Evolutionary responses of marine invertebrates to insular isolation in Galapagos [PDF]
, 2009 I examine the natural barriers to distribution and colonization that have shaped the Galapagos marine invertebrate biota. While diversity is high for some groups, such as hydroids and bryozoans, it is low for many others. Porcelain crabs and molluscs are

Detection of Salinity by the Lobster, Homarus americanus [PDF]
, 2001 Changes in the heart rates of lobsters (Homarus americanus) were used as an indicator that the animals were capable of sensing a reduction in the salinity of the ambient seawater.

Investigating diet as the source of tetrodotoxin in Pleurobranchaea maculata [PDF]
, 2014 The origin of tetrodotoxin (TTX) is highly debated; researchers have postulated either an endogenous or exogenous source with the host accumulating TTX symbiotically or via food chain transmission.

Ecography, Volume 2025, Issue 10, October 2025.The core–periphery hypothesis (CPH) predicts that genetic diversity is greatest at the centre and lowest at the edges of a species' distribution because genetic diversity is a function of a species' abundance, which is also expected to be greatest at the centre and lowest at the edges of the distribution. Variants of the CPH include the ‘Ramped North' (

The History and Literature of America's Oysters [PDF]
, 1996 Historically, America's use and enjoyment of the oyster extend far back into prehistoric times. The Native Americans often utilized oysters, more intensively in some areas than in others, and, at least in some areas of the Caribbean and Pacific coast ...

Advancing Seabird Diet Studies Through Buccal Swabbing for DNA Metabarcoding
Ecology and Evolution, Volume 15, Issue 7, July 2025.Determining the diet of wide‐ranging, pelagic seabirds is challenging. In this study, we investigated buccal swabbing and DNA metabarcoding to describe the diet of Manx shearwaters (Puffinus puffinus) and northern fulmars (Fulmarus glacialis). We reveal a potential dietary specialism in shearwaters and highlight the continued importance of fishery ...

Classification, Biodiversity and Conservation of Marine Commercial Crabs of India [PDF]
, 2017 One of the best known and most intensely studied groups is the true crabs of the infraorder Brachyura. Brachyuran crabs belong to the Order Decapoda, the most diverse group of crustaceans alive today (Ng et al., 2008).

Food web positioning of a recent coloniser: the North American Harris mud crab Rhithropanopeus harrisii (Gould, 1841) in the northern Baltic Sea [PDF]
, 2015 Identifying resource use and functional traits of non-indigenous species are promising means to increase the ability to predict ecological consequences of invasions.

Oikos, Volume 2025, Issue 7, July 2025.Habitat complexity (HC) promotes species richness and abundance. Aquatic environments are faced with intense pressures that threaten the 3D structure of the seafloor, with cascading effects on ecosystem functioning and biodiversity. Maerl or rhodolith beds are marine biogenic habitats created by few species of free‐living non‐geniculate coralline algae

Cold-Induced Vasodilation and Vasoconstriction in the Finger Of Tropical and Temperate Indigenes [PDF]
, 2013 While heat acclimatization reflects the development of heat tolerance, it may weaken an ability to tolerate cold. The purpose of this study was to explore cold-induced vasodilation (CIVD) responses in the finger of tropical indigenes during finger cold ...
