Avaliação do impacto de métodos florestais e de seca severa na população de coelho-bravo na mata nacional de Quiaios
No full textMestrado em Ecologia, Biodiversidade e Gestão de EcossistemasO papel determinante na cadeia trófica, faz do coelho-bravo (Oryctolagus
cuniculus) uma espécie chave dos ecossistemas ibéricos onde constitui a principal
presa de um vasto leque de predadores, alguns dos quais de elevado valor de
conservação. Este factor confere uma relevância ainda maior ao acentuado
declínio que esta espécie tem sofrido, na generalidade dos ecossistemas
mediterrânicos, provocado pela perda e fragmentação do seu habitat, por doenças,
predação e pressão cinegética excessiva. Neste trabalho efectuou-se o estudo e
caracterização das dinâmicas populacionais de coelho-bravo na Mata Nacional de
Quiaios, uma floresta costeira no centro de Portugal, incluída na rede Natura 2000.
Pretendeu-se por um lado, estudar o impacto de métodos florestais,
nomeadamente actividades de silvicultura preventiva contra o avanço de espécies
vegetais invasoras, e, por outro, o impacto de um período de seca severa nas suas
populações. Foram monitorizadas as populações de coelho-bravo duas vezes por
ano, Verão e Inverno, nas várias zonas preestabelecidas. A primeira época
estudada foi o Verão de 2002 e a última foi a de Inverno de 2008. A determinação
da abundância do coelho-bravo foi feita através da contagem de latrinas por
classes, ao longo de percursos predefinidos. Foram considerados os seguintes
biótopos: (i) zona de matos densos; (ii) zona de matos com baixa densidade de
acácia; (iii) zona de acacial; (iv) zona de limpeza mecânica de 2005; (v) zona de
limpeza mecânica de 2006; (vi) zona de pinhal esparso; (vii) zona de pinhal denso;
(viii) zona de duna. Os resultados obtidos confirmam os efeitos das limpezas
mecânicas, sugerindo, no entanto, um impacto diferenciado consoante a
metodologia aplicada. O método utilizado em 2005 foi mais agressivo e provocou
uma taxa de mortalidade mais elevada, enquanto que, o de 2006, apenas originou
o abandono do local. No que diz respeito ao efeito da seca, os resultados também
apontam no sentido do seu impacto nas populações dado que foram observadas
fortes diminuições coincidentes com o referido período. De salientar, ainda, que
este impacto dependeu do habitat estudado, dado que, em alguns dos biótopos,
como a duna e o acacial, não foram verificadas quebras na abundância. Este facto
deveu-se, provavelmente, ao tipo de vegetação dominante nestes habitats,
adaptada a ambientes secos, pelo que os períodos de seca não se devem reflectir
de forma tão evidente na disponibilidade alimentar. Este trabalho mostrou como
uma monitorização de coelho-bravo, utilizando metodologias simples e
económicas, pode constituir um importante contributo para uma mais correcta
gestão dos ecossistemas ibéricos.The determinant role in trophic chain, makes wild rabbit (Oryctolagus cuniculus) a
key species of Iberian ecosystems, being the main prey to a large number of
predators, some of which of great conservation value. This factor confers a higher
relevance to its marked decline observed on the majority of mediterranic
ecosystems, caused by habitat loss and fragmentation, and diseases, predation
and high hunting pressure. This work aimed to study and characterize the wild
rabbit population dynamics in Quiaios National Forest, a coastal forest in the centre
of Portugal included in a Natura 2000 network site. It was intended to study, in one
hand, the impact of forest practices, such as activities of preventive forestry against
the advance of invading species, and, in other hand, the impact of a severe drought
on populations. Wild rabbit populations were monitorized twice a year, Summer and
Winter, in predefined areas. Summer 2002 was the first studied season and Winter
2008 was the last. The determination of wild rabbit abundances was carried on
through latrine counts along the sampling transects. Several biotopes were defined:
(i) dense scrublands; (ii) scrublands with low densities of Acacia longifolia; (iii)
scrublands with high densities of Acacia longifolia; (iv) the 2005 intervention area;
(v) the 2006 intervention area; (vi) sparse pine forest; (vii) dense pine forest; (viii)
dune. The results confirm the effect of interventions suggesting, however, a
differentiated impact depending on the applied methodology. The 2005 intervention
was more aggressive provoking a higher mortality rate, while the 2006 intervention
only cause the area abandonment. Concerning drought effects, results also point
toward to an impact in populations given the strong reductions observed in its
abundance, coincident to that period. However, it has to be referred that this impact
showed to depend on the biotope, because in some of them, like dune and
scrublands with high densities of Acacia longifolia, decreases in species abundance
wasn’t detected. This fact is, probably, related with the dominant vegetation type of
those areas, adapted to dry environments, with lower effects on the rabbit’s food
availability. This work showed a how a wild rabbit monitorization, using simple and
economical methodologies, can provide reliable and comparable results that may
constitute an important contribute to a sustainable management of Iberian forest
areas

The trombone as portrayed in Portuguese iconography during the sixteenth and early seventeenth centuries
No full textThis article studies eleven sixteenth and seventeenth century iconographical sources depicting slide brass instruments, by both Portuguese and foreign artists active in Portugal, as well as foreign artists depicting Portuguese scenes. This study addresses questions concerning aspects of trombone technique that have not previously been considered and may have implications in the way the trombone was understood elsewhere in Europe. It focuses on aspects of technique depicted that may be representative of the trombone’s contemporary design and performance and therefore the manner in which the instrument was held and indeed played. Finally, this article suggests a transitional technical period when the way of holding the single-slide trumpet may have been used to play the trombone.Publisher PD
