Abstract: Ruminant animals have a great advantage over simple-stomached animals, as their digestive process is able to release the energy contained in cellulosic material through carbohydrate fermentation by microorganisms enzymes from the rumen environment. However, carbohydrate fermentation results not only in short chain fatty acids (SCFA) but also in less desirable products such as heat, as well as methane (CH4) and carbon dioxide (CO2) gases which represents energy loss for the animal estimated in 2 to 12% of gross energy from feed (Johnson and Johnson, 1995). As an adult ruminant can produce up to 17 liters of methane per hour and this gas cannot be metabolized even by rumen microorganisms, most of it is removed from rumen by expiration or eructation (Moss, 1993), and released in the environment. There are different techniques for methane emissions measurements by ruminants in production conditions; among them there is one that uses an inert gas tracer, sulphur hexafluoride (SF6). This technique results in a precise estimative of methane production by the animal besides enabling the evaluation of animals in normal pasture conditions, it consists in placing a permeation tube, which releases SF6 at a previously known rate in the rumen, where by the contractions of this organ, CH4 and SF6 gases are released by eructation and samples are collected close to mouth and nostrils. This method assumes that the standard of SF6 emission simulates the standard of CH4 emission. The flow of CH4 released by the animal is calculated in relation to SF6 flow (Westberg et al., 1998).The objective with the present study was to evaluate energy sources inclusion in cattle diets on methane production determined by sulphur hexafluoride (SF6) tracer gas technique.

Urban green areas can have a high impact on soil fauna due the environmental changes caused by human activities. This work aimed to assess earthworm populations in urban sites in the city of Curitiba, Paraná, Brazil. Earthworms were sampled in two urban sites: the Campus Ecoville of the Universidade Positivo and the Casa Verde space and in two land use systems (Grass Lawn and Native Vegetation), in the summer of 2018 and 2019 and winter of 2019. A total of 1052 individuals were found, belonging to five families and 12 species were identified, of which five are native: Glossoscolex sp.55, Fimoscolex sp.36, Fimoscolex sp.37 (Glossoscolecidae), Andiorrhinus duseni (Rhinodrilidae) and Ocnerodrilidae sp.43 (Ocnerodrilidae) and seven are exotic species: Amynthas corticis, Amynthas morrisi, Metaphire californica, Metaphire schmardae (Megascolecidae), Dendrodrilus rubidus (Lumbricidae) and Pontoscolex corethrurus (Rhinodrilidae). Of the five native species found, four are new species and will be described in the future and the specie A. duseni belongs to the group known as giant earthworms (minhocuçu) with specimens larger than 30cm. Despite the predominance of exotic species (n=932) compared to native species (n=114), the presence of new species may indicate that the managed environments can preserve native species. Moreover, the difference in the total number (native vs. exotic) can be attributed to the ability of the exotic species to survive human disturbances. |
