A shining starlet: Nematostella vectensis as a model for developmental, regenerative, and comparative biology

open access: yesDevelopmental Dynamics, EarlyView.
Abstract The sea anemone, Nematostella vectensis, has been used as a model organism in developmental biology studies for many years. This estuarine species has the notable capacity to regenerate its full body plan from small pieces throughout life. Nematostella have been described as having a great degree of cellular plasticity.

Interactions between Plutella xylostella, Diadegma semiclausum and some generalist predators of brassica crops. [PDF]

open access: yes, 2011
While much is known about the diamondback moth, Plutella xylostella (L.) (Plutellidae) (DBM), the most important pest of brassica crops worldwide, there is little understanding about the dynamics of predatory invertebrates in brassica systems.

Orthodentine‐osteodentine and osteocytic‐anosteocytic transition inferred from Silurian stem chondrichthyan dermal jawbones with ever‐white teeth overgrown by brown denticles

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The dentigerous jawbones of a 423‐million‐year‐old stem chondrichthyan (ischnacanthid acanthodian) carry a characteristic combination of multi‐row non‐shedding white teeth with brownish overgrowing denticles. The color distinction makes it a good model for observing the interaction between two odontode lineages, but the nature of ...

A Predator-Prey Model with an Application to Lake Victoria Fisheries [PDF]

open access: yes
Greater complexity in renewable resource models is achieved by acknowledging that species interact through a predator-prey relationship in which both species are harvested.

Data from: Behavioral hypervolumes of predator groups and predator-predator interactions shape prey survival rates and selection on prey behavior

open access: yes, 2016
Predator-prey interactions often vary on the basis of the traits of the individual predators and prey involved. Here we examine whether the multidimensional behavioral diversity of predator groups shapes prey mortality rates and selection on prey ...

Reduced size of larvae and small fish linked to warming and reduced prey density

open access: yesEcography, EarlyView.
Body size is an integrative trait that has declined across many ecological assemblages in the last decades. Changes in body size of early life stages and small‐bodied fish are driven by complex interactions between size‐dependent mortality, and temperature‐ and food‐dependent growth, and can have consequences for recruitment to the adult stock and food

Dynamical of Prey Refuge in a Diased Predator-Prey Model with Intraspecific Competition for Predator

open access: yesJTAM (Jurnal Teori dan Aplikasi Matematika)
The predator-prey model described is a population growth model of an eco-epidemiological system with prey protection and predator intraspecific traits. Predation interactions in predator species use response functions.

Disentangling functional spaces: a multidimensional framework for ecology and conservation

open access: yesEcography, EarlyView.
Trait‐based ecology often relies on a single functional space, where diverse traits are combined into one multivariate framework. While convenient, this approach risks masking ecological strategies because variance is often dominated by a few traits, such as body size.
