On sampling collection procedure effectiveness for forest soil characterization

Castro, Ana Meira; Meixedo, João P.; Santos, Jorge; Góis, Joaquim; Gonçalves, António Bento; Vieira, António; Lourenço, Luciano

One of the most important measures to prevent wild forest fires is the use of prescribed and controlled burning actions as it reduce the fuel mass availability. The impact of these management activities on soil physical and chemical properties varies according to the type of both soil and vegetation. Decisions in forest management plans are often based on the results obtained from soil-monitoring campaigns. Tho...


Modifying fish gelatin electrospun membranes for biomedical applications: cross...

Padrão, Jorge; Silva, João P.; Rodrigues, Ligia R.; Dourado, Fernando; Lanceros-Mendez, Senentxu; Sencadas, Vitor

Development of suitable membranes is a fundamental requisite for tissue and biomedical engineering applications. This work presents fish gelatin random and aligned electrospun membranes cross-linked with glutaraldehyde (GA). It was observed that the fiber average diameter and the morphology is not influenced by the GA exposure time and presents fibers with an average diameter around 250 nm. Moreover, when the g...

Fracasso, Hélio Augusto A.; Branco, Joaquim Olinto; Efe, Márcio Amorim; Barreiros, João P.

In this work, we intend to describe the reproductive dynamics of Sterna hirundinacea in an island fromSouth Brazil.We studied the reproductive biology of this species in its natural environment and provide data on their growth, survival, and reproductive success in Ilha dosCardos, SantaCatarina, South Brazil. Samplingswere carried out daily on the island throughout the reproductive seasons of 2003, 2005, and 20...
