Adaptive Nature of Insect Galls
The evolution of the galling habit has followed two pathways, one via mining plant tissues and the other from sedentary external herbivores that then modify plant growth.
Ants on plants: a meta-analysis of the role of ants as plant biotic defenses
The results suggest that ants do act as plant biotic defenses, but the effects of their presence are more pronounced in tropical systems, especially in myrmecophytic plants.
Toward an old‐growth concept for grasslands, savannas, and woodlands
We expand the concept of “old growth” to encompass the distinct ecologies and conservation values of the world's ancient grass-dominated biomes. Biologically rich grasslands, savannas, and…
A global method for calculating plant CSR ecological strategies applied across biomes world‐wide
The CSR strategies of vascular plants can be compared quantitatively within and between biomes at the global scale and the strategy–environment relationships it elucidates will help to predict which kinds of species may assemble in response to changes in biogeochemical cycles, climate and land use.
Ecology and evolution of plant diversity in the endangered campo rupestre: a neglected conservation priority
It is shown that campo rupestre is fully comparable to and remarkably convergent with both fynbos and kwongkan, and fulfills the criteria for a classic OCBIL.
Biogeographical gradients in galling species richness
The present study corroborates the hypothesis that the gall forming habit is an adaptation to harsh or stressful environments, and describes for the first time broad scale geographical patterns in galling insect species richness.
Biodiversity of galling insects: historical, community and habitat effects in four neotropical savannas
The results corroborate the hypothesis that predicts that habitat stress is the main factor generating the patterns of galling insect richness in Brazilian savannas.
Are gall midge species (Diptera, Cecidomyiidae) host-plant specialists?
It is concluded that gall morphotypes associated with information on the host plant species and attacked organs are reliable surrogates of the gall-inducing species.
Caatinga: The Scientific Negligence Experienced by a Dry Tropical Forest

Seasonally dry tropical forests (SDTFs) provide a habitat for a diverse number of species and cover significant land areas. Yet, the amount of scientific research they have attracted is minimal.…
Global patterns in local number of insect galling species
Over 280 samples of local species of galling herbivorous insects from fourteen countries on all continents except Antarctica revealed a strong pattern of highest richness in warm temperate latitudes, or their altitudinal equivalents, and results were consistent with the hypothesis.
