Relationships among the subfamilies of Chrysomelidae inferred from small subunit ribosomal DNA and morphology, with special emphasis on the relationship among the flea beetles and the Galerucinae.
Systematics and Some Aspects of the Biology of the Scorpions (Arachnida) of the Greater Puerto Rico Region: A Biosystematic Synopsis
- J. Santiago-Blay
- 30 June 2009
ABSTRACT: Eight new species of scorpions are briefly described for the Greater Puerto Rico Region. The new species are: Cazierius tatae (Diplocentrinae), Centruroides jorgeorum, C. mariaorum, C.… Expand
A Probable Pollination Mode Before Angiosperms: Eurasian, Long-Proboscid Scorpionflies
Long-Lost Pollinators The rise of angiosperms in the Early Cretaceous (∼140 million years ago) was accompanied by coevolution of a variety of insects, including flies, bees, and wasps required for… Expand
Paleontology of leaf beetles
- J. Santiago-Blay
The fossil record of the Chrysomelidae can be tentatively traced back to the late Paleozoic to early Mesozoic (Triassic). Mesozoic records (at least 9 subfamilies, 19 genera, and 35 species), are… Expand
Chemical signatures of fossilized resins and recent plant exudates.
Amber is one of the few gemstones based on an organic structure. Found over most of the world, it is the fossil form of sticky plant exudates called resins. Investigation of amber by modern… Expand
Characterization of Eucalyptus and Chemically Related Exudates by Nuclear Magnetic Resonance Spectroscopy
Exudates from six species of the genus Eucalyptus and one of the genus Corymbia (formerly Eucalyptus), from the family Myrtaceae, have been characterized by solid-state 13C and solution 1H NMR… Expand
DISTINGUISHING AMBER AND COPAL CLASSES BY PROTON MAGNETIC RESONANCE SPECTROSCOPY
Fossilized resin, or amber, has been examined from 120 worldwide sources by 1D and 2D proton magnetic resonance spectroscopy in solution. These spectra fall into five categories, corresponding to the… Expand
Jumping flea beetles: structure and performance (Insecta, Chrysomelidae, Alticinae).
Chromosomes of Some Puerto Rican Disonychina and Oedionychina (Coleoptera: Chrysomelidae: Alticinae: Oedionychini): Evolutionary Implications
Bechyn6 and Springlovi de Bechyn6 (1966) divided the tribe Oedionychini into the subtribes Disonychina and Oedionychina based, mainly, on thoracic and hind tarsal structures. This classification is… Expand
