Understanding the management logic of private forest owners: a new approach
Recently, several typologies of non-industrial private forest owners were established in order to assess their
objectives and attitudes toward forests. However, current management practices and work organization
have usually not been explicitly addressed in these empirically based typologies. In a context of increasing
outsourcing and decreasing family work in forests, it is important to know the forest practices, who carries
them out, and with whose labour and equipment. The interrelated knowledge of these variables sheds light
on the constraints faced by different forest owners and about the agents caring for their forests. Such
knowledge can also improve the understanding of forest owners' behaviour and, therefore, be useful for the
design and implementation of forest policies. The work models of Portuguese non-industrial private forest
were identified with these goals in mind. A cluster analysis, using a representative nationwide sample and an
empirically based set of variables, was instrumental in identifying six work models. The interrelation
amongst these models and other variables such as landholding attributes (e.g. forest size and dominant
species), owners' social profile, and their economic goals was also assessed. Finally, the main dynamics of
private owners' forest management are outlined
Promoting Landscape-Level Forest Management in Fire-Prone Areas: Delegate Management to a Multi-Owner Collaborative, Rent the Land, or Just Sell It?
Forest management at the landscape level is a requirement for reducing wildfire hazard. In
contexts where non-industrial private forest ownership prevails, the collaboration among multiple
owners has been proposed as the way forward to reach consistent fuel management at that level.
The current literature has been focused on identifying the factors that lead to collaboration among
owners. In this study we explored other ways to reach landscape-level management in addition to
the collaborative way, such as those that may be promoted through land renting or selling. Different
contexts and owner types may require different solutions. Thus, we explicitly asked which alternative
would be chosen by a given forest owner, from the following set: keeping individual management,
entering a multi-owner collaborative arrangement where they delegate management, renting to
a pulp company; or selling the land. In a context of small-scale ownership and high recurrence of
wildfires in Portugal, a face-to-face survey was carried out to a sample of landowners. Our results
suggest that there is not an a priori generalized unwillingness of owners to delegate management,
rent or sell the land and thus they seem prone to align themselves with policy strategies to promote
management at the landscape level. Multinomial logit regression modelling allowed us to explain and
predict owners’ choices among the aforementioned set of alternative management options. We found
that choosing multi-ownership collaboration, as opposed to keeping current individual management,
is associated with passive management under harsher conditions, by non-residents without bonding
capital. The identified factors of owners’ choices show the limited scope of tenancy and land-market
mechanisms to promote landscape-level management. The best policy option was found to depend
on the owner profiles prevailing in the target area. This suggests that studying the existing context
and owner types is required to design effective policiesinfo:eu-repo/semantics/publishedVersio
A farming systems approach to linking agricultural policies with biodiversity and ecosystem services
Concepts and QuestionsMany countries are reshaping their agricultural policies to better enhance biodiversity and ecosystem services (BES) in farmlands,
but measuring the effectiveness of policy instruments in BES delivery is challenging. Using the European Agricultural Policy as an
example, we propose the application of a farming systems (FS) approach as a cost-effective tool for linking policy design and
expected BES outcomes. On the basis of available data from subsidy payment agencies, such an approach can identify groups of
farms that share similar management practices as well as the associations between FS and corresponding BES potential, and
improve modeled outputs of farm management responses to policies and other drivers of change. We describe how this relatively
unexplored source of information can help to support applied ecological research and relevant policy, and call for these data to be
made available across Europe and elsewhereN/
A short review of the distribution of short-beaked common dolphins (Delphinus delphis) in the central and eastern North Atlantic with an abundance estimate for part of this area
This paper uses data from 3 programmes: (1) the North Atlantic Sightings Surveys (NASS) surveys undertaken throughout much of the central and eastern North Atlantic north of about 40° N in 1987, 1989, 1995 and 2001; (2) the MICA-93 programme; and (3) the north eastern Atlantic segment of the Small Cetacean Abundance in the North Sea (SCANS) survey in 1994. The data from all surveys were used to examine the distribution of common dolphins in the NE Atlantic. No sightings were made north of 57° N. An initial attempt to examine distribution against 4 potential non biological explanatory variables was made. A simple interpretation of the preliminary analyses presented here is that the primary areas for groups of common dolphins were in waters over 15° C and depths of 400-1,000 m (there does appear a link with shelf features), between around 49°-55° N especially between 20°-30°W. An illustrative example of spatial modelling is presented. Only for 1 year (and part of the total survey area) were there sufficient data to attempt to estimate abundance: 1995. The estimated abundance in the W Block of the NASS-95 Faroese survey was 273,159 (cv=0.26; 95% CI=153,392-435,104) short-beaked common dolphins. This estimate is corrected for animals missed on the trackline (g(0)) and for responsive movement.Publisher PDFPeer reviewe
