Microbial community structure varies across soil organic matter aggregate pools during tropical land cover change

Abstract: Soil microorganisms regulate multiple input and loss pathways of soil carbon (C); hence, changes in microbial communities are expected to affect soil organic matter (SOM) cycling and storage. Despite this, very little is known about how microbes respond to changes in soil structure and vegetation with land use and land cover change. This study aimed to identify relationships between microbial community composition and the distribution of SOM among soil aggregate fractions to answer the following research questions: (1) Are different microbial groups associated with different SOM pools? and (2) How do these relationships differ with changes in vegetation during tropical forest succession? We measured microbial composition via phospholipid fatty acid (PLFA) analysis and C and nitrogen (N) concentrations on physically separated aggregate fractions of soils from pastures, secondary forests (40 and 90 years old) naturally regrowing on abandoned pastures, and reference or primary forests in Puerto Rico. We found different microbial communities associated with different soil aggregate fractions. Fungal to bacterial ratios decreased and gram-positive to gram-negative bacterial ratios increased with decreasing physical fraction size (from the macroaggregates to the silt and clay fractions). Microbial composition also varied with land cover type and forest successional stage, with consistent trends among soil fractions. These results show that the soil matrix and soil microsite properties play an important role in the spatial distribution of fungal and bacterial-dominated communities. The similarities in land cover effects on microbial communities at different spatial scales suggest similar controls may be influencing microbial composition with potential implications for SOM storage and turnover. In addition, the majority of C and N (relative to total soil C and fraction mass) was isolated in the macroaggregate-occluded silt and clay-sized fractions, suggesting that association with mineral surfaces, and not occlusion of particulate organic matter within aggregates, is the dominant stabilization mechanism for SOM in these highly-weathered, fine-textured soils. These results highlight the importance of soil aggregation in C storage but through mechanisms different than those reported for temperate grassland soils.

The impact of customer contact on environmental initiatives for service firms

Abstract: The impact of business operations on the natural environment has been a public concern for decades and a research concern for years. To date, the focus of environmental impact research has been almost exclusively on manufacturing industries. Environmental research specific to service industries have been neglected, despite the fact that economies of developed nations are mostly made up of service businesses. This paper explores potential distinctions of service businesses as they may influence management motivation for taking environmentally friendly actions. Through a number of case studies, we observe some commonality of environmental motivations between service and manufacturing industries, as well as some environmental themes unique to services. These themes pertain to customer awareness of environmental initiatives of service firms by virtue of their involvement in the production process. Interestingly, customer involvement can have an adverse affect on environmental initiatives.

Palaeontological evidence for an Oligocene divergence between Old World monkeys and apes

Abstract: Molecular evidence suggests that the evolutionary split between hominoids and cercopithecoids occurred between 25 and 30 Myr ago, but fossil evidence for crown-group catarrhines (cercopithecoids and hominoids) before 20 Myr ago has been lacking; newly described fossils of a stem hominoid and a stem cercopithecoid precisely dated to 25.2 Myr ago help to fill this gap in the fossil record. Molecular evidence suggests that the evolutionary split between hominoids (apes and humans) and cercopithecoids (Old World monkeys) occurred between 25 million and 30 million years ago, but fossil evidence for the catarrhines (cercopithecoids and hominoids) only goes back some 20 million years. Nancy Stevens and colleagues go some way to filling this gap with the discovery of the earliest known evidence of both Old World monkeys and apes. The fossils, of a stem hominoid and a stem-cercopithecoid, were found in a stratum in the East African Rift of Tanzania precisely dated to 25.2 million years. This date, well back in the Oligocene epoch, adds greatly to the time in which both groups are known to have existed. Apes and Old World monkeys are prominent components of modern African and Asian ecosystems, yet the earliest phases of their evolutionary history have remained largely undocumented1. The absence of crown catarrhine fossils older than ∼20 million years (Myr) has stood in stark contrast to molecular divergence estimates of ∼25–30 Myr for the split between Cercopithecoidea (Old World monkeys) and Hominoidea (apes), implying long ghost lineages for both clades2,3,4. Here we describe the oldest known fossil ‘ape’, represented by a partial mandible preserving dental features that place it with ‘nyanzapithecine’ stem hominoids. Additionally, we report the oldest stem member of the Old World monkey clade, represented by a lower third molar. Both specimens were recovered from a precisely dated 25.2-Myr-old stratum in the Rukwa Rift, a segment of the western branch of the East African Rift in Tanzania. These finds extend the fossil record of apes and Old World monkeys well into the Oligocene epoch of Africa, suggesting a possible link between diversification of crown catarrhines and changes in the African landscape brought about by previously unrecognized tectonic activity5 in the East African rift system.
