We report finding Strumigenys thaxteri Wheeler in the Amazonian foothills of southeastern Ecuador, over 2000 km to west previously known records for species Trinidad and Guyana. Field observations suggest it is a sit wait ambush predator that captures insects alight on vegetation upon which they position themselves. Once prey subdued descend with ground level, where presumably nest. Their massive mandibles, robust claws, dense body cover long silky hairs, sting may all contribute detecting,...
Two new species of Leptanilloides are described: L. copalinga Delsinne & Donoso sp. nov., and prometea based on workers collected in the leaf litter soil Andes southern Ecuador. Both belong to biconstricta species-group (formally diagnosed here). The metatibial gland, considered a synapomorphy for Dorylinae, is observed nov. but seems absent We provide COI DNA barcode both revised key worker caste all known genus. also describe single male identified as potential basis morphology....
Many studies have focused on the impacts of climate change biological assemblages, yet little is known about how interacts with other major anthropogenic influences biodiversity, such as habitat disturbance. Using a unique global database 1128 local ant we examined whether mediates effects disturbance assemblage structure at scale. Species richness and evenness were associated positively temperature, negatively However, interaction among precipitation shaped species evenness. The effect was...
Habitat anthropization is a major driver of global biodiversity decline. Although most species are negatively affected, some benefit from anthropogenic habitat modifications by showing intriguing life-history responses. For instance, increased recruitment through higher allocation to reproduction or improved performance during early-life stages could compensate for reduced adult survival, corresponding "compensatory recruitment". To date, evidence compensatory in response modification...
Since its original formulation by Janzen in 1966, the hypothesis that obligate ant‐plants (myrmecophytes) defended effectively against herbivores resident mutualistic ants have reduced their direct, chemical defence has been widely adopted. We tested this quantifying three classes of phenolic compounds (hydrolysable tannins, flavonoids, and condensed tannins) spectrophotometrically foliage 20 ant‐plant non‐ant‐plant species unrelated genera Leonardoxa, Macaranga Acacia (and other closely...
Abstract The relationship between levels of dominance and species richness is highly contentious, especially in ant communities. dominance‐impoverishment rule states that high only occur species‐poor communities, but there appear to be many cases diverse extent which dominant limit local through competitive exclusion remains unclear, such appears more apparent for non‐native rather than native species. Here we perform the first global analysis behavioral richness. We used data from 1,293...
What forces structure ecological assemblages? A key limitation to general insights about assemblage is the availability of data that are collected at a small spatial grain (local assemblages) and large extent (global coverage). Here, we present published unpublished from 51 ,388 ant abundance occurrence records more than 2,693 species 7,953 morphospecies local assemblages 4,212 locations around world. Ants were selected because they diverse abundant globally, comprise fraction animal biomass...
Recently a new species of bombyliid fly, Marleyimyia xylocopae, was described by Marshall & Evenhuis (2015) based on two photographs taken during fieldwork in the Republic South Africa. This has no preserved holotype. The paper generated some buzz, especially among dipterists, because most cases field provide insufficient information for properly diagnosing and documenting Diptera.
ABSTRACT The standardized ‘Ants of the Leaf Litter’ protocol aims to facilitate use ground‐foraging and litter‐dwelling ants in biodiversity assessment monitoring programs. It was initially developed characterize assemblages from tropical rain forests is based on two main techniques: Winkler extractions pitfall traps. Here, we tested what extent this adapted dry affected by rainfall regime. Our 10 study sites were located along an aridity gradient (average annual rainfall: 350–1300mm) Gran...
Solenopsis is a widespread ant genus and the identification of its species notoriously difficult. Hence, investigation their distribution along elevational gradients challenging. Our aims were (1) to test complementarity morphological DNA barcoding approaches for identification, (2) assess diversity an altitudinal gradient in Ecuadorian Andes. Ants collected five localities between 1000 3000 m above sea level. In total, 24 morphospecies identified 14 them barcoded. Seven confirmed by...
The Winkler extraction is one of the two fundamental sampling techniques standardized "Ants Leaf Litter" protocol, which aims to allow qualitative and quantitative comparisons ant (Hymenoptera: Formicidae) assemblages. To achieve this objective, it essential that standard 48-hour provides a reliable picture assemblages under study. Here, we tested what extent efficiency affected by initial moisture content leaf litter sample. In an Ecuadorian mountain rainforest, present rainfall-excluded...

Ants of the genus Tatuidris Brown and Kempf (Formicidae: Agroecomyrmecinae) generally occur at low abundances in forests Central South America. Their morphological peculiarities, such as mandibular brushes, are presumably linked with specialized predatory habits. Our aims were to (1) assess abundance an evergreen premontane forest Ecuador; (2) detail characteristics feeding behavior Tatuidris; (3) define position food web. A total 465 litter samples collected. For first time, live...
An important issue in biodiversity conservation is the early detection of introduced and invasive organisms identification regions that may either be points introduction or particularly prone to invasion. Among insects, ants are easily transported worldwide by humans, several species, such as Solenopsis geminata Pheidole megacephala, can highly invasive. To establish an initial baseline for urban ant monitoring Côte d’Ivoire (Western Africa), fifteen cities - equally distributed over three...
Urban ecosystems house artificial infrastructures such as ports, transport stations and commercial centres which are often introduction foci for exotic species.The connectivity of these structures to other specialised in commodity flows located urban cores, enhances the accidental spreading species can become invasive.Despite this fact, targeted investigations detect establishment invasive tropical landscapes lacking.A survey conducted on ant communities 15 cities throughout Côte d'Ivoire...
We discuss the diversity and distribution of ant genus Oxyepoecus in Paraguay. inquilinus is recorded for first time, new data are given O. rastratus vezenyii . Published bruchi , reticulatus, summarized. Two species described ( bidentatus n. sp. striatus sp.), a key to workers seven Paraguayan provided. At Teniente Enciso National Park, four cooccur. This locality appears as promising site studies documenting biology this poorly known genus, because IUCN “vulnerable“ Red List classification...
The rarely collected ant Lenomyrmex inusitatus Fernández 2001 is recorded for the first time in Ecuador. queen described. new record southernmost limit of distribution genus. A key to workers six species and a known queens are provided.
