Will climate change reduce the effects of a pesticide on amphibians?: partitioning effects on exposure and susceptibility to contaminants
TLDR
This work isolated the effects of a temperature gradient on susceptibility (toxicity at a controlled exposure duration) and exposure of the streamside salamander, Ambystoma barbouri, to the herbicide atrazine to highlight the importance of explicitly considering how climate change will affect both exposure and toxicity to contaminants to accurately assess risk.

Moving forward in circles: challenges and opportunities in modelling population cycles.
TLDR
By gaining better insight into the drivers of population cycles, the authors can begin to understand the causes of cycle gain and loss, how biodiversity interacts with population cycling, and how to effectively manage wildly fluctuating populations, all of which are growing domains of ecological research.

Sex-specific plant responses to light intensity and canopy openness: implications for spatial segregation of the sexes
TLDR
It is hypothesized that males are adapted to higher light intensity and are better able to tolerate water stress than females, as is the case with seed plants, and that males might be more responsive to waterstress than females. Expand
Tolerance responses to herbivory: implications for future management strategies in potato
TLDR
This work aggregated data from published studies and quantified the effects of variety, maturity group, life stage and defoliation mechanisms on damage thresholds to inform a tolerance-based management strategy for potato. Expand
The impact of asexual and sexual reproduction in spatial genetic structure within and between populations of the dioecious plant Marchantia inflexa (Marchantiaceae)
TLDR
This study demonstrates that studying only the sexes and not their genotypes can limit the understanding of the extent to which reproductive modes (sexual or asexual) influence genetic structure both within and between populations. Expand
Maintenance of the sexes and persistence of a clonal organism in spatially complex metapopulations
TLDR
It is found that at intermediate distances between populations, metapopulations maintained both sexes, and the spatial arrangement of populations changed the threshold at which one sex was lost, which can help explain geographic parthenogenesis and the distribution of asexual populations, the persistence of a sexual species, and inform the conservation of clonal organisms.

A Comparison of Seed Predation, Seed Dispersal, and Seedling Herbivory in Oak and Hickory: Species with Contrasting Regenerating Abilities in a Bluegrass Savanna—Woodland Habitat
TLDR
It is suggested that seed-predation prevents regeneration of oaks in this endangered community of Kentucky through predation on the acorns and browsing of seedlings. Expand
Overgrowth competition, fragmentation and sex-ratio dynamics: a spatially explicit, sub-individual-based model.
TLDR
A spatially explicit, sub-individual-based model is derived that Dynamics of sex-specific growth qualitatively resemble those generated by differential-equation models, suggesting that this much simpler framework may be adequate for multi-patch metapopulation models. Expand
Persistence of the sexes in metapopulations under intense asymmetric competition
TLDR
A population model capable of simulating the dynamics of sex-specific life-history stages within frequently disturbed patches and across a multipatch system strongly influenced by extinction and colonization is constructed. Expand
The dispersal process of asexual propagules and the contribution to population persistence in Marchantia (Marchantiaceae).
TLDR
By integrating multiple experiments to quantify the effects of gemmae on metapopulation dynamics, this work found that different stages of dispersal can lead to different conclusions on which sex has an advantage. Expand
