“…In accordance with our hypothesis, macroinvertebrate community structure differed between stream types, which agrees with other studies addressing invasion effects on benthic macroinvertebrate communities (Lowe et al, 2008;Serra et al, 2013;Seeney et al, 2019;Little et al, 2021). In particular, we found higher EPT taxa richness and higher number of EPT taxa as indicators for streams flowing through native than invaded forests, as also seen in the case of L. maacki (Little et Table 3.…”

“…Maxim. in the American Midwest also led to changes in benthic macroinvertebrate community structure along an invasion gradient, with the most invaded stream showing the lowest percentage of sensitive taxa (Little et al, 2021). In central and southern Scotland, invasion of riparian areas by exotic plants was associated with a decrease in the diversity and an increase in the abundance of stream benthic macroinvertebrates, and changes in community structure in autumn (but not in spring) (Seeney et al, 2019).…”

“…The riparian forest determines many of the stream characteristics; e.g., canopy cover influences solar exposure of the stream bed and water temperature (Beschta, 1997), nutrient uptake by and litter inputs from the riparian forest affect the water chemical composition (Dosskey et al, 2010) and the latter also affects the benthic organic matter standing stock (Abelho & Graça, 1996;Molinero & Pozo, 2004), and the supply of branches and logs to streams affects current velocity and depth conditions and changes microhabitat distribution (Gerhard & Reich, 2000). Consequently, the riparian forest influences the instream energetic pathways (autotrophic vs. heterotrophic) and the structure of aquatic communities (Hawkins et al, 1982;Ferreira et al, 2016;Little et al, 2021).…”

The riparian forest determines many of the stream characteristics such as physicochemical variables and the availability and quality of food resources for aquatic communities. In central Portugal, native mixed deciduous forests are being heavily invaded by Acacia dealbata, which is an evergreen and nitrogen-fixing tree species, but effects on stream benthic macroinvertebrate communities are unknown. We assessed invasion effects on macroinvertebrate communities by comparing streams flowing through native forests (native streams) and streams flowing through forests heavily invaded by A. dealbata (invaded streams), in central Portugal. We did not find major differences in macroinvertebrate abundance, total taxa richness or diversity between native and invaded streams, due to high variation among native streams. However, taxonomic structure of macroinvertebrate communities differed between stream types, with invaded streams showing lower percentage of sensitive taxa. Macroinvertebrate communities structure based on functional feeding groups also differed between stream types, with a tendency for higher abundance of shredders and scrapers/grazers and lower abundance of filter feeders in native than invaded streams, probably due to altered composition of leaf litter inputs and canopy cover within invaded streams. Our findings suggest that invasion by A. dealbata affect macroinvertebrate community mostly in terms of taxonomic and functional structure. Since A. dealbata is rapidly spreading in all southern Europe, this study highlights the importance of enhancing the comprehension of its impact on aquatic communities to identify ecological risks and formulate effective mitigation strategies.

“…Nevertheless, the real danger posed by allochtonous invaders should not be presumed, instead it should be estimated for each case, different management options should be evaluated in relation to the arrival of a new species 11 , 12 , and alien vs alien and invasive species should be clearly differentiated 13 . One of the most accredited solutions is the eradication of the invading species 14 .…”

The spreading of invasive species in new continents can vary from slow and limited diffusion to fast colonisations over vast new areas. We studied the sacred ibis Threskiornis aethiopicus along a 31-year period, from 1989 to 2019, with particular attention to the first area of release in NW Italy. We collected data on species distribution through observations by citizen science projects, population density by transects with distance method, breeding censuses at colonies, and post breeding censuses at roosts. The birds counted at winter roosts in NW Italy increased from a few tens up to 10,880 individuals in 2019. Sacred ibises started breeding in 1989, with a single nest in north-western Italy. The number of breeders remained very low until 2006, when both overwintering and breeding sacred ibises started to increase exponentially and expand their range throughout northern Italy with isolated breeding cases in central Italy. In 2019, the number of nests had increased to 1249 nests in 31 colonies. In NW Italy, the density of foraging birds averaged 3.9 ind./km2 in winter and 1.5 ind./km2 in the breeding period, with a mean size of the foraging groups of 8.9 and 2.1 birds respectively. Direct field observations and species distribution models (SDM) showed that foraging habitats were mainly rice fields and wetlands. A SDM applied to the whole Italian peninsula plus Sardinia and Sicily showed that the variables best related to the SDM were land class (rice fields and wetlands), altitude, and the temperature seasonality. The areas favourable for species expansion encompass all the plains of Northern Italy, and several areas of Tuscany, Latium, Sardinia, and Apulia.
