Effects of natal departure and water level on survival of juvenile snail kites (Rostrhamus sociabilis) in Florida Effects of natal departure and water level on survival of juvenile snail kites (Rostrhamus sociabilis) in Florida
Survival rate from fledging to breeding, or juvenile survival, is an important source of variation in lifetime reproductive success in birds. Therefore, determining the relationship between juvenile survival and environmental factors is essential to understanding fitness consequences of reproduction in many populations. With increases in density of individuals and depletion of food...

Resource allocation in offspring provisioning: An evaluation of the conditions favoring the evolution of matrotrophy Resource allocation in offspring provisioning: An evaluation of the conditions favoring the evolution of matrotrophy
We used analytic and simulation models to determine the ecological conditions favoring evolution of a matrotrophic fish from a lecithotrophic ancestor given a complex set of trade‐offs. Matrotrophy is the nourishment of viviparous embryos by resources provided between fertilization and parturition, while lecithotrophy describes embryo nourishment provided before fertilization. In fishes...

Uncertainty in spatially explicit animal dispersal models Uncertainty in spatially explicit animal dispersal models
Uncertainty in estimates of survival of dispersing animals is a vexing difficulty in conservation biology. The current notion is that this uncertainty decreases the usefulness of spatially explicit population models in particular. We examined this problem by comparing dispersal models of three levels of complexity: (1) an event-based binomial model that considers only the occurrence of...

In praise of mechanistically-rich models In praise of mechanistically-rich models
Quantitative models are crucial to almost every area of ecosystem science. They provide a logical structure that guides and informs empirical observations of ecosystem processes. They play a particularly crucial role in synthesizing and integrating our understanding of the immense diversity of ecosystem structure and function. Increasingly, models are being called on to predict the...

Mathematical modeling relevant to closed artificial ecosystems Mathematical modeling relevant to closed artificial ecosystems
The mathematical modeling of ecosystems has contributed much to the understanding of the dynamics of such systems. Ecosystems can include not only the natural variety, but also artificial systems designed and controlled by humans. These can range from agricultural systems and activated sludge plants, down to mesocosms, microcosms, and aquaria, which may have practical or research...

Modeling fish community dynamics in Florida Everglades: Role of temperature variation Modeling fish community dynamics in Florida Everglades: Role of temperature variation
Temperature variation is an important factor in Everglade wetlands ecology. A temperature fluctuation from 17°C to 32°C recorded in the Everglades may have significant impact on fish dynamics. The short life cycles of some of Everglade fishes has rendered this temperature variation to have even more impacts on the ecosystem. Fish population dynamic models, which do not explicitly...

Carbon isotope composition of ambient CO2 and recycling: a matrix simulation model Carbon isotope composition of ambient CO2 and recycling: a matrix simulation model
The relationship between isotopic composition and concentration of ambient CO2 in a canopy and its associated convective boundary layer was modeled. The model divides the canopy and convective boundary layer into several layers. Photosynthesis, respiration, and exchange between each layer can be simulated by matrix equations. This simulation can be used to calculate recycling; defined...
