Farming System and Nematodes Affect the Rhizosphere Microbiome of Tropical Banana Plants

Environmental Microbiology Reports, Volume 17, Issue 4, August 2025.
The banana crops showed a core microbiome of 77 ASV, mostly belonging to Proteobacteria, Actinobacteria, and Bacilli. Specific groups of bacteria and fungi were linked to each nematode species or feeding group, with a core microbiome of correlated taxa found only when considering nematodes by feeding groups.

High soil moisture triggers negative plant–soil feedbacks in a tropical forest

Functional Ecology, Volume 39, Issue 6, Page 1469-1482, June 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant‐microbial interactions help stabilize coexistence and shape ecological communities. These interactions are sensitive to abiotic conditions, but how they may be affected by environmental change is unknown.

Still little evidence of poleward range shifts in the tropics, but lowland biotic attrition may be underway

Biotropica, Volume 57, Issue 1, January 2025.
Based on reviews of more than 450 studies, documented climate‐driven species range shifts within the terrestrial tropics have been exclusively upslope—none poleward, a pattern we attribute to the lack of latitudinal temperature gradients within the tropics, as illustrated here.

Discreet but diverse and specific: Determining plant‐herbivore interactions across a species‐rich plant family in a tropical rain forest

Biotropica, Volume 57, Issue 1, January 2025.
We conducted a year‐long study in Ecuador's Yasuní National Park, focusing on nine understory Annonaceae species to investigate herbivory patterns and herbivore‐host associations. Our findings revealed significant temporal fluctuations in leaf damage, with Anaxagorea brevipes and Unonopsis veneficiorum experiencing higher herbivore pressure, and ...

Avian phylogenetic and functional diversity are better conserved by land‐sparing than land‐sharing farming in lowland tropical forests

Journal of Applied Ecology, Volume 61, Issue 10, Page 2497-2509, October 2024.
To minimise the loss of avian phylogenetic diversity and functional traits from farming in the Amazon, it is imperative to protect large blocks of undisturbed and regenerating forests. The intensification required within existing farmlands to make space for spared lands while meeting agricultural demand needs to be sustainable, avoiding long‐term ...
