CNCP instituted, among other things, an ‘‘economic incentive payment’’ of $4.00 per delivered nutria tail from registered participants in the program. To examine whether this bounty has had an impact on nutria harvest and whether alternative bounty levels can, in general, generate additional harvesting activities, we developed a bioeconomic supply model that relates Louisiana’s annual nutria harvests to a suite of economic and environmental factors. Results suggested that the annual nutria harvest is responsive to both the price received per animal and costs. Results also suggested that the nutria... |

| Neste estudo, utilizaram-se 30 nutrias, 15 fêmeas e 15 machos, com o sistema arterial aórtico-abdominal preenchido com látex 603, pigmentado em vermelho, e fixado em uma solução aquosa de formaldeído a 20%. A aorta abdominal emitiu de sua superfície dorsal de 6 a 8 artérias lombares únicas. Das artérias renais, direita e esquerda, originaram-se as artérias frênico-abdominal para irrigar parte do diafragma e da parede abdominal lateral cranial. A aorta abdominal lançou dorsalmente, a artéria sacral mediana, cranialmente a sua bifurcação em artérias ilíacas comuns. As artérias ilíacas comuns, ramos terminais da aorta abdominal, originaram as artérias ilíacas interna e externa. A artéria ilíaca interna distribuiu-se nas vísceras da cavidade pélvica. A artéria... |
