Spatial patterns as long transients in submersed-floating plant competition with biocontrol Spatial patterns as long transients in submersed-floating plant competition with biocontrol
A cellular automata model was developed and parameterized to test the effectiveness of application of biological control insects to water hyacinth (Pontederia crassipes), which is an invasive floating plant species in many parts of the world and outcompetes many submersed native aquatic species in southern Florida. In the model, P. crassipes was allowed to compete with Nuttall’s...

Visualizing wading bird optimal foraging decisions with aggregation behaviors using individual-based modeling Visualizing wading bird optimal foraging decisions with aggregation behaviors using individual-based modeling
Foragers on patchy landscapes must efficiently balance time between searching for and consuming resources to meet their daily energetic requirements. Spatial aggregation foraging behaviors may improve foraging efficiency by sharing information on locations of resource hotspots. Wading birds are an example of patch foragers that form colonial aggregations during the breeding season to...

Resource-driven pattern formation in consumer-resource systems with asymmetric dispersal on a plane Resource-driven pattern formation in consumer-resource systems with asymmetric dispersal on a plane
This paper considers resource-driven pattern formation in consumer-resource systems. Here, a planar pattern consists of many big patches, and a big patch can be regarded as combination of many patches on the plane. The consumer moves between patches asymmetrically, while the asymmetry is driven by the resource abundance. Based on experimental models with linearly-linked patches, we...

Global potential distribution of mangroves: Taking into account salt marsh interactions along latitudinal gradients Global potential distribution of mangroves: Taking into account salt marsh interactions along latitudinal gradients
Mangrove is one of the most productive and sensitive ecosystems in the world. Due to the complexity and specificity of mangrove habitat, the development of mangrove is regulated by several factors. Species distribution models (SDMs) are effective tools to identify the potential habitats for establishing and regenerating the ecosystem. Such models usually include exclusively environmental...

Ecological benefits of integrative weed management of Melaleuca quinquenervia in Big Cypress National Preserve Ecological benefits of integrative weed management of Melaleuca quinquenervia in Big Cypress National Preserve
The southern tip of North America coalesces into one of the world’s largest freshwater wetlands, the Everglades, Florida, USA. Though this region is much like an island, home to high biodiversity and endemism, it is also the site of a century of development and associated landscape-scale species invasions. Melaleuca quinquenervia (hereafter melaleuca), a tree native to tropical Australia...

Less is more: Less herbicide does more when biological control is present in Pontederia crassipes Less is more: Less herbicide does more when biological control is present in Pontederia crassipes
An experiment along with simulation modeling was applied to study the combinations of herbicide treatment and biological control that best limit invasive water hyacinth (Pontederia crassipes, formerly Eichhornia crassipes) in freshwater aquatic systems. The experiment consisted of 14 different treatments of P. crassipes in 1.67 m2 outdoor tank mesocosms. Seven treatments were with and...
