Abstract Background The effects of climate on plant species ranges are well appreciated, but the effects of other processes, such as fire, on plant species distribution are less well understood. We used a dataset of 561 plots 0.1 ha in size located throughout Yosemite National Park, in the Sierra Nevada of California, USA, to determine the joint effects of fire and climate on woody plant species. We analyzed the effect of climate (annual actual evapotranspiration [AET], climatic water deficit [Deficit]) and fire characteristics (occurrence [BURN] for all plots, fire return interval departure [FRID] for unburned plots, and severity of the most severe fire [dNBR]) on the distribution of woody plant species. Results Of 43 species that were present on at least two plots, 38 species occurred on five or more plots. Of those 38 species, models for the distribution of 13 species (34%) were significantly improved by including the variable for fire occurrence (BURN). Models for the distribution of 10 species (26%) were significantly improved by including FRID, and two species (5%) were improved by including dNBR. Species for which distribution models were improved by inclusion of fire variables included some of the most areally extensive woody plants. Species and ecological zones were aligned along an AET-Deficit gradient from cool and moist to hot and dry conditions. Conclusions In fire-frequent ecosystems, such as those in most of western North America, species distribution models were improved by including variables related to fire. Models for changing species distributions would also be improved by considering potential changes to the fire regime.

Rains in the Mojave Desert region are intense and result in the destruction of property. This destruction is significant and affects development plans in the area. Joshua Tree National Park (JTNP) is one of the areas affected as a result of flash floods in the Mojave Desert region. As part of the efforts to minimize the effects caused by flash floods in the park, there was a need to carry out a hydrological analysis of surface runoff in order to map out high risk areas that are susceptible to floods after Monsoonal rains, identify areas in the park that require diversion berms, and establish the effectiveness of the existing diversion berms. The analysis result was a 3D topographic model and a map that contains high flood risk areas and potential areas where diversion berms may be constructed to divert surface runoff and protect the park’s infrastructure.

Rhagomys longilingua is one of the rarest sigmodontine rodents of South America, currently known from only 2 localities (4 individuals) in Peru and Bolivia. Here we report 3 additional localities in Peru, one of which extends the geographic distribution range of this species 613 km northeast from the type locality (Suecia, Manu National Park, Cusco department). Potential distribution models showed the presence of R. longilingua from Bolivia until Colombia along the eastern slope of the Andes.
