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

Developmental 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.

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

Developmental 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 ...

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

Ecography, 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

Predator-Prey Covariance with predator aggregative responses

, 2010
The spatial covariance between prey and predator densities is closely related to the rate of encounters, and thus to predation rates. To include the effect of covariance in dynamic predator–prey models it is useful to express the spatial covariance

Disentangling functional spaces: a multidimensional framework for ecology and conservation

Ecography, 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.

Species traits mediate terrestrial mammal density responses to human impacts

Ecography, EarlyView.
Human activities are reshaping ecosystems, but their effects on species population density remain poorly understood. Most studies focus on species presence–absence, thus limiting insight into how anthropogenic pressures affect population density. Emerging evidence suggests that responses of natural populations to human disturbance are highly variable ...

Decoupling environmental suitability from realized recruitment through ontogenetic environmental filtering in a long‐lived Mediterranean palm species

Ecography, EarlyView.
Long‐lived plants facing anthropogenic disturbance often exhibit recruitment failure despite persistent reproductive adults, generating extinction debt masked by longevity. However, whether adult presence reliably reflects environmental suitability for recruitment remains unclear.
