Efficacy of Distance-Based EMS Education in a Low-Resource Country.
CONCLUSIONS: This synchronously presented distance-based EMS educational program showed gains in both immediate and delayed knowledge acquisition among a small sample size. These results show promise that online, distance-based education is a viable option for continuing graduate medical education in low-resource countries.

The Botfly, A Tropical Menace: A Distinctive Myiasis Caused by Dermatobia hominis
AbstractDermatobia hominis, also known as the human botfly, is native to tropical and subtropical Central and South America and seen in travelers from endemic to temperate regions including the United States and Europe. Cutaneous infestation botfly myiasis involves the development ofD. hominis larvae in the skin and is common in tropical locations. The distinct appearance of a cutaneousD. hominis infestation facilitates early diagnosis and intervention where cases are common. However, the identification ofD. hominis in temperate regions may prove challenging due to its rarity.D. hominis may be misdiagnosed as folliculitis,...

Depth Influences Symbiodiniaceae Associations Among Montastraea cavernosa Corals on the Belize Barrier Reef
In Belize, shallow populations (10 and 16 m) of the coral species Montastraea cavernosa from the back reef and reef crest are genetically differentiated from deeper populations on the fore reef and reef wall (25 and 35 m). Like many species of scleractinian corals, M. cavernosa has an obligate symbiosis with dinoflagellate microalgae from the family Symbiodiniaceae. Here, we describe the Symbiodiniaceae taxa found within previously sampled and genotyped M. cavernosa populations along a depth gradient on the Belize Barrier Reef by implementing high-throughput sequencing of the ITS2 region of Symbiodiniaceae ribosomal DNA an...

Mangroves reduce the vulnerability of coral reef fisheries to habitat degradation
by Alice Rogers, Peter J. Mumby Despite general and wide-ranging negative effects of coral reef degradation on reef communities, hope might exist for reef-associated predators that use nursery habitats. When reef structural complexity is lost, refuge density declines and prey vulnerability increases. Here, we explore whether the presence of nursery habitats can promote high predator productivity on degraded reefs by mitigating the costs of increased vulnerability in early life, whilst allowing for the benefits of increased food availability in adulthood. We apply size-based ecosystem models of coral reefs with high and lo...

An ICP study and an ICR/MALDI study at high mass resolution of two ancient Maya greenstone artifacts from Pacbitun, Belize, and two decorative jade specimens.
Abstract Two Early Classic period (ca 250-600 CE) Maya carved, greenstone jade pendants, Specimens A and B, were recovered from the Pacbitun site in Belize in 1987. Novel highly-resolved polyatomic ions from jade grit have been observed using Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS), specifically using the Bruker Daltonics, SolariX XR mass spectrometer, combined with matrix-assisted laser desorption/ionization (MALDI); the matrix material was α-cyano-4-hydroxycinnamic acid. Mass scans of resolution ~600,000 were obtained for the jade pendants and two British Columbia jade orn...

Ancient Maya wetland fields revealed under tropical forest canopy from laser scanning and multiproxy evidence [Sustainability Science]
We report on a large area of ancient Maya wetland field systems in Belize, Central America, based on airborne lidar survey coupled with multiple proxies and radiocarbon dates that reveal ancient field uses and chronology. The lidar survey indicated four main areas of wetland complexes, including the Birds of Paradise... (Source: Proceedings of the National Academy of Sciences)

Warm bodies, cool wings: regional heterothermy in flying bats.
Abstract Many endothermic animals experience variable limb temperatures, even as they tightly regulate core temperature. The limbs are often cooler than the core at rest, but because the large locomotor muscles of the limbs produce heat during exercise, they are thought to operate at or above core temperature during activity. Bats, small-bodied flying mammals with greatly elongated forelimbs, possess wings with large surfaces lacking any insulating fur. We hypothesized that during flight the relatively small muscles that move the elbow and wrist operate below core body temperature because of elevated heat ...

The youngest meningioma? A historic Maya adolescent from Tipu, Belize
We present a hyperostotic cranial lesion in an adolescent from the early historic population of Tipu in west central Belize. It fits most clinical and epidemiological patterns of meningeal expression in modern children, and differential diagnosis finds other possible conditions, including dietary deficiencies and genetic anaemias, unlikely. The often subtle characteristics of meningiomas, which can be both osteolytic and osteoblastic, need to be described in detail to diffe rentiate them from other conditions, especially porotic hyperostosis. The Tipu case is the only nonadult example to correspond with published clinical ...
