Ecological processes associated with different animal taxa in urban environments

et al. 2021

Urbanization is increasing globally with wide‐ranging consequences for biodiversity and the ecological processes it performs. Yet knowledge of the range of ecological processes supported by biodiversity in urban environments, and the different taxa that perform these processes is poorly understood. We used a text‐analysis approach to identify the research trends and gaps in knowledge in the literature on ecological processes provided by animals in urban environments. We found a divide in urban ecological processes research that grouped studies into those with an explicit link to ecological processes and those that focused on biodiversity and made an implicit link to ecological processes. We also found that the dominant taxa in urban ecological processes research were insects, which has more than twice as many studies as birds or mammals, potentially due to their recognized and explicit link to key processes and services (e.g., pollination, pollution biomonitoring) and disservices (e.g., pests, disease transmission). We found a further split between terrestrial and aquatic studies, with urban aquatic studies also declining in relative prevalence over the last 20 yr. To consolidate and advance research on ecological processes in urban environments, we suggest it will be important to bridge the divide between studies on explicit services and others on more general biodiversity. This might be achieved by placing greater focus on the processes provided by non‐insect taxa, and by integrating aquatic and terrestrial perspectives.

“…The specific name highlights the major decline in insect abundance across the globe (Hallmann et al 2017; Leather 2017; Cardoso & Leather 2019; Cardoso et al 2020), an event termed as Insect Apocalypse leading to the Ecological Armageddon. Though there are opposing views on the Insect Apocalypse (Goulson 2019; Schowalter et al 2019; Montgomery et al 2020; Saunders et al 2020); a more cautious approach towards insect conservation is mandated in the present scenario. The concept of Insect Apocalypse is perhaps premature, but it might be a near future possibility given the current trends in insect decline across multiple groups and regions.…”

A new species of Protosticta Selys, 1885 (Odonata: Zygoptera: Platystictidae) is described based on two male specimens collected from Kerala, at the southern end of the Western Ghats in India. We compared P. armageddonensis sp. nov. with the three closely similar Protosticta species recently described from the Western Ghats, namely P.anamalaica Sadasivan, Nair & Samuel, 2022, P. cyanofemora Joshi, Subramanian, Babu & Kunte, 2020, and P. monticola Emiliyamma & Palot, 2016, to provide comprehensive differential diagnosis. The new species is distinguished from its congeners by a combination of characters, including the structure of prothorax, caudal appendages, genital ligula, and markings on the 8th abdominal segment. A revised key of Protosticta spp. of the Western Ghats, based on mature male specimens is provided.

“…Because the Anthropocene is characterized by unprecedented rates of change, it is important to understand and predict spatio‐temporal dynamics of populations that can inform management and policy with the ultimate goal of reducing the likelihood of species extinction and consequent loss of ecosystem services that are essential for human well‐being. The urgency of the situation is reflected in recent suggestions that the planet is now entering its sixth major extinction period as well as in the controversy surrounding the announcement of biological Armageddon (Lister & Garcia, 2018; Schowalter et al, 2019; Willig et al, 2019).…”

Models that capture spatial and temporal dynamics are applicable in many scientific fields. Non‐separable spatio‐temporal models were introduced in the literature to capture these dynamics. However, these models are generally complicated in construction and interpretation. We introduce a class of non‐separable transformed multivariate Gaussian Markov random fields (TMGMRF) in which the dependence structure is flexible and facilitates simple interpretations concerning spatial, temporal and spatio‐temporal parameters. Moreover, TMGMRF models have the advantage of allowing specialists to define any desired marginal distribution in model construction without suffering from spatio‐temporal confounding. Consequently, the use of spatio‐temporal models under the TMGMRF framework leads to a new class of general models, such as spatio‐temporal Gamma random fields, that can be directly used to model Poisson intensity for space–time data. The proposed model was applied to identify important environmental characteristics that affect variation in the abundance of Nenia tridens, a dominant species of gastropod in a well‐studied tropical ecosystem, and to characterize its spatial and temporal trends, which are particularly critical during the Anthropocene, an epoch of time characterized by human‐induced environmental change associated with climate and land use.
