The Portuguese National Ecological Network - A Mapping Proposal
In Portugal, the Ecological Network (EN) was included in the Portuguese legal system in 1999 according to which it must be considered, delineated and implemented in all landscape plans at all spatial scales. Despite of all EU policies, in Portugal the EN is defined by the set of areas, values and key systems for environmental protection (article 14th of the Decree Law n. º 46/2009). Furthermore, at national level there is only the Program for National Planning Policy, which doesn’t include any EN delimitation.
This paper presents a methodology for the delineation of the National Ecological Network (NEN) based on: a) the physical sub-system which refers to physical components and their interactions; b) biological sub-system composed by habitats and flora; c) the network concept which is based on the vertical and horizontal connection of structures and information within the ecological system (Jongman, 1995; Magalhães, 2001). Moreover, the main notion of EN is to link ecosystems into a spatially coherent system through which materials and organisms flow (Opdam et al., 2006), as reflected in the Landscape-System methodology (Magalhães et al., 2007).
The Portuguese ecological networks, at different scales, has been developed according with the theoretical research and actual field of studies carried out by the Landscape Architecture Research Centre (CEAP/ISA/TUL) since the beginning of the 90s, and is closely related to the ecological landscape planning methods and policies adopted in European countries. The CEAP/ISA/TUL is developing a research project, funded by the Foundation for Science and Technology’s, aiming the proposal of a methodology for mapping and policies implementation for the NEN (Project reference: FCT-PTDC/AUR-URB/102578/2008).
The main goal of this paper is to present the NEN methodology as a component of the Landscape-System methodology (Magalhães et al., 2007) whose objectives are the maintenance, restoration or enhancement of nature conservation and biodiversity within a coherent system, safeguarding ecological and cultural values, complemented with potential multiple uses and respective evolution tendencies.
This study will focus on the NEN and will compare it with the regional and local case studies at scales 1/100.000 and 1/25.000 respectively
FIRELAN - An ecologically based planning model towards a fire resilient and sustainable landscape. A case study in Center Region of Portugal
This paper explores the role of landscape planning as a tool for rural fire prevention.
It presents a methodology for a fire resilient and sustainable landscape model (FIRELAN) that
articulates the ecological and cultural components in a suitable and multifunction land-use plan.
FIRELAN is a conceptual and ecologically based model that recognizes river basin’ land morphology,
microclimate and species combustibility as the fundamental factors that determine fire behavior and
landscape resilience, along with the ecological network (EN) for achieving ecological sustainability
of the landscape. The model is constituted by the FIRELAN Network and the Complementary Areas.
This network ensures the effectiveness of discontinuities in the landscape with less combustible landuses.
It also functions as a fire-retardant technique and protection of wildland-urban interface (WUI).
This model is applied to municipalities from Portugal’s center region, a simplified landscape severely
damaged by recurrent rural fires. The results show that land-use and tree species composition should
change drastically, whereas about 72% of the case study needs transformation actions. This requires
a significant increase of native or archaeophytes species, agricultural areas, landscape discontinuities
and the restoration of biodiversity in Natura 2000 areas. The EN components are 79% of the FIRELAN
N area, whose implementation ensures soil and water conservation, biodiversity and habitats. This
paper contributes to the discussion of the Portuguese rural fires planning frameworkinfo:eu-repo/semantics/publishedVersio

Genomic Surveillance of Yellow Fever Virus Epizootic in São Paulo, Brazil, 2016 – 2018
