The impact of global warming on the niches and pollinator availability of sexually deceptive orchid with a single pollen vector

The Science of The Total Environment, Journal Year: 2021, Volume and Issue: 795, P. 148850 - 148850

Published: July 3, 2021

Orchidaceae are among the most endangered plants in world. Considering sensitive nature of pollinator-plant relationship vulnerable species which dependent on a single pollen vector. In this paper future distribution suitable niches Australian sexually deceptive orchid Leporella fimbriata and its pollinator (Myrmecia urens) was estimated using three machine learning algorithms. While potential range fringed hare depending modelling method will be larger or slightly reduced than currently observed, ant face significant loss niches. As result global warming overlap only vector probably decrease. The unavailability lead to decreased reproductive success as it great threat for L. existence.

Sea freshening may drive the ecological impacts of emerging and existing invasive non‐native species

Diversity and Distributions, Journal Year: 2020, Volume and Issue: 27(1), P. 144 - 156

Published: Nov. 16, 2020

Abstract Aim The spread of invasive non‐native species (INNS) will pose major threats to global biodiversity over the coming decades. However, predicting how key effects climate change influence abilities INNS establish and exert ecological impact is a challenge. One overlooked aspect expected freshening certain marine systems, which may interact with lead drastic on community structure stability. Location Baltic Sea, Europe. Methods Here, using three predatory amphipod crustaceans, we experimentally assessed salinity reduction affect impacts emerging INNS, Pontogammarus maeoticus , relative an existing Gammarus tigrinus trophically analogous native, salinus . We quantified per capita via comparative functional response method (prey consumption range prey densities) under predicted seawater scenario. then combined responses their life history traits compare population‐level potential (RIP) across salinities. Results Freshening substantially altered both compared native. First, P. G. increased freshening, while that native decreased. Second, RIP became consistently higher for freshening. Main conclusions Our methods thus reveal drive large shifts in dominance natives. With number introductions unlikely saturate near future, highlight need assess future alongside established non‐natives species, combination abiotic changes associated change.

Effects of Poplar Ecological Retreat on Habitat Suitability for Migratory Birds in China’s Dongting Lake Wetland

Frontiers in Environmental Science, Journal Year: 2022, Volume and Issue: 9

Published: Jan. 20, 2022

The Poplar Ecological Retreat (PER) project in Dongting Lake wetland is an important measure response to China’s ecological civilization construction policy, it aims remove eastern cottonwoods ( Populus deltoides ) that artificial large-scale planted this area and restore the natural state of wetland, has got a lot attention by society scholars. However, as one most wintering place for migratory birds world, impact PER on bird habitats not been evaluated. In paper, we used habitat suitability index model based remote sensing explore four mainly guilds (Anatidae, Charadriidae, Ardeidae Laridae) wetland. included grades: poorly (0–25), generally (25–50), moderately (50–75), highly (75–100). results showed poplars decreased significantly after was implemented. There negative correlation between poplar moderate grade Anatidae Ardeidae, positive general area. there no significant change different grades Charadriidae Laridae PER. Thus, improved but had effect Laridae. These conclusions could provide reference understanding living conditions waterbirds, determining priority protection areas maintaining biodiversity.

Intra-guild spatial niche overlap among three small falcon species in an area of recent sympatry

The European Zoological Journal, Journal Year: 2022, Volume and Issue: 89(1), P. 510 - 526

Published: April 7, 2022

Climate warming and land-use change are reshuffling the distribution of wild organisms on a global scale. Some species may expand their ranges colonize new regions, which greatly affect ecological interactions among pre-existing colonizers. In last decades, such processes have originated unique condition sympatry three Eurasian small Falco (common kestrel F. tinnunculus, lesser naumanni, red-footed falcon vespertinus) in intensively cultivated farmland habitats Po Plain (Northern Italy). This provides an excellent opportunity to investigate patterns spatial niche overlap during initial phases establishment sympatry. To species, we relied Environmental Niche Models (ENMs) based widespread breeding occurrence data obtained through field surveys citizen science programs (during 2018–2020 period). ENMs were bioclimatic variables ensemble modelling framework. We estimated species-specific relative contributions each climatic variable its response curves effect. Eventually, generated correlation maps potential species' distributions derive spatially-explicit predictions co-occurrence areas species. Overall, eco-climatic determinants similar, resulting strong association with intensive arable lands dry continental climate. Consistently, found high between suitability two highly suitable located Central-Eastern area Plain, corresponding core range both Conversely, common emerged as habitat generalist was widely distributed throughout Plain. Our findings suggest that recent kestrels falcons promote intra-guild competition.
