Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks

open access: yesConservation Biology, Volume 40, Issue 1, February 2026.
Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Importance of connectivity for carnivore richness and occupancy in fragmented biodiversity hotspots

open access: yesConservation Biology, Volume 39, Issue 6, December 2025.
Abstract Structural connectivity affects wildlife movement between habitat patches, contributing to the persistence of wildlife populations and their resilience to human‐induced and environmental changes. However, its importance to wildlife population persistence remains unclear, particularly in fragmented landscapes, where there are additional co ...

The Formalized Procedural Semantic of Logic Programming Language Gödel [PDF]

open access: yes, 2009
Gödel语言是继Prolog语言之后出现的逻辑程序设计语言,它建立在多态多类的一阶逻辑基础之上,摒弃了Prolog语言中的非逻辑成分,集成了许多语言的有效成分和优点,引入了类型系统,这使得它成为一种高效的说明性逻辑程序设计语言。然而,时至今日,Gödel语言编译系统的开发研究仍然进展缓慢,主要原因是多态多类的类型系统、模块化结构、延迟计算、剪枝操作等多种新语言成分和机制的引入,使逻辑程序设计语言Gödel的复杂程度大大提高 ...
