Polymorphisms of the TNF, LTA, and TNFRSF1B genes are associated with onsets of menarche and menopause in US women of European ancestry

open access: yesAnnals of Human Biology, 2021
Background The TNF, LTA and TNFRSF1B genes have been implicated in various traits related to menarche and menopause. Aim To analyse the TNF, LTA and TNFRSF1B genes for their association with ages at menarche (AM) and natural menopause (ANM). Subjects and

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada

open access: yesPopulation Ecology, EarlyView.
We examine historical population data for spruce budworm from several locations through the period 1930–1997, and use density‐dependent recruitment curves to test whether the pattern of population growth over time is more consistent with Royama's (1984; Ecological Monographs 54:429–462) linear R(t) model of harmonic oscillation at Green River New ...

Small terrestrial mammals living along streams acting as natural landscape barriers

open access: yesEkológia (Bratislava), 2016
Riparian stands along streams are important landscape elements – biocorridors, allowing the dispersal of many small terrestrial mammals. Streams are, however, also barriers limiting dispersal, which leads to isolation and population-genetic changes ...

Calling the Social Sciences Names

open access: yesRevue d’Histoire des Sciences Humaines, 2020
Throughout the 1950s, the use of the behavioral sciences label went together with the affirmation of social science’s collective ambitions to use quantitative methods and to practice interdisciplinary cooperation, but it also helped differentiation ...

Transdisciplinary methods in the study of biological membranes: laboratory learning by doing and implications for research and education

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2021
The investigation of the structural features in biological membranes represents a central topic in many aspects of biological science. It involves the study of the collective behavior of a great number of interacting macromolecules, while the study of ...

Complex Systems Science: Dreams of Universality, Reality of Interdisciplinarity [PDF]

open access: yes, 2012
Using a large database (~ 215 000 records) of relevant articles, we empirically study the "complex systems" field and its claims to find universal principles applying to systems in general. The study of references shared by the papers allows us to obtain

Taming the terminological tempest in invasion science

open access: yesBiological Reviews of The Cambridge Philosophical Society
Standardised terminology in science is important for clarity of interpretation and communication. In invasion science – a dynamic and rapidly evolving discipline – the proliferation of technical terminology has lacked a standardised framework for its ...

Network topology drives population temporal variability in experimental habitat networks

open access: yesPopulation Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

Geographic variation in walking activity in the red flour beetle Tribolium castaneum

open access: yesPopulation Ecology, EarlyView.
This study examined whether there is geographic variation in field populations, focusing on the moving activity in the red flour beetle Tribolium castaneum. Results showed significant differences in moving activity among field populations but no correlation with latitude or meteorological factors.
