Effects of Ingestion of Lithic Particles on Growth of the Apple Snail Pomacea canaliculata (Caenogastropoda, Ampullariidae) [PDF]

, 2016
Lithic particles are a common feature in the digestive tract of freshwater snails. Their role in the digestive processes has been demonstrated in some microphytophagous and detritivorous species, as they enhance growth, assimilation and reproduction.

Value-chain analysis of freshwater apple snail (Pila globosa) used for on-farm feeds in the freshwater prawn farming sector in Bangladesh

International Journal of Agricultural Research, Innovation and Technology, 2013
Growth of the freshwater prawn (Macrobrachium rosenbergii) sector in Bangladesh since 1970s has been supported by natural availability of freshwater apple snail (Pila globosa), used for on-farm prawn feeds.

Apple Snail Perivitellin Precursor Properties Help Explain Predators’ Feeding Behavior [PDF]

Physiological and Biochemical Zoology, 2017
In contrast with vitellogenin maturation, it is unknown whether gastropod perivitellin precursors are subject to large structural changes. The gastropod reproductive tract includes an accessory organ, the albumen gland (AG), that produces and secretes perivitelline fluid. In the apple snail Pomacea canaliculata, the large, reddish-pink AG provides eggs

Agglutinating activity and structural characterization of scalarin, the major egg protein of the snail Pomacea scalaris (d'Orbigny, 1832). [PDF]

PLoS ONE, 2012
Apple snail perivitellins are emerging as ecologically important reproductive proteins. To elucidate if the protective functions of the egg proteins of Pomacea canaliculata (Caenogastropoda, Ampullariidae), involved in embryo defenses, are present in ...

Experimental evidence of internal transport of invasive apple snail eggs by waterbirds [PDF]

Aquatic Invasions
The potential role of waterbirds in the dispersal of invasive apple snail Pomacea canaliculata was evaluated by feeding their eggs to mallards Anas platyrhynchos and quantifying the recovery of intact and viable eggs in their faeces and regurgitations. A

The invasive apple snail Pomacea canaliculata in Indonesia: a case study in Lake Rawa Pening, Central Java

BIO Web of Conferences, 2020
The occurrence of the invasive apple snail Pomacea canaliculata in Indonesia was first reported in 1984. The species was introduced as an ornamental aquarium pet. Since then, people have begun to culture the snail in ponds usually adjacent to rice fields.

An invasive prey alters local and landscape contributions of sources and sinks for an endangered predator. [PDF]

Ecology
Abstract Source‐sink dynamics are a cornerstone of theory for spatially structured populations. Despite long‐standing interest, understanding temporal variation in source‐sink dynamics in wild populations remains rare. Biological invasions have the potential to alter source‐sink dynamics for native species, which may change over time as invasions ...

Biodiesel production process catalyzed by acid-treated golden apple snail shells (Pomacea canaliculata)-derived CaO as a high-performance and green catalyst

Engineering and Applied Science Research, 2022
In this study, acid-treated golden apple snail shells (Pomacea canaliculata)-derived calcium oxide (CaO_tr) were used as a high-performance catalyst for the transesterification of palm oil and waste cooking oil (WCO) because the golden apple snail shells

What's in a compound? Review article on Lieber and Štekauer (eds) 2009. 'The Oxford Handbook of Compounding' [PDF]

, 2011
The Oxford Handbook of Compounding surveys a variety of theoretical and descriptive issues, presenting overviews of compounding in a number of frameworks and sketches of compounding in a number of languages. Much of the book deals with Germanic noun–noun
