Limited drought tolerance in the neotropical seasonally dry forest plants impairs future species richness

Plant Biology, EarlyView.
Global climate change will likely modify the plant assemblages of the Neotropical seasonally dry forest based on the physiological capabilities of the species. Abstract Neotropical seasonal dry forest (NSDF) is one of the most threatened ecosystems according to global climate change predictions.

Do Energetic Challenges Mimicking Missed Foraging Encourage Torpor Use by a Neotropical Bat?

Biotropica, Volume 58, Issue 2, March 2026.
We experimentally tested whether Merriam's long‐tongued bat (Glossophaga mutica), a Neotropical nectarivorous species, uses heterothermy in response to reduced energy intake. We found that energetically challenged bats maintained subcutaneous temperatures significantly closer to roost temperature during the daytime inactive period.

Soil Properties and Plant Species Identity Independently Influence Arbuscular Mycorrhizal Fungal Composition Across Lowland Tropical Forests

Biotropica, Volume 58, Issue 2, March 2026.
We found that plant species identity and soil properties, especially soil phosphorus availability, independently structured arbuscular mycorrhizal fungal (AMF) community composition in tropical forests across central Panama. We also found that soil nutrient availability may mediate the interaction networks between plants and AMF. ABSTRACT Plant species

Question the Mark: A Review and Assessment of Bat Marking Practices

Mammal Review, Volume 56, Issue 1, March 2026.
We reviewed a decade of research on bats and conducted a broader systematic review to assess the nature of bat marking practices and the effects and efficacy of marks. Effects of marks on bats, mark details and marking procedures are rarely reported and further research on the effects of marks on bats and more thorough reporting are needed.

The first comprehensive multilocus phylogeny of the lichenized genus Micarea (Ectolechiaceae, Ascomycota)

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Micarea is a crustose cosmopolitan lichen genus that belongs to the euascomycete class Lecanoromycetes. Recent molecular phylogenies on the genus based on one to three loci have mostly focused on Micarea s.str., including the type species M. prasina, and suggested that Micarea s.l. is paraphyletic.