Vet-OncoNet: Malignancy Analysis of Neoplasms in Dogs and Cats
Analysis of canine and feline tumor malignancy data can help clinicians identify high-risk patients and make more accurate decisions. Based on a sample of 16,272 cancer records, including 3266 cats and 13,006 dogs, collected from January 2019 to December 2021 in the Vet-OncoNet Network database, this study aimed to compare the tumor malignancy profile between cats and dogs, considering animal-related factors (sex, age, and breed), topography, and geographic location using a mixed-effects logistic regression model. Cats had a higher proportion of malignant tumors (78.7%) than dogs (46.2%), and the malignancy profile was very different regarding tumors’ topographies.The mean age of malignant tumors occurred eight months later than benign ones (9.1, SD = 3.4; 9.8,SD = 3.2), in general. Species (OR = 3.96, 95%CI 3.57: 4.39) and topography (MOR = 4.10) were the two most important determinants of malignancy risk. Female dogs had a higher risk than male
dogs (OR = 1.19, 95%CI 1.08: 1.31), which does not appear to be the case in cats (OR = 0.98, 95%CI0.77: 1.23). Breed contributed significantly to differences in malignancy risk in dogs (MOR = 1.56), particularly in pit bulls and boxers. District of residence was not so relevant in predicting malignancy risk (MOR = 1.14). In both species, the risk of malignancy increased by approximately 20% every three years. It could be hypothesized that species differences in genetic structure may contribute to tumor malignancy
Cardiac Tamponade after Thrombolysis for Acute Ischemic Stroke - A Case with an Excellent Outcome Ana Vera-Cruz
Intravenous thrombolysis with recombinant tissue plasminogen activator (rtPA) is the established treatment for acute ischemic stroke and has been highly effective in reducing the neurological deficit. Serious adverse events are not uncommon, with hemorrhage being the major complication. We describe the case of a patient with acute ischemic stroke that also presented with vague cardiac symptoms and was treated with rtPA, which was complicated by a hemopericardium causing cardiac tamponade. Pericardiocentesis was promptly performed, which resulted in rapid resolution of the cardiogenic shock. The patient recovered consciousness within a few minutes. A search of the MEDLINE database shows that this is the first report of cardiac tamponade after rtPA thrombolysis occurring in a patient with no history of recent myocardial infarction or aortic dissection
Pharmacological and Non-Pharmacological Agents versus Bovine Colostrum Supplementation for the Management of Bone Health Using an Osteoporosis-Induced Rat Model
Osteoporosis is defined by loss of bone mass and deteriorated bone microarchitecture. The present study compared the effects of available pharmacological and non-pharmacological agents for osteoporosis [alendronate (ALE) and concomitant supplementation of vitamin D (VD) and calcium (Ca)] with the effects of bovine colostrum (BC) supplementation in ovariectomized (OVX) and orchidectomized (ORX) rats. Seven-month-old rats were randomly allocated to: (1) placebo-control, (2) ALE group (7.5 μg/kg of body weight/day/5 times per week), (3) VD/Ca group (VD: 35 μg/kg of body weight/day/5 times per week; Ca: 13 mg/kg of body weight/day/3 times per week), and (4) BC supplementation (OVX: 1.5 g/day/5 times per week; ORX: 2 g/day/5 times per week). Following four months of supplementation, bone microarchitecture, strength and bone markers were evaluated. ALE group demonstrated significantly higher Ct.OV, Ct.BMC, Tb.Th, Tb.OV and Tb.BMC and significantly lower Ct.Pr, Tb.Pr, Tb.Sp, Ct.BMD and Tb.BMD, compared to placebo (p < 0.05). BC presented significantly higher Ct.Pr, Ct.BMD, Tb.Pr, Tb.Sp, and Tb.BMD and significantly lower Ct.OV, Ct.BMC, Tb.Th, Tb.OV and Tb.BMC compared to ALE in OVX rats (p < 0.05). OVX rats receiving BC experienced a significant increase in serum ALP and OC levels post-supplementation (p < 0.05). BC supplementation may induce positive effects on bone metabolism by stimulating bone formation, but appear not to be as effective as ALE
Cross Species Analysis and Comparison of Tumors in Dogs and Cats, by Age, Sex, Topography and Main Morphologies. Data from Vet-OncoNet
The animal cancer burden is essential for the translational value of companion animals in comparative oncology. The present work aims to describe, analyze, and compare frequencies and associations of tumors in dogs and cats based on the Animal Cancer Registry created by Vet-OncoNet. With 9079 registries, regarding 2019 and 2020, 81% (n = 7355) belonged to dogs. In comparison, cats have a general one-year right advance in the mean age of cancer diagnosis compared to dogs. The multivariate topography group analysis shows a distinct pattern between the two species: dogs have higher odds of cancer in the genito-urinary system, spleen, soft tissue tumors and skin, while cats show higher odds for tumors in the eyes, digestive organs, nasal cavity, lymph nodes, bones and mammary glands. Regarding morphologies, dogs are overrepresented in mast cell tumors (MCT), melanomas, and hemangiosarcomas. While cats are overrepresented in fibrosarcomas, lymphomas (T and B-cell), in malignant mammary tumors, and squamous cell carcinoma (SCC). Females have greater odds only in the mammary gland, with males having greater odds in six of twelve topographies. This study is the first outcome of continuous animal cancer registration studies in Portugal
Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial
Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials.
Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure.
Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.
