Red deer as a disperser of native,but not invasive plants’seeds

Integrative Zoology 2023年第5期18卷 859-866页

作者： Fernanda GARCIA António alves DA SILVA Ruben HELENO JoséPaulo SOUSA joana alves Centre for Functional Ecology(CFE) TERRA Associate LaboratoryDepartment of Life SciencesUniversity of CoimbraCoimbraPortugal

INTRODUCTION Seed dispersal is a key process in the life cycle of most plants,with ecological and evolutionary consequences that go beyond vegetation dynamics and cascade to entire ecosystem functioning and stability(Traveset et al.2014).Seed dispersal largely constrains plant recruitment and the distribution of future plant cohorts,thus playing a critical role in the restoration of disturbed sites(Cain et al.2000;Higgins et al.2003).It can also threaten plant diversity by facilitating plant invasions(Vavra et al.2007;Heleno 2020).

Developing and validating a nestling photographic aging guide for cavity-nesting birds: an example with the European Bee-eater(Merops apiaster)

Avian Research 2020年第1期11卷 57-64页

Background: Accurate estimation of nestlings’ age is essential in avian demography studies as well as in population ecology and conservation. For example, it can be useful for synchronizing nest visits with events of particular interest, such as the age at which young can be safely ringed, or in choosing the best period to attain the most accurate calculation of laying or hatching ***: We constructed a photographic guide for aging European Bee-eaters(Merops apiaster) nestlings to 3-day age classes and evaluated the aging method by performing a validation exercise with several observers with no previous experience in aging bee-eater ***: The aging guide for bee-eater nestlings allowed estimating age to within 3 days with an average accuracy of 0.85. We found the optimal period for aging nestlings was between days 13-18(with accuracy between 0.94 and 0.99), during which the status of feather development was more easily distinguishable from the preceding and subsequent age classes. During the first 3 days after hatching, nestlings could also be aged with high accuracy(0.93). The small size of the nestling in relation to the eggs and the nestling’s inability to raise its head during these first days allowed for good discrimination from the subsequent age class. Between days 25 and 28, nestlings were correctly aged in only half of assignments(0.55 sensitivity) and nestlings belonging to class 7(days 7-9) were the least correctly identified(0.38 sensitivity). However, by visiting the nests at 12 days intervals it is possible to achieve the highest accuracy in age estimation with the smallest disturbance and logistic ***: This study highlighted how indirect methods and a simple protocol can be established and employed to quickly estimate nestling age in cases where handling nestlings is challenging or impossible, while minimizing disturbance in and around the nest.

Upper gastrointestinal bleeding risk scores： Who, when andwhy？

World Journal of Gastrointestinal Pathophysiology 2016年第1期7卷 86-96页

Upper gastrointestinal bleeding(UGIB) remains a significant cause of hospital admission. In order to stratify patients according to the risk of the compli-cations, such as rebleeding or death, and to predict the need of clinical intervention, several risk scores have been proposed and their use consistently recommended by international guidelines. The use of risk scoring systems in early assessment of patients suffering from UGIB may be useful to distinguish high-risks patients, who may need clinical intervention and hospitalization, from low risk patients with a lower chance of developing complications, in which management as outpatients can be considered. Although several scores have been published and validated for predicting different outcomes, the most frequently cited ones are the Rockall score and the Glasgow Blatchford score(GBS). While Rockall score, which incorporates clinical and endoscopic variables, has been validated to predict mortality, the GBS, which is based on clinical and laboratorial parameters, has been studied to predict the need of clinical intervention. Despite the advantages previously reported, their use in clinical decisions is still limited. This review describes the different risk scores used in the UGIB setting, highlights the most important research, explains why and when their use may be helpful, reflects on the problems that remain unresolved and guides future research with practical impact.

Cervical cancer is the second most common cancer in women living in developing countries that account high HPV incidence and mortality rates. Vaccinating girls between 9 and 14 years old is supposed to be the most cost-effective public health approach against cervical cancer. This systematic review aims to assess the application and coverage of the HPV vaccine in developing countries and identify the main challenges for the introduction of the vaccine in these settings. Eligible studies were selected according to the defined inclusion and exclusion criteria. To determine the quality of the studies was employed the STROBE checklist. This review included seven studies, encompassing the analysis of 19 countries and 112,116 girls aged from 9 to 18 years old. The coverage of HPV vaccination ranged from 13.8% to 107.4%, with most of the programs having more than 60% of coverage, which reflects a high percentage of vaccinated girls. The main challenges were lack of knowledge and worries about the vaccine, insufficient financial resources and staff workers, lack of community involvement and dissemination of important information about HPV. In developing countries that implemented the HPV vaccine, high coverage rates were achieved, despite sociocultural, economic and political challenges. In the future, studies that analyze the coverage rates after the elimination of the barriers and the repercussions on the mortality rates should be conducted, so that more developing countries have the opportunity to efficiently implement the vaccine.

The new properties of engineered nanoparti- cles drive the need for new knowledge on the safety, fate, behavior and biologic effects of these particles on organisms and ecosystems. Titanium dioxide nanoparticles have been used extensively for a wide range of applica- tions, e.g, self-cleaning surface coatings, solar cells, water treatment agents, topical sunscreens. Within this scenario increased environmental exposure can be expected but data on the ecotoxicological evaluation ofnanoparticles are still scarce. The main purpose of this work was the evaluation of effects of TiO2 nanoparticles in several organisms, covering different trophic levels, using a battery of aquatic assays. Using fish as a vertebrate model organism tissue histological and ultrastructural observations and the stress enzyme activity were also studied. TiO2 nanoparticles （Aeroxide~ P25）, two phase composition ofanatase （65%） and rutile （35%） with an average particle size value of 27.64-11 nm were used. Results on the ECs0 for the tested aquatic organisms showed toxicity for the bacteria, the algae and the crustacean, being the algae the most sensitive tested organism. The aquatic plant Lemna minor showed no effect on growth. The fish Carassius auratus showed no effect on a 21 day survival test, though at a biochemical level the cytosolic Glutathione-S-Transferase total activity, in intestines, showed a general significant decrease （p〈0.05） after 14 days of exposure for all tested concentrations. The presence of TiO2 nanoparticles aggregates were observed in the intestine lumen but their internalization by intestine cells could not be confirmed.
