A number of recent studies have documented long-term declines in abundances important arthropod groups, primarily Europe and North America. These are generally attributed to habitat loss, but a study [B.C. Lister, A. Garcia, Proc. Natl. Acad. Sci. USA 115, E10397-E10406 (2018)] from the Luquillo Experimental Forest (LEF) Puerto Rico global warming. We analyze data LEF evaluate trends within context hurricane-induced disturbance, secondary succession, temporal variation temperature. Our...
Invasive plants are rapidly entering new ecosystems due to globalisation, increased trade, and frequent disturbances of natural habitats. Schinus terebinthifolia Raddi, known as the Brazilian peppertree, is a particularly aggressive invasive shrub in Florida, Hawaii, Texas, California. Due its growth damage it can cause ecological systems, considered one worst upland species state prompting extensive biological control efforts. The classical agent, Pseudophilothrips ichini, was approved for...
Worker size and geographical distribution of red imported fire ants (Solenopsis invicta Buren), black richteri Forel), their hybrid (S. × S. richteri) (Hymenoptera: Formicidae) were evaluated from colonies sampled across Tennessee. The ant species status determined using cuticular hydrocarbon venom alkaloid indices obtained gas chromatography mass spectrometry. Hybrids the most common throughout With exception a few isolated samples, only hybrids found in east Tennessee, predominated middle...
Abstract Chinese tallow tree ( Triadica sebifera [L.] Small) (Malpighiales: Euphorbiaceae) is one of the most invasive plants in southeastern United States and designated as a noxious weed state Florida. Current management strategies for are expensive ineffective at landscape scale, allowing further spread. Here, we document first records four scale insect species, Ceroplastes rusci (Linnaeus) (Hemiptera: Coccidae), Coccus hesperidum Linnaeus Rhizoecus floridanus Hambleton Rhizoecidae),...
Abstract With predictions of increased frequency intense hurricanes, it is increasingly crucial to understand how biotic and abiotic components forests will be affected. This study describes canopy arthropod responses repeated experimental natural opening at the Luquillo Experimental Forest Long‐term Ecological Research Site (LTER) in Puerto Rico. The trimming experiment (CTE1) treatments were started 2004, a second (CTE2) was conducted 2014, effects hurricane site. Paired disturbed plots...
Red imported fire ant (Solenopsis invicta Buren; RIFA) and black richteri Forel (Hymenoptera: Formicidae); BIFA) are considered distinct species with introgression via a reproductively functional hybrid (HIFA). The RIFA BIFA common names based on relative coloration. Due to human color perception variation, using identify RIFA, or HIFA is challenging. Fire identification traditionally involves molecular chemical techniques, but colorimetric test could allow rapid low-cost identification. In...
