Species size affects hatching response to different temperature regimes in a rotifer cryptic species complex
2013
The strategy of decreasing size with increasing temperature known as Bergmann’s rule operates at geographic scale and in spite of extensive studies still presents a puzzle to researches. The aim of this work was to verify whether patterns of diapausing egg hatching of closely related species are consistent with the expectations from Bergmann’s rule. In a laboratory study of the cryptic species complex of the rotifer Brachionus plicatilis, the response to temperature (17.5, 22.5, and 25.0 °C) of diapausing eggs collected in a pond where the three tested species coexist was assessed by (1) the number of hatchlings emerging or (2) the time needed to hatch. Our results show that the response to…
Racial disparity and prognosis in patients with mouth and oropharynx cancer in Brazil.
2022
Oral and oropharyngeal cancer (OPC) is an important cause of morbidity and mortality worldwide. Populations in situations of social vulnerability tend to have higher incidences of cancer, a higher proportion of late diagnosis, greater difficulties in accessing health services, and, consequently, worse prognosis. The aim of this study was to evaluate the relationship between race/skin color and OPC prognosis in Brazil. This is a cross-sectional epidemiological study using OPC data from the National Cancer Institute between the years 2000 and 2019. The selected variables were: gender, race/skin color, age, education, smoking and alcohol consumption, stage of the disease and disease status at …
Peaceful Foreign Policy and Remembrance of War Effort : The Conceptualisation of Willingness to Defend in Finland and Its Connections to Previous Arm…
2022
In Finland, a conceptualization of willingness to defend has been a traditional part of the defence-related debates and the state has vested interests to maintain the high level of willingness. This paper examines the connections to the Second World War in political discourse related to willingness to defend. Based on the analysis of political and societal debates, I will demonstrate that the Second World War serves as an historical experience for the understanding of the concept by offering an idea of individual sacrifice relevant to the survival of the state, as a prime example. peerReviewed
Nietoperze Chiroptera: estywacja, hibernacja, torpor
2021
Wahania temperatury otoczenia i obniżona wilgotność powodują u wielu zwierząt, w t u nietoperzy, stres fizjologiczny. Jego następstwem jest spadęk temperatury ciała, czyli hipotermia adaptacyjna. c aktywacja mechanizmu odrętwienia. Stany odrętwienia mogą być wywoływane przez różne czynniki: najcz ęście . to zmiany temperatury, brak pożywienia, światła i fotoperiodyzm, poziom tlenu lub dwutlenku węgla w organizn Minimalizacji ulega także wrażliwość osobnika na bodźce zewnętrzne. Stan odrętwienia u nietoperzy może podzielić na podkategońe. Wyróżniamy takie stany aktywności sezonowych zwierząt, jak: hibernacja, estywa torpor. Zjawisko heterotermii dotyczy wszystkich gatunków nietoperzy, które …

Expression of IAPs (Inhibitory of Apoptosis Proteins) and of their alternative splice variants in hepatocellular carcinoma tissues and cells
2004
IAPs (inhibitors of apoptosis proteins) might have a major role in the apoptotic resistance that marks many cancers. The studies on IAPs in human HCC have focused on survivin or XIAP, indicating that their new or increased expression in this tumor is associated with a more unfavorable prognosis. The present results corroborate these findings, emphasizing the role that the coordinated expression of different IAPs and alternative splice variants might play in the adverse biology of hepatocellular carcinoma.
Respostas e adaptações de comunidades de colêmbolos (Hexapoda: Collembola) a condições de inundação e hipoxia
2009
Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses to different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity. Sites more affected by flooding are dominated by hygrophilic and hygrotolerant species, whereas the hardwood floodplain is dominated by mesophilic species. The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of sever…
Análisis demográfico de bancos de huevos diapáusicos de rotíferos
2006
Los huevos diapáusicos de rotíferos se han reconocido como una etapa fundamental del ciclo vital de los rotíferos que habitan ambientes temporalmente variables ya que permiten la supervivencia de las poblaciones durante los periodos de condiciones adversas. No obstante, el estudio de los bancos de huevos diapáusicos de rotíferos en ambientes naturales ha recibido mucha menos atención que el estudio de sus poblaciones activas. La mayor parte de la información sobre etapas de resistencia en el zooplancton proviene de otros grupos (cladóceros y copépodos). El objetivo de esta tesis consiste en caracterizar demográficamente los bancos de huevos diapáusicos del complejo de especies del rotífero …
Measuring the potential for growth in populations investing in diapause
2014
AbstractThe intrinsic rate of population increase (r) is a common performance measure in many ecological and evolutionary studies. However, in life cycles with diapause investment resources are split into a short-term (current population growth) and a long-term (population survival through periods of unsuitable habitat conditions) component, which complicates the use of r as a single performance measure. Here we propose a new measure that integrates both performance components into a single parameter, the potential intrinsic growth rate, rpot. This is the rate of increase that a population/genotype would have if no investment in diapausing stages would occur. We show that rpot can be comput…
