  Seasonal Variation in Whole-Body Elemental Concentrations and Excreta Production of a Riparian Orb-Weaving Spider (Larinioides cornutus) ABSTRACT Predators influence nutrient cycling by assimilating elements from their prey and returning nutrients to ecosystems via excretion and discarded prey remains. However, seasonal variation in the contribution of predators to nutrient cycling remains poorly understood, particularly for terrestrial arthropod predators such as spiders. We examined temporal variation in whole-body elemental concentrations, excreta C and N concentrations, and cumulative excreta output in a riparian orb-weaving spider ( Larinioides cornutus ) across the growing season of 2024. Adult females were collected across seven sampling periods spanning mid-June to early October, and whole-body concentrations of macronutrients (carbon [C], nitrogen [N], phosphorus [P]) and multiple trace elements were quantified. Whole-body N and P concentrations, and several trace elemen...

Studies on spider nomenclature II: a synonymy and misidentification in Asian Pholcus Walckenaer, 1805 (Araneae: Pholcidae)

Abstract
In this work, the synonymy suggested by Yao, Tavano & Li (2013) is confirmed and proposed formally. Furthermore, the material tentatively identified by Huber (2011) as P. gracillimus is determined to be a new species, matching no species known at the time of Huber (2011), nor any of the Pholcus species described after 2011. It is thus formally described herein and nomenclatural implications for the naming of informal species groups in Pholcus is given.
