Resumen: New mastodon finds collected in the Province of Carchi (Northern Ecuador) give further evidence that in South
America Haplomastodon and Cuvieronius are monospecific. Of all the specific names referred to the genus Haplo mastodon, only chimborazi must be considered valid as it alone was based on significant diagnostic material. As far as the genus Cuvieronius is concerned a new type species, Cuvieronius tarijensis, is proposed as the type specimen of Cuvieronius hyodon likely belongs to Haplomastodon.
Descripción: Des nouvelles pieces de mastodonte recoltées dans la Province du Carchi, au Nord de l'Equateur, confirment
qu'en Amérique du Sud les genres Haplomastodon et Cuvieronius sont monospecifiques. Tousles noms specifiques proposes pour le genre Haplomastodon, avec la seule exception de chimborazi, ne sont pas valable parce que fondes sur des exemplaires qui n'ont pas d'importance diagnostique. En ce qui concerne le genre Cuvieronius une nouvelle espece type, Cuvieronius tarijensis, est propos6e parce que l'exemplaire type de l'espece Cuvieronius hyodon appartient vraisemblablement au genre Haplomastodon.1994-02-16T00:00:00ZModelo matriz de datos para depósito de especímenes en la colección de invertebrados

Título: First records of Diptera associated with human corpses in Ecuador
Autor: García-Ruilova, Ana B.; Barragán, Alvaro; Donoso, David A.; et. al.
Resumen: Flies in the order Diptera are of forensic value because many species leave tractable evidence
while harvesting nutrients from decomposing corpses. From December 2015 to January 2017,
41 fly specimens were collected in human bodies at crime scenes and autopsies across the
south of Ecuador. Six species, e.g., Chrysomya albiceps (Widemann 1819), Chrysomya megacephala
(Fabricius, 1794), Synthesiomyia nudiseta (Wulp, 1883), Lucilia purpurascens (Walker,
1836), Hemilucilia segmentaria (Fabricius, 1805), and Stomoxys calcitrans (Linneo, 1758) were
identified to species level using morphological (dichotomous keys) and molecular (mitochondrial
COI barcodes) techniques. One additional specimen remains unidentified to species level,
but COI barcodes assigned it to the genus Paralucilia. These first taxonomically curated records
of flies in real cases constitute a tangible groundwork for the development of forensic
entomology in Ecuador.2020-11-01T00:00:00ZOdontomachus davidsoni sp. nov. (Hymenoptera, Formicidae), a new conspicuous trap-jaw ant from Ecuador

Título: Odontomachus davidsoni sp. nov. (Hymenoptera, Formicidae), a new conspicuous trap-jaw ant from Ecuador
Autor: Hoenle, Philipp O.; Lattke, John E.; Donoso, David A.; et. al.
Resumen: One of the largest species in its genus, Odontomachus davidsoni Hoenle, Lattke & Donoso, sp. nov. is
described from workers and queens collected at lowland forests in the Chocó-Darién bioregion in coastal
Ecuador. The workers are characterized by their uniform red coloration, their large size (16–18 mm body
length), and their frontal head striation that reaches the occipital margin. DNA barcodes (COI) and high
resolution 2D images of the type material are provided, as well as an updated key for the Neotropical species
of Odontomachus. In addition, a three-dimensional digital model of the worker holotype and a paratype
queen scanned with DISC3D based on photogrammetry is presented, for the first time in a species
description. Findings of large and conspicuous new species are uncommon around the world and suggest
that these Ecuadorian rainforests may conceal many more natural treasures that deserve conservation.2020-07-01T00:00:00ZEnemy-free space and the distribution of ants, springtails and termites in the soil of one tropical rainforest
http://bibdigital.epn.edu.ec/handle/15000/21435
Título: Enemy-free space and the distribution of ants, springtails and termites in the soil of one tropical rainforest
Autor: Basset, Yves; Palacios-Vargas, José G.; Donoso, David A.; et. al.
Resumen: The soil fauna of tropical rainforests is difficult to study because of its extreme species richness and taxonomic impediment. Studies of multi-taxon assemblages in the soil of tropical rainforests are relatively rare and studies of interspecific interactions, such as predation, even rarer. Here we attempt to infer prey predator interactions and enemy-free space from the faunal composition of 100 litter/soil samples obtained from Barro Colorado Island in Panama during the dry and wet seasons. We focused on assemblages of ants (assigned to categories of non-predators, potential and confirmed predators), springtails and termites, which were characterized by their Barcode Index Numbers. Overall in 0.2 m3 of soil/litter we collected 2129 ants, 5592 springtails and 260 termites, which represented 80, 104 and 15 species, respectively. The faunal composition of confirmed ant predators was spatially coincident with that of Collembola. However, despite considerable seasonal shifts in the rank abundance of Collembola species, seasonal shifts of confirmed ant predators were low, resulting in a poor match of seasonal shifts between ants and their prey items. No location could be considered as being relatively free of ant enemies for springtails or termites, but the dry season supported higher prey-predator ratios than the wet season. We inferred only 4 possible prey-predator interactions, out of 7616 potential interactions in the study system. The relative dispersion of confirmed ant predators, which only weakly influenced springtail and termite assemblages, suggests low specificity in ant-prey interactions. This confirms that “brown food webs” may be structured by bottom-up effects rather than by top-down effects.2020-08-01T00:00:00ZWorld Scientists’ Warning of a Climate Emergency

