A soil-nesting invasive ant disrupts carbon dynamics in saplings of a foundational ant-plant

Patrick D. Milligan et al.

Summary: The study shows that the common behavior of invasive ants, such as nesting near roots, can directly reduce carbon fixation and storage of Acacia drepanolobium saplings, affecting plant growth and development.

A critical comparison of integral projection and matrix projection models for demographic analysis

Daniel F. Doak et al.

Summary: Researchers have found that IPMs may be more statistically efficient, biologically realistic, and accurate than classic matrix models, but there is little evidence to suggest that discrete vital rate estimation is less accurate than continuous functions across a wide range of sample sizes or size classes. Additionally, empirical sample sizes generally matter more than modeling approach for the accuracy of demographic outputs.

Density dependence and the spread of invasive big-headed ants (Pheidole megacephala) in an East African savanna

Alejandro G. Pietrek et al.

Summary: Supercolonial ants like the invasive big-headed ant can achieve extremely high densities, but population growth rates decline with increasing abundance due to weakened density dependence. Factors such as rainfall and tree density have minor effects on ant population dynamics. The spread rate of big-headed ants is around 50 meters per year, comparable to other supercolonial ants. Monitoring of ant abundance in invaded sites may help to understand the widespread collapse of invasive ant populations.

Browsing wildlife and heavy grazing indirectly facilitate sapling recruitment in an East African savanna

Eric M. LaMalfa et al.

Summary: The study found that wildlife had a positive effect on sapling growth while moderate cattle grazing did not have a significant impact. Grass removal treatments and neighborhood tree effects on saplings were strongest during above-average rainfall years.
