 67 % at 60 min with the dose of 200 mg/kg and the anti-inflammatory activity with this dose caused an inhibition in carrageenan-induced rat paw oedema (83 %) that is higher than dexamethasone 1 mg/Kg (69 %). Besides, animals exhibited normal behaviour after essential oil administration, revealing low toxicity. The essential oil of L. luisieri from Alentejo presents important pharmacological properties and low toxicity, and is a promised candidate to be used as a food supplement or in pharmaceutical applications.

We review observational, experimental, and model results on how plants respond to extreme climatic conditions induced by changing climatic variability. Distinguishing between impacts of changing mean climatic conditions and changing climatic variability on terrestrial ecosystems is generally underrated in current studies. The goals of our review are thus (1) to identify plant processes that are vulnerable to changes in the variability of climatic variables rather than to changes in their mean, and (2) to depict/evaluate available study designs to quantify responses of plants to changing climatic variability. We find that phenology is largely affected by changing mean climate but also that impacts of climatic variability are much less studied, although potentially damaging. We note that plant water relations seem to be very vulnerable to extremes driven by changes in temperature and precipitation and that heatwaves and flooding have stronger impacts on physiological processes than changing mean climate. Moreover, interacting phenological and physiological processes are likely to further complicate plant responses to changing climatic variability. Phenological and physiological processes and their interactions culminate in even more sophisticated responses to changing mean climate and climatic variability at the species and community level. Generally, observational studies are well suited to study plant responses to changing mean climate, but less suitable to gain a mechanistic understanding of plant responses to climatic variability. Experiments seem best suited to simulate extreme events. In models, temporal resolution and model structure are crucial to capture plant responses to changing climatic variability. We highlight that a combination of experimental, observational, and/or modeling studies have the potential to overcome important caveats of the respective individual approaches.

We present the results of the ecology and variation in habitat of the orchid Serapias perez-chiscanoi Acedo, based on field studies between 2002 and 2007. The study area lies in the proximity of the small village of Vila Nova de Baronia, which is situated in the Lower Alentejo province (Portugal). The following climatophilous series of cork oak forest were identified: Asparago aphylli-Querceto suberis sigmetum and their subsequent stages: Phillyreo angustifoliae-Arbutetum unedonis, Halimio ocymoidis-Ericetum umbellatae and/or the community of Ulex australis subsp. welwitschianus and Cistus ladanifer and Trifolio cherleri-Plantaginetum bellardii. Typical communities of wet soils (Junco pygmaei-Isoetetum velati, Periballio laevis-Illecebretum verticillati, Loto hispidi- Chaetopogonetum fasciculati) and saturated soils (Myosotido stoloniferae-Ranunculetum omiophylli and the Juncus bulbosus and Myosotis lusitanica community) were found in depressions. S.perez-chiscanoi was found in the following plant communities: Junco pygmaei-Isoetetum velati, Loto hispidi-Chaetopogonetum fasciculati, Gaudinio fragilis-Agrostietum castellanae, and the community of Ulex australis subsp. Welwitschianus and Cistus ladanifer.

As comunidades anfíbias pioneiras da bacia hidrográfica do Rio Sado (Setor Mariânico-Monchiquense, Subprovíncia Luso-Extremadurense e Setor Ribatagano-Sadense, Subprovíncia Sadense-Divisório Portuguesa) foram objeto do presente estudo. Destacando-se a composição florística de cada fitocenose, bem como os dados referentes à sua ecologia, corologia e sintaxonomia, são apresentadas as principais comunidades vegetais anfíbias identificadas: Junco capitati-Isoetetum hystricis Braun-Blanquet 1936, Junco pygmaei-Isoetetum velati Rivas Goday 1956, Periballio laevis-Illecebretum verticillati Rivas Goday 1954, Loto subbiflori-Chaetopogonetum fasciculati Rivas-Martínez & Costa in Rivas-Martínez, Costa, Castroviejo & E. Valdés 1980, Hyperico elodis-Rhynchosporetum rugosae Neto, Capelo, J.C. Costa & Lousã in Neto 1997, Anagallido tenellae-Juncetum bulbosi Braun-Blanquet 1967, Utriculario exoletae-Sphagnetum auriculati Neto, Capelo, J.C. Costa & Lousã 1996 e Cirsio palustris-Juncetum rugosi Neto, Capelo, J.C. Costa & Lousã 1996). Este estudo mostrou que essas comunidades vegetais são, em sua maioria, relictos, com áreas de distribuição restritas e encontram-se fortemente pressionadas pela crescente ação antrópica e pelas alterações climáticas. Embora com características claramente atlânticas, foram sendo invadidas por espécies mediterrânicas, cujo domínio foi progressivamente aumentando desde o período Atlântico (7800-5700 B.P.), durante o qual se verificou o seu ótimo.
