Constrained body shape among highly genetically divergent allopatric lineages of the supralittoral isopod Ligia occidentalis (Oniscidea). [PDF]
Ecol Evol, 2016 The rocky supralittoral isopod Ligia occidentalis sensu lato has a broad distribution in the eastern Pacific, where multiple allopatric genetically divergent lineages occur, which are exposed to marked environmental differences. Using geometric morphometrics, we detected statistically significant differences in body shape among highly divergent ...

Assessing the current state of ecological connectivity in a large marine protected area system
Conservation Biology, Volume 35, Issue 2, Page 699-710, April 2021., 2021 Abstract The establishment of marine protected areas (MPAs) is a critical step in ensuring the continued persistence of marine biodiversity. Although the area protected in MPAs is growing, the movement of individuals (or larvae) among MPAs, termed connectivity, has only recently been included as an objective of many MPAs.

The researches of the aquatic biological resources of Kamchatka and the North-West Part of the Pacific Ocean, 2022 The state of the aggregation of Pacific oyster Crassostrea gigas (Thunberg, 1793) in the Losos Bight (Aniva Bay) in 2013–2020 was assessed. For now, this aggregation has been in depression as a result of intense fishing. The abundance of the aggregation of commercial individuals (shell height >120 mm) was poor two recent years.

Factors influencing occupancy and density of salt marsh songbirds in northeast Florida
Journal of Field Ornithology, Volume 91, Issue 2, Page 156-169, June 2020., 2020 Abstract Salt marshes and the organisms that depend on them are subject to a variety of anthropogenic threats. In Florida, Worthington’s Marsh Wrens (Cistothorus palustris griseus) and MacGillivray’s Seaside Sparrows (Ammospiza maritima macgillivraii) are species of concern that inhabit a small, narrow range of salt marsh in the northeastern corner of ...
