Entamoeba, giardia and toxoplasma: clones or cryptic species?

Parasitology Today, 1993
The availability of molecular markers has renewed interest in the taxonomy of parasitic protozoa at the subspecific and specific levels. Nevertheless, the conclusions reached are heavily dependent upon the way the data are analyzed. Some authors have emphasized the value of genetic distances to propose the creation o f new species, while others have ...

Prey detection by the predator remains constant across prey densities: evidence from a field experiment in the Arctic tundra

Oikos, EarlyView.
The functional response describes how predator acquisition rates change with prey availability and integrates behavioural processes that occur during predator–prey encounters. Among these processes, prey detection represents a critical yet often overlooked component that can directly influence population dynamics. Variation in detection probability has

Dispersal‐limited birds at high risk from cattle farming deforestation in tropical forests

Oikos, EarlyView.
Deforestation driven by farming is a major threat to tropical biodiversity. Although this impact is well documented, assessments at local or regional scales often underestimate biodiversity loss at broader national scales by up to 60%. A key question remains: how do farming activities affect functional diversity and species traits across different ...

From co‐occurrence to temporal coupling in a coral defender guild

Oikos, EarlyView.
Coral‐dwelling decapods can improve host fitness by defending corals against corallivores and sediment accumulation, yet the temporal dynamics linking co‐resident defenders remain poorly understood. Guard crabs Trapezia and snapping shrimp Alpheus provide complementary benefits to pocilloporid corals, and previous, largely cross‐sectional work has ...

Integrating vision, audition and olfaction traits: a roadmap for contrasting sensory ecologies of birds and rodents

Oikos, EarlyView.
Sensory ecology seeks to understand how organisms detect and use information from their environment, yet comparative analyses across multiple sensory modalities remain rare. Here, we present a roadmap for contrasting the sensory ecologies of birds and rodents using surrogate morphological and acoustic traits associated with vision, audition, and ...

Digital surveillance of animals and nature recovery

People and Nature, EarlyView.
Abstract Digital surveillance technologies (DSTs) are widely applied in nature recovery for their potential to generate novel data on species and ecosystems through digital tracking, automation (e.g. from hazardous locations) and from newly recruited citizen scientists.

Designing for biodiversity data in place: Species, encounters, and interfaces

People and Nature, EarlyView.
Abstract Species occurrence data, which records the presence of an organism at a point in space and time, is central to environmental science and its opening up to new forms of participation such as citizen science. Such data are increasingly aggregated and mobilised, reaching diverse audiences.

Revealing the dark biodiversity around us through a national school‐based citizen science project

People and Nature, EarlyView.
Abstract School‐based citizen science holds great potential for expanding biodiversity knowledge while engaging young people in authentic scientific practices. This is particularly important for revealing ‘dark biodiversity’, defined as the vast yet often overlooked biodiversity that remains hidden due to its small size or cryptic nature, including ...

Knock‐knock, who is inside? Exploiting citizen science data to shed light on Aedes albopictus indoor presence in southern Europe

People and Nature, EarlyView.
Abstract Animal behaviour in human‐dominated landscapes is difficult to study at large spatial and temporal scales, especially for small species characterised by elusive movements. Citizen science can help overcome these limitations by turning routine human–animal encounters into observations of where and when species are active.

The Long Trajectory of Rubber Physics: 3500+ Years and Counting

Journal of Polymer Science, EarlyView.
Natural rubber's trajectory is traced from Mesoamerican use of Castilla elastica through vulcanization and the pneumatic tire to macromolecular physics and modern solid‐state refrigeration. Illustrations of C. elastica and an H. brasiliensis plantation frame the historical progression from indigenous material, then industrial crop and on to advanced ...
