Distribution patterns and corresponding dispersal outcomes of seeds following secondary wind dispersal

open access: yesEcological Indicators
Seed dispersal outcomes such as antitelechory, atelechory, telechory, and seed storage, reflect plants' functional responses in dispersal. How diaspore attributes affect seed distribution patterns and corresponding dispersal outcomes following secondary ...

Estimating response distances of lesser prairie‐chickens to anthropogenic features during long‐distance movements

open access: yesEcosphere, 2020
Spatially distributed populations often rely on large‐scale processes for long‐term population stability. These processes are driven by individuals moving across the landscape through long‐distance dispersal movements.

Invasions with Fat-Tailed and Long-Distance Dispersal

open access: yes, 2021
Thesis (Ph.D.)--University of Washington, 2021Ecologists have recognized fat-tailed and long-distance dispersal (LDD) as critical to our understanding of population spread and invasions; heavy- and fat-tailed kernels fit empirical dispersal data better ...

DNA‐Templated 2D Heterostructures as Phototriggered Dynamic Nanohybrids: From Releasing Molecular Loads to Controlling Enzyme Biocatalytic Function

open access: yesAdvanced Functional Materials, EarlyView.
DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

Long distance biotic dispersal of tropical seagrass seeds by marine mega-herbivores

open access: yesScientific Reports, 2017
Terrestrial plants use an array of animals as vectors for dispersal, however little is known of biotic dispersal of marine angiosperms such as seagrasses.

Larger Seeds are Dispersed Farther: the Long-Distance Seed Disperser ant Aphaenogaster famelica Prefers Larger Seeds

open access: yesSociobiology, 2015
Seed dispersal by ants (myrmecochory) is an important life phase in flowering herbs of temperate deciduous forests, and long dispersal is basically preferable in terms of plant fitness.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Previous reproductive success and environmental variation influence nest‐site fidelity of a subarctic‐nesting goose

open access: yesEcology and Evolution
Nest‐site fidelity is a common strategy in birds and is believed to be adaptive due to familiarity with local conditions. Returning to previously successful nest sites (i.e., the win‐stay lose‐switch strategy) may be beneficial when habitat quality is ...

Seed dispersal, herbivory and recruitment failure of Persoonia elliptica (Proteaceae) in Western Australian Jarrah (Eucalyptus marginata) forest [PDF]

open access: yes, 2012
Persoonia elliptica is a resprouting understorey tree species of the jarrah (Eucalyptus marginata) forests of South-Western Australia. All known populations are lacking in seedlings and saplings, resulting in population structures made up solely of ...

Long range dispersal and spatial pattern formation in biological invasions

open access: yes, 2006
In this paper we explore the consequences of long distance dispersal in biological invasion processes through simulations using a recently developed cellular automaton model.
