| ABSTRACT Daspletosaurus is a Campanian genus of Tyrannosauridae from North America. This genus occupied the same geographic area of Albertosaurus, but remains of Albertosaurus are more abundant than Daspletosaurus. Here is described a subadult maxilla (AMNH FARB 5477) of Daspletosaurus sp. from Montana (USA) and possibly from the Two Medicine Formation. The description is based on Carr (1999) that described cranial ontogenetic variations in tyrannosaurids. The maxilla belongs to the ontogenetic Stage 3 sensu Carr (1999), in which the maxilla is thick, the lateral surface of the bone well sculptured, and the maxillary fenestra is subcircular and well separated from the anterior edge of antorbital fossa. Possibly there were more than one species of... |

| O levantamento de epífitas vasculares foi realizado na porção norte da Serra da Prata (48º 41' 59,39" O e 25º 36' 46,39" S), município de Morretes, abrangendo 6,3 ha de encosta situada entre 400 e 1.100 m s.n.m., coberta por Floresta Ombrófila Densa Submontana e Montana. Os objetivos do trabalho foram: 1) caracterizar a flora epifítica vascular; 2) discutir sua distribuição altitudinal e nas categorias ecológicas; 3) avaliar a similaridade florística com outras áreas do sul e sudeste do Brasil. O levantamento foi efetivado entre 2005 e 2010. Cento e vinte forófitos, distribuídos por quatro altitudes (400, 600, 800 e 1.000 m), foram escalados e detalhadamente vasculhados. Foram registradas 278 espécies, 109 gêneros e 30 famílias de epífitas vasculares.... |

| Agricultural industries in small geographical areas with limited acreage tend to be overlooked by those not associated with the growing region or industry. Sugarbeets continue to be produced in a relatively small geographic area and on relatively limited acreage in Minnesota, North Dakota, and eastern Montana. These factors, along with continued debate over policies affecting domestic sugar industries and recent industry expansions, help justify a continued assessment of the economic importance of the sugarbeet industry to the regional economy. Revenues from sugarbeet production and expenditures by processors to Minnesota, North Dakota, and Montana entities in fiscal 2003 represented the direct economic impacts from the industry. Expenditure... |

| The economic impact of three invasive, exotic weeds--diffuse, spotted, and Russian knapweed (Centaurea diffusa, C. maculosa, and Acroptilon repens)--on Montana's economy was estimated using a procedure developed for another invasive weed species. Published data and that from a survey of county weed boards were used to estimate direct negative impacts of over $14 million annually due to infestation of over 2 million acres of rangeland and wildland. This amounts to about $10.63 on each infested grazing land acre and $3.95 on each infested wildland acre. Direct plus secondary economic impacts, estimated using an input-output model, are about $42 million annually, which could support over 500 jobs in the state's economy. This first approximation suggests... |
