Locating Nests of Birds in Grasslands From a Mobile Tower Blind
Locating nests of grassland passerines can be difficult, labor intensive, and disruptive to birds and vegetation. We developed a mobile tower blind for observing adult bird behavior and used it to locate nests in a western Montana grassland. We compared nest-search efficiency of behavioral observations from the tower versus the ground. Nests of savannah sparrow (Passerculus samhvichensis) were found in a higher proportion of territories searched from the tower (13/16 = 82%) than from the ground (4113 = 3 1%). Average search time for each nest found was lower from the tower (44 min) than from the ground (127 min). Both were lower than when we used drags made of rope or cable and chain (411 min). but nests were found earlier in the nesting cycle when we used drags. Adult birds were agitated and reluctant to approach and reveal their nests whenever an unconcealed observer was present in or near their territory. In contrast, normal behavior resumed within a few minutes after an observer entered the tower, even when the tower blind was within 10m of the nest. Observing behavioral cues from a tower blind provides substantial advantages for locating nests of savannah sparrows and probably other grassland birds. but effectiveness of the approach likely varies among species and habitats
Tick-, mosquito-, and rodent-borne parasite sampling designs for the National Ecological Observatory Network
Parasites and pathogens are increasingly recognized as significant drivers of ecological and evolutionary change in natural ecosystems. Concurrently, transmission of infectious agents among human, livestock, and wildlife populations represents a growing threat to veterinary and human health. In light of these trends and the scarcity of long-term time series data on infection rates among vectors and reservoirs, the National Ecological Observatory Network (NEON) will collect measurements and samples of a suite of tick-, mosquito-, and rodent-borne parasites through a continental-scale surveillance program. Here, we describe the sampling designs for these efforts, highlighting sampling priorities, field and analytical methods, and the data as well as archived samples to be made available to the research community. Insights generated by this sampling will advance current understanding of and ability to predict changes in infection and disease dynamics in novel, interdisciplinary, and collaborative ways

Tick-, Mosquito-, and Rodent-Borne Parasite Sampling Designs for the National Ecological Observatory Network [Special Feature: NEON Design]
Parasites and pathogens are increasingly recognized as significant drivers of ecological and evolutionary change in natural ecosystems.

Detached house
Předmětem bakalářské práce je návrh a vypracování studie a projektu pro provádění stavby pro rodinný dům s provozovnou v lokalitě Brno Mokrá Hora. Provozovnu tvoří výdejní místo pro online obchod. Budova sestává z polozapušťeného suterénu jednoho nadzemního podlaží. Bude sloužit jako trvalé bydlení pro čtyřčlennou rodinu a pracoviště pro dva zaměstnance. Stěny bude tvořit vápenopískové zdivo s kontaktním zateplovacím systémem ETICS, stropy budou železobetonové a střecha plochá vegetační. Součástí návrhu je také parkoviště pro dva osobní automobily a jedno lehké užitkové vozidlo. Zajímavost řešení spočívá ve výškové poloze střechy, nachází se totiž v úrovni místní komunikace. Projekt pro provádění stavby byl zpracován v programu AutoCAD, studie a vizualizace pomocí programů ArchiCAD a Artlantis 5.The subject of this bachelors thesis was to design a single-family house in Brno Mokrá Hora and process the study and the design documentation for this house. Part of it will serve as permanent housing for a 4 member family and the second part as a distribution point for an online shop with 2 employees. The walls will consist of sand-lime bricks with an additional contact thermal insulation system ETICS, the ceiling will be reinforced concrete constructions and the house will have a walkable flat green roof. Part of the documentation is also the modification design of the surrounding terrain and the design of the car park for 2 cars and 1 light commercial vehicle. An interesting design choice is the height level of the roof, which is situated in the same level as the local road. Design documentation was processed using the program AutoCAD, the study and the visualization using both ArchiCAD and Artlantis 5.
