Subspecies and Distribution. P. g. gymnocercus Fischer, 1814 — subtropical grasslands of NE Argentina, SE Brazil, Paraguay, and Uruguay. P.g. antiquus Ameghino, 1889 — Pampas grasslands, monte scrublands, and open woodlands of C Argentina. P. g. lordi Massoia, 1982 — Chaco-montane tropical forest ecotone in NW Argentina (Salta & Jujuy Provinces). The subspecific status of the Pampas Fox from Entre Rios Province in Argentina remains unclear, and there are no data regarding the taxonomic position of Bolivian foxes. in Canidae

Distribution. NE Brazil, at E border of semiarid Caatinga ecoregion ("sertao") and Caatinga—Atlantic Forest ecotone ("agreste") of Alagoas, Sergipe, and Bahia states. Previous records outside this area could be misidentifications. in Phyllostomidae

Distribution. Brazilian Amazon, S of the Rio Amazonas, between the Tapajos/Juruena system and the Tocantins/Araguaia river system to the E, in the Brazilian states of Para and Mato Grosso; the exact S limit ofits distribution is unclear, but it seems likely that it coincides with the transition between the Amazon rainforest and the cerrado savannas of C Brazil; this ecotone encompasses headwaters of the Xingu and Tapajos river systems in N Mato Grosso. Vieira's Titi (C. vieirai) is also known to occur in this region, but there are too few records to confirm whether their distributions intergrade, or in fact where the exact limits of their distributions are. One recent study also found that the Red-bellied Titi may be absent from or present at extremely low densities in large areas of the Tocantins-Xingu interfluvium. Given the overall lack of records, while it is clear that the Red-bellied Titi occurs over a vast area of the SE Amazon Basin, the exact limits of its distribution within this area remain unclear. in Phitheciidae

Does lake eutrophication support biological invasions in rivers? A study on Dreissena polymorpha (Bivalvia) in lake-river ecotones
<p>The zebra mussel (Dreissena polymorpha) has all traits required to effectively colonize the aquatic environment and consequently reduce the diversity of native bivalves We hypothesized that the zebra mussel chooses lake outlets characterized by medium current velocity and good food conditions. Here, we analyzed differences between bivalve abundances in lake outlets with varying environmental conditions such as the Carlson Index (trophy status), depth, width, current velocity, bed vegetation coverage, and type of bottom substrate. The results showed that the zebra mussel inhabits outlets that provide food (high trophy outlets) and have a mineral bed and a medium current velocity (ca. 0.2–0.3 m s-1). The following main factors seem to be favorable for colonizing such outlets: (1) easy access to high amounts of food due to the increased density of the suspension drifting from the lake and (2) easy transport of the zebra mussel larvae from the lake to the downstream. The zebra mussel larvae drifting with the current may colonize the downstream. An increase in lake trophy may indirectly cause an increase in biological invasions in rivers.</p>
