The invasive Asian earthworms, Amynthas tokioensis and A. agrestis , have been successful in entering North American forests recent decades, with significant damage to both soils above-ground environments. This success could be driven part by a polyploid genetic system parthenogenetic reproduction, often suggested as benefits for species. Therefore, we assessed the population structure, diversity, reproductive of species using morphological traits panels microsatellite markers. A total 216 196 from six sites Vermont USA were analyzed. Although all worms morphologically hermaphroditic, lacked male pore (the structure allowing pass sperm between individuals), only 19% possessed pore. All earthworms triploid (scored three alleles at least 1 locus, usually several), was mix diploid individuals. Notable high proportion (80%) that one site.

Abstract Background In most regions and ecosystems, soils are the largest terrestrial carbon pool. Their potential vulnerability to climate land use change, management, other drivers, along with soils’ ability mitigate change through sequestration, makes them important balance management. To date, studies of soil management have been based at either large or site-specific scales, resulting in broad generalizations narrow conclusions, respectively. Advancing science practice requires scientific progress intermediate scales. Here, we conducted fifth a series ecoregional assessments effects forest on stocks, this time addressing Northeast U.S. We used synthesis approaches including (1) meta-analysis published literature, (2) survey (3) national inventory databases examine overall underlying drivers deforestation, reforestation, harvesting stocks. The three complementary data sources allowed us quantify direction, magnitude, uncertainty trends. Results Our findings revealed regionally consistent declines stocks due whether for agriculture urban development. Conversely, reforestation led significant increases C variation specific geographic factors. Forest showed no effect regardless place-based practice-specific Observational generally supported meta-analytic harvest trends, provided broader context by revealing factors that act as baseline controls ecoregion carbon-dense soils. These include range physical, parent material, topographic controls, also playing role.

After one year of surveying semiaquatic earthworms (Oligochaeta, Sparganophilidae), we describe Sparganophilus jenkinsi sp. nov., S. carveri oconeeae williamsae muskogee youngae and borgesae nov. based on extensive differences in morphological characters molecular data. Three additional species are described morphologically but not formally named due to limited material. The here can be organized into three groups: (1) jenkinsi, oconeeae, muskogee, carveri, williamsae, youngae, borgesae, sp02 have continuous tubercula pubertatis the region xvii-xxii, tubular nephridial bladder; (2) sp09 discrete pairs sack-like (3) sp10 posteriorly displaced reduced two segments, a "caecum."

Earthworms can act as ecosystem engineers by altering soil structure, which impacts other organisms and functioning. Jumping worms (family Megascolecidae) originating in Asia have been spreading North America, extending their northern range limits to Ontario, Canada the last decade New Brunswick 2021. At of current range, little research has done examine effects jumping these new habitats since recent establishment. Our objectives were evaluate: (1) how impact nitrogen carbon; (2) presence abundance non-native European earthworms Lumbricidae); (3) whether two sampling methods (i.e., mustard solution wooden discs) are equally effective at detecting worms. We sampled a residential property Oromocto, Brunswick, was first location where found province. did not significant on biomass or carbon content top 5 cm soil, but they significantly affect levels.

Abstract The people of New York have long benefited from the state's diversity ecosystems, which range coastal shorelines and wetlands to extensive forests mountaintop alpine habitat, lakes rivers greenspaces in heavily populated urban areas. These ecosystems provide key services such as food, water, forest products, flood prevention, carbon storage, climate moderation, recreational opportunities, other cultural services. This chapter examines how changes climatic conditions across state are affecting different types they provide, considers likely future impacts projected change. emphasizes change is increasing vulnerability existing stressors, habitat fragmentation invasive species, highlights opportunities for Yorkers adapt build resilience.

Earthworms are important soil biological indicators, but there is relatively little information on their communities in peri-urban soils and land uses the subtropics. In present paper, we describe earthworm occurrence relationships with biological, chemical physical attributes grass lawns native Atlantic Forest fragments Curitiba metropolitan area, using different sampling methods: quantitative handsorting, formalin extraction qualitative sampling. Overall, 785 individuals, of six families 12 species were found, four which (Glossoscolex embrapaensis, Fimoscolex nivae, Urobenus brasiliensis Ocnerodrilidae sp.), eight exotic (Dichogaster bolaui, Dichogaster sp., Murchieona minuscula, Aporrectodea rosea, Amynthas gracilis, morrisi, Metaphire californica Pontoscolex corethrurus). Grass had higher abundance (509 individuals) diversity (Shannon-Wienner, Simpson Pielou). Handsorting was most effective method (70% all individuals). Exotic predominanted areas (≥50% individuals), indicating a degree human disturbance. Biomass followed same pattern as abundance, being lawns. Multivariate analysis showed that did not have direct correlation forest acidity C contents.
