Ecological Impact of Epigeal Termitaria on Vertebrates in the Tsavo Region of Southeast Kenya
Termites ecologically engineer their environment by producing termitaria (mounds) used by many other species as dens, lookouts or food sources. The role of termite mounds in biological communities is relatively unknown, despite their ubiquitous nature. I investigated their impact on vertebrates in …

Epigeal invertebrates of Yorkshire allotments: the influence of urban-rural gradient and management style
… similarities in habitat use.Pitfall trapping for epigeal invertebrates on forty-two plots found a trend of increasing abundance from rural to urban plots, with beetles, woodlice and spiders constituting 79% of the catch. Diversity was highest on one suburban site, but lowest on another.When the …

The edge effects of mango farming on flower visitor insect communities and epigeal ant species in Northern-Eastern South Africa
This study investigates issues of gender inequality at the workplace within the Department of Education in Thulamela municipality, Vhembe district. Gender inequality is a persisting problem that hinders equal participation of males and females both economically and politically. The study further …

The effect of native forest dynamics upon the arrangements of species in oak forests-analysis of heterogeneity effects at the example of epigeal arthropods
The heterogeneity in species assemblages of epigeal spiders was studied in a natural forest and in a managed forest. Additionally the effects of small-scale microhabitat heterogeneity of managed and unmanaged forests were determined by analysing the spider assemblages of three different …

Ground - dwelling arthropods in a biosphere reserve: patterns of diversity and conservation implications
… of magnitude larger than usual (30 000 km2), of epigeal spider, beetle and millipede diversity in the Vhembe Biosphere Reserve – the largest biosphere reserve in South Africa, and one of the largest in Africa. Firstly we aim to provide an evaluation of the ability of a range of broad and fine …

The embryology of Prionium serratum (L.f.) Drege ex E.Mey. (Juncaceae:Cyperales) and its implications for the phylogeny of Cyperales
… is formed from both integuments. Germination is epigeal and the seedlings are of Type A. Phylogenetic analyses using morphological data (including embryology) and total evidence (rbcL sequence data combined with morphological data) revealed that Juncaceae are paraphyletic with Prionium basal to …

Interactive Effects of Cover Crops, Invertebrate Communities and Soil Health in Corn Production Systems
… Regenerative systems also hosted more robust epigeal and soil invertebrate communities, which were correlated with fewer pests. Regenerative systems had generally healthier soil and soil community characteristics; soil health in cornfields was positively correlated with invertebrate abundance …

The importance of cotyledon functional morphology and patterns of seed reserve utilization for the physiological ecology of neotropical tree seedlings
… forest on Barro Colorado Island, Panama. Among epigeal phanerocotylar species, photosynthetic capacity per unit cotyledon mass is linearly related to the reciprocal of cotyledon thickness. The relative balance of the dual functions of cotyledons, export of seed reserves vs. photosynthesis, can …

NATURAL REGENERATION DYNAMICS AND SURVIVAL INFLUENCED BY ABIOTIC AND BIOTIC FACTORS IN A BOTTOMLAND HARDWOOD FOREST
… survival rates among native-hypogeal, native-epigeal, and invasive-Chinese tallow differed; Chinese tallow had a significantly lower survival rate than the native groups, likely as a result of weather events. Height and diameter increased the odds of survival for all regeneration groups. …

INNOVATIVE APPROACHES TO PLANT PROTECTION AND PRODUCE SAFETY THROUGH HIGH-PRECISION PLANT MANAGEMENT SYSTEMS
… vigor of lettuce, increasing both root and epigeal biomass. Root imaging and analysis using MATLAB confirmed the promotion of root system development, and a better wellness of plants grown in soils treated with those isolates. MinION sequencing revealed a dominance of Pseudomonadota, …

Ground-Dwelling Arthropod Community Structure of Saskatchewan's Agroecosystems and Seeded Grasslands
Ground-dwelling arthropods hold a critical role in maintaining the health and function of agroecosystems in the Canadian prairie landscape. However, the distribution of many groups is often limited to non-crop habitats, such as roadside ditches or distantly spaced grassland refuges. The high …