Título: Phyllostomid bats as a model to test zoogeographic units in Ecuador
Autor: Carrera E., Juan P.; Phillips, Carleton; Solari, Sergio; et. al.
Resumen: Nine Zoogeographic Units (ZU) have been hypothesized for Ecuador, with seven
of these units located within the continental portion of the country. Each ZU was dened
by climate, topography, elevation, and vegetation type. In spite of their historical ap-
plication, the validity of ZUs has not been tested. The goal of the present study was to
treat the ZUs as hypotheses and test their validity. For this purpose, species of the bat
family Phyllostomidae were used as a model. A total of 13,262 validated bat records,
representing 109 species and six feeding guilds (with conrmed taxonomic identications
and geographic information), were analyzed using multivariate statistical analyses and
geographic modeling. Results obtained from the Multidimensional Scaling Analysis,
Detrended Correspondence Analysis, and Pairwise comparisons provided evidence
that the ZUs as proposed were valid, based on information from phyllostomid bats,
although no species was restricted to the Temperate Forests and High Andes. In addi-
tion, geographic models showed that Tropical Eastern Forests and Subtropical Eastern
Forests were the most likely areas to be inhabited by phyllostomids. Bat species in the
High Flying Frugivore and Insecti-Carnivore trophic guilds displayed a clear spatial
pattern highly related to ZUs. The ndings of this study provide important informa-
tion regarding the validity of these ZUs for establishing priorities concerning research,
conservation, and management in this group of mammals.2019-10-01T00:00:00ZDeclinación masiva de insectos: ¿Se acerca el Armagedón?

Título: Land use impacts poison frog chemical defenses through changes in leaf litter ant communities
Autor: Moskowitz, Nora A.; Dorritie, Barbara; Donoso, David A.; et. al.
Resumen: Much of the world’s biodiversity is held within tropical rainforests, which are increasingly fragmented
by agricultural practices. In these threatened landscapes, there aremany organisms that acquire
chemical defenses fromtheir diet and are therefore intimately connectedwith their local food webs.
Poison frogs (Family Dendrobatidae) are one such example, as they acquire alkaloid-based chemical
defenses from their diet of leaf litter ants andmites. It is currently unknown how habitat fragmentation
impacts chemical defense across trophic levels, from arthropods to frogs. We examined the
chemical defenses and diet of the Diablito poison frog (Oophaga sylvatica), and the diversity of their
leaf litter ant communities in secondary forest and reclaimed cattle pasture. Notably, this research
was performed in collaboration with two high school science classrooms. We found that the leaf
litter of forest and pasture frog habitats differed significantly in ant community structure. We also
found that forest and pasture frogs differed significantly in diet and alkaloid profiles, where forest
frogs contained more of specific alkaloids and ate more ants in both number and volume. Finally,
ant species composition of frog diets resembled the surrounding leaf litter, but diets were less
variable. This suggests that frogs tend to consume particular ant species within each habitat. To
better understand how ants contribute to the alkaloid chemical profiles of frogs, we chemically
profiled several ant species and found some alkaloids to be common across many ant species while
others are restricted to a few species. At least one alkaloid (223H) found in ants from disturbed sites
was also found in skins from pasture frogs. Our experiments are the first to link anthropogenic land
use changes to dendrobatid poison frog chemical defenses through variation in leaf litter communities,
which has implications for conservation management of these threatened amphibians.2020-04-01T00:00:00ZCambio climático y sus afectaciones a los ecosistemas
