Seed dispersal in six species of terrestrial orchids in Biebrza National Park (NE Poland)

Acta Societatis Botanicorum Poloniae, 2017
Knowledge about seed dispersal is required to explain problems in ecology, phylogeography, and conservation biology. Even though seed dispersal is a fundamental mechanism to understand problems at different levels of biological organization (individual ...

Stratified dispersal and increasing genetic variation during the invasion of Central Europe by the western corn rootworm, Diabrotica virgifera virgifera [PDF]

, 2010
Invasive species provide opportunities for investigating evolutionary aspects of colonization processes, including initial foundations of populations and geographic expansion.

Geographic distance affects dispersal of the patchy distributed greater long-tailed hamster (Tscherskia triton). [PDF]

PLoS ONE, 2014
Dispersal is a fundamental process in ecology influencing the genetic structure and the viability of populations. Understanding how variable factors influence the dispersal of the population is becoming an important question in animal ecology.

Long-Distance Wind-Dispersal of Spores in a Fungal Plant Pathogen: Estimation of Anisotropic Dispersal Kernels from an Extensive Field Experiment [PDF]

, 2014
Given its biological significance, determining the dispersal kernel (i.e., the distribution of dispersal distances) of spore-producing pathogens is essential. Here, we report two field experiments designed to measure disease gradients caused by sexually-

Patterns, causes, and consequences of marine larval dispersal [PDF]

, 2015
Quantifying the probability of larval exchange among marine populations is key to predicting local population dynamics and optimizing networks of marine protected areas. The pattern of connectivity among populations can be described by the measurement of

Niche shifts after long-distance dispersal events in bipolar sedges (Carex, Cyperaceae) [PDF]

, 2017
PREMISE OF THE STUDY: Bipolar species represent the greatest biogeographical disjunction on Earth, raising many questions about the colonization and adaptive processes behind such striking distribution.

Sensitivity of habitat network models to changes in maximum dispersal distance.

PLoS ONE, 2023
Predicting the presence or absence (occurrence-state) of species in a certain area is highly important for conservation. Occurrence-state can be assessed by network models that take suitable habitat patches as nodes, connected by potential dispersal of ...

Spatially mixed crops to control the stratified dispersal of airborne fungal diseases [PDF]

, 2010
Intraspecific crop diversification is thought to be a possible solution to the disease susceptibility of monocultured crops. We modelled the stratified dispersal of an airborne pathogen population in order to identify the spatial patterns of cultivar ...

Spatial heterogeneities of human-mediated dispersal vectors accelerate the range expansion of invaders with source–destination-mediated dispersal

Scientific Reports, 2020
Rapid range expansions of invasive species are a major threat to ecosystems. Understanding how invasive species increase their habitat ranges and how environmental factors, including intensity of human activities, influence dispersal processes is an ...

Phenotypic and environmental correlates of natal dispersal in a long-lived territorial vulture

Scientific Reports, 2021
Natal dispersal, the movement between the birth and the first breeding site, has been rarely studied in long-lived territorial birds with a long-lasting pre-breeding stage.
