Fertility Decline in Malawi: A Decomposition Analysis

Populasi
Fertility in Malawi has been declining since the late 1980s. Total Fertility Rate is reported to have declined by 1.1 children per woman from 5.7 in 2010 to 4.6 in 2015. This reduction indicates a continuing rapid decline in fertility in the country.

Using Landsat Satellite Imagery to Investigate Spatial and Temporal Variation in Life History Traits in a Long‐Term Study Population of Superb Fairy‐Wrens Malurus cyaneus

Ecology and Evolution, Volume 16, Issue 6, June 2026.
We used 27 years of data from an insectivorous passerine in southeastern Australia, the superb fairy‐wren Malurus cyaneus, to assess how climate variation influences vegetation productivity and, indirectly, reproduction and survival via potential trophic interactions.

Impact of Female Mating Status on Male Courtship Behaviour in a Sexually Cannibalistic New Zealand Fishing Spider

Ethology, Volume 132, Issue 6, Page 373-384, June 2026.
Scoring of male courtship behaviour in Dolomedes minor revealed no effect of female mating status on courtship duration or sequence structure, but males delayed the initiation of courtship when encountering previously mated females. ABSTRACT The evolution of male courtship rituals has traditionally been attributed to female mate selection, but may also

Genome‐wide and gene‐specific DNA methylation across developmental stages in Pogonomyrmex californicus: A socially polymorphic ant

Insect Molecular Biology, Volume 35, Issue 3, Page 232-245, June 2026.
Comparison between developmental stages (larvae, pupae, worker) in Pogonomyrmex californicus revealed significant stage‐specific differences in Gene Body Methylated frequencies. Methylation sites were highly correlated between WGBS and ONT in P. californicus Genome‐wide methylation was low (~3%) and highly clustered within gene bodies (GBM), especially

DEMOGRAPHIC CHARACTERISTICS OF THE BAĆINA PARISH (1870. – 1880.) [PDF]

Hum, 2013
Both components of the natural movement of the population are on the transition from high to low. The average annual birth rate ranges at the level of 29.60 ‰ and thus found itself at the beginning of the demographic transition, fertility, and the ...

Detection of Leptospira in cane toads (Rhinella jimi) from urban and rural Paraíba, Brazil

Veterinary Record, Volume 198, Issue 10, Page e461-e470, 16/23 May 2026.
Abstract Background Leptospirosis is a significant zoonosis in tropical regions, where poor sanitation and favourable climate aid its spread. Synanthropic animals such as the cane toad (Rhinella jimi), which share environments with both people and wild and domestic animals, may harbour Leptospira and contribute to urban and rural transmission cycles ...

Solitary Confinement: Surprising Post‐Copulatory Behaviour of an Australian Species of Wishbone Spider (Mygalomorphae: Anamidae: Aname)

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Araneomorph spiders are regarded as a model group for sexual selection studies, while the mating system of mygalomorph spiders remains largely unknown. We here report on the mating behaviour of an Australian wishbone spider species, involving a novel post‐copulatory behaviour for mygalomorph spiders (‘burrow plugging’).

Genetic Divergence in the Absence of Strong Ecological Differences Between Coexisting White and Common Atlantic Marine Stickleback

Ecology and Evolution, Volume 16, Issue 5, May 2026.
We examined whether the “white” threespine stickleback of Nova Scotia represents a nascent species distinct from sympatric common marine sticklebacks. Genomic analyses revealed that whites form a unique genetic cluster with low but widespread divergence across the genome despite evidence of gene flow, while morphometric and isotopic data indicated ...

Habitat‐Driven Sexual Dimorphism in Triplophysa strauchii Between Oxbow Lake and Stream: A Geometric Morphometric Analysis

Ecology and Evolution, Volume 16, Issue 5, May 2026.
The combined effects of sexual selection and natural selection give rise to sexual dimorphism in operculum and eye morphology of T. strauchii across the two river basins. And our study reveal the fine‐scale responses of fish sexual dimorphism to diverse selective forces.

Phenology of migrating game birds in Italy based on citizen science data

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Studying the timing of the seasonal movements of migratory birds, known as migration phenology, is crucial for managing and conserving migratory bird populations. This is particularly important for migratory game bird populations in Europe because, according to the EU, migratory birds should not be hunted during their breeding season or during return ...
