The role of fish life histories in allometrically scaled food‐web dynamics
2019
Body size determines key ecological and evolutionary processes of organisms. Therefore, organisms undergo extensive shifts in resources, competitors, and predators as they grow in body size. While empirical and theoretical evidence show that these size‐dependent ontogenetic shifts vastly influence the structure and dynamics of populations, theory on how those ontogenetic shifts affect the structure and dynamics of ecological networks is still virtually absent. Here, we expand the Allometric Trophic Network (ATN) theory in the context of aquatic food webs to incorporate size‐structure in the population dynamics of fish species. We do this by modifying a food web generating algorithm, the nic…
Do plant-based biogeographical regions shape aphyllophoroid fungal communities in Europe?
2018
Aim: Aphyllophoroid fungi are associated with plants, either using plants as a resource (as parasites or decomposers) or as symbionts (as mycorrhizal partners). In spite of their strong association with plants, it is unknown how much plant distributions determine their biogeographical patterns compared with environmental factors such as climate and human land use. In this study, our aims are to (1) describe the spatial diversity patterns of aphyllophoroid fungi in Europe and (2) identify the factors shaping these patterns. Location: Europe, as well as the adjacent Subarctic to Arctic islands (Greenland, Faroe Islands, Iceland, Svalbard), Palestine and the south-east coast of the Caspian Sea…

Femininity and Fertility in Sisters with Twin Brothers: Prenatal Androgenization? Cross-Sex Socialization?
2002
Are sisters of twin brothers behaviorally or physiologically masculinized? Prenatal exposure to their brothers' androgens and postnatal socialization experiences unique to girls growing up with twin brothers might influence their attitudes, pubertal development, and reproductive histories. To investigate, we studied age- and cohort-matched samples of Finnish sisters from same-sex and opposite-sex twin pairs. Using data from two ongoing longitudinal studies of consecutive birth cohorts of Finnish twins, we assessed pubertal development at ages 11 and 14 and endorsement of attitudes associated with femininity at age 16. We also studied fertility in Finnish women from same- and opposite-sex t…
Approssimazioni alla “leggenda del legno della Croce” nell'Occitania medievale
2019
La leggenda del legno della croce è una delle storie apocrife più significative del medioevo religioso. Essa è il risultato di un lungo processo di stratificazione di racconti e motivi leggendari, e risulta declinata in versioni plurime, più o meno scorciate e interpolate. Il presente contributo indaga la diffusione della storia del lignum crucis nel contesto occitano. La scelta non è casuale; appare, anzi, necessaria. In effetti, come spesso è avvenuto per quella che può essere considerata un’appendice alla cosiddetta «eccezione narrativa» occitana, lo studio della letteratura religiosa del Midi necessita ancora di nuovi spunti d’indagine, trasversali e comparativi. Di questo soffrono anch…
La investigación universitaria en periodismo científico
2003
En este artículo, la autora revisa y examina las aportaciones bibliográficas sobre comunicación científica que se han realizado desde distintas áreas de conocimiento, en las últimas décadas en nuestro país. Así pues, muestra las debilidades presentes en los escasos estudios sobre el tratamiento informativo de la ciencia y la tecnología, realizados desde las facultades de Ciencias de la Información y la fortaleza de los trabajos abordados desde las facultades de Ciencias Experimentales donde hay abierta una línea de investigación sobre historia del periodismo científico. In this article, the author revises and she examines the bibliographical contributions about scientific communication that…
Politics of Identity Exploring the relevance and salience of identity as a political concept within contemporary American politics
2020
Master´s thesis in English (EN501). This thesis examines how politics became identity and how politicized identities are shaping contemporary American politics. Identity as a political concept in the Western sphere evolved by virtue of our human thymotic desire to be recognized and dignified by other people. Identity as a political phenomenon rests on the belief of individuals and their surrounding society that there exists a true inner self in all of us that is both entitled to and worthy of recognition and dignity. The struggle to have that true inner self recognized was inaugurated by Martin Luther’s reconnaissance of the inner chambers of the self and moved to the social and political s…
Innovative Analysis of Service-Learning Effects in Physical Education: A Mixed-Methods Approach
2020
Purpose: To compare the development of teaching competency in preservice teachers of physical education (n = 96) through two different modalities of intervention from the same service-learning program. The preservice teachers provided a direct service to children with motor functional diversity, promoting their motor skills and counteracting their lack of social attention. Method: The topic was approached using mixed methods with methodological triangulation. Quantitative evidence was gathered through a quasi-experimental design of two nonequivalent experimental groups implementing the following instrument: the Teaching Competency while performing Motor Skills and Body Language Games Rubric…
Bruk av dyr i vitenskapelige eksperimenter : en filosofisk undersøkelse
2004
I dette arbeidet behandles filosofiske og etiske spørsmål som oppstår i forbindelse med bruk av dyr i vitenskapelige eksperimenter. Med vitenskapelige eksperimenter menes eksperimenter innenfor all slags medisinsk og veterinærmessig forskning og innenfor arbeid som tar sikte på å utvikle og prøve medikamenter. Det tenkes altså både på anvendt forskning og på grunnforskning. Forfatteren kommer ikke inn på bruk av dyr i kosmetikkindustrien, i matvareproduksjonen eller i kontrollen av matvarer. Det gås heller ikke inn på bruk av dyr som kjæledyr eller som følgedyr.
Parental effects on offspring longevity--evidence from 17th to 19th century reproductive histories.
2004
Family studies provide support for a modest genetic influence on offspring life span, although the magnitude of these correlations is small.The study aimed to clarify the relative contributions of parental age at birth and overall parental longevity on offspring lifespan, and to identify the biological and cultural mechanisms.Information was derived from two village genealogies (1650-1927) encompassing 9979 births (5315 males, 4664 females). Data selection was guided by the inclusion of information about parental age at birth and lifespan, offspring lifespan and cohort-specific life expectancy.Parental age at reproduction displayed a negative association with offspring survivability, which …
