Movement Patterns of Carabid Beetles Between Heterogenous Crop and Noncrop Habitats [PDF]

, 2018
Habitats adjacent to crop fields can increase natural enemy populations by providing additional food, shelter and overwintering sites. While many studies have focused on the role of non-crop borders for supporting natural enemies, here we investigate the

Inequalities in intraspecific plant–lemur interactions drive seed dispersal patterns

Oikos, EarlyView.
Biotic interactions occur between individuals and accumulate to shape species‐level interaction structure across a community. Skewed interaction structures, where a few individuals are highly connected and most have few interactions, are increasingly identified at the individual‐level.

Are post-dispersed seeds of Eucalyptus globulus predated in the introduced range? Evidence from an experiment in Portugal [PDF]

Web Ecology, 2018
Plantations of Eucalyptus globulus Labill. have been expanding rapidly worldwide. The species is considered invasive in several regions. While in the native range, post-dispersal seed predation is known to severely limit eucalypt recruitment, there is

Flowering schedule in a perennial plant:Life-history trade-offs, seed predation and total offspring fitness [PDF]

, 2015
Optimal timing of reproduction within a season may be influenced by several abiotic and biotic factors. These factors sometimes affect different components of fitness, making assessments of net selection difficult.

Fruit‐quality tradeoffs generate asymmetry in plant reliance on mutualistic frugivores

Oikos, EarlyView.
Seed dispersal is a fundamental ecological process influencing the evolution of plant life‐history strategies. In fleshy‐fruited plants dispersed by mutualistic frugivores, variation in fruit traits among closely related species may shape the temporal and spatial dynamics of dispersal events critical to population success.

Landscape and habitat effects on pest control and seed predation by carabid beetles

Basic and Applied Ecology
In both natural and anthropogenic environments, predation by arthropods plays a crucial role in the control of weeds and pests. Carabid beetles (Coleoptera: Carabidae) are key generalist predators feeding on a wide range of prey.

Negative phenotypic and genetic associations between copulation duration and longevity in male seed beetles [PDF]

, 2009
Reproduction can be costly and is predicted to trade-off against other characters. However, while these trade-offs are well documented for females, there has been less focus on aspects of male reproduction.

Taste and Physiological Responses to Glucosinolates: Seed Predator versus Seed Disperser

PLoS ONE, 2014
In contrast to most other plant tissues, fleshy fruits are meant to be eaten in order to facilitate seed dispersal. Although fleshy fruits attract consumers, they may also contain toxic secondary metabolites. However, studies that link the effect of fruit toxins with seed dispersal and predation are scarce.
