Mariscal 1970a; 1970b; Elliot & Mariscal 2001; Fricke 1973; 1974; 1983; 1987; Miyagawa K. & Hidaka T. 1980; Murata et al. 1986; Fautin 1986; 1991; 1992; Bauer 2004; Arvedlund & Takemura 2005; Holbrook & Schmitt 2005; Chadwick & Arvedlund 2005; Porat & Chadwick-Furman 2004; 2005; Roopin et al. 2008), ale méně známé jsou vztahy mezi sasankami a dalšími bezobratlými, např. krevetami. Informace o ekologii a chování některých sasankových krevet téměř nemáme, i přestože o těchto vazbách víme (Bauer 2004; Bruce 1976a; 1976b; 1985; Herrnkind et al. 1976; Mercado & Capriles 1982; Criales 1979; 1984; Jonsson et al. 2001; Khan et al. 2003; 2004; Calado et al. 2007). Velmi mnoho studií je zaměřeno na preferenční vazby mezi určitými druhy sasankových ryb a krevet k určitým druhům sasanek (Bruce 1976a; 1976b; Stanton 1977; Suzuki & Hayashi 1977; Mercado & Capriles 1982; Fautin 1986; Fautin et al. 1995; Guo et al. 1996; Khan et al. 2003; 2004; Calado et al. 2007). Avšak druh sasanky není jediný faktor, který ovlivňuje volbu určitého jedince. Krevety mohou být významně ovlivněny prostředím, v jakém se daná sasanka nachází. Třeba silný proud může krevetě zabránit v usazení na sasance, stejně jako jiné již asociované organismy mohou krevetě v kolonizaci sasanky aktivně bránit. Abychom doopravdy pochopili, proč si krevety vybírají určité sasanky, musíme zaznamenat celou řadu environmentálních faktorů (hloubka, přítomnost asociovaných organismů, podklad sasanky, její velikost atd.). Indický a Tichý oceán jsou výbornými geografickými oblastmi pro společné studium sasankových ryb a krevet, jelikož spolu koexistují na stejných druzích sasanek. Můžeme zde tedy zkoumat nejen interakce mezi rybou a sasankou nebo krevetou a sasankou, ale i mezi krevetou a asociovanou rybou. I přesto, že je v této oblasti velká druhová diverzita sasankových krevet s mnoha endemickými druhy, existuje pouze málo vědeckých prací z oblasti Indo-Pacifiku.

Abstract A new genus of the subfamily Pontoniinae, Ancylomenes gen. nov. is established for the ‘Periclimenes aesopius species group’ of the genus Periclimenes Costa. The new genus is distinguished from other genera of Pontoniinae on account of the strongly produced inferior orbital margin with reflected inner flange, and the basicerite of the antenna armed with an angular dorsal process. Fourteen species have been previously recognized as belonging to the ‘P. aesopius species group’. One Eastern Pacific species (P. lucasi Chace), and two Atlantic species (P. anthophilus Holthuis & Eibl- Eibesfeldt, and P. pedersoni Chace) are now also placed in Ancylomenes gen. nov. A further new species associated with a cerianthid sea anemone, A. luteomaculatus sp. nov. is described and illustrated on the basis of specimens from the Ryukyu Islands, southern Japan, and Philippines.

    Baeza et al. Helgol Mar Res (2017) 71:17 DOI 10.1186/s10152-017-0497-8 Helgoland Marine Research ORIGINAL ARTICLE Open Access Host‑use pattern of the shrimp Periclimenes paivai on the scyphozoan jellyfsh Lychnorhiza lucerna: probing for territoriality and inferring its mating system J. Antonio Baeza1,2,3*, Samara de Paiva Barros‑Alves4,5, Rudá Amorim Lucena6, Silvio Felipe Barbosa Lima7,8 and Douglas Fernandes Rodrigues Alves4,5 Abstract In symbiotic crustaceans, host-use patterns vary broadly. Some species inhabit host individuals solitarily, other spe‑ cies live in heterosexual pairs, and even other species live in aggregations. This disparity in host-use patterns coupled with considerable diferences in host ecology provide opportunities to explore how environmental conditions afect animal behavior. In this study, we explored whether or not symbiotic crustaceans inhabiting relatively large and structurally complex host species live in aggregations. We expected Periclimenes paivai, a small caridean shrimp that lives among the tentacles of the large and morphologically complex scyphozoan jellyfsh Lychnorhiza lucerna, to live in groups given that the host traits above constraint host-monopolization behaviors by symbiotic crustaceans. We described the population distribution of P. paivai during a bloom of L. lucerna near the mouth of the Paraíba River estuary in Paraíba, Brazil. The population distribution of P. paivai did not difer statistically from a random Poisson dis‑ tribution. Male shrimps were most often found dwelling on the surface of L. lucerna individuals as small groups (2–4 individuals), in agreement with expectations. Periclimenes paivai is a sexually dimorphic species with males attaining smaller average body sizes than females and exhibiting no elaborated weaponry (claws).

