Interaction of Seed Dispersal and Environmental Filtering Affects Woody Encroachment Patterns in Coastal Grassland [PDF]

, 2019
Encroachment of woody plants into grasslands has occurred worldwide and includes coastal ecosystems. This conversion process is mediated by seed dispersal patterns, environmental filtering, and biotic interactions.

Dispersal of the Common Cutworm, Spodoptera litura, Monitored by Searchlight Trap and Relationship with Occurrence of Soybean Leaf Damage

Insects, 2020
The common cutworm, Spodoptera litura Fabricius (Lepidoptera: Noctuidae) is a major pest of soybean. Pheromone traps are used to monitor male adults, but the catch peaks do not always predict leaf damage in soybean fields.

Larval Behavior and Longevity in the Cold-Water Coral Lophelia pertusa Indicate Potential for Long Distance Dispersal

Frontiers in Marine Science, 2017
The life cycle of many marine benthic species includes a pelagic larval stage that governs the connectivity between populations. Larval transport is a function of hydrodynamic and biological processes. Knowledge of how larval traits affect dispersal will

Changing Microarthropod Communities in Front of a Receding Glacier in the High Arctic

Insects, 2020
This study was carried out at Ny-Ålesund on Spitsbergen in Svalbard (High Arctic). Eight study sites were established along a transect from the fjord to the snout of the glacier. The sites differed from each other by the type of vegetation cover and soil

Male-killing endosymbionts: influence of environmental conditions on persistence of host metapopulation [PDF]

, 2008
Background: Male killing endosymbionts manipulate their arthropod host reproduction by only allowing female embryos to develop into infected females and killing all male offspring.

Mathematical Modelling of Mosquito Dispersal in a Heterogeneous Environment. [PDF]

, 2012
Mosquito dispersal is a key behavioural factor that affects the persistence and resurgence of several vector-borne diseases. Spatial heterogeneity of mosquito resources, such as hosts and breeding sites, affects mosquito dispersal behaviour and ...

Finding a Home: Stopping Theory and Its Application to Home Range Establishment in a Novel Environment

Frontiers in Conservation Science, 2021
Familiarity with the landscape increases foraging efficiency and safety. Thus, when animals are confronted with a novel environment, either by natural dispersal or translocation, establishing a home range becomes a priority.

Using neutral cline decay to estimate contemporary dispersal: a generic tool and its application to a major crop pathogen [PDF]

, 2013
Dispersal is a key parameter of adaptation, invasion and persistence. Yet standard population genetics inference methods hardly distinguish it from drift and many species cannot be studied by direct mark-recapture methods.

Development of morphology and swimming in larvae of a coral-reef fish, the royal gramma, Gramma loreto (Grammatidae: Teleostei)

Scientia Marina, 2012
We used reared larvae of Gramma loreto sized 5.5 to 10.5 mm to study ontogeny of morphology and swim- ming. The larvae are slender to moderate in depth, with laterally compressed bodies, about 28 myomeres, a coiled gut that is not compact, extending to

Conservation Actions in Multi-Species Systems: Species Interactions and Dispersal Costs

Frontiers in Ecology and Evolution, 2021
We use the General Equilibrium Ecosystem Model (GEEM) parameterized to Wyoming sagebrush to explore the impact of two common simplifications in bio-economic policy frameworks on species conservation decisions.
