Marine algal flora of Santa Maria Island, Azores
Este artículo contiene 41 páginas, 4 tablas, 15 figuras.Background
The algal flora of the Island of Santa Maria (eastern group of the Azores archipelago) has
attracted interest of researchers on past occasions (Drouët 1866, Agardh 1870, Trelease
1897, Schmidt 1931, Ardré et al. 1974, Fralick and Hehre 1990, Neto et al. 1991, Morton
and Britton 2000, Amen et al. 2005, Wallenstein and Neto 2006, Tittley et al. 2009,Wallenstein et al. 2009a, Wallenstein et al. 2010, Botelho et al. 2010, Torres et al. 2010,

al. 2017, Parente et al. 2018). Nevertheless, the Island macroalgal flora is not well-known
as published information reflects limited collections obtained in short-term visits by
scientists. To overcome this, a thorough investigation, encompassing collections and
presence data recording, was undertaken at both the littoral and sublittoral levels down to a
depth of approximately 40 m, covering an area of approximately 64 km . The resultant
taxonomic records are listed in the present paper which also provides information on
species ecology and occurrence around the Island, improving, thereby, the knowledge of
the Azorean macroalgal flora at both local and regional scales.
New information
A total of 2329 specimens (including some taxa identified only to genus level) belonging to
261 taxa of macroalgae are registered, comprising 152 Rhodophyta, 43 Chlorophyta and
66 Ochrophyta (Phaeophyceae). Of these, 174 were identified to species level (102
Rhodophyta, 29 Chlorophyta and 43 Ochrophyta), encompassing 52 new records for the
Island (30 Rhodophyta, 9 Chlorophyta and 13 Ochrophyta), 2 Macaronesian endemics
(Laurencia viridis Gil-Rodríguez & Haroun; and Millerella tinerfensis (Seoane-Camba)

Ochrophyta).This research was supported by several projects, expeditions and campaigns (see Funding

Marine algal flora of São Miguel Island, Azores
Este artículo contiene 52 páginas, 4 tablas, 15 figuras.Background
The macroalgal flora of the Island of São Miguel (eastern group of the Azores Archipelago)
has attracted the interest of many researchers in the past, the first publications going back
to the nineteenth century. Initial studies were mainly taxonomic, resulting in the publication
of a checklist of the Azorean benthic marine algae. Later, the establishment of the
University of the Azores on the Island permitted the logistic conditions to develop both
temporal studies and long-term research and this resulted in a significant increase on
research directed at the benthic marine algae and littoral communities of the Island and
consequent publications.
Prior to the present paper, the known macroalgal flora of São Miguel Island comprised
around 260 species. Despite this richness, a significant amount of the research was never
made public, notably Masters and PhD theses encompassing information regarding
presence data recorded at littoral and sublittoral levels down to a depth of approximately
40 m around the Island and the many collections made, which resulted in vouchers
deposited in the AZB Herbarium Ruy Telles Palhinha and the LSM- Molecular Systematics
Laboratory at the Faculty of Sciences and Technology of the University of the Azores.
The present publication lists the macroalgal taxonomic records, together with information
on their ecology and occurrence around São Miguel Island, improving the knowledge of the
Azorean macroalgal flora at local and regional scales.
New information
A total of 12,781 specimens (including some identified only to genus) belonging to 431 taxa
of macroalgae are registered, comprising 284 Rhodophyta, 59 Chlorophyta and 88
Ochrophyta (Phaeophyceae). Of these, 323 were identified to species level (212
Rhodophyta, 48 Chlorophyta and 63 Ochrophyta), of which 61 are new records for the
Island (42 Rhodophyta, 9 Chlorophyta and 10 Ochrophyta), one an Azorean endemic
(Predaea feldmannii subsp. azorica Gabriel), five are Macaronesian endemisms (the red
algae Botryocladia macaronesica Afonso-Carrillo, Sobrino, Tittley & Neto, Laurencia viridis
Gil-Rodríguez & Haroun, Millerella tinerfensis (Seoane-Camba) S.M.Boo & J.M.Rico,
Phyllophora gelidioides P.Crouan & H.Crouan ex Karsakoff and the green alga Codium
elisabethiae O.C.Schmidt), 19 are introduced species (15 Rhodophyta, two Chlorophyta
and two Ochrophyta) and 32 are of uncertain status (21 Rhodophyta, five Chlorophyta and
six Ochrophyta).This research was supported by several projects, expeditions and campaigns (see Funding
above) and lately by the project “ACORES-01-0145-FEDER-000072” funded the

Migrações internacionais: teorias, políticas e movimentos sociais International migrations: theories, policies and social movements
APRESENTAM-SE subsídios para o debate sobre políticas de migração internacional que já se estende para movimentos sociais de expressivos contingentes documentados e não-documentados nos principais países de destino. Recomendações de organismos internacionais defendem políticas migratórias em termos de direitos humanos e na supervisão de remessas, consideradas um dos aspectos positivos das migrações e auxílio no combate à pobreza dos países de origem. O contraponto com formulações teóricas sobre o fenômeno evidencia incoerências e inviabilidades dessas propostas se não forem articuladas com esforços para o desenvolvimento econômico e social dos países envolvidos.<br>THE TEXT presents arguments for the debate concerning international migration policies; this debate, nowadays, involve social movements of increasing number of documented and undocumented migrants in the main destination countries. International organisms recommend migration policies based on human rights and remittances, considered as a way of reducing poverty in origin countries. Nevertheless, considering theoretical approaches and recent mass movements we can argue about the viability of the propositions as well as the necessity of also considering the structural conditions for the development efforts in these countries as a fundamental manner of combating poverty and improving their level of life
