Intra and in terspecific competiti on for n ectar play an imports nt role in hummingbird communities. Larger sized species usually exclude smaller species from the rich floral resources. However, it has been recently postulated that the competitive advantages of a large body size decline as the evolutionary distance between the contending species in creases. In this study, we analyzed dominance hierarchy dynamics in a hummingbird assemblage in central Mexico. By monitoring hummingbird territories established in three plant species through 1 year, we assessed the effects of energy within territories and the territory owners identity in the frequency of inter and intraspecific encounters. We also evaluated if these factors affect the dominance of larger species when they compete against smaller distantly related contenders. Our results show that their frequency of intraspecific encounters was related with the identity of the territory's owner. On the contrary, the frequency of interspecific encounters was related with both the territory and the identity of the territory's owner. We did not find a significant difference between the number of encounters dominated by larger and smaller species and their conte nders. However, the in crease in genetic dista nee between contenders was positively associated with a higher frequency of encounters dominated by small *** results showed that the ecological factors and evolutionary relationships among contenders play important roles in the dominance hierarchy dynamics.

Background: Intussusception is defined as a telescoping of a proximal gastrointestinal segment with its mesentery to a distal one, only 5% occur in adults and in colon the probability that it is caused by a malignant disease is up to 65%. Only 1% occurs in a retrograde manner, the rest occur in an anterograde manner. Aim: Describe the clinical presentation of an intussusception in the adult patient as well as its most frequent causes and possible complications that influence decision making for a definitive treatment. Case Presentation: A 66-year-old woman diagnosed with colon adenocarcinoma who underwent elective transverse colectomy and colonic anastomosis with an incidental finding of a transverse colon tumor in a retrograde intussusception was studied. Conclusion: In any adult patient with an intussusception especially in colon a neoplasia should be suspected and the affected segment should be resected without being reduced due to the risk of perforation and tumor dissemination.

Strong evidence supports the benefits of regular physical activity/exercise for the prevention and management of numerous non-communicable diseases.^(1,2)However,despite important advances(particularly the implementation of complex“omics”approaches),the underlying molecular mechanisms remain to be clearly *** the past decade,the role of exerkines—a myriad of signaling moieties(e.g.,mainly cytokines but also other small peptides,peptides,nucleic acids,lipids,or metabolites,among others)released by muscles(myokines)and other tissues in response to exercise that induces endocrine(at the multisystem level),paracrine,or autocrine effects—has gained attention.^(3,4)Indeed it has been proposed that some of the salutary effects of regular exercise(i.e.,repeated sessions of acute exercise)might be due,at least partly,to the progressive accumulation of frequent,acute episodes of exerkine release.^(5)

Notwithstanding the emergence of FinTech startups in the financial services industry,most of these companies face significant difficulties in breaking even and *** study examines the main managerial, institutional, and financial drivers of FinTechprofitability and the time it takes for these firms to break even. The database includesrelevant qualitative factors, such as foundational characteristics, the technologicalprofile of the startup, and its funding structure. Using the full population of FinTechstartups operating in Spain from 2005 to 2017, we observe that most of these firms areunprofitable within three years of their inception. Combining panel data and survivalanalyses, we empirically find that large and solvent FinTech firms founded by singleentrepreneurs in an incubator or accelerator program are more likely to be profitableand prevail. FinTech firms reach their break-even points faster if they receive fundingthrough seed capital.
