“…Thus, only a single cohort composes each population in discontinuous generation. This form of population dynamics is found in slugs of Arion lusitanicus (Kozlowski and Sionek, 2000), Deroceras reticulatum (Natalia et al, 2008), and snails of Theba pisana (Heller, 1982), Xeropicta arenosa (Staikou and Lazaridou-Dimitriadou, 1991). Although some populations of Xeropicta derbentina (Kiss et al, 2005) and Succinea putris (Kuznik-Kowalska et al, 2013b) exhibit semelparous and annual life histories, it is unclear whether adults disappear in a season.…”

Diverse life histories have been documented in terrestrial pulmonates, which inhabit different regions in climate. Life history traits are often phenotypically plastic and vary depending on the environment. Thus, surveys using designs that control for the confounding effects of environment are needed to evaluate the evolutionary differences between populations of closely related species in the wild. We examined the life histories of sibling species of terrestrial pulmonate within two regions of similar climates. Bradybaena pellucida (BP) is endemic to Japanese islands, and has recently been expanding its distribution northeastward, whereas B. similaris (BS) has been introduced by humans into temperate and tropical regions worldwide. We found that these species exhibit discrete differences in population dynamics and life cycle, despite their close relatedness. The annual life cycle of BP is synchronized among individuals in a population. Thus, BP is univoltine with discontinuous generation. In contrast, BS individuals do not synchronize their growth or reproduction, and thus exhibit overlapping generations. Our results indicate that synchronized and non-synchronized population dynamics diverge relatively rapidly in semelparous pulmonates. This type of difference has not been documented in pulmonate life history, and may have been overlooked because only a few studies have explicitly compared life cycles of closely related species within the same climate. Our results provide a basis for further studies of life history evolution in pulmonates.Key words: life cycle, life history, population dynamics, land snail, Bradybaena, Gastropoda INTRODUCTIONThe life histories of animals and plants can be categorized as iteroparous or semelparous; iteroparity refers to repeated reproduction over separate periods in individual lifetime, whereas semelparity is characterized by death after reproduction in a single period (Roff, 1992;Young, 2010). This way of contrasting different life histories provides useful insights into the evolution of reproductive strategies. Among diverse organisms, however, distinctions between these categories may not necessarily be generally applicable, and remain controversial (Kirkendall and Stenseth, 1985;Hughes and Simons, 2014).In land gastropods including snails and slugs, Heller (2001) reviewed literature of 20 iteroparous and 15 semelparous genera. Since then, probable iteroparity in the genus Helicodonta (Maltz, 2003) and semelparity in Pupilla (Pokryszko, 2001) and Trochulus (Kuznik-Kowalska et al., 2013a) have been reported. Populations of Xerolenta obvia vary from iteroparity to semelparity, perhaps depending on environment (Lazaridou and Chatziioannou, 2005). Even among terrestrial pulmonates, wide ranges of variation have been documented in life span and cycle and other reproductive traits across diverse climatic ranges (Heller, 1990(Heller, , 2001Maltz, 2003;Kramarenko, 2013).To elucidate the processes and mechanisms of ecology and evolution responsible for the diversity of life history, t...

“…Up to 30% of slugs hatch before winter, and the remainder the following spring . In the vegetation season there are two peaks of numbers, the first in mid May, and the second -characterized by greater numbers -in the first half of August (Kozłowski 2000a;Kozłowski and Sionek 2000b).…”

The Significance of Alien and Invasive Slug Species for Plant Communities in AgrocenosesThis paper lists alien invasive species of slugs occurring on crops grown in the ground and under covers, as well as in adjacent habitats. It gives a description of their origin, distribution within Poland, frequency of occurrence in different habitats, and an evaluation of the danger to cultivated plants posed by particular slug species. Based on reports in the literature and the results of original research, basic data is presented concerning the biology and harmfulness of these slugs on crops. The potential risk of the spreading of invasive slug species is evaluated, as well as their adverse impact on crop plants. It has been concluded that a major risk to the biodiversity of agrocenoses and to cultivated plants is currently posed by the slugsArion lusitanicus, A. rufusandA. distinctus. These slugs are spreading rapidly within Poland, often occur in large numbers, and do significant damage to various species of plant.

“…Initially it occurred only in one locality, in the village of Albigowa near Rzeszów (Subcarpathian region), in subsequent years it spread over a considerable area in that region, south-east of Rzeszów. In 1997-2007 it was recorded from over 100 localities in Poland (KOZ£OWSKI 2000, 2001, KOZ£OWSKI & SIONEK 2000, KOZ£OWSKI & KOZ£OWSKI 2011. In Poland the slug is synanthropic and most often occurs in large numbers in gardens and cultivated fields located near buildings, among shrubs, in parks, cemeteries and in wasteland.…”

Within the last decades the slug Arion lusitanicus has expanded its range over wide areas of Europe, in most of them it is now a serious pest. Poland has been invaded relatively recently (since the late 1980s). Considering the ecological importance of the slug, very little is known yet about the mechanism of invasion, establishment of new populations and influence on the native fauna and flora. The analysis of nucleotide sequences of mitochondrial cytochrome oxidase subunit 1 gene (cox1) revealed a great inter-and intrapopulation variation in the Polish populations of A. lusitanicus. The differentiation of all the studied Polish populations of A. lusitanicus is 0.2-2.2%, while two analysed Belgian populations are monomorphic and moderately genetically diverse at 0.8%. This indicates a heterogeneous origin of the Polish populations, probably resulting from multiple independent introduction events. The genotype found in the first four Polish populations (S. Poland) suggests that their origin is different from the remaining populations.
