Assessing the effectiveness of Sri Lankan marine protected areas: Challenges and recommendations
Conservation Science and Practice, Volume 8, Issue 10, October 2026.We evaluated the biodiversity conservation effectiveness of 32 zones of Sri Lankan marine protected areas (MPA) and found that most are currently insufficiently protected. Threats to MPAs were not uniform, with harmful dredging/dumping, anchoring, fishing, and non‐extractive activities identified as major pressures affecting different sets of MPAs.

Evolutionary Applications, Volume 19, Issue 10, October 2026.ABSTRACT Forecasting extinction risk from genomic data is challenging because of interactions among environment, demography, and genomic erosion. Here, we use known outcomes from forward simulations as a proof‐of‐concept study to test whether machine‐learning (ML) models can discriminate relative extinction risk and recovery potential from genomic ...

Global Ecology and Biogeography, Volume 35, Issue 10, October 2026.ABSTRACT Aim The introduction of non‐native species to native ecological communities by humans is a major driver of global biodiversity change. Studying how species introductions influence interacting species is essential to understanding possible functional consequences of global change because biotic interactions are ecologically crucial.

Ibis, Volume 168, Issue 4, Page 1364-1377, October 2026.Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

On the geometry of WDVV equations and their Hamiltonian formalism in arbitrary dimension
Journal of the London Mathematical Society, Volume 114, Issue 4, October 2026.Abstract It is known that in low dimensions Witten–Dijkgraaf–Verlinde–Verlinde (WDVV) equations can be rewritten as commuting quasilinear bi‐Hamiltonian systems. We extend some of these results to arbitrary dimension N$N$ and arbitrary scalar product η$\eta$.

Pigeon Rotavirus A as the cause of systemic infection in juvenile pigeons (young pigeon disease)
Tierärztliche Praxis Ausgabe K: Kleintiere / Heimtiere, 2022AbstractRecent investigations suggested pigeon associated Rotavirus Typ A genotype G18P[17] (RVA) as a causative agent of the classical ‘young pigeon disease’ (YPD). YPD was first described in the late 1980 s as an acute, mainly seasonally recurring disorder of mostly juvenile domestic pigeons (Columba livia) with clinical signs such as anorexia ...

THE spectacular hereditary trait of backward somersaulting by Tumbler pigeons has been known since 1600 AD1 and was described by Darwin as “… one of the most remarkable inherited habits or instincts ever recorded …”2. The potentially important physiological mechanism of tumbling is unknown, largely because the extreme rapidity of the somersaulting ...

Seminoma has been reported to have occurred in 2 cockerels (1), 22 budgerigars, a Jardine warbler, an Amazon green parrot, and a collared turtle dove (3). This tumor is most commonly seen in various species of pet birds five years of age or older. Lethargy, anorexia, dyspnea, and loose droppings are the most frequently reported signs.
