Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

ABSTRACT Shell middens in Gippsland along the eastern half of Victoria's coastline have usually been characterised as small, short‐duration camp sites with relatively low shell densities and low taxonomic diversity. Here we present new excavation results from a dense, high‐diversity site at Red Bluff near the eastern end of GunaiKurnai Country, a ...

Compressible Shallow Granular Flow over a Rough Plane
Most existing depth-averaged granular flow theories assume that dry, cohesionless granular materials are incompressible, with the void ratio among grains remaining spatially and temporally invariant.

‘Where are the adults?’: Troubling child‐activism and children's political participation
Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

The spread of non‐native species
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Existence of entire solutions for non-local delayed lattice differential equations
In this article we study entire solutions for a non-local delayed lattice differential equation with monostable nonlinearity. First, based on a concavity assumption of the birth function, we establish a comparison theorem.

Energy Landscapes in Chemical Reactions and Transport
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

This paper deals with the existence of traveling wave fronts of spatially discrete reaction-diffusion equations with delay on lattices with general dimension. A monotone iteration starting from an upper solution is established, and the sequence generated
