| description | A study of the pollination ecology of Magnolia tamaulipana and its specialized pollinator, Cyclocephala caelestís was conducted at the El Cielo Biosphere Reserve, Tamaulipas during the late spríng of 1996. Cychcaphala caelestis visited fiowers of M. tamaulipana most frequently after 2100 with males being more abundant than females. Wa report for the first time within the ganus, endothermy and thoracic temperatura regulation for C. caelestis. Thoracic temperature averaged 26.8°C ± SE = 0.3 with an excess temperatura of 4.7°C ± SE = 0.3. Males and females did not differ in mean thoracic temperatura. While within the flowers, beetles regulated their thoracic temperature índependently of ambient and floral temperaturas and were observed mating and feeding on petal tissue. Endothermy is probably important for mating and feeding activities which occur at night during cool temperatures. Petal tissue is thought to contain ethereal oils within which are dissolved chiral esters thet are responsible for floral odor and the attraction of Cyclocephala specíes. Petal and sepal tissue both contain high amounts of carbohydrata and protein, but petals contain 4x less fiber, which probably accounts for its preference as a food tissue by Cyclocephala. |

Un estudio sobre la ecología de la polinización de Magnolia tamaulipana y su polinízador, Cyclocephala caelestís, fue realizado en la Reserva de la Biósfera El Cielo, Tamaulipas, durante la primavera de 1996. Cyclocephala caelestis visitó las flores de M. tamaulipana con mayor frecuencia después de las 21:00 horas, siendo los machos más abundantes que las hembras. Citamos por primera vez dentro del género, la endotermia y reguladón da la temperatura torácica en C. caelestis. El promedio de la temperatura torácica fue de 26.8°C ± SE = 0.3 con un exceso ds 4.7°C ± SE - 0.3 sobre la temperatura ambiental. Los machos y hembras no se diferenciaron en su temperatura torácica media. En el interior de las flores, los escarabajos regularon su temperatura torácica, independientamente de las temperaturas ambiental y floral, y fueron observados apareándose y alimentándose de los pétalos. La endotermia quiza sea importante para realizar estae actividades de apareamiento y alimentación, las cuales las realizan durante la noche cuando disminuye la temperatura. Se piensa que el tejido de los pétalos contiene aceites etéreos en los que se disuelven ésteres quirales que son responsables del aroma floral y la atracción de las especies de Cyclocephala. Los tejidos de pétaloe y sépalos contierren altas cantidades de carbohidratos y proteínas, sin embargo los pétalos presentan cuatro veces menos fibra, lo que probablemente explique el porque Cyclocephala, los prefiere como alimento.
