Complete genome sequence of Planctomyces limnophilus type strain (Mü 290). [PDF]

open access: yes, 2010
Planctomyces limnophilus Hirsch and Müller 1986 belongs to the order Planctomycetales, which differs from other bacterial taxa by several distinctive features such as internal cell compartmentalization, multiplication by forming buds directly from the ...

Texas coastal zone biotopes : an ecography : interim report for the Bay and Estuary Management Program (CRMP) [PDF]

open access: yes, 1972
November 1972Because esthetics, biological environment and physiography are so interrelated and have changeable meanings in various environments, we are obligated to think of the environment in terms of biological change, as environmental protection is ...

Habitat‐based spatial patterns enable realistic reconstruction of plant spatial arrangements across complex landscapes

open access: yesOikos, EarlyView.
Spatially explicit individual‐based models provide a powerful way to explore spatial dynamics when direct observation is not feasible. But for many ecological applications, these models require detailed data on the initial spatial arrangement and traits of individuals – information rarely available in large, heterogeneous or novel landscapes.

Osmotic adjustment in sessile oak seedlings in response to drought [PDF]

open access: yesAnnales des Sciences Forestières, 1997
Effets d'une sécheresse édaphique sur l'ajustement osmotique de jeunes plants de chêne. Des plants de chêne aessile âgés de 3 ans ont été soumis à des déficits hydriques se développant à deux vitesses (0,050 et 0,013 MPa·jour-1), obtenus en croisant deux niveaux d'irrigation et de compétition herbacée.

Speciation with gene flow

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Biodiversity is threatened by human activities, with extinction debt accumulating rapidly. Many of these activities change the connectivity of populations, fragmenting existing population systems or bringing previously isolated populations or species into contact.

Edges as ecological filters: Asymmetrical orientation‐specific arthropod activity across forest boundaries

open access: yesInsect Science, EarlyView.
Moderate retention forestry creates structurally sharp forest edges that act as ecological filters, shaping orientation‐specific activity of ground‐dwelling arthropods. Using drift‐fence pitfall traps, we show that activity aligned with ecotones is more frequent than activity across forest–clearcut boundaries, particularly among detritivores.

Epiphyte metapopulation dynamics are explained by species traits, connectivity, and patch dynamics [PDF]

open access: yes, 2012
The colonization-extinction dynamics of many species are affected by the dynamics of their patches. For increasing our understanding of the metapopulation dynamics of sessile species confined to dynamic patches, we fitted a Bayesian incidence function ...
