Habitat‐related seed germination traits in alpine habitats [PDF]

open access: yesEcology and Evolution, 2017
AbstractUnderstanding the key aspects of plant regeneration from seeds is crucial in assessing species assembly to their habitats. However, the regenerative traits of seed dormancy and germination are underrepresented in this context. In the alpine zone, the large species and microhabitat diversity provide an ideal context to assess habitat‐related ...

Cover crops affect soybean yield components, but not grain quality

open access: yesAgronomy Journal, Volume 114, Issue 6, Page 3193-3205, November/December 2022., 2022
Abstract Cover cropping is mainly used to prevent soil erosion, but the effects of individual cover crops on the subsequent soybean [Glycine max (L.) Merr.] are hardly known. Therefore, two annual field trials with 15 cover crop species and bare fallow as control were conducted in semi‐arid East Austria in 2016 and 2017.

On the “Habitat” of Lophiomys [PDF]

open access: yesNature, 1880
ON reading the review of “Cassell's Natural History,” vol. iii., given in NATURE, vol. xxi. p. 136, I find that both the author and the reviewer do not appear to have been aware that the “habitat” of that most interesting rodent, Lophiomys imhausi, is well known.

Coexistence and invasibility in a two-species competition model with habitat-preference [PDF]

open access: yesJ. Theor. Bio. 265 (2010) 609-617, 2010
The outcome of competition among species is influenced by the spatial distribution of species and effects such as demographic stochasticity, immigration fluxes, and the existence of preferred habitats. We introduce an individual-based model describing the competition of two species and incorporating all the above ingredients.

Movement bias in asymmetric landscapes and its impact on population distribution and critical habitat size [PDF]

open access: yesarXiv, 2023
Ecologists have long investigated how demographic and movement parameters determine the spatial distribution and critical habitat size of a population. However, most models oversimplify movement behavior, neglecting how landscape heterogeneity influences individual movement. We relax this assumption and introduce a reaction-advection-diffusion equation

Pollen limitation of native plant reproduction in an urban landscape

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 1969-1980, December 2022., 2022
Abstract Premise Evidence suggests that bees may benefit from moderate levels of human development. However, the effects of human development on pollination and reproduction of bee‐pollinated plants are less‐well understood. Studies have measured natural variation in pollination and plant reproduction as a function of urbanization, but few have ...

Functional traits mediate individualistic species‐environment distributions at broad spatial scales while fine‐scale species associations remain unpredictable

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 1991-2005, December 2022., 2022
Abstract Premise Numerous processes influence plant distributions and co‐occurrence patterns, including ecological sorting, limiting similarity, and stochastic effects. To discriminate among these processes and determine the spatial scales at which they operate, we investigated how functional traits and phylogenetic relatedness influence the ...

The relationship between chlorophyllous spores and mycorrhizal associations in ferns: evidence from an evolutionary approach

open access: yesAmerican Journal of Botany, Volume 109, Issue 12, Page 2068-2081, December 2022., 2022
Abstract Premise Approximately 14% of all fern species have physiologically active chlorophyllous spores that are much more short‐lived than the more common and dormant achlorophyllous spores. Most chlorophyllous‐spored species (70%) are epiphytes and account for almost 37% of all epiphytic ferns.

Mesoscopic structure and social aspects of human mobility [PDF]

open access: yesPLoS ONE 7(5): e37676, 2012, 2012
The individual movements of large numbers of people are important in many contexts, from urban planning to disease spreading. Datasets that capture human mobility are now available and many interesting features have been discovered, including the ultra-slow spatial growth of individual mobility.

Optimal SNP filtering strategies for pedigree reconstruction: A case study with wild red‐spotted masu salmon population

open access: yesPopulation Ecology, EarlyView.
In this article, we tested optimal SNP filtering strategies for accurate parentage assignment and pedigree reconstruction for a wild population of red‐spotted masu salmon, Oncorhynchus masou ishikawae. We found that mid‐point filtering in terms of call rate and minor allele frequency performs well for pedigree reconstruction.