  • Comparative Diversity of Anemone-Associated Fishes and Decapod Crustaceans in a Belizean Coral Reef and Seagrass System
    Marine Biodiversity (2019) 49:2609–2620 https://doi.org/10.1007/s12526-019-00993-5 ORIGINAL PAPER Comparative diversity of anemone-associated fishes and decapod crustaceans in a Belizean coral reef and seagrass system Rohan M. Brooker1,2 & William E. Feeney3,4 & Tiffany L. Sih5,6 & Maud. C. O. Ferrari7 & Douglas P. Chivers2 Received: 16 April 2019 /Revised: 5 July 2019 /Accepted: 12 July 2019/Published online: 19 August 2019 # Senckenberg Gesellschaft für Naturforschung 2019 Abstract Within tropical coastal habitats such as coral reefs and seagrass meadows, sea anemones (Actiniaria) provide microhabitats for a diverse range of fauna. However, the mechanisms that enable these interactions, and how actiniarian diversity and abundance mediates associate assemblages, remains poorly understood. Here, we compared sea anemone species richness and abundance with that of their associated decapod crustaceans and teleost fishes across adjacent coral reef and seagrass habitats at Carrie Bow Cay, Belize. At least 16 decapod and seven fish species were associated with anemones across both habitats, including several previously undocumented associations. While overall anemone-associate richness did not differ between habitats, seagrass anemones had the greatest mean abundance and diversity of both decapod and fish associates. This suggests that the importance of anemones as microhabitat reflected broader benthic complexity and shelter availability, with species aggregating on sea anemones when access to alternative shelter, such as corals, was limited. Patterns of associate distributions on anemones were also highly structured, in terms of both associate and anemone species, with these patterns likely reflecting a combination of associate specialization, intraspecific competition, and anemone morphology and toxicity.

Much scope for further study on the marine carideans of Indian waters still exists and many species must certainly remain to be discovered. Although, the recent checklist on prawn fauna of Indian waters reports 285 species of caridean shrimps (including fresh water forms) (Radhakrishnan et al, 2012). With this, the present study also contributes another report on the documentation of six species of caridean shrimps from the Gulf of Mannar and Lakshadweep waters of In- dian peninsula. Out of six species Ancylomenes magnificus (Bruce), Periclimenes soror Nobili, Stegopontonia commen- salis Nobili, Gnathophyllum americanum Guerin Meneville and Gnathophylloides mineri Schmitt are new to the Indian fauna.

    Molecular phylogenetic analysis of Pederson’s cleaner shrimp (Ancylomenes pedersoni) supports classification of Bermudan population as separate species (Ancylomenes anthophilus) Honors Research Thesis Presented in Partial Fulfillment of the Requirements for graduation “with Honors Research Distinction in Evolution and Ecology” in the undergraduate colleges of The Ohio State University By Spencer Palombit The Ohio State University April 2014 Project Advisors: Dr. Marymegan Daly, Department of Ecology, Evolution, and Organismal Biology, Benjamin Titus (PhD Student), Department of Ecology, Evolution, and Organismal Biology 1 Abstract Caribbean populations of the Pederson's cleaner shrimp (Ancylomenes pedersoni) have undergone increasing phylogenetic scrutiny, especially in Bermuda and the Florida Keys. Until now, however, no research using molecular data has been conducted to evaluate whether these populations constitute separate species. In this study, phylogenetic analyses of Pederson shrimp from the Florida Keys and Bermuda were performed using multiple loci: mitochondrial genes encoding cytochrome c oxidase subunit I (COI) and 16S-rDNA, and nuclear genes encoding the enzyme enolase. The phylogenetic networks estimated using mitochondrial DNA strongly suggest that the populations constitute three reciprocally monophyletic groups, one endemic to Bermuda, and two sympatric clades in the Florida Keys. The insights gained from this study will be instrumental in resolving the contested status of the Pederson’s cleaner shrimp species, and will contribute to a fuller understanding of Caribbean species diversity. 2 Introduction Species delimitation is one of the prime goals of phylogenetics, but the issue of what constitutes a species has been a problematic and disputed question (Mayden 1997; de Queiroz 1998). Many definitions of the proper classification of a species have persisted; phylogenetic, biological, character-based, and numerous other species concepts are considered competing and valid possibilities (de Queiroz 2007; Hey 2006).
