Phylogeography of the supralittoral isopod Ligia occidentalis around the Point Conception marine biogeographical boundary
TLDR
This work examines the effects of the PC boundary and other potential dispersal barriers on phylogeographical patterns in the rocky supralittoral isopod Ligia occidentalis, which has a limited dispersal potential, its distribution spans the PC region, and it exhibits high levels of allopatric genetic differentiation south of PC.

Genetic diversity of the pelagic harpacticoid copepod Macrosetella gracilis on colonies of the cyanobacterium Trichodesmium spp.
TLDR
The pelagic existence of M. gracilis has led to less phylogenetic structuring than found in other species of harpacticoid copepods, illustrating the evolutionary significance of specialization on a floating sub- strate in this copepod.

Association of the copepod Macrosetella gracilis with the cyanobacterium Trichodesmium spp. in the North Pacific Gyre
TLDR
Natural abundance of stable isotopes in copepod tissue from field samples suggested that the diet of M. gracilis was not predominately composed of Trichodesmium spp.

Genetic diversity and structure in the annual vernal pool endemic Limnanthes vinculans Ornduff (Limnanthaceae): implications of breeding system and restoration practices
TLDR
It is concluded that breeding system and natural, anthropogenic, and temporal seed inputs combined to influence the patterns of genetic variation found in natural and created populations informing conservation of the species.

Sea-land transitions in isopods: pattern of symbiont distribution in two species of intertidal isopods Ligia pallasii and Ligia occidentalis in the Eastern Pacific
  • R. Eberl
  • Environmental Science, Biology
    Symbiosis
  • 31 March 2010
TLDR
Mycoplasma-like bacteria (Firmicutes), related to symbionts described from terrestrial isopods, were the most common bacteria present in both host species and there was greater overall microbial diversity in Ligia pallasii compared with L. occidentalis.

Mycorrhizal association with native and invasive cordgrass Spartina spp. in San Francisco Bay, ­California
  • R. Eberl
  • Environmental Science
  • 29 November 2011
For the first time, hybrids of Spartina al- terniflora × foliosa are reported to form mycorrhizal associations. This is important in light of the invasion dynamics within San Francisco Bay—where…

Sea star wasting disease demography and etiology in the brooding sea star Leptasterias spp.
TLDR
Examining Leptasterias populations at sites along the California coast and documenting abundance changes coincident with recent Pacific coast SSWD found that magnesium chloride (MgCl2) slowed the progression of physical deterioration related to SSWD when applied to sea stars in the laboratory, suggesting that MgCl1 may prolong the survival of diseased individuals.

Distribution, habitat and food preferences of sympatric high intertidal isopod species Ligia occidentalis and Ligia pallasii (Ligiidae: Oniscidea)
  • R. Eberl
  • Environmental Science
  • 24 July 2012
TLDR
A survey along the Eastern Pacific coast indicated species-specific site preferences as evidenced by a mosaic pattern of distribution with few sites of co-occurrence, and feeding experiments did not indicate any significant differences in diets.

Phylogeography of the high intertidal isopod Ligia pallasii Brandt, 1833 (Isopoda: Oniscidea) from the Aleutian Islands to Monterey Bay
TLDR
The observed pattern of lower genetic divergence at higher latitudes suggests that processes (gene flow, selection, and drift) that lead to genetic divergence may vary as a function of latitude.

Bacterial communities in the hepatopancreas of different isopod species
  • R. Eberl
  • Biology, Environmental Science
  • 2008
TLDR
Clone libraries from some but not all species in this study included sequences closely related to previously described isopod symbionts with the majority clustering around Candidatus Hepatoplasma crinochetorum (Firmicutes, Mollicutes).
