Butterfly and moth habitat specialisation changes along an elevational gradient of tropical forests on Mount Cameroon

Oikos, Volume 2026, Issue 4, April 2026.
Niche breadth, reflecting the range of environmental conditions or resources a species can exploit, influences its distribution, persistence, vulnerability to environmental change, and interspecific interactions. The elevational niche‐breadth hypothesis predicts broader ecological niches at higher elevations due to increased environmental stress and ...

Phylogeny of subtribe Gonolobinae (Apocynaceae‐Asclepiadoideae) based on molecular and morphological data with a revised generic classification

TAXON, Volume 75, Issue 2, April 2026.
Abstract The presently most densely sampled molecular phylogeny of the widespread New World subtribe Gonolobinae is presented, including about 35% of the ca. 520 species. Sampling focused on an even representation of the three main areas of total Gonolobinae distribution, South America, Central/North America, and the West Indian Islands, and the ...

Species richness and community composition of sphingid moths (Lepidoptera: Sphingidae) along an elevational gradient in southeast Peru [PDF]

Zoologia (Curitiba), 2019
A clear low-elevation skewed unimodal richness pattern is presented for hawkmoths in Southeast Peru. Several hypotheses offer plausible explanations for such a distribution.

Is bee‐avoidance by bird‐pollinated flowers driven by nectar robbing in Erica?

Functional Ecology, Volume 40, Issue 4, Page 1046-1060, April 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Nectar robbing (consuming nectar from a perforated flower without pollinating) generally negatively affects plant fecundity, and plants exhibit multiple mechanisms in defence.

Laplace’s Demon and the Adventures of His Apprentices [PDF]

, 2014
The sensitive dependence on initial conditions (SDIC) associated with nonlinear models imposes limitations on the models’ predictive power. We draw attention to an additional limitation than has been under-appreciated, namely structural model error (SME).

Recruitment of Native Pollinators and Dispersers by Lonicera japonica May Facilitate Its Invasion and Its Potential Threat to Local Biodiversity

Austral Ecology, Volume 51, Issue 4, April 2026.
ABSTRACT Lonicera japonica is a plant native to Asia that has been widely used in landscaping as an ornamental plant, but has escaped cultivation and become invasive in several countries. This study examined the reproductive phenology, pollinator attraction, and potential dispersal mechanisms of L.

Nocturnal Lepidopterans as Essential Pollinators of Aspidosperma pyrifolium (Apocynaceae), a Keystone Tree in the Caatinga Dry Forest

Journal of Applied Entomology, Volume 150, Issue 3, Page 351-363, April 2026.
ABSTRACT Pollination is a key ecosystem service, yet most studies focus on diurnal interactions, often overlooking nocturnal pollinators such as hawkmoths and settling moths. In arid environments, nocturnal pollination plays a crucial role in maintaining native plant species of high biocultural value, as seen in the Caatinga dry forest.

Dissociating the effect of disruptive colouration on localisation and identification of camouflaged targets [PDF]

, 2018
Disruptive camouflage features contrasting areas of pigmentation across the animals’ surface that form false edges which disguise the shape of the body and impede detection.

Influence of drought stress on the metabolite and ion composition in nectar and nectaries of different day‐ and night‐flowering Nicotiana species

Plant Biology, Volume 28, Issue 3, Page 897-912, April 2026.
Drought stress leads to reduced nectar secretion and alters nectar composition of day‐ and night‐flowering Nicotiana species, which may impair plant–pollinator interactions. Abstract The frequencies of droughts worldwide will increase in the future due to climate changes. Nectar composition of plant species varies in relation to pollinator and can also
