The spread of non‐native species
ABSTRACT The global redistribution of species through human agency is one of the defining ecological signatures of the Anthropocene, with biological invasions reshaping biodiversity patterns, ecosystem processes and services, and species interactions globally.

Growth and Reproduction of Planorbarius corneus (Linnaeus, 1758) in Laboratory Conditions
This study presents the results of observation on growth and reproduction of Planorbarius corneus (Linnaeus, 1758) (Gastropoda, Pulmonata) over the course of several years of continuous rearing in the laboratory in order to use them as test organisms for

Why pygmy snails lay giant eggs: the kiwi syndrome
Some minute land snails lay disproportionally large eggs, and the reason is unknown. A possibility is the “Kiwi Syndrome”, in which natural selection pressures associated with low egg predation, heavy predation of the young, and a minimal viable size for hatchlings, force small females to invest in relatively large offspring at the cost of reduced ...

The impacts of biological invasions
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Photoperiodic Stimulation of Egg Laying in the Land Snail Helix aspersa [PDF]
WE report here early results of an investigation of the relation between photoperiod and various aspects of the physiology and reproduction of the land snail, Helix aspersa. It was suggested recently that maturation of gametes may be initiated by annual temperature fluctuations and is perhaps correlated with changes in illumination. There does not seem

ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...
