TL;DR: In the field of participatory modeling, the implicit and explicit knowledge of stakeholders to create formalized and shared representations of reality has evolved into a field of study as well as a practice.
Abstract: Participatory modeling engages the implicit and explicit knowledge of stakeholders to create formalized and shared representations of reality and has evolved into a field of study as well as a practice. Participatory modeling researchers and practitioners who focus specifically on environmental resources met at the National Socio-Environmental Synthesis Center (SESYNC) in Annapolis, Maryland, over the course of 2 years to discuss the state of the field and future directions for participatory modeling. What follows is a description of 12 overarching groups of questions that could guide future inquiry.

TL;DR: Toxicity experiments performed in mice suggest that, at low venom doses, neurotoxicity leading to respiratory paralysis represents the predominant mechanism of prey immobilization and death, but at high doses, such as those injected in natural bites, intravascular thrombosis due to the action of the prothrombin activator may constitute a potent and very rapid mechanism for killing prey.

TL;DR: An inventory of the understory and canopy of 4 ha of lower montane cloud forest at Monteverde, Costa Rica, yielded 190 bryophyte species: 133 hepatics, 56 mosses and 1 homwort, which appeared that the percentage of Bryophytes restricted to the canopy may be the same in lowland and montane rain forests.
Abstract: An inventory of the understory and canopy of 4 ha oflower montane cloud forest at Monteverde, Costa Rica, yielded 190 bryophyte species: 133 hepatics, 56 mosses and 1 homwort. Thick branches of the lower canopy were by far the richest habitat in terms of number of species (99), trunks from 1m upwards had 65 species, lianas, shrubs, saplings, or living leaves in the understory had about 36-46 species each, and 16 species were found on rotten logs. The figures are illustrative of the great diversification of microhabitats of bryophytes in a tropical montane cloud forest. About 36% ofthe species, including more than half ofthe corticolous ones, occurred exclusively in the canopy. It appeared thatthe percentage ofbryophyte species restricted to the canopy may be the same in lowland and montane rain forests, in spite of the great differences in species abundance and composition in the two kinds of forest.

TL;DR: Despite the fact that jararhagin is complexed by plasma proteins after iv injection, its hemorrhagic activity was not inhibited by the plasma proteinase inhibitor alpha(2)-macroglobulin, and was only partially reduced by normal mouse serum, suggesting that resistance to inhibition may contribute to its ability to cause pulmonary hemorrhage.

TL;DR: This is the first report of a successful isolation in cell culture of R. amblyommii and R. felis from Central America.
Abstract: During 2010, 15 adult ticks, identified as Amblyomma cajennense, were collected from horses in Cahuita and Turrialba districts, whereas 7 fleas, identified as Ctenocephalides felis, were collected from a dog in San Jose city, Costa Rica. In the laboratory, three A. cajennense specimens, two from Cahuita and one from Turrialba, were individually processed for rickettsial isolation in cell culture, as was a pool of seven fleas. Rickettsiae were successfully isolated and established in Vero cell culture from the three ticks and from a pool of seven fleas in C6/36 cell culture. The three tick isolates were genotypically identified as Rickettsia amblyommii, and the flea isolate was identified as Rickettsia felis through DNA sequencing of portions of the rickettsial genes gltA, ompA, and ompB of each isolate. In addition, other seven ticks were shown to contain rickettsial DNA. Polymerase chain reaction products of at least two of these ticks were sequenced and also showed to correspond to R. amblyommi...
