Insect Molecular Biology, EarlyView.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

Fertility Decline in Malawi: A Decomposition Analysis
PopulasiFertility 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.

Journal of Fish Biology, EarlyView.Abstract During snorkelling near Frøya, central Norway, on 6 October 2025, a pair of adult lumpsuckers (Cyclopterus lumpus) was observed engaged in apparent prespawning behaviour in shallow kelp habitat. Such activity is surprising, as the species is mainly considered a spring spawner throughout the eastern Atlantic and is the focus of a targeted ...

Was malthus right? a var analysis of economic and demographic interactions in pre-industrial England [PDF]
, 2006 This paper shows that the interaction between economic and demographic variables in England before the onset of modern economic growth did not fit some crucial assumptions of the Malthusian model. I estimated a vector autoregression for data on fertility,

Tijdschrift voor Economische en Sociale Geografie, EarlyView.Abstract Several theories have been proposed to explain the family changes that have occurred in Europe since the mid‐1960s. It is often assumed that as these changes occurred simultaneously; they have a common origin and represent the same demographic shift.

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.ABSTRACT Three‐spined sticklebacks (Gasterosteus aculeatus) have become dominant in many Baltic Sea coastal fish assemblages, yet life‐stage‐specific habitat use remains poorly understood. We surveyed shallow water habitats along the coast of Gotland, Sweden, to examine how juvenile and adult stickleback abundances relate to variables such as submersed

Biotropica, Volume 58, Issue 2, March 2026.Peruvian frogs underwent a climate‐driven range expansion into deglaciating mountains, exposing themselves and their fungal pathogen Batrachochytrium dendrobatidis (Bd) to challenging new thermal environments. Bd has dispersed extensively in these new habitats, and elevation may mediate the apparent sublethal impacts of infection for frogs.
