Meyna grisea (King & Gamble) Robyns and Meyna peltata Robyns (Rubiaceae: Vanguerieae) – a new record of two ethnobotanically significant fruit trees from Manipur, India

open access: yesNordic Journal of Botany, EarlyView.
Meyna grisea and M. peltata, two new records from Imphal Valley, Manipur, India, characterised by a capitate stigma with 4–5 divergent, spreading lobes on a globose base, and a prominent peltate stigma, respectively, are described and illustrated here. Photographs, key to the species, along with their coordinates and diagnostic characters in comparison

Recognition of endophytic Trichoderma species by leaf-cutting ants and their potential in a Trojan-horse management strategy [PDF]

open access: yesRoyal Society Open Science, 2017
Interactions between leaf-cutting ants, their fungal symbiont (Leucoagaricus) and the endophytic fungi within the vegetation they carry into their colonies are still poorly understood.

Plants use macronutrients accumulated in leaf-cutting ant nests [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2006
Leaf-cutting ants ( Atta spp.) are known for their extensive defoliation in neo-tropical forests and savannahs. Debate about the costs and benefits of their activities has been largely dominated by their detrimental effects on agriculture and agroforestry.

Fire buffers drought impacts on reproduction in a resprouting Mediterranean shrub

open access: yesOikos, EarlyView.
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 ...

Open‐land‐derived agroforestry and effects of abandonment of management of the main crop on ecosystem services and woody plant diversity

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
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 ...

Population Dynamics of Acromyrmex crassispinus (Forel) (Hymenoptera: Formicidae) and Attacks on Pinus taeda Linnaeus (Pinaceae) plantations

open access: yesSociobiology, 2015
This work aimed to study the population dynamics of Acromyrmex crassispinus (Forel) in Pinus taeda L. plantations, evaluating the density and spatial distribution of nests over time, inferring about the period of the first nuptial flight of A ...

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
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.

Identity Play: Middle School Youths' Provisional Self‐Making in Horizon‐Expanding STEM Spaces

open access: yesScience Education, EarlyView.
ABSTRACT This study introduces identity play as an analytic construct for science education to explore improvisational dimensions of middle school students' STEM identity development in multiple out‐of‐school learning experiences focused on environmental problem‐solving.
