Sperm mixing in the polyandrous leaf-cutting ant Acromyrmex echinatior [PDF]
The insemination of queens by sperm from multiple males (polyandry) has evolved in a number of eusocial insect lineages despite the likely costs of the behavior.

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub
Fire and drought increasingly co‐occur, exposing plants to greater drought stress during post‐fire resprouting. Yet, the effect of this combination of disturbances on plant fitness remains poorly understood. Here, we examine how post‐fire resprouting influences reproductive success under drought conditions in the Mediterranean shrub Anthyllis ...

Putting the waste out: a proposed mechanism for transmission of the mycoparasite Escovopsis between leafcutter ant colonies [PDF]
The attine ant system is a remarkable example of symbiosis. An antagonistic partner within this system is the fungal parasite Escovopsis, a genus specific to the fungal gardens of the Attini.

Tropical forests are rapidly declining. One promising strategy to reverse the loss of tropical forest is the establishment of agroforestry on open land. We combined interviews with biodiversity surveys to learn general lessons from success and nonsuccess stories of the establishment of open‐land‐derived coffee agroforests in one of the world's ...

Association between Pseudonocardia symbionts and Atta leaf-cutting ants suggested by improved isolation methods [PDF]
Fungus-growing ants associate with multiple symbiotic microbes, including Actinobacteria for production of antibiotics.The best studied of these bacteria are within the genus Pseudonocardia, which in most fungus-growing ants are conspicuouslyvisible on ...

The continuing significance of chiral agrochemicals
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Collective action in ant control: [PDF]
Leaf-cutting ants (Atta. cephalotes) represents a serious problem to farmers in many parts of Latin America and accounts of ants eating up a whole cassava plot or destroying one or more fruit trees overnight are not uncommon.
