Systematics of the New World Rostrate Genus Metaxyphloeus Thomas, 1984 (Coleoptera: Laemophloeidae): Morphological Evidence for Monophyly Supporting a Broader Generic Concept

Austral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT A morphology‐based MP analysis is undertaken to test the monophyly of the lined flat bark beetle genus Metaxyphloeus Thomas, 1984, as well as to hypothesize its intra‐ and intergeneric evolutionary relationships. Based on the results of the present work, Metaxyphloeus, as currently composed, is hypothesized as a monophyletic assemblage of ...

Microhabitat Variation in Feeding Places Shape Ant‐Hemiptera Interactions Within Cocoa Agroecosystems

Biotropica, Volume 58, Issue 3, May 2026.
Ant‐hemipteran mutualistic networks in cocoa crops maintain a stable structural organization across different microhabitats (flowers, leaves, and fruits) and management types. This stability is not intrinsic to the network, but rather an emergent result of the behavior of a few generalist ant species acting as structural buffers.

Diversity, Abundance and Distribution of Sharks in a Multispecies Nursery Area in the Eastern Central Atlantic

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 4, April 2026.
ABSTRACT Shark nursery habitats are priority targets for area‐based conservation as they protect key age classes that exhibit restricted area use. However, the lack of detailed, species‐specific biological and ecological data often undermines the efficacy of coastal management strategies. This study employed complementary Baited Remote Underwater Video

Valoración del estado agronómico de las plantaciones de cacao nacional en el Ecuador

Revista Metropolitana de Ciencias Aplicadas, 2019
Ecuador overview aims to be the second country producer of cocoa at international level, in 2010, producing 132 thousand tons of cocoa and became the eighth country producer in the world. In 2018 it became the fourth with 315 thousand tons, but the expectations for this year 2019 are overcome 400 thousand tons and advance to second place behind Ivory ...

Moth Communities Are More Diverse in the Understory Than in the Canopy of a Tropical Lowland Rainforest in NW Ecuador

Ecology and Evolution, Volume 16, Issue 4, April 2026.
We investigate the stratification of five clades of Lepidoptera: Erebidae‐Arctiinae, Geometridae, Hedylidae, Saturniidae, and Sphingidae in a tropical rain forest of the Chocó region in NW Ecuador. Average species richness was higher in the understory, median sample sizes were similar between strata and we found more species in regenerating forests ...

Global impacts of agricultural and timber plantations on dung beetle biodiversity

Journal of Applied Ecology, Volume 63, Issue 4, April 2026.
In vulnerable areas, protecting natural forests can help to reduce biodiversity loss. When economic and social contexts, such as in the Neotropical and Oriental regions, hinder conservation strategies, establishing small‐scale plantations of native, structurally diverse species connected to remaining forests may enhance dung beetle diversity, likely ...

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...

Trees Inside and Outside of Forests in Guanacaste, Costa Rica: Comparisons Among Conservation Areas, Fencerows, and Urban Parks

Biotropica, Volume 58, Issue 2, March 2026.
We compared the abundance and characteristics of trees in replicated plots across a rural to urban gradient in Guanacaste, Costa Rica. Trees in urban parks, fencerows, and national parks provide complementary benefits and have distinct compositions.
