Danos causados por diferentes níveis de desfolha artificial para simulação do ataque de formigas cortadeiras em Pinus taeda e Eucalyptus grandis

open access: yesPesquisa Florestal Brasileira, 2011
A desfolha artificial permite mensurar a intensidade do dano devido à desfolha causada por insetos. No presente estudo, buscou-se avaliar os danos causados por formigas cortadeiras em plantios de Pinus taeda e Eucalyptus grandis com 30 dias de idade. Foi

Large‐flowered stapeliad Edithcolea grandis (Apocynaceae: Asclepiadoideae) is pollinated by dung‐ and blood‐feeding African face flies (Muscidae: Musca xanthomelas)

open access: yesTAXON, Volume 75, Issue 5, October 2026.
Abstract The more than 360 species of stem‐succulent stapeliads in the tribe Ceropegieae represent a perfect example for species radiation and diversification in response to pollination by flies. In the majority of species, the myiophilous flowers have visual and olfactory characteristics that suggest carrion or dung mimicry.

Spatiotemporal Variability of Water Transit Time Distribution Across an Alpine Stream Network

open access: yesWater Resources Research, Volume 62, Issue 10, October 2026.
Abstract Water transit time (TT), the time elapsed from its entrance into a catchment and its exit through a stream section, is a useful indicator of catchment transport dynamics. Its distribution (TTD) is typically estimated at a single cross section where tracer data are available.

Herbivore species asynchrony underpins multitrophic stability across plants, herbivores and predators

open access: yesJournal of Animal Ecology, Volume 95, Issue 10, Page 1970-1983, October 2026.
Across a grassland food web, multitrophic stability was most closely associated with herbivore species asynchrony. By identifying herbivores as a key source of temporal buffering between plants and predators, this study shows that intermediate consumers can play a central role in stabilizing the complex food web.

Inferring Adaptation at Community Composition Level From the Relationship Between Succession Rate and Global Change Intensity

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
A 10‐year nitrogen addition experiment in Eurasian steppe reveals that plant and microbial community succession rates first increase then decrease with rising N intensity, indicating an adaptive threshold. Deterministic processes driven by soil physicochemical changes dominate this response, with management strategies modulating adaptation via ...

Extensive Use of Ageing Fence Poles in a Protected Area in South Africa by Reptiles and Birds

open access: yesAfrican Journal of Ecology, Volume 64, Issue 7, October 2026.
ABSTRACT Formal protected area management often requires fences and roads, and these can have negative impacts on animals. During many visits to Ndumo Game Reserve, in northwestern KwaZulu‐Natal, South Africa, the authors noticed substantial numbers of several species of reptiles and birds using the older fence posts along the southern boundary road ...
