Tropical dry forests are threatened by invasive species. [...] Key Method To assess HCM infestation, we created a numerical infestation index with six categories, ranging from uninfested and healthy, to heavily infested cacti (0–5) based on the number and size of tumors. Flower and fruit production of P. royenii was observed at three sites, while the survival of all cactus species was observed at twelve sites for 2 years. Mortality of all cacti species increased with severe HCM infestation. Mortality was…Expand

Natural Enemies of the Harrisia Cactus Mealybug and Other Hypogeococcus Species (Hemiptera: Pseudococcidae) in Puerto Rico: Identification and Taxonomic Notes on Primary and Secondary Parasitoids
Primary and secondary parasitoids of Hypogeococcus spp. (Hemiptera: Pseudococcidae) on Cactaceae, Amaranthaceae, and Portulacaceae were reported from field surveys conducted in Puerto Rico, USA,Expand
Contrasting Effects of the Invasive Hypogeococcus sp. (Hemiptera: Pseudococcidae) Infestation on Seed Germination of Pilosocereus royenii (Cactaceae), a Puerto Rican Native Cactus
It is suggested that when the HCM infestation is light, the host might be reallocating resources towards developing defensive responses, in contrast, when the infested plant is severe, the hosts might beReallocated resources toward increasing germination. Expand
Effects of fire on native columnar and globular cacti of Puerto Rico: a case study of El Faro, Cabo Rojo
Because extensive tissue damage and environmental alterations were observed during the post-fire survey, it is argued there will be significant delayed mortality and that the mortality estimates presented here are conservative. Expand
Preventive Effect of Opuntiol, Isolated from Opuntia ficus indica (L. Mill), Extract Against Ultraviolet A Radiation-Induced Oxidative Damages in NIH/3T3 Cells
Aim: We investigated the role of opuntiol, isolated from Opuntia ficus indica, against ultraviolet A waveband-mediated oxidative damages in the mouse embryonic fibroblast cell lines (NIH‐3T3).Expand


Studies on the Biology of Hypogeococcus pungens (sensu stricto) (Hemiptera: Pseudococcidae) in Argentina to Aid the Identification of the Mealybug Pest of Cactaceae in Puerto Rico
It is proposed that the population introduced to Australia is neither Hypogeococcus festerianus Lizer y Trelles nor H. pungens, but an undescribed species with three circuli, and that the HypoGEococcus pest of cacti in Puerto Rico is not H.pungens. Expand

Natural History Notes for the Columnar, Globular and Semi-Epiphytic Cactus Species of the Island of Puerto Rico
Habitat preferences for each cactus species are identified; the incidence of fires and the invasion of grasses in these habitats are recorded; and different threats to the Puerto Rican native cacti and dry forests are identified. Expand
Comparative pollination biology of Venezuelan columnar cacti and the role of nectar-feeding bats in their sexual reproduction.
The pattern of floral visitation through the night was significantly correlated with the pattern of nectar production and nectar sugar concentration for all species of cactus, and the hypothesis that Venezuelan species of columnar cacti have evolved toward specialization on bat pollination is supported.
