“…Alongside this, invasion success is generally higher when species are introduced to climates similar to those occupied in the native range (Williamson 1996;Jeschke et al 2014), and 'climate matching' is therefore an important component of assessing risk of invasion by alien species (Thuiller et al 2005). However, reported mismatches between native and invasive ranges, termed climate niche shifts (Guisan et al 2014), necessitate research on the ecological and evolutionary processes that allow species to tolerate climates different from their native ranges (Sexton et al 2002;Kelley et al 2013). To identify how such evolutionary, environmental and human-mediated factors combine to underpin successful invasions, reconstructing pathways of invasion and identifying ancestral source populations are essential prerequisites (Sax et al 2005;Estoup & Guillemaud 2010;Ascunce et al 2011;Lombaert et al 2011;Kirk et al 2013;Perdereau et al 2013).…”

Invasive species present a major threat to global biodiversity. Understanding genetic patterns and evolutionary processes that reinforce successful establishment is paramount for elucidating mechanisms underlying biological invasions. Among birds, the ring-necked parakeet (Psittacula krameri) is one of the most successful invasive species, established in over 35 countries. However, little is known about the evolutionary genetic origins of this species and what population genetic signatures tell us about patterns of invasion. We reveal the ancestral origins of populations across the invasive range and explore the potential influence of climate and propagule pressure from the pet trade on observed genetic patterns. Ring-necked parakeet samples representing the ancestral native range (n = 96) were collected from museum specimens, and modern samples from the invasive range (n = 855) were gathered from across Europe, Mauritius and Seychelles, and sequenced for two mitochondrial DNA markers comprising 868 bp of cytochrome b and control region, and genotyped at 10 microsatellite loci. Invasive populations comprise birds that originate predominantly from Pakistan and northern areas of India. Haplotypes associated with more northerly distribution limits in the ancestral native range were more prevalent in invasive populations in Europe, and the predominance of Asian haplotypes in Europe is consistent with the higher number of Asian birds transported by the pet trade outside the native range. Successful establishment of invasive species is likely to be underpinned by a combination of environmental and anthropogenic influences.

“…These robust organisms are of special interest, showing high tolerance to environmental and physiological changes. It is this tolerance to starvation (Matozzo et al, 2011), cold temperature (Kelley et al, 2013), hypoxia (Simonik and Henry, 2014), water alkalization (Cripps et al, 2013) and a wide diversity of pollutants (Henry et al, 2012) that has allowed, for example, the invasive Atlantic green crab Carcinus maenas to colonize many different regions of the world, and the Mediterranean green crab Carcinus aestuarii to invade Japan (Carlton and Cohen, 2003).…”

Osmoregulating decapods such as the Mediterranean green crab Carcinus aestuarii possess two groups of spatially segregated gills: anterior gills serve mainly respiratory purposes, while posterior gills contain osmoregulatory structures. The co-existence of similar tissues serving different functions allows the study of differential adaptation, in terms of free radical metabolism, upon salinity change. Crabs were immersed for 2 weeks in seawater (SW, 37 ppt), diluted SW (dSW, 10 ppt) and concentrated SW (cSW, 45 ppt). Exposure to dSW was the most challenging condition, elevating respiration rates of whole animals and free radical formation in hemolymph (assessed fluorometrically using C-H 2 DFFDA). Further analyses considered anterior and posterior gills separately, and the results showed that posterior gills are the main tissues fueling osmoregulatory-related processes because their respiration rates in dSW were 3.2-fold higher than those of anterior gills, and this was accompanied by an increase in mitochondrial density (citrate synthase activity) and increased levels of reactive oxygen species (ROS) formation (1.4-fold greater, measured through electron paramagnetic resonance). Paradoxically, these posterior gills showed undisturbed caspase 3/ 7 activity, used here as a marker for apoptosis. This may only be due to the high antioxidant protection that posterior gills benefit from [superoxide dismutase (SOD) in posterior gills was over 6 times higher than in anterior gills]. In conclusion, osmoregulating posterior gills are better adapted to dSW exposure than respiratory anterior gills because they are capable of controlling the deleterious effects of the ROS production resulting from this salinity-induced stress.

“…Interestingly, despite the large range of ~1300 km, only one haplotype has been found throughout this range, indicating a high degree of genetic similarity across the population (Tepolt et al 2009). Nonetheless, this northeastern Pacific population of C. maenas has site-specific organismal thermal tolerance thresholds and differential expression of several key proteins involved in the regulation of cellular thermotolerance (Kelley et al 2011(Kelley et al , 2013. Together, these organismal and cellular differences highlight the role that environmental temperature has played in driving the physiological variation in phenotype that currently exists across this recipient range (Kelley et al 2011;Kelley 2014).…”

Thermogeographic variation in body size of Carcinus maenas, the European green crab

biogeographic differences in size (carapace width) exist for a recent invasion of the non-native European green crab, Carcinus maenas, along the west coast of North America. We assembled trapping and temperature data collected from 10 sites along the western North American coast over a 5-year period. We also conducted a literature review of C. maenas size across their native range. Our results indicate that adult body size shows negative correlation with environmental temperature in both the native and invaded ranges, conforming to the temperature-size rule for ectotherms. Given the short time since colonization and lack of evident genetic structure across the invasive range, it may be that phenotypic plasticity in response to environmental temperature is driving this relationship. Forces that shape the phenotypic trajectory of species may play an important role in both invasion dynamics and subsequent ecological impacts.
