Breeding Dispersal of Baltic Dunlins Is Not an Adaptive Response to Unpredictable Nest Flooding

open access: yesAnimal Conservation, EarlyView.
Flood‐related nest losses of the Baltic dunlin (Calidris alpina schinzii) have drastically increased over the past two decades. Using 20 years of reproductive data from 184 individuals, we found that between‐year and within‐site dispersal tended to increase following nest failure in males.

Procurement of Senonian Flint for Bladelets Production at the Early PPNB Site of Nahal Zahal in the Northern Negev Established for the First Time Using Chemical Composition Analysis

open access: yesArchaeometry, EarlyView.
ABSTRACT The hypotheses of Senonian flint to be a prime source of prehistoric “chalcedony” flint artefacts from the Negev Desert (Israel) was not investigated in detail thus far. By combining trace‐element profiling with statistical interpretation, ten flint items from Nahal Zahal, an Early Pre‐Pottery Neolithic B site in the northern Negev, were ...

The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

open access: yesActa Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Egg Chorion Morphology and Egg‐Laying Behaviour of Backswimmer Notonecta viridis Delcourt, 1909 (Heteroptera: Nepomorpha: Notonectidae)

open access: yesActa Zoologica, EarlyView.
ABSTRACT In this study, the egg‐laying behaviour and chorionic morphology of the eggs of the backswimmer Notonecta viridis Delcourt, 1909 (Heteroptera: Notonectidae) were described in detail using stereo, light and electron microscopy. Female N. viridis lays its eggs individually, horizontally attached to the surface. Eggs are elliptical, approximately

Optimization of Eggshell Calcium Use for Improving the Physical Quality of Whey Protein Isolate-based Edible Films [PDF]

open access: yesBIO Web of Conferences
Edible films based on biopolymers are increasingly popular as environmentally friendly and functional food packaging alternatives. One approach to improving the physical properties of edible films is by incorporating calcium derived from eggshell waste ...

Rearing Istocheta aldrichi (Diptera: Tachinidae) From Field‐Collected Japanese Beetles (Popillia japonica): 1. Methods to Improve Insect Collection and Parasitoid Pupariation

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
We describe methods for collecting and rearing the tachinid parasitoid Istocheta aldrichi from parasitized Japanese beetle adults. Hosts can be collected by hand and reared in the laboratory, or by using modified trap containers with added plant material and substrate to provide suitable conditions for I.

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

open access: yesThe FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

Beyond the specimen: rethinking ornithological collecting in a changing world

open access: yesIbis, EarlyView.
Natural history collections underpin a wide range of ornithological research, yet the context in which they operate is rapidly changing. Advances in genomics, digitization and analytical approaches are transforming what can be learned from specimens, while accelerating environmental change is increasing the need for temporally explicit, integrative ...
