“…These biases are generally attributed to the legacy of species association with human‐made and disturbed habitats embedded in dispersal networks (Pearson, Ortega, Eren, & Hierro, 2018; Pyšek et al, 2015). As such, and although this may be counter‐intuitive on a first sight (Price & Pärtel, 2013), our findings are not in contradiction with the limiting similarity concept (MacArthur & Levins, 1967): the mechanisms of biotic resistance involving functional similarity (notably through competition) are indeed undermined by disturbance (Elton, 1958) as demonstrated with our model community (Leclerc et al, 2021). Importantly, our model community is also composed of multiple foundation species and prone to complex epibioses involving neutral to positive interactions, which also affect its invasibility (Bulleri et al, 2008; Leclerc & Viard, 2018).…”

“…Multiple succession trials and disturbance experiments of fouling communities in the study region suggested that most of the neocosmopolitans are opportunistic, stress‐tolerant or both (Leclerc et al, 2021; Leclerc, Viard, González‐Sepúlveda, et al, 2020). By analysing their traits, the present study confirms this hypothesis and provides further elements to disentangle associated mechanisms.…”

AimTrait‐based approaches are powerful to examine the processes associated with biological invasions. Functional comparison among native and non‐indigenous species (NIS) can notably infer whether novel assemblages result from neutral or niche‐based assembly rules. Applying such a framework to biofouling communities, our study aimed to elucidate their distributions within two marine urban habitats (namely floating vs. nonfloating habitats).LocationSoutheast Pacific—Central Chilean coastline.MethodsHere, we examined the distribution of 12 functional traits in fouling communities established on settlement plates, after 3 and 13 months of deployment in the two habitats and across ports in Central Chile. Based upon previously described differences of assemblages and NIS contribution across habitats, we hypothesized that nonindigenous, cryptogenic and native taxon pools would be functionally distinct (and trait biased), and that functional diversity and structure would vary across habitats and successional stages.ResultsOur results show, as anticipated, that nonindigenous (13 taxa), cryptogenic (12) and native (18) taxon pools are functionally distinct, though overlapping in the trait space. Non‐indigenous species are rather related to colonizing traits, while native species are more related to competitive traits. Only one widespread NIS was functionally similar to the late successional and most competitive native species, including taxa elsewhere invasives. Despite differences in taxonomic composition between habitats, we did not observe functional differences between them. In contrast, temporal variations across colonization stages were detected along with an increased contribution in large and long‐lived taxa, together with site‐specific trajectories.Main ConclusionsWe conclude that the functional distinctness among nonindigenous, cryptogenic and native taxa occupying artificial habitats in ports reflects niche‐based processes. Site‐specific trajectories indicate that scale‐dependent assembly processes, such as dispersal and species interactions, are at play.

“…These ecological drivers include topography and micro-climate (elevation, slope, aspect, and water distance) and anthropogenic-related factors (distance to human paths, roads, settlements, land use, and population density). These factors could potentially influence the long-term habitat composition, structure, or function, that can be identified with the help of species distribution modeling [ 52 , [57] , [58] , [59] , [60] ], as well as potentially weaken species resilience to future disturbances [ [61] , [62] , [63] ].…”

“…The important ecological factors include altitude, slope, aspect, leaf litter, disturbances (e.g., proximity to settlements and frequency of fire) and vegetation or food resources (e.g., trees and grass). These factors may affect long-term forest composition, structure, or function (Franklin et al, 2002;Palik et al, 2002;Hessburg et al, 2016) and compromise resilience to subsequent disturbance (Radeloff et al, 2000;Hessburg et al, 2019;Leclerc et al, 2021).…”

Habitat preference and distribution of Chinese pangolin and people’s attitude to its conservation in Gorkha District, Nepal

et al. 2023

The Chinese pangolin (Manis pentadactyla) has experienced a rapid population decline throughout its distribution. In Nepal, it mostly occurs outside protected areas; therefore, habitat degradation due to anthropogenic activities is one of the major threats to its survival. However, the scarcity of information on the ecology and distribution of pangolins impedes evidence-based conservation of this species in Nepal. Its habitat preferences and distribution and the factors influencing people’s attitude to its conservation were studied in Gorkha District in central Nepal. Thirteen transects, each 0.5 km in length, were used for recording burrows indicating the presence of pangolin. In total, 124 burrows were recorded, of which 38 were new and 86 were old, which indicated a clumped distribution. Based on the highest percentage frequency of occurrence, most burrows occurred between 650 and 800 m a.s.l., in areas with a south-facing aspect, with moderate canopy cover, in forest, red soil and gentle terrain. The logistic regression model revealed that habitat type, soil type, crown cover, terrain, and distance to water were the most important factors affecting pangolin presence. In total, 87 households and 9 key informants were interviewed using questionnaires to determine the people’s knowledge of pangolins and attitude to their conservation. More than 50% of the respondents had seen pangolin in the areas studied and had a general knowledge of their habitat and benefits. However, most of them were unaware that it was illegal to hunt pangolins and were involved in opportunistic hunting for meat consumption. Pangolins were mostly recorded in forest at altitudes 650–800 m a.s.l., with moderate canopy cover, red soil, and close to a source of water; habitat, soil, canopy cover, terrain, and distance to water were statistically significantly associated with the presence of pangolin burrows. This study revealed that an increase in public awareness (mainly through education) would help to increase the likelihood of pangolin survival. These results can also serve as guidelines for protecting pangolin habitats for use by local authorities.
