O volume, a densidade básica e o peso da matéria seca da madeira de oitenta e quatro árvores, de sete famílias de polinização aberta, procedência de Mountain Pine Ridge (MPR), Belize, de Pinus tecunumanii (Schwd) Eguiluz e Perry foram estimados aos 12 e 17 anos de idade em experimento instalado em Planaltina, Distrito Federal. Para todos os parâmetros avaliados, houve diferenças significativas entre famílias, exceto para densidade básica, medidas aos 17 anos de idade. Aos 12 anos de idade, foram testados dois métodos de avaliação para densidade básica da madeira; um com os três melhores indivíduos da parcela, e outro com todos indivíduos da parcela. As médias de densidade foram de 0,425 g/cm3 e 0,424 g/cm3, praticamente iguais para as duas amostragens. A correlação da densidade básica entre as idades foi positiva e significativa, mostrando um ganho de 0,031 g/cm3 em 5 anos. A herdabilidade da densidade básica calculada aos 12 anos de idade, em nível individual, para família e dentro de família, considerando-se a amostragem com três e seis indivíduos, foi de respectivamente 0,43, 0,81, 0,33 e 0,47, 0,63, 0,37. Como conclusão, as seleções para densidade básica devem ser feitas preferencialmente em idades quando a competição entre os indivíduos ainda não atingiu níveis elevados. Ganhos consideráveis podem ser obtidos na seleção de indivíduos ou famílias dentro da população de MPR, Belize, na região do Cerrado. Será necessário trabalhar com populações de maior base genética.

Several collections of pupae and adults of Simuliid Diptera were made in British Honduras between 9th January and 18th February 1958. Samples were collected in the Mountain Pine Ridge and El Cayo areas in the west, and along the highway traversing the eastern part of the country between Caves Branch and Stann Creek.Thirteen species of Simulium were found, nine of which are named, including S. quadrivittatum Lw. and S. metallicum Bellardi which are very annoying biters. A, few observations on distribution and habits are recorded.Of the two anthropophilic species of Simulium found, one is known to be a vector of onchocerciasis, if only of secondary importance, and the capability of the other to transmit the disease is unknown. The disease has apparently never been established in British Honduras and is present in Guatemala. The risk of infection to settlers moving into territory near Guatemala cannot be assessed without detailed knowledge of the epidemiology of the disease in Central America.

AbstractA small ruin of presumed ancient Maya origin is described. This ruin is the only certain prehistoric structure discovered on the Mountain Pine Ridge of British Honduras, and it is associated with a natural granite outcrop of monumental appearance in such a way as to suggest that the two formed a shrine of a type not previously reported in Lowland Maya archaeology.

The dwarf mistletoe Arceuthobium hawksworthii D. Wiens & C. G. Shaw (Viscaceae) has only been reported from the Mountain Pine Ridge area of Belize (1). We observed this dwarf mistletoe parasitizing its principal host, Caribbean pine (Pinus caribaea Morelet var. hondurensis (Senecl.) Barrett & Golf.) (1), 10 km east of Gualaco, Department Olancho, Honduras (elevation 800 m). Several trees were severely infected, and some dwarf mistletoe-associated mortality was observed at this location. The identification of A. hawksworthii was confirmed by comparing specimens collected from Honduras with specimens from Belize, which are deposited at the Deaver Herbarium, Northern Arizona University, Flagstaff. The mistletoes Psittacanthus angustifolius Kuijt and P. pinicola Kuijt (Loranthaceae) were also observed at this location parasitizing Caribbean pine. However, infection by both of these mistletoes was not severe, and no mistletoe-associated mortality was observed. Specimens of these mistletoes from Caribbean pine have been deposited at the Herbario, Escuela Nacional de Ciencias Forestales, Siguatepeque, Honduras. To our knowledge, this is the first report of A. hawksworthii from Honduras and extends its range approximately 350 km to the east-southeast of the Mountain Pine Ridge in Belize. This is also the first report P. angustifolius on Caribbean pine, but P. pinicola commonly infects this host in northern Honduras and Belize (2). References: (1) F. G. Hawksworth and D. Wiens.
