Hybridization as a facilitator of species range expansion [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2016
Explaining the evolution of species geographical ranges is fundamental to understanding how biodiversity is distributed and maintained. The solution to this classic problem in ecology and evolution remains elusive: we still do not fully know how species geographical ranges evolve and what factors fuel range expansions.

Effectively control negative thermal expansion of single-phase ferroelectrics of PbTiO3-(Bi,La)FeO3 over a giant range [PDF]

, 2013
Control of negative thermal expansion is a fundamentally interesting topic in the negative thermal expansion materials in order for the future applications. However, it is a challenge to control the negative thermal expansion in individual pure materials

Modelling the effect of habitat fragmentation on range expansion in a butterfly [PDF]

, 2009
There is an increasing need for conservation programmes to make quantitative predictions of biodiversity responses to changed environments. Such predictions will be particularly important to promote species recovery in fragmented landscapes, and to ...

The short range expansion

Advances in Applied Mathematics, 1983
It is shown that the Schrödinger Hamiltonian \(H_{\epsilon}=-\Delta +\epsilon^{-2}\sum^{n}_{j=1}\lambda_ j(\epsilon)V_ j((1/\epsilon)(.-x_ j))\quad on\quad L^ 2({\mathbb{R}}^ 3),\) where \(\lambda_ j\) is analytic, \(\lambda_ j(0)=1\), \(V_ j\) satisfies \((1+|\cdot |)^ 2V_ j\in R\cap L^ 1({\mathbb{R}}^ 3)\) (R being the Rollnik class), converges in ...

Microbial Range Expansions on Liquid Substrates [PDF]

Physical Review X, 2019
Despite the importance that fluid flow plays in transporting and organizing populations, few laboratory systems exist to systematically investigate the impact of advection on their spatial evolutionary dynamics. To address this problem, we study the morphology and genetic spatial structure of microbial colonies growing on the surface of a nutrient ...

The chestnut growing hotspot of Turkey in danger: introduction of the Asian chestnut gall wasp into Aegean region

Turkish Journal of Forestry, 2021
Asian chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera, Cynipidae), is an important pest of Castanea species worldwide. Adults emerge in summer and lay eggs in a few days. Severe infestations may reduce chestnut and timber production.

The Mediterranean-Pontian Argiope bruennichi (Scopoli, 1772) in Poland – overview of traits favouring range expansion

European Journal of Ecology
Due to climate warming the distribution of Southern European species has extended to the north in recent years. Currently, Argiope bruennichi (Scopoli, 1772) is distributed over the whole territory of Poland.

Effective-Range Expansion with a Long-Range Force

Physical Review Letters
The validity range of the time-honored effective range expansion can be very limited due to the presence of a left-hand cut close to the two-particle threshold. Such a left-hand cut arises in the two-particle interaction involving a light particle exchange with a small mass or a mass slightly heavier than the mass difference of the two particles ...

Impacts of Climate Change on Densities of the Urchin Centrostephanus rodgersii Vary among Marine Regions in Eastern Australia

Diversity, 2023
The urchin Centrostephanus rodgersii is expanding its range southward in eastern Australia, which has been associated with negative ecological impacts, including shifts from kelp forests to barrens.
