Sea Spider development: How the encysting Anoplodactylus eroticus matures from a buoyant nymph to a grounded adult [PDF]

arXiv, 2013
In order to understand how animals evolved over time, biologists must learn how their body parts form during their development. The following is a detailed description of how one species of sea spider transforms from a hatchling to an 8-legged adult. Pycnogonids, or sea spiders, comprise a primitive lineage of arthropods.

Transcriptional response in larvae of the generalist fruit fly Anastrepha obliqua feeding on three different tropical host plants

Entomologia Experimentalis et Applicata, EarlyView.
We investigated the molecular basis of host switching by the phytophagous West Indian fruit fly (A. obliqua). Third‐instar larvae showed differential gene expression according to host plants: red mombin, mango, and carambola. The main gene categories differentially expressed were digestion, detoxification, and gene regulators.

Controlled Ghost Fishing: Effects of Soaking Times and Mesh Sizes on Catchability in Trammel Net Fisheries

Fisheries Management and Ecology, EarlyView.
ABSTRACT Trammel nets are used with extended soaking times to increase the catching efficiency for demersal fish in commercial fishing. Long soaking time causes deterioration or damage to species caught in the first days. Effects of soaking time were investigated with 36‐mm, 42‐mm, and 46‐mm mesh sizes soaked over 1, 3, 5, and 7 days on target, non ...

Feeding ecology in sea spiders (Arthropoda: Pycnogonida): what do we know?

Frontiers in Zoology, 2018
Sea spiders (Pycnogonida) are a widespread and phylogenetically important group of marine arthropods. However, their biology remains understudied, and detailed information about their feeding ecology is difficult to find.

The use of collembolans (Collembola: Arthropoda) as a biological indicator in comparison of different land use and seasons in Karabük

Turkish Journal of Forestry, 2020
Land use types and seasonal conditions are effective factors on soil properties and soil quality. One of the criteria of soil quality is biological indicators.

Identifying conservation hotspots and assessing species commonness and rarity: Baseline arthropod diversity in German nature reserves via national Malaise trap monitoring

Insect Conservation and Diversity, EarlyView.
Conducted a year‐long Malaise trap monitoring study across Germany, revealing 14,445 OTUs, including 8,589 assigned species, highlighting extensive small‐scale and largely undescribed diversity. Identified 17 invasive species, five of which are new records for Germany, underscoring the need for continuous monitoring to manage invasive species ...

RNA profile diversity across arthropoda: guidelines, methodological artifacts, and expected outcomes

Biology Methods and Protocols, 2018
High-quality RNA is an important precursor for high-throughput RNA sequencing (RNAseq) and subsequent analyses. However, the primary metric used to assess RNA quality, the RNA Integrity Number (RIN), was developed based on model bacterial and vertebrate ...

Tree hollow parameters and their effects on saproxylic arthropod diversity: A multi‐taxon approach

Insect Conservation and Diversity, EarlyView.
Tree hollows are keystone structures for biodiversity in forests and support saproxylic arthropods but are declining in central Europe due to intensive forest management, threatening these invertebrate communities. Research using DNA metabarcoding examined non‐beetle arthropods in 40 beech tree hollows, exploring their habitat requirements in southern ...

The checklist of Collembola (Hexapoda, Arthropoda) from west of Iran

Journal of insect biodiversity and systematics, 2019
. In this study, the list of Collembola from west of Iran and collection information such as study site, habitats, e.g. soils, grasslands, leaf-litter, vegetation, snowfields, etc., and collectors has been presented between years 2013-3018. Moreover some

Identification of orb-web spider species and their food source through environmental DNA analysis

Journal of Ecology and Environment
Spiders play a vital role in agricultural ecosystems by capturing and preying on small insects, thereby controlling the pests around crops. However, without directly collecting the specimen, it is challenging to accurately determine the species of the ...
