Assessing the evolutionary distinctiveness of a highly threatened plant group: The urgency to preserve a unique lineage of evolution in Brazil

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1223-1237, July 2026.
Brazil's diverse flora is under several threats, with many unique lineages facing extinction, particularly in biodiverse regions like the Cerrado and campo rupestre. This study sheds light on the conservation needs of Cambessedesia (Melastomataceae), an endemic genus with 95% of its species endangered, using an approach to rank and prioritise species ...

Digitising biological collections to advance National Species Inventories: A case study from the flora of Chile

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1210-1222, July 2026.
In response to Chile's public policy to establish a national biodiversity inventory and monitoring system, we launched the HerbarioDigital.cl portal. We have digitised over 120,000 specimens representing more than 3,900 species from two Chilean herbaria, integrating them through a curated local taxonomic index.

Toxicity of aqueous extracts of Ilex paraguariensis A.St.‐Hil. about Euphorbia heterophylla L.

open access: yesPest Management Science, Volume 82, Issue 7, Page 6196-6206, July 2026.
Aqueous extracts of Ilex paraguariensis A.St.‐Hil. strongly inhibit Euphorbia heterophylla L. germination and early seedling growth, but show mild phytotoxicity on mature plants, paradoxically promoting biomass via antioxidants. Abstract BACKGROUND The escalating challenge of herbicide‐resistant weeds, exemplified by Euphorbia heterophylla L.

High and dry: Environmental conditions drive opportunities for disease transmission in desert bighorn sheep

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
By using probabilistic models to predict contacts as a function of spatially and temporally varying environmental conditions, we show that population‐level conditions at the time of disease introduction can structure opportunities for transmission within each population.

Environmental detection of the amphibian chytrid fungus in water bodies is associated with host infection along a deforestation gradient

open access: yesJournal of Applied Ecology, Volume 63, Issue 7, July 2026.
Linking environmental pathogen detection with host infection patterns can improve surveillance of diseases involving environmental transmission, particularly where direct host sampling is logistically challenging. This approach enables the identification of areas of elevated transmission risk and supports targeted monitoring and management under ...

Challenging and diagnosing structured population models by testing predictions from stochastic demography

open access: yesMethods in Ecology and Evolution, Volume 17, Issue 7, Page 2234-2252, July 2026.
Abstract Structured population models are parameterized to accurately project expected population sizes, stage/state distributions and population growth rates, but they also predict the variation in outcomes among individuals, such as the variance and skewness of lifetime reproductive output (LRO) and lifespan, the probability of never reproducing, and

To release or not to release? A call for caution when considering wildlife reintroductions

open access: yesConservation Science and Practice, Volume 8, Issue 7, July 2026.
Conservation efforts often focus on flagship species and short‐term measures such as captive breeding and reintroductions, yet these approaches may benefit from being complemented with a broader view of the factors that influence long‐term recovery. Using examples from management programs in the Iberian Peninsula, we highlight the value of considering ...

Pathways of Introduction and Expansion Dynamics of Non‐Native Species in an Island Ecosystem

open access: yesDiversity and Distributions, Volume 32, Issue 7, July 2026.
ABSTRACT Aim Biological invasions are a global challenge, largely driven by human‐mediated introductions beyond species' native ranges. Island ecosystems are particularly vulnerable, as invasions have caused some of the most profound and detrimental impacts on native and endemic biota.

Insects and Survival: A Review of Primary and Secondary Defense Strategies

open access: yesEntomologia Experimentalis et Applicata, Volume 174, Issue 7, Page 601-624, July 2026.
Based on a review of three decades of literature, insect defense mechanisms are classified into primary (I) and secondary (II) mechanisms of behavioral, morphological, and chemical nature. These mechanisms have been recorded in 22 (I) and 20 (II) orders, respectively.
