Weaponry Investment in the Socially Monogamous Snapping Shrimp Alpheus brasileiro (Decapoda: Alpheidae)

Acta Zoologica, EarlyView.
ABSTRACT Weapons are morphological structures used by animals in various contexts, especially in intra‐specific contests and visual displays. In snapping shrimps of the genus Alpheus, particularly the monogamous species Alpheus brasileiro, both sexes bear enlarged chelipeds, potentially conferring advantages in mate competition or territorial defence ...

The functional roles of herbivores in the rocky intertidal systems in Chile: A review of food preferences and consumptive effects Los roles funcionales de los herbívoros en sistemas intermareales rocosos en Chile: Una revisión de las preferencias alimenticias y efectos de consumo

Revista Chilena de Historia Natural, 2011
This paper reviews recent knowledge about the functional roles that herbivores have in intertidal communities in Chile. Specifically, I review field and laboratory studies dealing with the food preferences of herbivores, the responses of algae to ...

Marine sediment infauna‐based environmental assessment using metabarcoding identifies potential impact indicator species

Environmental DNA
Developing large‐scale monitoring strategies for marine habitats with appropriate temporal and spatial resolution is challenging logistically and economically.

First Insights on Photoreceptor Organ Ultrastructure in Marine Chaetonotida (Gastrotricha): Species of Xenotrichula and Draculiciteria (Xenotrichulidae)

Acta Zoologica, EarlyView.
ABSTRACT Marine gastrotrichs inhabit sediments with limited available light, yet evidence suggests that photoreceptor organs are present throughout the phylum Gastrotricha. Here, we confirm this proposition with ultrastructural descriptions of photoreceptive organs in two species of Xenotrichulidae (Order Chaetonotida) that lack pigmented ocelli ...

Extremely low biodiversity Arctic intertidal habitats as sentinels for environmental change

Frontiers in Marine Science
The Arctic is undergoing dramatic changes, including an unprecedented decline in sea ice. Previous studies have shown the severe structuring impact of sea ice scour upon polar intertidal communities.

Truncated drumlins and their implication for past sea level reconstructions

Boreas, EarlyView.
Coastal erosion of glacigenic sediments, particularly in the form of retreating drumlin bluffs, is a key process in paraglacial landscape evolution during periods of relative sea‐level (RSL) rise. As marine transgression reworks formerly subaerial glacial terrains, drumlins act as discrete sediment sources generating characteristic erosional and ...

Struktur Komunitas Invertebrata Asosiasi Sampah Laut Organik di Pesisir Kabupaten Malang, Jawa Timur

Jurnal Ilmu Lingkungan
Invertebrata laut umumnya ditemukan di wilayah perairan laut terutama area intertidal. Namun, seiring dengan kebutuhan akan makanan dan tempat berlindung, invertebrata laut juga dapat ditemukan di sampah laut organik di daerah pesisir.

Clues of ancient incomplete lineage sorting during bivalve evolution undermine support for Heterodonta

Cladistics, EarlyView.
Abstract A long‐standing challenge in phylogenomics has been the resolution of relationships originated from ancient radiations. In these cases, phenomena such as incomplete lineage sorting can increase the support for conflicting resolutions. Most of the diversity in the Class Bivalvia originated during an Ordovician radiation; indeed, several deep ...

When and why to give shorebirds a head start

Conservation Biology, EarlyView.
Abstract Headstarting is a translocation technique involving the hatching or rearing of wild eggs or young in captivity and the release of those individuals back to the wild at or before independence. It has been trialed as a conservation intervention for shorebirds over recent decades to improve the population trend of target populations by increasing

Genealogical approaches to the temporal origins of the Central American gap: Speciation and divergence in Pacific Chthamalus (Sessilia: Chthamalidae)

Revista de Biología Tropical, 2013
A large section of the tropical Eastern Pacific coastline is nearly devoid of reef or consolidated habitat, and is known as the Central American Gap as it is associated with a biogeographic transition in fish and invertebrate species.
