Nestled among lush green vegetation of Buffalo Bayou Park, Waugh Drive Bridge rests over Buffalo Bayou, less than two miles west of Downtown Houston. The bat flights are amazing, winding along the bayou or through the skyscrapers across downtown. An estimated 250,000 Mexican free-tailed bats call the bridge home. The bat population fluctuates through the year, with the peak in the summer and early fall. A large population of bats continues to reside in the bridge through the winter months, resulting in awesome emergences on warm winter evenings. Upon emerging at sunset, the bats usually fly east along the bayou before dispersing. The best bat viewing locations are:the viewing platform at the southeast corner of the bayou bank, next to the bridge (along Allen Parkway);
the northeast bank of the bayou, near the bridge(near Memorial Drive); and
on the east rail sidewalk of the bridge itself, looking directly down into the bayou channel.
The best emergences happen on warm nights any month of the year. However, the bats usually remain inside the bridge crevices and do not emerge when sunset temperatures are near 50 degrees or below, or when it is raining. "Bat Chats" occur at the bridge on Friday nights from March through October. Please arrive 30 minutes before sunset to hear the battyQ & A presentation. Houston Area Bat Team members will be on-hand to answer questions about bats in general and about the Waugh Drive colony. Buffalo Bayou Partnership offers boat trips on the bayou, culminating in watching the bat flight from below.
Anopheles darlingi is the main malaria vector in the Amazon region and is among the most efficient malaria vectors worldwide. However, due to the lack of a well-established laboratory colony, key control-relevant aspects of the bionomics, behaviour, genetics, and vector-parasite relationships of An. darlingi remain unknown. Here, biological parameters that had been successful in initiating other Anopheles colonies were optimized and improved for An. darlingi, with the aim of establish a free-mating, stable, and highly productive laboratory colony.

This constitutes the first report of a free-mating, highly productive, and long-standing An. darlingi laboratory colony established through natural copulation induction, which will support critical malaria research. This rearing methodology may be a transferable, cost-effective alternative to labour-intensive forced mating practices widely used in maintaining other Anopheles colonies.
Herein it is reported the successful establishment of the first free-mating, highly productive, and long-lasting An. darlingi colony by: a) inducing natural copulation through a combination of optimal thermo-period and light stimulation; and b) optimizing egg oviposition and larval rearing parameters. Despite the relevance of An. darlingi for malaria transmission in the Amazonian region [10, 11], many aspects of its physiology, behavior, ecology, genetics, and interaction with Plasmodium spp. are poorly understood due to the lack of a laboratory colony that can serve as a source of large numbers of individuals [35, 36]. This large and highly productive colony is a unique, valuable resource for developing, and evaluating effective vector-based strategies against malaria transmission in the Amazon. Extensive methodological details are provided to the scientific community to encourage the reproduction of the results, establishment of additional colonies, and extrapolation of the described methods to critical Anopheles vectors in the Amazon and in other regions of the world.
The establishment of autonomous neotropical anopheline colonies under insectary conditions has had variable success. Some anopheline species are considered relatively easy to colonize, such as Anopheles albimanus that does not require copulation induction [38]. In contrast, An. pseudopunctipennis requires artificial induction of mating [22]. In addition, the number of generations needed to develop an autonomous colony also varies by species and population origin. For example, the Tapachula, and Abasolo Mexican laboratory strains of An. pseudopunctipennis required 5 and 12 generations to select a free-mating population, respectively [22]. A stenogamous colony of Anopheles albitarsis from Brazil was obtained in six generations [39] while free-mating in Anopheles aquasalis was recorded in the F2 generation [40]. Finally, the previously attempted Mexican An. darlingi colony collapsed at the F9 generation before becoming autonomous [14], yet the Peruvian An. darlingi colony became autonomous after nine generations. Therefore, it is suggested that free-mating in colonized An. darlingi can only be demonstrated after rearing at least nine generations.
Titanfall has three DLC packs available to it, each containing three maps ad several new achievements. At launch, these three map packs were available for purchase separately or in the Season Pass bundle - however, on March 11, 2015, the Season Pass and all accompanying DLC was made free for download in celebration of the game's first birthday.[1]
The second season opens after some time has passed, as Mother and Father have been salvaged by a mysterious group of settlers governed by a mysterious artificial intelligence simply known as The Trust. The colony has shifted to the Tropical Zone of the planet, with the flying serpent creature that Mother spawned in the first season finale on the loose. The season ends with a new android created by Father, known as Grandmother (Selina Jones), trapping Mother in a virtual reality prison, hellbent on continuing her ancient mission of devolving humanity.
For Windows, Mac, Linux. The game is distributed by DRM-free download. RimWorld is developed by Tynan Sylvester and Ludeon Studios, and we've been improving it since its first public release on November 4, 2013.
