Title: Enhancing biodiversity and ecosystem services in quarry restoration – challenges, strategies, and practic
Authors: Salgueiro, Pedro; Prach, Karel; Branquinho, Cristina; Mira, António
Abstract: Although covering less than 1% of the land surface, extraction activities have long-lasting impacts on local ecosystems, inevitably damaging biological diversity and depleting ecosystem services. Many extractive companies are now aware of their impacts and, while pressured by society, demand concrete solutions from researchers to reverse the effects of exploitation
and restore biodiversity and ecosystem services. In this article, we compile and synthesize the contributions of the latest available research on quarry restoration. We depict and discuss some of the most pressing issues regarding (1) the challenges of restoring quarries; (2) the opportunities for biodiversity and ecosystem services delivery; and (3) outline further research addressing current gaps. We conclude that quarries pose different abiotic and biotic constraints that act interdependently, hampering the attainment of effective restoration if considered solely. Such constraints need to be addressed holistically to
lastly encourage the self-sustainability of the system by reinstating ecological processes. However, a restored site does not have to specifically mimic the pristine situation, as under certain conditions alternative approaches may uphold valuable natural assets contributing to the conservation of rare, restricted, or protected species and habitats.2020-01-01T00:00:00ZEstimating the population and distribution trends of owls in Portugal using citizen science data from Program NOCTUAPortugal and other sources

Abstract: During the last eight years (2010-2017), the Working Group on Nocturnal Birds of SPEA
(GTAN-SPEA) has carried out a volunteer monitoring program (NOCTUA-Portugal) to determine the population trends of seven owl species at a national scale. We used generalized estimating equations models to assess trends. In addition, we used the distribution data from breeding bird atlases, observations sent by collaborators, and data from the public online database PortugalAves/eBird to detect changes in distribution in a four-decade period (1978-2017). We defined four periods to study potential changes in distribution of owls in Portugal: 1978-1984 (1st breeding bird atlas); 1999-2005 (2nd breeding bird atlas); 2006-2014 (interval between 2nd and 3rd breeding bird atlases); and 2015-2017 (ongoing 3rd breeding bird atlas). Three species had negative population and distribution trends: Common Barn-owl (Tyto alba), Eurasian Scopsowl (Otus scops), and Little Owl (Athene noctua). The Eurasian Eagle-owl (Bubo bubo) had a slightly positive population and distribution trends, while the Tawny Owl (Strix aluco) was stable or slightly declined. The population trend of the Northern Long-eared Owl (Asio otus) was
unknown because of large fluctuations, and due to the low number of records it was not possible to determine a population trend for the Short-eared Owl (Asio flammeus).2021-01-01T00:00:00ZEstimating the population and distribution trends of owls in Portugal using citizen science data from Program NOCTUAPortugal and other sources

Title: Syphilis in Coimbra at the beginning of the 20th century: the importance of hospital records for the study of the disease
Authors: Lopes, Célia
Abstract: Syphilis is a chronic sexually or congenitally transmitted infection, with a well-documented clinical past, having been one of the major public health problems in Europe. In Portugal, there is a lack of data regarding the number of individuals infected by syphilis, or even about the characteristics of the disease and the infected people, in past official statistics. Hence, the main purpose of this study was to appraisal some of these omissions in order to extend our knowledge of this infection in the past. The aim was to obtain data about the disease in the first years of the 20th century, as well as the demographic and the socioeconomic profile of the affected individuals. The intention was also to characterize the disease, identifying the most frequent lesions and their locations in the human body. Among the patients who were hospitalized in the Hospitals of the University of Coimbra (HUC) between 1904 and 1937, 5.9% were diagnosed with syphilis. Most of them (89.3%) with the acquired form of the disease, which affected mainly single young adults (20–39 years) independently of their sex. Congenital syphilis was detected mainly in children (0–4 years). Most hospitalizations for congenital syphilis (53.9%) occurred when the disease was in its tertiary form, which did not happen in the acquired form of the disease (29.5%). The most frequent forms of tertiary syphilis were malignant, affecting 33.4% of patients with the disease at its most advanced stage.2019-01-01T00:00:00Z
