“…Because pH was only measured during one harvest at each site, it was not included in this analysis. Mass remaining data were log logit‐transformed to meet statistical assumptions (Power, Sokal, Rohlf, Rohlf, & Sokal, 1970; Warton & Hui, 2011). To evaluate the significance of linear mixed‐effects models the Kenward–Roger approximation was used to estimate F statistics and denominator degrees of freedom (Halekoh & Højsgaard, 2014).…”

Substrate quality drives fungal necromass decay and decomposer community structure under contrasting vegetation types

et al. 2020

Fungal mycelium is increasingly recognized as a central component of soil biogeochemical cycling, yet our current understanding of the ecological controls on fungal necromass decomposition is limited to single sites and vegetation types. By deploying common fungal necromass substrates in a temperate oak savanna and hardwood forest in the midwestern USA, we assessed the generality of the rate at which high‐ and low‐quality fungal necromass decomposes; further, we investigated how the decomposer ‘necrobiome’ varies both across and within sites under vegetation types dominated by either arbuscular or ectomycorrhizal plants. The effects of necromass quality on decay rate were robust to site and vegetation type differences, with high‐quality fungal necromass decomposing, on average, 2.5 times faster during the initial stages of decay. Across vegetation types, bacterial and fungal communities present on decaying necromass differed from bulk soil microbial communities and were influenced by necromass quality. Moulds, yeasts and copiotrophic bacteria consistently dominated the necrobiome of high‐quality fungal substrates. Synthesis. We show that regardless of differences in decay environments, high‐quality fungal substrates decompose faster and support different types of decomposer micro‐organisms when compared with low‐quality fungal tissues. These findings help to refine our theoretical understanding of the dominant factors affecting fast cycling components of soil organic matter and the microbial communities associated with rapid decay.

“…To confirm infection status and test for differences in level of infection between diets for each Nosema species, we used the following model: Nosema gene expression ~ diet*infection. We applied the nonparametric Scheirer-Ray-Hare test with the type-II sum of squares approach and the Dunn's post hoc test (P-values adjusted using the Benjamini-Hochberg method; Sokal & Rohlf, 1995). Subsequently, we pooled data from the two Nosema species (excluding uninfected cases) to test for differences between species and diets.…”

“…We used the type‐II sum‐of‐squares approach for unbalanced designs to calculate the test statistic (H) and its P‐value. Subsequently, to test for significant differences in gene expression between treatments, we used a Dunn's post hoc test and the Benjamini‐Hochberg method to adjust P‐values for multiple comparisons (Sokal & Rohlf, 1995).…”

Floral diversity allows honey bees, Apis mellifera L. (including its hybrids between subspecies) (Hymenoptera: Apidae), to meet their nutritional requirements. However, infection by Nosema spp. (Microsporidia: Nosematidae) destroys a bee's digestive epithelium, hindering the ability to absorb nutrients. In some subtropical regions, such as the Yucatan Peninsula, Mexico, nosemosis is one of the most widespread diseases in commercial apiaries. To date, there have been no reports of colony deaths attributable to the disease. It is possible that the naturally occurring diet in the Yucatan Peninsula sustains honey bee health. We tested this hypothesis by evaluating the effect of four diets -bee bread collected in the Yucatan's rainy and dry seasons, sucrose syrup, and a pollen substitute -on the response of caged Africanized honey bees (A. m. scutellata × A. m. adansonii × A. mellifera) to nosemosis infection (treatment with spores of Nosema apis Zander and Nosema ceranae Fries). We found that infected and uninfected bees consumed food in similar amounts regardless of the diet, although, overall, they fed at significantly lower rates when provided the pollen-substitute diet. Bees fed either of the bee bread diets had relatively low fat-body weight and expression of Vg, proPO, and GOx genes, three genes related to immune function. Bees fed sucrose syrup had low fat-body weight but relatively high gene expression. Infection from Nosema spores only reduced the individual survival probability for bees fed the bee bread collected in the dry season, yet bees fed the dry-season bee bread had the lowest infection rates. Our results indicate that natural stored bee bread in honey bee colonies from the Yucatan Peninsula could be one of the main factors influencing their survival and reducing Nosema spp. spore load.

There is a dearth of data about public health in the regular evaluation of heavy metal levels in seafood obtained from public market. This study aimed to examine the levels of essential (copper, zinc) and nonessential metals (cadmium, lead) in the tissues of cultured seabream (Sparus aurata), which was in public market. For this purpose, seabream samples were collected from the public market. And then, copper (Cu), zinc (Zn), cadmium (Cd), and lead (Pb) metal accumulation levels in tissues of the dissected gill, liver, kidney, and muscle were obtained by inductively coupled plasma mass spectrometry (ICP-MS). In order to understand whether the fish posed a risk to public health, risk evaluation formulations (estimated daily intake: EDI, hazard coefficients: HQ, hazard index: HI) were calculated for the muscle tissue. The data showed that Zn, Cd and Pb concentrations were maximal in the kidney tissue of S. aurata and Cu concentration were in the liver tissue, while the minimum heavy metal levels were in the muscle tissue. As a result, the maximum levels of heavy metals in the edible tissue of seabream were found as 0.11 mg Cu/kg wet weight, 0.72 mg Zn/kg wet weight, 0.12 mg Cd/kg wet weight, and 0.34 mg Pb/kg wet weight. Maximum values of them do not indicate any health risks as they are lower than the allowable tolerable levels specified by the international EDI estimation committees. The examined HQ and HI indicators were observed below 1 in all seasons. However, it is always possible for heavy metal intake to pose potential risks. For this reason, it is essential that the results of the study be interpreted from different perspectives and taken into consideration by other scientists.
