Streptocephalus diversity in Myanmar, with description of a new species (Branchiopoda, Anostraca)
ZooKeys, 2018 The diversity of anostracans in Myanmar is poorly known. A series of biodiversity surveys had been conducted in Myanmar, and two species of Streptocephalus were collected in the central dry zone.

Ornaments or offspring? Female sticklebacks (Gasterosteus aculeatus L.) trade off carotenoids between spines and eggs [PDF]
Journal of Evolutionary Biology, 2006 Abstract Hypotheses and models to explain female ornaments often assume that the elaborated traits are condition dependent; nevertheless, few empirical studies have addressed this topic. We studied a population of three-spined sticklebacks (Gasterosteus aculeatus) in which the females have conspicuous, carotenoid-based red coloration to ...

Transcriptome Analysis of Tailfins From Grass-Goldfish And Egg-Goldfish to Identify Genes Involved in Artificial Selection for Ornamental Purposes [PDF]
, 2021 Abstract Goldfish, one of the first animals domesticated for ornamental purposes, experience huge morphological variation, of which the number changes in tailfins and the loss of dorsal fins is the most impressive due to their important functions in fish.

The Auk, 2020 Lay Summary• There is equivocal support for direct associations between maternal quality and deposition of protoporphyrin pigmentation (dark spots and blotches) in avian eggshells.• Research on protoporphyrin eggshell pigmentation has primarily focused on a single avian order (Passeriformes).• We examined associations of protoporphyrin-based eggshell ...

Comparing the egg ultrastructure of three Psorophora ferox (Diptera: Culicidae) populations
Brazilian Journal of Biology, 2017 Characterising the external morphology of mosquito eggs is important, since it facilitates the identification of material from breeding sites and contributes to the understanding of species biology and group systematics.

Journal of Limnology, 2014 Studying the species distribution of Limnadiidae, a family of crustaceans, in environments favourable to their growth and reproduction is made difficult by their extremely short life cycle and the transient existence of adult forms.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution
Advanced Science, EarlyView.Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...
