The interpretation of patterns of biodiversity requires the disentanglement of geographical and environmental variables. Disjunct alpine communities are geographically isolated from one another but experience similar environmental impacts. Isolated homogenous habitats may promote speciation but constrain functional trait variation. In this study, we examined the hypothesis that dispersal limitation promotes taxonomic divergence, whereas habitat similarity in alpine mountains leads to functional convergence. We performed standardized field investigation to sample non-volant small mammals from 18 prominent alpine sites in the Three Parallel Rivers area. DNA Damage inhibitor We estimated indices quantifying taxonomic and functional alpha- and beta-diversity, as well as beta-diversity components. We then assessed the respective importance of geographical and environmental predictors in explaining taxonomic and functional compositions. No evidence was found to show that species were more functionally similar than expected in local assemblages. However, the taxonomic turnover components were higher than functional ones (0.471±0.230 vs. 0.243±0.215), with nestedness components showing the opposite pattern (0.063±0.054 vs. 0.269±0.225). This indicated that differences in taxonomic compositions between sites occurred from replacement of functionally similar species. Geographical barriers were the key factor influencing both taxonomic total dissimilarity and turnover components, whereas functional beta-diversity was primarily explained by climatic factors such as minimum temperature of the coldest month. Our findings provide empirical evidence that taxonomic and functional diversity patterns can be independently driven by different ecological processes. Our results point to the importance of clarifying different components of beta-diversity to understand the underlying mechanisms of community assembly. These results also shed light on the assembly rules and ecological processes of terrestrial mammal communities in extreme environments.Recent studies have shown that the closely related cinereous tit ( Parus cinereus) and green-backed tit ( P. monticolus) in China display strong egg recognition ability in contrast to tit species in Europe, which lack such ability. However, egg recognition in other populations of cinereous and green-backed tits and additional Paridae species still requires further research. Here, we compared the egg recognition abilities of cinereous tits across China, green-backed tits ( P. m. insperatus) in Taiwan, China, and five other species from the Paridae family, including the marsh tit ( Poecile palustris), varied tit ( Sittiparus varius), willow tit ( Poecile montanus), coal tit ( Periparus ater), and ground tit ( Pseudopodoces humilis). Results showed that the Hebei (58.8% egg rejection, n=17) and Liaoning populations (53.3%, n=15) of cinereous tits, and the Guizhou (100%, n=12) and Taiwan populations (75%, n=12) of green-backed tits all exhibited high egg recognition ability. The egg recognition ability of these tits was significantly greater than that of the other five species in the Paridae family. The varied tit (5.4%, n=37), marsh tit (8.3%, n=12), willow tit (Hebei 25%, n=20; Beijing 9.5%, n=21), coal tit (16.7%, n=18), and ground tit (0, n=5) species all showed low egg recognition abilities, with no significant differences found among them. Egg recognition was not associated with a single phylogenetic group but occurred in several groups of tits. In particular, those species widely distributed in the Indomalayan realm, thus overlapping with small cuckoo species, displayed strong egg recognition ability, whereas tit species in the Palearctic realm exhibited low or no egg recognition ability.
Major bleeding events in heart failure (HF) patients are poorly described. We sought to investigate the importance of major bleeding and its impact on outcomes in HF patients.

We analysed incident bleeding and ischaemic events during a 3year follow-up in 2910 HF outpatients included in a prospective multicentre registry. Major bleeding was defined as a Type ≥3 bleed using the Bleeding Academic Research Consortium definition. Ischaemic event was a composite of ischaemic stroke and myocardial infarction. Events were adjudicated by a blinded committee. At inclusion, most patients (89%) received at least one antithrombotic anticoagulation (53.9%) and/or antiplatelet therapy (46.2%). Bleeding occurred in 111 patients 3year cumulative incidence 3.6% [95% confidence interval (CI) 3.0-4.3] and ischaemic events in 102 patients [3year cumulative incidence 3.3% (95% CI 2.7-4.0)]. Most bleedings were Bleeding Academic Research Consortium 3a (32.5%) or 3b (31.5%). Most frequent sites of bleeding were gastrointestina annually (as frequent as ischaemic events) and is associated with a dramatic increase in mortality (at least as severe as ischaemic events). Most events occurred in patients receiving anticoagulation. Knowledge of these findings may help physicians to manage antithrombotics in HF patients.
This study aimed to examine whether pregnancy following bariatric surgery affects long-term maternal weight change and offspring birth weight.

Using data from the Longitudinal Assessment of Bariatric Surgery (LABS)-2 study, linear regression was used to evaluate percent change in total body weight over a 5-year follow-up period among reproductive-aged women who underwent Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding as well as evaluate the association of bariatric procedure type and offspring birth weight.

Of 727 women with preoperative age of 36.1 (6.3) years (mean [SD]) and BMI of 46.9 (7.0) kg/m
, 80 (11%) reported at least one pregnancy. After adjusting for covariates, percent change in total body weight was not significantly different between women who became pregnant and those who did not during a 5-year follow-up period (β = 2.02; 95% CI -1.03 to 5.07; P = 0.19). Additionally, mean birth weight was not significantly different between mothers who underwent Roux-en-Y gastric bypass versus laparoscopic adjustable gastric banding (P = 0.99).

Postoperative pregnancy did not diminish long-term weight loss in women in the LABS-2 study. The finding of comparable weight loss is relevant for providers counseling women of reproductive age on weight-loss expectations and family planning following bariatric surgery.
