Howler monkey foraging ecology suggests convergent evolution of routine trichromacy as an adaptation for folivory

Ecology and Evolution, Volume 7, Issue 5, Page 1421-1434, March 2017., 2017
Primates possess remarkably variable color vision, and the ecological and social factors shaping this variation remain heavily debated. Here, we examine opsin genes, feeding behaviors, and reflectance of dietary foliage of wild mantled howler monkeys (Alouatta palliata).

Effect of method of preservation on the chemical composition of Enterolobium cyclocarpum leaves

Nigerian Journal of Animal Production, 2020
Enterolobium cyclocarpum leaves are less acceptable by ruminants due to their high contents of anti-nutritional factors. The effect of preserving Enterolobium cyclocarpum leaves as hay and silage or silage: hay combinations on the proximate, fibre fractions, anti-nutritional factors, minerals and vitamins compositions were investigated in this study ...

Physiological and Growth Responses of Tropical Dry Forest Tree Seedlings to Water and Nutrient Additions: Comparisons Between Nitrogen Fixers and Non‐Fixers

Biotropica, Volume 57, Issue 5, September 2025.
This study examined the physiological and growth responses of tropical dry forest tree seedlings to water and nutrient additions, comparing nitrogen (N)‐fixing and non‐fixing species. The results showed that N‐fixing species responded more strongly to nutrient addition, accumulating significantly more biomass and increasing height growth rate. Overall,

Effects of Adding Multiwall Carbon Nanotubes on Performance of Polyvinyl Acetate and Urea‐Formaldehyde Adhesives in Tropical Timber Species

Journal of Nanomaterials, Volume 2015, Issue 1, 2015., 2015
Multiwall carbon nanotubes (MWCNTs) functionalized with hydroxyl groups (MWCNTs‐OH) have been incorporated into polyvinyl acetate (PVAc) and urea‐formaldehyde (UF) adhesives utilized in tropical wood gluing. The Raman spectroscopy, the atomic force microscopy (AFM), and transmission electron microscopy (TEM) were used to describe the MWCNTs‐OH.
