Soil fertility evaluation and land-use effects on soil properties, carbon and nitrogen sequestration in the rainforest of Nigeria by Ugochukwu Nnamdi Onyegbule, Stanley Uchenna Onwudike, Nkechinyere Opara-Nadi, Olive Opara-Nadi

“…This study investigates changes in soil properties, specifically soil organic carbon (SOC) and total nitrogen (TN), associated with different land use systems derived from forests in the rainforest zone of Nigeria. The land use systems examined include mature oil palm plantation (OP), bush fallow or secondary forest (BF), alley cropping with multi-purpose trees (AC), and continuous cassava cropping with and without fertilizer (FC and UC). …”

Methylmercury content in soil and litter from the Amazonian rainforest and its potential fate during forest fires by Anne Helene Fostier, David Amouroux, Emmanuel Tessier, José Lucas Martins Viana, Larissa Richter

“…Methylmercury in soils and vegetation from the Amazonian rainforest is still poorly studied. Hence, the aim of this work was to determine the total mercury [THg] and methylmercury [MeHg] concentrations in litter and surface soil, MeHg deposition via litterfall, and the MeHg fate during a forest fire in the Amazonian rainforest. …”

A Fish-Based Index of Biotic Integrity for Neotropical Rainforest Sandy Soil Streams—Southern Brazil by Gabriel Gonino, Evanilde Benedito, Vivian de Mello Cionek, Maria Teresa Ferreira, João Manuel Oliveira

“…This study aimed to develop a fish-based Index of Biotic Integrity (N3S-IBI) in an agricultural region within the domains of the Atlantic rainforest in Brazil. We sampled 23 first-order streams and used large-scale land use and a local physical condition index to choose reference sites and to classify sites according to the disturbance level. …”

Whole genome sequencing unravels cryptic circulation of divergent dengue virus lineages in the rainforest region of Nigeria by Bernard Anyebe Onoja, Judith Uche Oguzie, Uwem Etop George, Kaego Emmanuel Asoh, Philip Ajayi, Toluwanimi Faithful Omofaye, Imafidon Oluwatoyin Igeleke, Philomena Eromon, Soumare Harouna, Edyth Parker, Adekunle Johnson Adeniji, Christian T. Happi

“…In this study, we investigated the epidemiology and genetic diversity of dengue in the rainforest region of Nigeria. We screened 515 febrile patients who tested negative for malaria and typhoid fever in three hospitals in Oyo and Ekiti States in southern Nigeria with a combination of anti-dengue IgG/IgM/NS1 rapid test kits and metagenomic sequencing. …”

Landscape heterogeneity drives spatial distribution of palm community in a Neotropical rainforest reserve affected by defaunation by Katia V. Miranda-Gallegos, Armando Navarrete-Segueda, Jorge Cortés-Flores, M. Lourdes González-Arqueros, Estefanía E. Acosta-Pérez, Guillermo Ibarra-Manríquez

“…Background: Our study presents the first assessment of the relationships between environmental heterogeneity and the palm community at the landscape scale at the northern boundary of tropical rainforest distribution in America. Question: How does landscape-level heterogeneity (edaphic, topographic as well as the density, diversity, and tree biomass) shapes the palm community in a protected reserve affected by defaunation? …”

Spatial heterogeneity and influence mechanisms on soil respiration in an old-growth tropical montane rainforest with complex terrain by Huai Yang, Huai Yang, Ting Huang, Yide Li, Yide Li, Wenjie Liu, Jialin Fu, Biao Huang, Qiu Yang

“…IntroductionAlthough numerous studies have investigated ecosystem-scale soil respiration (SR) at different ecosystem, our understanding of spatial heterogeneity of SR at plot scale is still incomplete, especially in tropical rainforests with complex topography. Further, the ecological factors that drive the variability of SR in tropical rainforests is also poorly understood.MethodsHere, we investigated the spatial variations and control mechanisms of SR in a 60-ha plot of old-growth tropical rainforest with complex topography. …”
