Invertebrate Numbers Nearly Halve As Human Population Doubles

However, the high number of snails and slugs was surprising, given that these animals are not such a common and visible feature of most people’s environments. Furthermore, it should be acknowledged that, while the survey was conducted in public spaces, those are places that attracts a portion of the public that is already more inclined toward science, nature or cultural activities. As such, our sample might not be representative of a broader and less scientifically-interested or literate public, which can bias our result.

This was expected given the age demographics we targeted and the distribution of the respondents’ age groups (Q2.7; Supplementary Figure S8). However, our study group was heavily skewed toward older people, with over 40% of respondents being over 50 years old . This abnormality in the age distribution of respondents heavily affected and maybe dictated the overall patterns of the answers, so we also analyzed the answers considering the age groups.

Whether you need a white-clawed crayfish survey, ecological input into an Environmental Impact Assessment or any other type of ecological work, we are here to help. In addition to these projects, we worked with our park teams to tailor park management schemes to boost biodiversity and make space for invertebrates. Initiatives like reducing mowing frequency, increasing the proportion of pollinator-friendly plants in our ornamental beds and leaving dead wood in situ all help to provide food and shelter for invertebrates.

Andrei in lethality tests.72Octolasion tyrtaeum, a common species in many Argentine agricultural ecosystems, was more sensitive than E. Andrei to glyphosate, when testing adult lethality and variation of biomass.73 Accumulation and toxicity of metals were studied using Lumbricus rubellus , Aporrectodea longa , and Eisenia fetida (ultra-epigeic) with 28 days of exposure in two soils; under these circumstances, L. Rubellus was the most sensitive species.66 In ecotoxicological assessment of imidacloprid, E. Fetida responded with significant avoidance behavior in all tested concentrations, while L. The first part of this chapter presents general considerations on soil invertebrates, such as their representativeness in the animal kingdom and the ways they are classified into groups, in addition to some morpho/physiological characteristics and habit requirements. This part also lists the species of soil invertebrates currently used in standard laboratorial ecotoxicological assays and the improvements that have been made in these type of assays, including the selection of new standard test species.

Linking the new information to something important to the public, especially as part of a narrative or story, is deemed the most efficient way to communicate science (Dahlstrom, 2014; Berentson-Shaw, 2018). Furthermore, the use of narratives to convey research is linked to faster and better comprehension and to greater recall by the public (Berentson-Shaw, 2018). It has been argued that, when it comes to species that invoke feelings of disgust , greater knowledge of a particular species correlates with a more positive attitude toward it (e.g., Prokop et al., 2008; Prokop et al., 2009). Evidence for this relationship between knowledge and attitude is not sound, however, and research based on this model tends to focus only on one particular species or issue (e.g., Prokop et al., 2008; Prokop et al., 2009; Prokop et al., 2010). When lacking motivation to learn or pay attention, people fall back to mental shortcuts and emotion, typically in detriment of actual knowledge (Bubela et al., 2009).

3) Two respondents reported that a good way to entice the public and make them perceive the importance of invertebrates is to link these animals to the usual “relatable” fauna. One malacologist provided an example of the decrease in songbird populations caused by the decline of land snails, which are a source of calcium for the former. 4) One respondent spoke of using pop culture to start the conversation and another respondent, a paleontologist, also followed this line, connecting the monsters from the Pokémon franchise to actual fossils. The link between pop culture and conservation in science communication is a strong point and is starting to be explored in the literature (Dorward et al., 2017; Salvador, 2017; Patterson and Barratt, 2019). In fact, circa 20% of our respondents (Q1.15, Figure 2G) reported using pop culture as a starting point in their science communication. Good science communication should give the public the tools to make informed decisions and take action, which can be particularly important for nature conservation.

If that garden had even a small pond, a whole suite of aquatic and marginal species would also be supported. A healthy urban greenspace should contain a great variety of invertebrates, among the more familiar of which are beetles, spiders, ants, true bugs , butterflies and moths, flies, wasps, centipedes, millipedes, woodlice, earthworms, nematode worms, mites and springtails. For example, around 55,000 springtails were found to be living in a single square metre of soil on a green roof in an urban area of Hanover, Germany .

An invertebrate refers to any of the animals lacking a vertebral column. The term invertebrate came from the Latin in-, meaning “not” and vertebrate defined as an animal with vertebrae. Hence, invertebrates are a group of animals that do not have vertebrae .
