“…During our experiment, the Tb2→Y sample (after four weeks of incubation) was lost, and hence the shift in Tb→Y samples cannot be determined accurately. Furthermore, transplant samples behaved differently in the two lakes, suggesting that the local environment influences the functional profile of a community, maybe due to the nutrient availability in that environment and how it differs from that of the original environment [53,54]. Although these shifts are not quantified, they support our hypothesis that the local environment influences the functional profile of the swapped bacterial community, as was previously reported in plants [14] and animals [59].…”

“…The 16S rRNA gene-based bacterial community composition of BG samples was significantly different between lakes (Additional file 1, Fig. S4A), which was expected, as the two lakes have different trophic states [53-55]. However, results from the functional profile analysis have unexpected implications for resolution dependency and the community function relationship.…”

“…Two proximity (21 km), sub-alpine lakes in northern Taiwan were chosen as experimental sites: Tsuei-Feng Lake (TFL) (24° 30’ 52.5’’, 121° 36’ 24.8’’ E) and Yuan-Yang Lake (YYL) (24° 34’ 33.6’’ N, 121° 24’ 7.2’’ E), at an altitude of 1,840 and 1,670 m, respectively. These lakes, despite being at similar altitudes and geographical locations, have different trophic states, with TFL being oligotrophic [53] and YYL mesotrophic [54]. Both lakes are within a protected area and are therefore introduced to minimal or no anthropogenic activity year-round.…”

9Microbial communities have long been assumed to have functional redundancy, but very few 2 0 studies have tested this empirically. Here, we performed a time series in situ reciprocal transplant 2 1 experiment in two lakes with disparate trophic states to empirically test for functional 2 2 redundancy. We determined that the two lakes had different community compositions, and these 2 3 did not change even after incubating in a different environment. However, functional attributes 2 4were different between read-and predicted gene-level analyses of the communities, highlighting 2 5 the importance of resolution when delineating community functional relationships. Furthermore, 2 6there was a linear relationship between community composition and functional attributes, with a 2 7 broad range of similarities in the former and a narrower range and overall more similarity in the 2 8 latter, providing support for partial functional redundancy. Ecoplate analysis suggests that the 2 9 total metabolic activity of a community is influenced by its local environment, even though 3 0 broad functions like carbon metabolism are widespread. Together, our results support the 3 1 presence of resolution-dependent partial functional redundancy in aquatic environments. 3 2

Airborne microorganisms, especially those at high altitude, are exposed to hostile conditions, including ultraviolet (UV) radiation, desiccation, and low temperatures. This study was conducted to compare the composition and abundance of airborne microorganisms at a high-altitude site, Mt. Jodo [2,839 m above mean sea level (AMSL)] and a suburban site (23 m AMSL) in Toyama, Japan. To our knowledge, this is the first study to investigate microbial communities in air samples collected simultaneously at two sites in relatively close proximity, from low and high altitude. Air samples were collected over a period of 3 years during 2009–2011. We then examined the bacterial and eukaryotic communities and estimated the abundance of bacteria and fungi with real-time TaqMan PCR. The airborne bacterial and eukaryotic communities differed between high-altitude and suburban sites on each sampling day. Backward trajectory analysis of air masses that arrived at high-altitude and suburban sites on each sampling day displayed almost the same paths. The bacterial communities were dominated by Actinobacteria, Firmicutes, and Proteobacteria, while the eukaryotic communities included Ascomycota, Basidiomycota, and Streptophyta. We also predicted some application of such microbial communities. The airborne bacterial and fungal abundance at the high-altitude site was about two times lower than that at the suburban site. These results showed that each airborne microbial communities have locality even if they are collected close location.

“…Microorganisms are both the producers and decomposers of organic matter in aquatic ecosystems and play an important role in regulating the circulation of biogenic elements such as carbon, nitrogen, phosphorus, and sulfur in lakes [1,2]. Bacteria, as an important part of the microbial community, are mainly responsible for the mineralization and recycling of organic matter, while the recycling of dissolved organic carbon (DOC) in lakes is mainly fulfilled by heterotrophic bacteria [3][4][5]. Phytoplankton are the primary producers at the basis of aquatic food webs and can quickly respond to environmental changes [6].…”

Phytoplankton are the primary producers at the basis of aquatic food webs, and bacteria play an important role in energy flow and biochemical cycling in aquatic ecosystems. In this study, both the bacterial and phytoplankton communities were examined in the oligotrophic Lake Basomtso and the eutrophic Lake South (China). The results of this study showed that the phytoplankton density and diversity in the eutrophic lake were higher than those in the oligotrophic lake. Furthermore, Chlorophyta (68%) and Cryptophyta (24%) were the dominant groups in the eutrophic lake, while Bacillariophyta (95%) dominated in the oligotrophic lake. The bacterial communities in the waters and sediments of the two lakes were mainly composed of Proteobacteria (mean of 32%), Actinobacteria (mean of 25%), Bacteroidetes (mean of 12%), and Chloroflexi (mean of 6%). Comparative analysis showed that the abundance of bacteria in the eutrophic lake was higher than that in the oligotrophic lake (p < 0.05), but the bacterial diversity in the oligotrophic lake was higher than that in the eutrophic lake (p < 0.05). Finally, the bacterial abundance and diversity in the sediments of the two lakes were higher than those in the water samples (p < 0.05), and the Latescibacteria and Nitrospinae groups were identified only in the sediments. These results suggest that both the phytoplankton and bacterial communities differed considerably between the oligotrophic lake and the eutrophic lake.
