Are standard aquatic test species and methods adequate surrogates for use in environmental risk assessment of pesticides in tropical environments?

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 202-212, January 2023., 2023
Abstract In regulatory risk assessment, surrogate species of fish, aquatic invertebrates, and primary producers are tested to assess toxicity and subsequently the risk of pesticides to freshwater biota. This study evaluates whether the standard, surrogate test species (mostly temperate in latitudinal distribution) used in many parts of the world are ...

The secret world of shrimps: polarisation vision at its best [PDF]

PLoS ONE 3, e2190 (2008), 2008
Animal vision spans a great range of complexity, with systems evolving to detect variations in optical intensity, distribution, colour, and polarisation. Polarisation vision systems studied to date detect one to four channels of linear polarisation, combining them in opponent pairs to provide intensity-independent operation.

Thyroid‐like hormone signaling in invertebrates and its potential role in initial screening of thyroid hormone system disrupting chemicals

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 63-82, January 2023., 2023
Abstract This review examines the presence and evolution of thyroid‐like systems in selected aquatic invertebrates to determine the potential use of these organisms in screens for vertebrate thyroid hormone axis disrupting chemicals (THADCs). Such a screen might support the phasing out of some vertebrate testing.

History and sensitivity comparison of two standard whole-sediment toxicity tests with crustaceans : the amphipod Hyalella azteca and the ostracod Heterocypris incongruens microbiotest [PDF]

, 2015
The review first details the development of the test procedures with Hyalella azteca which historically emerged as one of the recommended test species for whole-sediment assays and its gradual standardization and endorsement by national and international

Charting the landscape of the environmental exposome

iMeta, Volume 1, Issue 4, December 2022., 2022
We describe the biological and chemical components of the environmental exposomes in three major environmental matrices that are highly relevant to human and social‐economical health—air, soil, and water. We discuss how different exposome components can interact with each other. Finally, we propose a list of outstanding challenges to be tackled to push

Historical Connectivity and Demography of the Ferocious Reef Crab, Eriphia ferox (Crustacea; Eriphiidae), Demonstrate That Taoyuan Algal Reef Is an Essential Population Source Along the East Taiwan Strait

Frontiers in Marine Science, 2022
The east Taiwan Strait is largely fringed by sandy and muddy habitats. However, a massive algal reef made of crustose coralline algae has been found along the coast off Taoyuan city in northwestern Taiwan.

Reliability and robustness of oscillations in some slow-fast chaotic systems [PDF]

arXiv, 2022
A variety of nonlinear models of biological systems generate complex chaotic behaviors that contrast with biological homeostasis, the observation that many biological systems prove remarkably robust in the face of changing external or internal conditions. Motivated by the subtle dynamics of cell activity in a crustacean central pattern generator (CPG),

Novel RNA viruses in oysters revealed by virome

iMeta, Volume 1, Issue 4, December 2022., 2022
Eighteen novel RNA viruses were found in Crassostrea hongkongensis. Phylogenic analysis shows evidence of recombination between major genes of viruses. Picobirnaviruses are ubiquitous and abundant in oysters.

Extreme morphologies of mantis shrimp larvae [PDF]

, 2016
Larvae of stomatopods (mantis shrimps) are generally categorized into four larval types: antizoea, pseudozoea (both representing early larval stages), alima and erichthus (the latter two representing later larval stages).
