Factor Analysis by R Programming to Assess Variability Among Environmental Determinants of the Mariana Trench [PDF]
Turkish Journal of Maritime and Marine Sciences Volume: 4 Issue: 2
(2018) 146-155, 2018 The aim of this work is to identify main impact factors affecting variations in the geomorphology of the Mariana Trench which is the deepest place of the Earth, located in the west Pacific Ocean: steepness angle and structure of the sediment compression.

Population Ecology, EarlyView.This study examines the demographic dynamics of two seabird populations on Tromelin Island, 15 years after the eradication of brown rats. The results indicate that these populations are in good health and are expected to continue growing until breeding sites are saturated in about a century.

Correlation of Environmental Factors and Diatom Assemblages in Akkeshi-ko Estuary System [PDF]
, 2011 The correlation between diatoms and environmental factor were studied in Akkeshi-ko estuary, easthern part of Hokkaido, Japan. This studied were aimed to clarify whether the dynamic and distribution pattern can be made by correlating for environmental ...

Environmental Risk Factors for Sarcoidosis [PDF]
Frontiers in Immunology, 2020 Sarcoidosis is a multisystem granulomatous disease that may affect any body organ. Sarcoidosis is associated with many environmental and occupational exposures. Because the exact immunopathogenesis of sarcoidosis is unknown, it is not known whether these exposures are truly causing sarcoidosis, rendering the immune system more susceptible to the ...

The unpredictably eruptive dynamics of spruce budworm populations in eastern Canada
Population 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 ...

Environmental risk factors for autism [PDF]
Emerging Health Threats Journal, 2011 Autism is a devastating childhood condition that has emerged as an increasing social concern just as it has increased in prevalence in recent decades. Autism and the broader category of autism spectrum disorders are among the increasingly seen examples in which there is a fetal basis for later disease or disorder. Environmental, genetic, and epigenetic

Network topology drives population temporal variability in experimental habitat networks
Population 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 ...