São Paulo, a densely inhabited state in southeast Brazil that contains the fourth most populated city in the world, recently experienced its largest yellow fever virus (YFV) outbreak in decades. YFV does not normally circulate extensively in São Paulo, so most people were unvaccinated when the outbreak began. Surveillance in non-human primates (NHPs) is important for determining the magnitude and geographic extent of an epizootic, thereby helping to evaluate the risk of YFV spillover to humans. Data from infected NHPs can give more accurate insights into YFV spread than when using data from human cases alone. To contextualise human cases, identify epizootic foci and uncover the rate and direction of YFV spread in São Paulo, we generated and analysed virus genomic data and epizootic case data from NHPs in São Paulo. We report the occurrence of three spatiotemporally distinct phases of the outbreak in São Paulo prior to February 2018. We generated 51 new virus genomes from YFV positive cases identified in 23 different municipalities in São Paulo, mostly sampled from NHPs between October 2016 and January 2018. Although we observe substantial heterogeneity in lineage dispersal velocities between phylogenetic branches, continuous phylogeographic analyses of generated YFV genomes suggest that YFV lineages spread in São Paulo at a mean rate of approximately 1km per day during all phases of the outbreak. Viral lineages from the first epizootic phase in northern São Paulo subsequently dispersed towards the south of the state to cause the second and third epizootic phases there. This alters our understanding of how YFV was introduced into the densely populated south of São Paulo state. Our results shed light on the sylvatic transmission of YFV in highly fragmented forested regions in São Paulo state and highlight the importance of continued surveillance of zoonotic pathogens in sentinel species
The global, regional, and national burden of adult lip, oral, and pharyngeal cancer in 204 countries and territories:A systematic analysis for the Global Burden of Disease Study 2019
Importance Lip, oral, and pharyngeal cancers are important contributors to cancer burden worldwide, and a comprehensive evaluation of their burden globally, regionally, and nationally is crucial for effective policy planning.Objective To analyze the total and risk-attributable burden of lip and oral cavity cancer (LOC) and other pharyngeal cancer (OPC) for 204 countries and territories and by Socio-demographic Index (SDI) using 2019 Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study estimates.Evidence Review The incidence, mortality, and disability-adjusted life years (DALYs) due to LOC and OPC from 1990 to 2019 were estimated using GBD 2019 methods. The GBD 2019 comparative risk assessment framework was used to estimate the proportion of deaths and DALYs for LOC and OPC attributable to smoking, tobacco, and alcohol consumption in 2019.Findings In 2019, 370 000 (95% uncertainty interval [UI], 338 000-401 000) cases and 199 000 (95% UI, 181 000-217 000) deaths for LOC and 167 000 (95% UI, 153 000-180 000) cases and 114 000 (95% UI, 103 000-126 000) deaths for OPC were estimated to occur globally, contributing 5.5 million (95% UI, 5.0-6.0 million) and 3.2 million (95% UI, 2.9-3.6 million) DALYs, respectively. From 1990 to 2019, low-middle and low SDI regions consistently showed the highest age-standardized mortality rates due to LOC and OPC, while the high SDI strata exhibited age-standardized incidence rates decreasing for LOC and increasing for OPC. Globally in 2019, smoking had the greatest contribution to risk-attributable OPC deaths for both sexes (55.8% [95% UI, 49.2%-62.0%] of all OPC deaths in male individuals and 17.4% [95% UI, 13.8%-21.2%] of all OPC deaths in female individuals). Smoking and alcohol both contributed to substantial LOC deaths globally among male individuals (42.3% [95% UI, 35.2%-48.6%] and 40.2% [95% UI, 33.3%-46.8%] of all risk-attributable cancer deaths, respectively), while chewing tobacco contributed to the greatest attributable LOC deaths among female individuals (27.6% [95% UI, 21.5%-33.8%]), driven by high risk-attributable burden in South and Southeast Asia.Conclusions and Relevance In this systematic analysis, disparities in LOC and OPC burden existed across the SDI spectrum, and a considerable percentage of burden was attributable to tobacco and alcohol use. These estimates can contribute to an understanding of the distribution and disparities in LOC and OPC burden globally and support cancer control planning efforts

Pervasive gaps in Amazonian ecological research
Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4
While the increasing availability of global databases on ecological communities has advanced our knowledge
of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In
the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of
Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus
crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced
environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian
Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by
2050. This means that unless we take immediate action, we will not be able to establish their current status,
much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
