Niche packing, but not niche expansion, explains the co‐occurrence of hummingbirds‐visited plants

open access: yesEcography, Volume 2025, Issue 6, June 2025.
Tropical mountains often harbour high species richness. Yet the mechanisms behind such high richness remain poorly understood. One prominent hypothesis for high species richness is niche partitioning, which reduces competition and promotes coexistence.

Evolution of acoustic communication in crickets: phylogeny of Eneopterinae reveals an adaptive radiation involving high-frequency calling (Orthoptera, Grylloidea, Eneopteridae)

open access: yesAnais da Academia Brasileira de Ciências, 2004
Evolution of dominant frequencies in songs of Eneopterinae crickets was studied with respect to phylogeny. Two characters are optimized on the tree: the first describes the frequency resulting from the vibration of the harp (Fda), and the second is due ...

Differential effect of grassland mowing on arthropod taxa

open access: yesEcological Entomology, Volume 50, Issue 2, Page 288-298, April 2025.
First, we discovered that mowing had a negative effect on overall arthropod abundance in all four of our studies. Second, our four studies found that seven taxa showed only negative, four only positive, and four mixed positive and negative responses. Third, regarding taxonomic resolution, no third‐level taxon (i.e.

Mitochondrial genomes of two Sinochlora species (Orthoptera): novel genome rearrangements and recognition sequence of replication origin [PDF]

open access: yes, 2013
BACKGROUND: Orthoptera, the largest polyneopteran insect order, contains 2 suborders and 235 subfamilies. Orthoptera mitochondrial genomes (mitogenomes) follow the ancestral insect gene order, with the exception of a trnD-trnK rearrangement in ...

Ultrasonic songs and stridulum anatomy of Asiophlugis crystal predatory katydids (Tettigonioidea: Meconematinae: Phlugidini) [PDF]

open access: yes, 2020
The behavioural ecology of ultrasonic-singing katydids is not well understood, and the general bioacoustics, barely known for a few Neotropical Meconematinae, tends to be overlooked for species from Southeast Asia.
