Urban Cepaea nemoralis snails are less likely to have nematodes trapped within their shells

The paper examines how urbanization affects nematode trapping in Cepaea nemoralis snails, finding reduced encapsulation rates and a link between snail size and nematode presence.

Shifts in colour morph frequencies along an urbanisation gradient in the ground beetle Pterostichus madidus

The paper examines shifts in colour morph frequencies of Pterostichus madidus along an urbanisation gradient, finding black-legged individuals more frequent in urban areas.

Life-history traits, pace of life and dispersal among and within five species of Trichogramma wasps: a comparative analysis

This study examines life-history traits and dispersal in five Trichogramma wasp species, finding interspecific but not within-species covariation along a pace-of-life axis.

Morph-dependent nematode infection and its association with host movement in the land snail Cepaea nemoralis (Mollusca, Gastropoda)

The paper investigates how nematode infection and host movement are linked in Cepaea nemoralis snails, finding that darker morphs have fewer nematodes and infected snails show reduced activity.

Individual variation in dispersal, and its sources, shape the fate of pushed vs. pulled range expansions

This study uses simulation models to show how individual variation in dispersal and its density dependence influence whether range expansions are pulled or pushed.

Dispersal syndrome and landscape fragmentation in the salt-marsh specialist spider Erigone longipalpis

The study examines dispersal syndrome and landscape fragmentation in the salt-marsh spider Erigone longipalpis, finding no landscape-driven differences in dispersal traits but evidence of within-family phenotypic correlations.

Maternal age affects equine Day 8 embryo gene expression both in trophoblast and inner cell mass

This study examines how maternal age impacts gene expression in equine Day 8 embryos, identifying differences in mitochondrial and metabolic pathways in both trophoblast and inner cell mass.

Landscape connectivity alters the evolution of density-dependent dispersal during pushed range expansions

The paper examines how landscape connectivity affects phenotypic evolution during range expansions, finding that high connectivity can alter density-dependent dispersal, potentially slowing or reversing the transition from pushed to pulled dynamics.

Boldness and exploration vary between shell morphs but not environmental contexts in the snail Cepaea nemoralis

The paper examines whether shell morph in Cepaea nemoralis is associated with behavioral traits like boldness and exploration, finding consistent differences between morphs but no effect of thermal environment.

Individual heterogeneity and its importance for metapopulation dynamics.

The paper tests how landscape connectedness and phenotypic spatial organization affect metapopulation dynamics in spider mites, finding that self-organizing phenotypic structures improve persistence despite theoretical expectations.

Shifts from pulled to pushed range expansions caused by reduction of landscape connectivity

This study shows that reducing landscape connectivity can shift range expansions from pulled to pushed dynamics in parasitoid wasps, affecting genetic diversity and expansion speed.

Increased population density depresses activity but does not influence emigration in the snail Pomatias elegans

This study examines emigration and activity behavior in the snail Pomatias elegans under varying population densities, finding no density effect on emigration but reduced activity in response to crowding.

The distinct phenotypic signatures of dispersal and stress in an arthropod model: from physiology to life history

The paper examines metabolic and life-history differences between dispersing and resident spider mites under stress, finding no interaction between dispersal and stress exposure.

Dispersers are more likely to follow mucus trails in the land snail Cornu aspersum

The paper shows dispersers in Cornu aspersum follow mucus trails more than expected, reducing dispersal costs by guiding them to existing patches.

Kin competition accelerates experimental range expansion in an arthropod herbivore

The paper shows that kin competition can accelerate range expansion in spider mites through plastic dispersal responses, highlighting its importance in range dynamics.

Individual boldness is life stage-dependent and linked to dispersal in a hermaphrodite land snail

The paper examines how boldness and dispersal vary with life stage in the land snail Cornu aspersum, finding subadults are bolder and more dispersive than adults.
